E30 Zone

Ok then peeps, need to ask you for your expertise,

I want to have a go at a M10 turbo conversion, i have 318i M40.

So what do i need can anybody be kind enough to list me the parts?

Also where would i get a turbo from? would it have to be off another make and model of car?? which ones fit?

Was going to go for 2.5ltr V6 or a V8 but i miss having my turbo punto GT, so now want one in my beemer

Thanks for your time, Matt

you need this manifold to start!!

plus i have a turbo set up for sale which will prety much fit any e30

To start with you'll need to ditch the m40 engine if you want to do an m10 turbo project.

A manifold as Kos said, possibly off a 2002 turbo, or an adapter.
A turbo T3 i would think, maybe a cossie one
Megasquirt
FMIC(possibly off a volvo)
Mandrel bent exhaust and charge pipes
Lamba sensor and boss for megasquirt

And some decent brakes

the manifold picured if for an m10, youn can get them for an m40 i belive.
you could use a piggy back ecu if you wanted

You have the wrong car to start with...

M10 engines are only in pre 88 cars, if you have a m40 engined car its later than this. The main engine wiring si different in these cars and apperently very different, you have to change pretty much everything.

You can turbo cahrge your m40 but it will cost loads and you will never get any good gains, far better to ditch it and start with a m20 or m20 6 cyclinder engine.

If you get a m10 engined car things are more simple, but the manifold pictured above I think may only be sutible for LHD cars.

I have only ever seen one RHD turbo m10 and the whole engine had been twisted in order for the manifold/turbo to fit.

yes but he is planning a swop by the looks of it

it will fit RHD, i have spoken to the manufacturers about it

now thats taking it too far, any one skilled with a welder doesn not have to go to these extreames

im planning on ditching the M40 for an M10 just to let you know my cars 1987 on a e-plate and has a M40 engine, must be one of the first??

yeah will to give it a go, but it wont be a cheque book project!

on-going as and when money and time allow!

just looking for someone to point me in the right direction maybe with some help on where to find some cheap parts or alternatives?

And some sort order on which to do things and description on doing the M10 turbo conversion hopefully with pics???

Could i get any parts from a ford sierra cosworth to aid in my conversion?

Turbo
intercooler
propshafts
boostpipes
etc etc etc etc??

any other i may of missed off??

Cheers Matt

IIRC, some turbos and other bits left over from the Brabham-BMW F1 days were sold off somewhere recently. 1200 HP !!!

Hi

Alot of 2s & e21 are turboed f you google you will find. pro turbo in finland still make manifolds, 02 turbo manifolds rare & expensive, until last year there was a m10 turbo racecar making 350 now an s14 turbo making more. there were a lot of aftermarket turbo kit sinthe states with turn up on ebay.com from time to time.

you want an 02 r s14 crank as they are forged.

Im planing to put a turbo on 1.6 engine. I know i can get more power from other engines (i have M50 in my driftcar at the moment), but just got another E30 with M10 1.6 engine and i want to make this my longterm project.

How much power can stock pistons take ? Ill probably want alot of boost, so ill probably need forged pistons right ? Does s14 or 2002 crank fit to 1.6 engine ?

What do you guys with turbo M10 do with head and air intake / fueling ? I would like to go oldschool with carbs or maybe some sort of ITBs. Any sugestions ?
