E46 M3 custom Turbo build

[Mattn1192]

I always said I was going to stay NA when I got this car & will never go S/C or Turbo. But here we are. Welcome to my Turbo build.. I’m not looking for an insane amount of power, just a “bit” more. Shooting for 450-500whp. All maintenance has been taken care of on the car & it’s in great condition. So far for my build I’ve bought: 550cc injectors by Bosch, Mishimoto Intercooler, Walbro 450LPH Fuel Pump, meth-kit, and I’ll be purchasing my buddies turbo (Borg Warner S364.5 SX-E 8776 64.5/68) soon. Fabrication will be done by a local shop. Still have a bunch of things to buy, but I’ll make sure to update this post as frequent as possible.

I’m very open to advice and recommendations (I’m going to need it). I’m looking to have a top mounted turbo instead of a bottom mount turbo setup. What direction do you guys think I should go in as far as intake manifold and exhaust manifold brands? And what are your experiences with them?

Lastly, Hassan will be the one tuning my car. Stock ECU/DME.

Hey man any updates with this?

I’d highly recommend using ID1050x injectors, you’ll have those 550cc injectors tapped out quickly with that s364.5 SXE
