E30 M3 dogleg tranny (Getrag 265) to 318is M42

[pungky]

Hi everyone!

Is it possible to use the E30 M3 dogleg tranny (Getrag 265) to 318is M42 engine? What kind of modifications is needed if it's possible?

Thanks & regards,

Can you please post in the correct section. I'll move it to tech help...

This has nowt to do with Engine Swaps / Forced Induction

Not as far as I am aware...the bell housings are different bolt patterns (s14/m10/m30 are the same)

it does have a removable bellhousing though so might be made to work

a better option would be an e36 box ( i THINK that it would bolt straight up and work really well, 1:1 5th)

what i have on my iS is a getrag 260 box from a 325i with the bellhousing cut and rotated so it bolts up properly. works a treat but not a cheap job, and the gear linkages need cutting and welding to suit

only other way for a CR box would be the m20 dogleg, getrag 245. but the e36 box better idea IMO

wow all hale above

anyway now i have finished druling a e36 box you say do they do like a sports box for better shifting then mate >?

what e36 ?

any m43/44 gearbox will fit and work fine. The problem arises with what diff.. I think a 3.45 is needed to make any sense of it or maybe a 3.64 if you can find one

What are the gear ratios in the normal E30 318is box?

[JungleGus]

iS box is pretty similar to the M40 box, not sure if identical. overdriven 5th..usual e30 stuff nothing flash, hence the 4.1:1 final drive

same as m40 but it has syncho on reverse where m40's dont
