M42 supercharged build!

[AdOz]

I am currently building a 2002 with an m42 and an eaton m62 charger.

I picked up the engine from a 318is and the charger from a mercedes.

I'm currently building an inlet plenum to bolt to the split manifold! I was so glad to see that the manifold split in to two parts! I'll post photos of this when it's complete.

I'm looking for some advice on what people have used on boosted m42s. I'm aiming for high 200s-300 hopefully. So basically I'm curious to what injectors people use? What would a good clutch be to use?

I am also curious to diff gearing I was thinking 3.46 from a 325i? But I would appreciate advice on what others have used must be LSD

I'd imagine an m20 clutch would be up to the job along with an m20 flywheel and starter

What are you going to use for engine management Ill be keeping an eye on this thread being looking at the m62 myself for mine or else the mini m45

I've seen a few applications using the m45 bolted straight onto a plenum making 200hp roughly cheap way of doing it with a fair result but a twin screw charger kicks out serious heat so intake charge pressure sky high!

I'm aiming to make a bracket and run through an intercooler into my own plenum.

I was looking at the new aem management the ecu is designed for 4cyl only which brings the price to around £600

Started on the intake manifold today it's been in the steam cleaner 3 times internally the fuel and dirt was not looking good I think I will rebuild the top end of the motor too! Progress to come soon!
