325i vs 325e (Manifolds and T/B.)

[Giga Shadow]

Does anyone have a side by side picture? Have you seen one on the web somwere? I'd also like to know the sizes of both just for comparison :wink:

I'm going to do this and the 325i intake on my Eta but can't get any feed-back from the people that's done it. Best replys I've gotten is "People say the gains are pretty decent" and "I did it but the dam thing would never idle right"
Bimmerjim! I remember you posting on bimmerforums that you've done the T/B on your friends Eta; how was the before and after?

Going to the yard this weekend with my cargos so I guess I'll find out on my own, but I'd like to know what to expect from people who's done it (isn't it sapposed to be a commen mod for the 2.7? :x )
Opinions? :?:
Do it for the children :cry:

[Giga Shadow]

Found alittle bit of info, but don't know if it applys to me or not.
http://www.e30zone.co.uk/tbfaq.asp

The test comprised a simple before and after power run. The first test with the standard 325 item showed the car to be producing a very respectable 234.6 bhp at 6154 rpm and 220.8 lb/ft of torque at 4645 rpm. This is a lot of power from such a package which is largely down to a combination of Jags mechanics and Nigel’s expert mapping over the years.

At first sight, the bigger throttle doesn’t look that much bigger and there was some skepticism as to what difference it would make. It’s quite a simple job to fit - only just enough time for coffee and the car was ready for the second run!

Nigel was beaming when the figures popped out of the computer. This simple mod had hiked the bhp up to 240.7 at 6282 and the torque up to 227lb at 4470 rpm. The curve characteristics had changed for the better too.

That's ALLOT of hp for just a few MM of diffrence so you can understant why I'm skepticel. :?
I heard that th Eta T/B can acctually fit INSIDE the 325i's :shock:
So should HP go up 20hp? :lol: I guess by Uk standerds, huh?


http://www.e30zone.co.uk/Images/POWER%20CURVE.jpg

So what do you think? Bull shit or what? :lol:

[MadmaX]

No time for picture taking, but the e throttle body does fit inside the i one. Feel free to buy a complete throttlebody&manifold from an i and let us know what you think.

[bimmerjim®]

Bimmerjim! I remember you posting on bimmerforums that you've done the T/B on your friends Eta; how was the before and after?

that was on deano's eta,. hes on the board here.. we did alot of changes to the motor that week, i never drove the car before hand, and im not shure how much of a difference that TB makes.

[Giga Shadow]

I fuckin hate the e30 community, a bunch of pussy little kids. :x
you ask for some feedback on a mod that is very commen and get nothing, even from the people that's done it, or some childish post! Not you guys but people from other forums. :oops:
I found that if you take the i throttle body and everything connected to it, back to the trunk, it is good for an extra 30hp when swapped into an eta.

and people who think I'm retarded because they cant read and miss understand what's infront of there face. Who the hell said that's an Eta dyno? :roll:
it only increased 6 hp and 7 lb*ft on a balls-out eta that is making 235 hp? first, who the heck can make that kind of power out of an eta at that rpm? i guess that's a 2.7i swap with the 323 head? second, seems like it would have done more if the size difference is that big. third, on our nearly stock eta's, it doesnt look like it will do much at all.

I'm going to try to barrow some cargo pants today or tomarrow but I'll
take a crap load of pictures and reivews for people that want to do this but they're not sure BECAUSE THEY CAN'T FUCKIN FIND ANYONE WHO'LL TELL THEM ANYTHING ABOUT IT EXCEPT THAT YOU'LL OBVIOUSLY HAVE TO PORT MATCH THE T/B TO THE INTAKE.

Do you have the Eta t/b :?:

[swartz]

should do the I intake manifold to. i sold one with the tb and rail/injectors for $65 a few yers ago

[Giga Shadow]

The first week of september one of the junkyard is having a sale.
50% off all items so I'll most likely get it then ($20)
I'm getting the T/B free so why not just get it on friday or maybe even tomarrow. :wink:

Beside, I'm kinda pissed off that nobody has any write-ups or good information on doing this. I feel I should do this just to document with pictures.

[Giga Shadow]

No time for picture taking, but the e throttle body does fit inside the i one.

Does the Eta t/b fit on the 'i' monifold? Just incase the t/b isn't there on monday and I can get started tomarrow and still drive it around. :?
I got an email from calvin tan and said I'll have to port match to the head but it's almost nothing so If I don't it's cool because it's not a big diffrence (I'll do it anyways.)

