If you're going to drop in a 325i motor, then attach it to a Getrag 260 trans and either a 3.73 or 4.10 diff (the latter for better acceleration). Didn't you UK folks get a "sport" gearbox....something with closer ratios? Or was that just the M3?

i aint sure if they do a sport gearbox ?

what will i need to change or would it be easier to change something else like diff or lighten the flywheel ?
cheers

BMW europe has an def. a sportgearbox in its E30 program
called dogleg tranny (i tought it is an Getrag 245/6 or something) with the first gear underside lef and the 5th gear is 1:1 :P

You'll need (basicly) :
the M20b25 engine,
wiring harness,
325i ECU
Getrag 260 gearbox (or the sports one)
Driveshaft
Big case diff.


and def. change to rear disc brakes you'll need them


btw: maybe you should talk to some M50 guys here on the board if you want bigger power :twisted:

[mikeedler]

you need alot more than that, and the small case diff is fine for quite a while-- its probably a 4.10 at that too.
radiator
hoses
airbox
basically everything under the hood along with driveshaft, exhaust, and like said pef. brakes

[bobmaf]

what i would like to know is the wiring loom needs changing but which part the whole thing from rear lights to horn ???
cheers
bob

everything from your connector C101 to your engine and ECU

correct me if i'm wrong

EDIT: and the wiring diagram from the connector wich stays in the car needs also some
modifications ( they don't line up correctly )

Unles you already have the m20 engine go with a m50 or better yet s50.
