Hey guys need little help about a wastegate.
I have a BMW e30 with M20B28/ made the B27 a bit bigger/ and the tubo that im using is Garrett TB 3402. The car will be driven at 1 bar pressure. So the question is what wastegate should i use and do you have any idea if Demon wastgates are good??? / I have about 150 pounds to spare for this/
Ty in advance