This is calvin btw: The guy with the most tricked out M20.

I can understand why you're frustrated. On the bright side you get to author what will probably become a sticky thread.

I've got two eta(supereta, in case their different) manifolds, one supereta throttlebody, and one complete "i" throttlebody/manifold. Well, plus everything on the '87 325is parts car that jim and I are tearing down. But I think Jim want's that one to experiment with direct port nitrous or something.

[Chris]

On the bright side you get to author what will probably become a sticky thread.

I agree. :lol:

[MadmaX]

Ever done something for someone else and God goes, "Good job, here's one for you."?

What I mean is, I got off my lazy butt and did some measuring for ya donkeypunch. The SuperETA throttlebody is 2 and almost an eighth inches diameter. The "I" throttlebody is a bit over 2 and a half. I don't know how much more area that equates to, but I think it involves pi :D . The "I" throttlebody goes on the eta manifold, and viseversa.

Here's what I was referring to at the beginning of my post.

Some dolt put an eta gasket between my "I" throttlebody and manifold. I was just going to bolt that thing on all at once when I do the 2.7i project here shortly, but I wouldn't have ever caught that if I hadn't seperated them to measure. It would have been a little paper restrictor plate.

There you go. You can only help yourself by helping other... or something like that. :lol:
Thanks for looking out. I'm so exited! My first REAL mod :P

[Giga Shadow]

Sorry to bring up an old post, but did I even get the right one?
I'm afraid I might of gotten one off a super Eta. :oops:

Please confirm! :(

[Giga Shadow]

Ok, I posted this question on another board and got that the Super eta manifold is actually smaller then the reguler ets's so it's safe to say that I got the right one..

[bimmerjim®]

this is good info, making it a sticky.

[PatNy]

so what happened?...im gonna do this too...i was gonna do a I head TB and exhaust.....and an i ecu then i was looking to do some boost!!

[Giga Shadow]

That's exectly what I'm planing pat!

I just need to buy the manifold gaskets and the fun starts. :twisted:
I couldn't get the throttle body so it's just going to be the 325i intake manifold w/ the eta throttle body.
Then when I get some money I'll buy the throttle, then the exhaust, then the head... All of these parts are REALLY cheap so.... soon :P

I'm thinking I need to make a spacer for the throttle body ciz the boot might not reach... :? I'll post every step and many many pictures up in here sticky or not. Probably the middle of next week (big camping trip this weekend!)

[Giga Shadow]

You don't have to lift the car, but It'll make the job allot easyer on your
back. Just put the left side on a jack so it's angled.

------------------------------------------------------------------------------------

Take out the airbox w/boot, disconect everything from the throttle body, take it off, (10mm nuts )and toss it aside
:wink: http://img.photobucket.com/albums/v163/glowkid/IM000325.jpg

------------------------------------------------------------------------------------

Take the check code thing off.
The lid is a 'C clip you just pull and the the plug slides down, reveling a 12mm nut to take the braket off
http://img.photobucket.com/albums/v163/glowkid/IM000319.jpg

----------------------------------------------------------------------------------

Remove the water line blocking the nut on the intake.
You can now remove all the nuts on the left side (three runners).
http://img.photobucket.com/albums/v163/glowkid/IM000324.jpg

-----------------------------------------------------------------------------------

Your going to want to use a 12mm pivot socket with a long extension for the intake nuts (I used an 8 )
Pretty simple so far. This part won't even take you 5 min.
http://img.photobucket.com/albums/v163/glowkid/IM000318.jpg

-----------------------------------------------------------------------------------

Next, remove these two 10mm nuts.
Slide the bracket off and toss it aside...
This'll give you some room to take off the last nuts.
You won't have room to do the next two if you use anything longer then an 8 extention becuase the
Power steering and Master-cyclinder fluid resuviors,
On the last runner I had to use a longer extention to get to it (I used an 11) :wink:
I know at first it'll seem like you can't get it in there but don't be afraid to muscle the hoses out of the way and guide the socket with your fingers.
http://img.photobucket.com/albums/v163/glowkid/IM0003212.jpg

------------------------------------------------------------------------------------

.....You're done with the that part! :occasion9:
Now pull the manifold off the head just enough so the senser on the thermostat housing can clear the fuel rail and start unplugging all the injecters and everything that goes to the harness and fuel lines that go to the cold start injector and fuel-rail (Remember or mark where each plug goes, just in case). Make sure all of them are uplugged or you'll end up snaping a wire when you pull it off.

