M5 transplant

[midnight]

how much of a Bas***d would it be to fit an m5 engine into an 320iSe (e30), and what kind of money would i be looking at for all the bits, and could i use the 3 series running gear or would you have to mess around trying to fit the m5 running gear

[Kos]

which M5 engine ??

3.5 286bhp

3.6 315bhp

3.8 340bhp

5.0 V8 400bhp

5.0 v10 507bhp

the first 4 have been done

the 3.5/3.6 and 3.8 are pretty much the same to do, karan a guy on this forum is just finishing his

and the V8 has been done buy a guy called glen

typo dude... 3.6 = 315bhp

All awesome engine transplants though...

i think it has to be assumed it would be one of the 6 pots and prob not the original 286bhp lump.

But reality check is that you are gonna be into between £5K-£10K before you are finished

Good luck doing it and keeping it cool.

I looked into it myself as I have a spare M5 I could have used the engine out of. Was quickly put off by people who have experience in dealing with these cars. I had a good long chat with Demlotcrew about it and was told about all of the problems.

Put a 4.4 V8 in it instead.

But reality check is that you are gonna be into between £5K-£10K before you are finished

at that sorta price, I'd be tempted to leave it in the M5 and use that!

E34 M5 is a proper fast car and can be found for £5k without too much hassle (3.6 versions)

[M5pilot]

E34 M5 is also much better Balanced than an E30 with an M5 lump in it.

You cant fit a good sized radiator and the engine bay cant flow enough air. The whole car starts getting really hot (three quarters with fans on inside and the leccy one on full chat on the rad)

Theres just not enough space.

... but there's enough room for a V8 / V12 in there... surely THAT will have even worse problems, right?

[Demlotcrew]

Very different engines, but yes they also suffer from heat problems.
But the V8 leaves space for a good sized rad.
And the V12 is a narrow bank block which leaves space
round the engine for air to pass. Im sure Dibs will tell you
how much there is to sort out with the V12 install to make it road worthy.
