I was wondering that could some of these engines fit straight (or with little work) to 325i E30 gearbox:

1. M30B30 from 730i/530i
2. M106 from 735i
3. M88/3 from M635i
4. S14B23 from M3
5. S14B25 from M3 evo3
6. S38B36 from M5

How hard it would be to make these engines fit? Electrics and mounts aren't a problem to me, but how about the fitting to the gearbox?


And thanks for the help already

this has nothing personal to do w/bmw or any other car.

the drivetrain is the easiest connection to fit.

but you need to measure it correctly. and then
take the peiced to a machine shop, they will form one peice from the two, if indeed they are different.

my friend did this back in the 80's with a 81Mazda truck and a 88 engine, he said the electric brains were the most time consuming, but we overrode them .

have fun storming the castle: _billy crystal-
take pics.

I was thinking about mathching to 325ix gearbox and keeping it 4wd. If anyone has pictures about the gearboxes of these engines (and 325ix's) I would like to see them and think which engine would fit with little working

i should ask my friend, who inciedentally owns a "ix" and they differ in a number of places.
the ix is very hard to find, he found one with less than 60,000 miles and its really great, takes it up to the mountains every weekend. drives hard too, and he used to own a talon (turbo-4x (whatever that model was))and drove that to the ground. but it still worked.
if you need a new motor,
why not go the distance and get a MOPAR small block or something amazing.

the e30's are amazing but lack raw power.
mines going on 200,000 and the whole car seems new, and everything is nice.
ive known these cars to last over 300k/ and still run great.

ill call him today and find out if its the tranny that does all the 4x stuff or if the motor is different from mine.
we never compared directly, we drove each others and mines definately faster.
but his came w/better ground effects, rides higher, had the ski-bag, etc.
mine has retractable rear windows, epsiloids, ricarro seats, lower too.