Now the fun part! :o
I've talking to people that've done this swap before and said they got
pretty noticable power gains even with the head unported.
And as you've already noticed, it's a HUGE diffrence between the head and the manifold so I'm going to try to get best gain that I can with this mod, So if you don't want to risk getting metal shaveings in you're cyclenders or don't want to take it apart DO NOT DO THIS! this is only for the brave :shock:
http://img.photobucket.com/albums/v163/glowkid/IM000334.jpg

-------------------------------------------------------------------------------------

Just started to port. This is alittle bit into it and it's going like butter.
Use whatever you think is best for completly sealing the port off.
I cramed the ports full of cotton balls so I have to use tweezers to get out and the last ball I fluffed it out so it catches most of the shavings.

Also used a vac. and sucked overything out when I was done including the first ball, then I plucked the other balls out while still vacuuming. Be carefull if you dodecide to do this, don't rush it and make sure that every piece of matal is gone before taking out the last couple cotten balls, use wet Q-tips if you have too.

Somthing to think about:
Wearst thing that can happen is shavings will stick to the cyclinder walls and scratch them to the trash! Shaving can do the same with the valve stem, So take your time! :shock:

Bright side:
That god loves you and the shavings will get blown right out without sticking to any valve stems or the wall. :lol:

http://img.photobucket.com/albums/v163/glowkid/IM000355.jpg


-------------------------------------------------------


I think I'm done porting it.. Maybe I'll open it up some more but with a big bulky drill it's kinda hard to get in there.
You can see that there's little to no shaving going past the first cotten ball that was vacuumed out before the picture.
Compare it to the origanal.. :wink:
What do you think? Am I wasting my time porting it or what? :?:

Remember that there's some overlap on the intake manifold to the gasket, so remember to check and match as best
you can to the manifold, not the gasket (or unless you're doing the intake too)
If you don't get them exactly right that's o.k, allot better then that giant wall blocking flow IMO.

------------------------------------------------------------------------------------

Switch your injectors to the 325i manifold.
Undo these 10mm bolts (4) and flick these 'C-clip off
the injectors.
The injectors will pop right out, but it's going to take some muscle perhaps.
You can use some vasoline or motor oil to slide them pack in the cups (makes it allot easyer)
http://img.photobucket.com/albums/v163/glowkid/IM000359.jpg

------------------------------------------------------------------------------------

No put the manifold and and start putting things back together.
Real simple bolt on. I don't think there really was a need for a write up but just to let people know/see EXACTLY how this is done.

Don't forget the crank case breather!!!!!!
I did and hade to take the manifold back off :oops:
It need to be set in the block hole first and them slide the manifold
on it.... It won't fit if you try to put it on when everything's all locked down.
http://img.photobucket.com/albums/v163/glowkid/fgghghgh.jpg


Notice I forgot mine... :oops:
http://img.photobucket.com/albums/v163/glowkid/IM000373.jpg


-----------------------------------------------------------------------------------

If you didn't use the 325i throttle body like me I bet your wondering where you're going to plug the vacuum line for the FPR, right?
What I did was trash the back plate all together, geting rid of the cold start injector and the Idle control valve.

The car started just fine for me without the cold start after it's been sitting in my driveway for over a week without start........ At night, so I think it's safe to assume I won't need it..

The I.C.V was taking trashed too, caping poth nipples then adjusting the idle from the throttle body (there's a screw there)
Idle like a champ and it'll clean the bay up 100%



I'll keep editing and post more pictures I think you should see

[x628x]

were you gonna port the manifold?

[Giga Shadow]

There's no reason too unless you put the 'i' throttle body up to the 'e' manifold.
However there WILL be some porting needed on the HEAD to match the 'i' manifold. How much? I have no idea... But I've been told almost nothing.. :?

[x628x]

do you want an 'i' throttle body?

[Giga Shadow]

If I've left anything out, feel free to flame.
and If you need to see more better pictures, I'll post them up.

I'm trying to make the most comprehensive write up I can :lol:

[chromius_e30]

Ok, I posted this question on another board and got that the Super eta manifold is actually smaller then the reguler ets's so it's safe to say that I got the right one..

