what else can i do?

[Jcapelo]

Hey guy i have a 1988 325e super eta....

so far i have added a 3.73 lsd and a "i" exaust..

My question is what else can i do to make it faster without spending a shitload of money..?

I heard alot about the 2.7 stroker but i can never really get enough info on it, because everytime i search every1 always post things and say "I thiNK"

anyways what other options do i have without doing a motorswap?

and do you think it would be stupid to swap the 3.73 for a 4.10? the car is mainly gonna be used for auto xs? so gas milege wouldnt be a factor.

2.7 stroker? u already have a 2.7...

2.7 stroker? u already have a 2.7...

yea, but a low revving, low hp/high tq 2.7.

You can get a chip, a lot of people here really like them, and they actually do help out a bit.

No he can't. '88 super eta's don't have any aftermarket chips that I'm aware of, at least not JC, Dinan, etc. Unless MarkD makes one that I'm not aware of...

I'm surprised you even think a 3.73 is liveable in an eta. 4.10 would be ridiculous. It's too much for most people with M20B25s - and those actually have a useful 4-6K rev range.

Performance wise, there's not much worth doing to your motor. At least nothing cheap like bolt ons.

Want it to go faster? Make is lighter.

Damn, didnt know that about the super eta's.

learn something new every day

From what I know, no one makes a chip for the super-eta, at least I know JimC doesn't.

The great thing about the super-eta is that it has the luxury of being able to transform into an uber-M20 for very cheap, and quite easily, since it already has a 325i head. Ditch the single valve springs for the 325i's dual springs, replace the cam with the 325i's (or a higher-performance one). After that, add the 325i's entire intake and fuel delivery system, meaning the manifold, throttle body, and injectors, as well as Motronic 1.3 from a late model 325i and biggety-bam, you've got above and beyond 325i hp and torque for dirt cheap.

At least in the case of Jim Conforti's work, only being available for 1 model year made the super eta not worth the developement costs of a completely different chip.

[bimmer8604]

That kinda sucks about not being able to get a chip.

Sounds like you should just do the motor work and have fun with it.

I guess they had made one for it for testing, but because of the Frankenstein configuration of the super-eta motor, the gains it produced weren't worth the cost of further development. But you're right as well, there weren't enough of them made to begin with, let alone enough of them owned by enthusiasts that would buy a chip for them.

by doing what u said above, would that also raise my redline from 5300 to 6700? like the 325is? so

[SpecM]

-The valvesprings themselves won't raise the redline, you need the 173 computer to do that. The 2x valvespring just raise the redline POTENTIAL of the motor.
-Why did you add an 'i' exhaust? Dude, we already have that!

-Yep, b25i cam + valvsprings + delivery setup (TB, Int Manf, injecters (or use m50/Ford units)) from an 87-91 325i, is, ic, ix, whatever. Should be cheap as those are factory pieces and PLENTY are lying around.

-SUPER ETA FTW :twisted: !

[ehlpitel]

This thread makes the super-eta pretty desirable for building a stroker! What are some specs on a built up stroker in terms of RWHP/RWT? I mean with a eta bottom emd, and i everything else, maybe go a little further with more aggresive cams...what have some of you guys dynoed?

[nando]

if you just did a basic "stroker" with a stock i cam and ecu, it won't be like 200hp or anything, but it will still be pretty decent (and a big improvement from stock). of course it's not something you can really guess at, it would really have to be dynoed.

[SpecM]

-Remember, a properly converted 2.7i super-eta will have an extre 200cc's worth of torque BUT slightly lower compression (8.5:1 VS 8.8:1) SO it's a toss-up... ;)

well when i got the car the muffler was rotted out.....and the muffler only had a single tip then i took the whole exhaust sytem off a 92 325i vert and put it on mine.....I think im ognna go to my local muffler shop and have them make me some kind of track pipe soon....

after that im gonna start re-doing my suspension as the car will mainly be used for Auto-xs

and i havnt dynoed the car as of yet? but when i ran my car at the 1/8th mile track i ran a 9.6 as my best time...and a constant 9.8 or so

and i have also raced a a few e36 M3s and stayed right next to them till about 55mph then they start pulling, or sometimes i even get the jump on them from the launch.

heres some pics of "the beast"





btw yes super eta ftw!
