With the 2.5 M50 engine, a .63AR will be full boost by 3500. Not sure what that .80AR will do for you. Also, youll need a chip and injectors. You can use mustang injectors, thats what im using. PM me if you need any help. Ive been thru this already.

PS. Your making the manifold? send me pics

Re:Turbo Bmw 325i
 

'86-95 GT injectors - 24# or 30# will work great for turbo

Since the charm of BMWs is the handling, I doubt this car is going to see alot of straight line action. Or at least I wouldn't reccomend it. While .80 a/r would be fine for a drag car i'd reccomend .63 a/r for a road car; my friend has a t3/t4 .63 a/r on his 2.5 liter Impreza. It's only a 4 cylinder though. It spools very quickly. I too am interested to see how this turns out. Mostly the fuel management. Those things have sensors everywhere. :P

I think my friend Josh is doing this same thing right now. I will see if I can get him on here. :)

yea my friendly is definetly not into going straight and he takes full use of the suspension so well use the .63, that is if he coughs up the money otherwise goin to scavenge the junkyard haha