BTW:

http://img.photobucket.com/albums/v163/glowkid/IM000309.jpg

Can someone confirm that statement? I'm curious. Why would they use a smaller manifold on a supereta, since it has a "i" head, and more horsepower than a regular eta, and in fact shares many of the same exact parts with the "i". And of the pic you have above, the supereta TB looks like the larger one, it looks nothing like the smaller one, because the coolant lines and breather hose for the supereta is on the same side as the "i" ie the left side (when looking in the opening)....someone please straghten this out... :?

[Giga Shadow]

I've read that the Super eta t/b and intake are completly diffrent then both Eta and 325i.
If it's true that the super eta intake and t/b is smaller then I bet they did they to still keep low end torque..
A super eta was still made to be a low reving stump puller, Just alittle faster because people were complaining how slow the eta was (I'm guessing)

[chromius_e30]

yeah, I guess thats possible. I would be curious to know for sure though. I know the tb is slightly smaller than an "i" (not as small as a regular eta though) However, I have no clue about the manifold though..since it mates to an "i" head, I would have thought it would be the same as an "i"...ah well, just another thing to change I guess when I finnaly get around to the stroker project on the supereta. :roll:

[Giga Shadow]

http://img.photobucket.com/albums/v163/glowkid/IM000349.jpg

There's a side by side. You can really see the diffrence, eh?
I don't know what the Super ETA manifold looks like so maybe you
can judge by these pictures. (I think you know wich is wich :wink: )

[Chris]

Nice comparision.

You can really see the difference when they're side by side.

[Bob Loblaw]

ah well, just another thing to change I guess when I finnaly get around to the stroker project on the supereta. :roll:

Do it! Slacker! :P

[Giga Shadow]

Well, just my luck I run into 3 Super Eta motors today. :lol:
I would say that the manifold has a smaller center and skinnyer runners then the normal Eta's for sure.
If you notice it has the BMW faceing the Throttle body just like the 325i.
It's ports are as big as the 325i are but about 1/2 '' into it the runners it get real skiny.
http://img.photobucket.com/albums/v163/glowkid/IM000364.jpg
http://img.photobucket.com/albums/v163/glowkid/IM000365.jpg

The throttle body is also styled the same as the 325i with the water lines on the left side and the raised throttle linkage but still a tiny bit smaller then the regular Eta for some reason, pretty wierd..., eh? :?
here's the Super eta throttle... If you compare it to my hand, you can
really see how small it is (I can't even put my dick in there)

http://img.photobucket.com/albums/v163/glowkid/IM000366.jpg

[Giga Shadow]

Got it started and the idle is alittle high (what does that mean?) :twisted:
Didn't take it for a spin yet since I need to connect all the water lines and fiqure out why my alternater isn't generating. :?

The two new injectors I got were from another Eta but had diffrent numbers on it; Seems to run just fine.
I used the 325i back plateon the intake (no cold start) and started up just fine.. Idle didn't drop... it was perfect so I trashed the cold start. Makes the bay looks allot cleaner too.

I didn't use a trottle body gasket, just RTV.. seals really nice.
Can't wait to drive it! I don't expect much... In fact I don't really remember how my car feels like....
It's been like a 2 weeks since I've drivin it and between that time I've been driving other cars.. (hope I can tell the diffence :oops: )

[screaming_bmwe30]

hey donkey, You can lower your idle by backing off that TB screw. The more air that gets into the engine, the higher the idle will be (you probably figured this out by the time you read this.) The reason i'm posting is because i just bought an 86 325e. It drives pretty nice, but it probably needs a tune up. Do you have a performance chip in yours? i was thinking about getting one, since they supposedly raise the power quite a bit. I remember when i put one on my i before it was turbo, and it made a slight diff, but just wondering if you think it's worth the 50$?

[straight6]

$50 is pretty fucking cheap for a chip!!

[Giga Shadow]

Is it off e-bay?
What is it? I think I might get one too if it's $50 :P

[swartz]

check all the vaccum lines on the throttle body and there is an allen screw on the tb that adjusts the idle

[Giga Shadow]

Thanks, I already fixed that.

BTW: You don't really "NEED" the cold start,
but it'll run rough untill it get's warm..

It isn't worth hooking the cold start/plugs/fuel line back up (for me)
becuase after about 15 seconds of driving or keeping over 600rpms (yes! Almost no time at all) the car will run like normal.

