m40 engine transplant

[soma]

Hi,

I recently bought a 316 e30 from '87 for only 400 euros, that's about 250£ with a tired engine. I have removed the engine and Ia am planning on replacing it by a M40 engine, the 1796cc variant with injection (the previous one was e 1766cc with carb), the block itself is practically the same, only 26 bhp more powerful.

As the transplant is coming closer, I'm dealing with all sorts of questions, maybe you can help me?

1) Whitch problems will I have top face regarding electronics, does implanting the electronics from the new engine succeed?

2) I'm planning on implanting the engine and gearbox as one whole, will this work and will it be necessary to change the diff as well?

3) I've noticed that there is a box with all sorts of electricity under the hood of each e30, will I have to replace that to ?

4) I'm having my doubts whether to legislate the car being a 1796cc injection, or to leave it at a 1766cc carb and hoping no one ever finds out?
WHat woul be the right thing to do and will I have to inform BMW that the chassis number and the engine number do'nt match anymore?

5) In the future I would like those old school alpina e30 rims suiting my 316 (actually a 318i in sheapsclothes). I'm wondering whether 17 inch alpinas are made and if they fit under a standard e30 shell.

I hope you guys can give me some answers to my questions. It's not that I don't know sh*t about cars or mechanics, it's just that it's so damn hard to find correct and precise info regarding these BMWs.

Thanks

Thomas

I think most people use 17" alpina replicas but they're more for show than go - 15" BBS are still a very good option for handling.
