Gearboxes?

[HMC]

Are the 316 and 318 manual boxes the same?

Yes,and the galvanised 318iS uses the same 'box.
320i uses the same insides in a slightly different case. 'Box is the Getrang 240.

Thank you very much.
The search beggins.

Only if you are taling about m40 engines

316i/318i fine. No idea about 318is. Doubt the 316 will work. 320i wont fit.

318iS (M42 engine) gearbox is different to the 316i/318i gearbox. It will bolt up to the M40 engine, but you might need the 318iS prop (I dont know if there are differences between the 318i and iS props).

[HMC]

Yes its for for an m40 engine, mines an auto so am just gonna buy a whole car to convert and keep all the extra bits as I will no doubt need them for when I crash (allot)

m42 box has slightly different ratios no?

[jmc330i]

^ Slightly different ratios AFAIK, but also a slightly different shaped bell housing compared to the M40 box.

I will try and get a photo next week, when Ive got both to compare.

Am i right in thinking that a 320i gearbox is the same as a sport one ?

I've read that is true if connected up to a 325i

I have read that it has the same ratio's but is a bit weaker, time will tell on that one

I also have a unknown Bmw gearbox. it was removed from a kreg 318 touring.
Was mated to an open 4,10 diff, which made the engine very buzzy and wanting another gear
even when in 5TH. Never did find out what model it came from

Ratios are very similar.325i uses Getrang 260,which is slightly larger in every respect.(bigger bearings,bigger case)This is why the 325 has a slightly shorter propshaft.
I have used an ex 320i 'box/clutch for more than three years now with my 2.7 with no issues at all.
Remember that the 325i is improved over 320/323 in lots of detail chassis items,rear brakes,front struts are other bits that spring to mind.