[screaming_bmwe30]

yeah donkey, i just bought a chip off ebay for 51$ shipped, and that was the buy it now. I think if you hold out till the end, you can get it for 41$ at the cheapest. The sellers name is like eurosport or something, and he sells lukas's shields as well. He's emailed me before because he wanted to make a kit out of the shield i sell on ebay, and his racing chips, etc, so i think he's a pretty good seller.

[Giga Shadow]

Still could be a bunk chip though.. :?
Give reviews!

[Giga Shadow]

Here's the diffence between the 325i and 325e exhaust manifolds..
It took me about 4 days to fiqure out what the diffrences were, and the ONLY diffrence is that the 325i runners are stright from the ports to the downpipe comparted the ETA.

The neck on the downpipe flange is the same!!!
Port size, is the same!!!
Only diffrence is that the ETA's runners have a slight curve downwerds
and the 325i's are stright..

That's it...
The pictures make it obviouse. :wink:
Personaly, I don't think it makes much diffrence and
you should spend your mony on other things that'll make a diffrence.
Like a short-shifter or something. :P

wierd.

[E30bimmerdude]

ok so i have read this post about 20 times, trying to figure out what exactly i need to do this swap, and i was wondering if someone would be able to compile a list to make it easy for me.... i really want to do this mod, as i needing more HP :lol:, but it wont take place till the summer, but i am also wondering how the gains were and whether it was fully worth it. And perhaps maybe how much it cost and estimated time....THANKS :D

[Giga Shadow]

cost was:

$17- intake
$60- exhaust <---I got ripped off big time :(
$20- throttle body.

Gasket's where cheap.
Probably like $14-15 all together.

There's a dip in power right inbetween 2.3k and 3k but everywhere
in the revs there's a noticable power gain expectually 4k+ Feels
like it's going to blast off compared to stock, but then comes the limiter :lol:

Took me acouple day's to put together, but I lost some drive after the first one,
had to order the gaskets, and went on a camping trip.
Probably'll take you an afternoon if you have all the stuff together.

[E30bimmerdude]

Thanks for the info, maybe ill start going to the local yards.... hey i have one more ? i dont remember if you said u used an I throttle body or the E, and would it be better to go for the i... :roll:, and i take it you didnt have to change any of the ECU components, i already have the Jim C chip and exhaust, but maybe ill throw on the i headers... any thoughts?

[Giga Shadow]

The E throttle body is garbage, use the i one.
You'll need to mod the air boot if you want to use the
stocker.

Unless you can get vacuum for the fpr and still use the eta's
I.C.V and cold start. You won't have to fuck with the sensers
except just swap the W.O.T switch over.

Cheap, easy, noticable.. do it. :P
Probably like a 5hp all around.

[E30bimmerdude]

Kinda off topic, but have any of you thought about doing the AKA RAlly..... :lol: Coast to Coast... might be fun to get a huge group of BMW's and show them off.....

[E30bimmerdude]

yeah its a bit pricey though... it might be fun to start our own rally of some sort, where it doesnt cost $3000.....anyways just a thought, looking forward to the new engine mods in a few months. :lol: maybe we could do it simply on the West Coast.. maybe Phoenix to Seattle!

[superj]

thats all cool and stuff but putting it on the west coast still means its gonna cost the central states people 3000.00$ to play.

[machsound]

Where do you put the vacume for the brake booster. Just leave it off. I don't have the "i" throttle body yet!!!!!!! I get brakes but barly and I have to push hard. I put it on the throttle body leading towards the valve cover and took that hose off.

Please help I like to be able to stop and I cant now

[Giga Shadow]

What I did was left it disconnected.
You can tap a line into the intake, but that's too hardcore for me. Just get a 325i throttle body so you don't have to mod anything.

You'll get used to it. Just press harder, same stoping power. 8-[

[machsound]

Great Donkeypunch I was hopeing for some ingenius reply that I hadnt thought of I am going tomorrow to see if I can find a throttle body.

There is a brake booster port on the i TB on the firewall side I think it's slip on fit too...so you could run any hose with a clamp to make it work.

So would there be a benefit of using a regular E intake and throttle body on a Super ETA? Because I have one of each in my garage. My 85 325E is a parts car though but it has less miles on it, while my 88 325 Super ETA is my daily driver. I wanna try and buy this beat up 325IS Down the street some day for the plastic bumpers and all that good stuff. But would there be a performance gain at all do you think with the regular E stuff on a Super ETA?
