E36 performance question - BMW Forum

hhgreasemonkey · 02-04-2009, 02:07 PM

hey, so i've got a 1992 325i. its my first car so i can't really complain but unfortunately, its a 4 speed automatic

i have a lot of ideas i wanna do to the engine but does anybody know how much power my transmission can support without it failing on me?

& while i'm on this subj. does anybody know any cheap transmission alternatives? like upgrading the auto? or switching to manual? and their cost estimates?

Its good to at least 250 ftlbs or so, plenty of dinan S3 e36's out there still and those push ~240 ftlbs out.

so do you think if i bought a greddy emanage and had it tuned my tranny would be fine? cuz i was informed by one of greddy's employees that my car would be pushing out around 340hp or so

greddy makes a turbo kit for e36's? N/A you won't make that much from an M50.

oh well greddy sent me a follow up e-mail stating that the greddy emanage won't work on bmw's because bmw ECU's are "too smart" and when the piggyback management system makes changes the ECU will self correct itself.

haha bummer

Negative. the BMW DME(ecu) can be modified to not make corrections to achieve an air/fuel ratio close to the stoichiometric air/fuel ratio. seen it on an autoX car i ran into last year in San Diego. but in order for the catalytic converter to work at maximum efficiency the vehice needs open and closed loop. plus there are easier, cheaper ways to manage the engine than making a piggyback work for the BMWs DME.

Garbone,

I was under the impression that most reputable conversions include the DME updates or piggy backs to make it work. Reason they are expensive.. hardware plus software and making sure it wont break!

And if ford can make a 2litre 4 cylinder output 550bhp.. i'm sure there is no reason why a fully worked 325 couldn't go beyond that with ease!

But in answer to the original question.. how much money do you want to spend.. coz power costs! And yeah.. have you ever driving a vehicle that has over 300hp?? It takes experience to drive them at the limit without screwing up big time!
