Bought a built NA motor that I'm dropping into my Prelude and it currently has Pro1 cams. I read on Evans-tuning's site that they might be a bit big unless you're running a large turbine housing. I have a Precision 3431e, .63 A/R exhaust. full 3" exhaust, shooting for 400+whp. SFP tubular manifold. Would that cause too much exhaust backpressure before the turbo with a cam that large?

 

those cams are for 61lb/min+ turbos...
way too big for your application

 

exactly what I needed to know, thanks! The motor was a high comp nitrous build, I figured I'd need to swap them out. Looks like I need to find someone to trade for some tuner1's
