So now after I drove car and felt that engine power was too week for my new brakes and suspension . (oh and I smashed sump over bump last week ) . I desided to boost it cause it is cheapest power for the money.
There is my exhaust manifold I got it from e-bay yesterday. Looks prity good job. Turbo charger what I’ll use is T3/TO4E A/R-50. I’ve to weld pipe from manifold to external 38mm wastegate.

Plan is to get front mount IC, bigger radiator, electric fan, bigger fuel pump, injectors etc.
I really want to use Megasquirt cause it is DIY. Or there is some better and not very expensive options for ECU? Is there any one who have some experience with similar setup?
How much boost will take stock bottom end? Or it is safer to lower the compression (with thicker MLS gasket and arp bolts)? Where I can found metal head gasket if there is some on market?
How about engine heads do they give trouble?
I this is my first boosted BMW so I’ll appreciate for any help.
Thanks

Sweet
 

That looks awesome, man. Good Job!

What ever you do make sure your effective compression ratio stays at or below 12.5:1 and run 91 octane or nothing will keep the thing together. There are kits to do what your attempting out there complete with bar and plate inter coolers and plumbing. Get a turbo timer, follow the directions and be prepared to spend some bucks on tuning to get it right and reliable. Cheapest thing you can actually do is a dry NOS system with the nessecary upgrades. It only works when you need it and doesn't hog premium gas like its going out of style.
