this is my setup

I would like something less lag
but plug and play on my manifold / downpipe
pro1 cams are too aggressive with a turbo of that size?

 

There's some info in the b16 turbo builds thread. One guy said he hit 20 Psi around 5200-5400 rpm. And if I remember correctly you want a 61 lbs/min turbo or larger for pro 1s. I think the 5858 is below that.

 

I saw 20 psi right around 5200-5400rpms. Its a great street turbo. The powerband is amazing! Im pretty sure it flows right around 60lbs/min. I would think some dialed in pro1s would work nicely. I have itr cams and we adjusted them just a tad. Could of prolly dialed them in a little bit more but decided not to.

 

Yup your setup is the one I was talking about. And also sorry the 5857 thread has the mosot info on the 5858.
