Bmw project

Hello sorry for my bad English...

I have a few questions..

My car is a BMW E30 320i With a 2,7 liter engine..

I'am working on a Turbo project with an Garret VNT

The Turbo pressure is 20 psi, which is to much..

I have bought a external wastegate from a Audi 100 turbo have a standard pressure regulator for 7,5psi. thats good..

Now my question is...

How do i use the wastegate with the VNT system..
How can i be shure that the turbo will work at full RMP..??

Help anyone..???

A friend of mine just got his 87 535IS running good and strong using a calaway turbo kit designed for the 325. Car makes alot of power with upgraded turbo and intercooler.

I thought the 2.7 I6 was BMW's ecomony motor. That has the weaker valve springs vs. 2.5 I6.


later

The car is an Bmw E30 320i from 88-

The engine is an 2,7 with 2,5 head.. and 2,5 injection..

The ration is at 8,8:1 and kan work great with 7,5 psi..

The horsepowers for the car with out turbo is 183hk at 5300rmp..

Damborg,

You might want to try this list www.unofficialbmw.com. There is a message board link from there. They have seperate lists of E30's. I would try to post to that and see if you get any good information.

I read the list for my E36 all the time. It's been a great resource.

I've hears that, thats a pretty awesome setup. About as good as you can get from the M20 engines. With a turbo it should be pretty crazy!
BTW, I think www.bimmerforums.com had a forced inducton section on it
