There are many opinions on who's is the best. Anybody have any experience?

If you live in the USA, check out cbperformance. Otherwise go custom....

How does this sound?? IDA, machined to 52mm, Modified garritt T03, 8:1 Cr and 0.9 Bar (13psi) boost. Should be fun on a street car

Webers should be used between the turbo and atmosphere as they are harder to modify to "blow thru" than a dellorto.
