I too am planning to build a turbo setup. The guy who really knows his stuff on this board regarding turbo setups is Paul. See attached URL link

I'm pretty sure the stock 320i injection system can handle boost, but only up to a certain amount. A T3 should work great for the M10 engine. I think you might have problems with that compression ratio, however. Generally turbo'd engines have less compression ratio to avoid pre-ignition problems. I think stock 8:1 will get you to like 10-12 psi. Above that and you'll need lower copression. Running 7-8 boost might possibly allow for the higher copression, but I'm not sure.


I want to add a turbo to my 2002. Can I use a 320i injection system without modifications running approx 7-8 psi. If so should I use pre or post 79 320i injection.
I can fab a turbo header fairly easily and I want to use a T3 from a Mustang svo with a intercooler from a saab. I am currently using 9:1 compression pistons. Should I use flat topped pistons. Comments and advice are appreciated. Thanks
Cameron A.
