I would strongly advise you to stay around 6-8 psi on a B20. I see you have some studs for the head, but its the walls that crack on the block on the B20's. GL.

 

 

depends on the setup but it should be good to around there. On my 2.0 A20 the .60/.63 worked good, fully boosted by 4k, big top end etc

 

yeah its been ------- 4 months and he still is making excuses...basically i got owned...

 

Yeah I feel you, i got owned too

 

Log mani with 3" Down pipe, running 9psi and boost on the b20 starts at 3 and full boost is in right below 4k rpm. Sick setup surprises alot of unsuspecting individuals. this is with the t3/t4 60 trim. Garrett

 

I'm assuming that's with a 0.63 A/R on the turbine?

 

I have a different engine, but it's the same displacement, it's a 2.0L. I now run a mitsu hybrid 50trim, but i used to run a full garrett t3/t04e 50 trim compressor wheel with a stage 3 .63AR exhaust. I'd hit full spool right around the 4k range up until redline at 7k. I wouldn't consider it too laggy in my book. Great street/strip turbo in my opinion.
