Anyone have good knowledge of the drivetrain layouts of the M's?

Wondering about dropping a M5 block (not the new shape engine) into the older M3(E36).

Possible?

Raks

yeh, but dont like the idea of ruining the engine like that. would get more money to just trade the blocks, no?

bobfrog1

It depends, if an m5 engine drops straight into an m3 shell then I'd go for that but if there's a lot of work i.e. engine/gearbox mounts, wiring loom etc then I'd leave the m3 engine in and "play" with that, running 8psi on a big engine wouldnt be that much, using low compression pistons would ensure this but there seem to be a few people/companies that are doing these conversion, its worth a look around

M3 Evo

Raks - i wouldnt bother, whats the point of all that effort just for an extra 19bhp, and i'd imagine it would cost ££££££s

Why not just tune it thew M3:

Gruppe M induction kit £800 gets 15bhp
Bexley unichip remapping gets 17bhp £500
Supersprint decat and exaust worth around 15bhp - 1K

Get this lot and you will have a seriously fast M3 (good enough to take on a 360 etc) and save a bundle over an engine transplant!

Raks

wow, didnt realise how flexible the M3 is!

could buy a baseline M3 then (coupe) for about £12-13k and then throw in a couple of k for tuning, and it would a nice luxurious rocket.

Hmmmmmm.......

hey, could the M suspension cope? Or would it need a revamp also?

M3 a Q car ?

most things dont get a look in against a standard one so hows that a Q car ?

Raks

Read the posts above

M3 Evo

I'd say the M susp is up to the job of around 380bhp.

Prob reccomend eibach kit or ACS first though...

Raks

Would the de-cat render the MOT invalid? What about a sports cat. Is there one available for the 3 series? Same amount of power upgrade?

Also, would the car benefit from the 'other' types of upgrades? Bigger injectors, lightened flywheel/clutch, lighter pistons/crankshafts/cams, ported heads?

Really thinking about an upgraded M3 as a daily drive. Think it would be undriveable as a daily?

yes it will fail MOT without cat (meow) but MOT it first then it will be good for a year. you can put i back on next MOT. i've de-cated my J91 E36 325 and that will be okay cos dont need a CAT until 08/1993 k reg. sounds great too just a little louder and deeper. (scorpion bypass pipe)

I would rather not have the problem of switching pipes for the MOT, be it only once a year. Sports cats not possible?

Round where I am, the cops are very cautious with drivers as it is, so I don't want to be pulled to then be questioned about the exhaust etc.

Ive been in the car when they have done this, not only is it a pain to go to the station later on in the week with documentation, but it takes 2hrs out of the day!!!
