I have a '99 Civic Si with a JRSC @9 psi. I love the smooth power delivery but want a lot more power. What turbo spec should I consider to deliver up to say 350 whp but keep most of the smoothness/minimize lag etc? Thanks.

ever heard of the search function?

Yes. I'm a BIG user of the search function. This time though it's not very useful and neither is your comment. I am after people's recommendations who know about the B16a and turbos 'cos I sure don't. I want much more power but without too much lag and loss of low down torque. There are a huge amount of permutations for turbo specs and would like some suggestions......that's all. Thanks.

FYI, you will need to rebuild your engine for that kinda power, resleeves, piston etc.. if you haven't already

I was wondering, what's the max pulley you can run with JRSC? I asked that becoz' I wanna know if you can make 350 without going turbo (with other parts cams, valve job)...

people always looks at how big a turbo they should run to make what kinda power.. I have to agree it is probably the easiest calculation. But what about a mid size turbo like T3, and then with turbo cams @ 13psi?... then you will have less lag and still be able to archieve the same result.

Alot of pple have been saying cams are a waste of money, I dont really agree. I am running a set of cams myself, then I will be able to determine what kinda difference do it make.
