So Far Have This In Mind For The Set-Up

Type-R head
Skunk2 pro series
full valve train
70 mm throttlebody
Race Header 4-1
3 angle valve Job
Stock b20 Block want to run the pro serious 3 hope the bottem end will hold up

b16 tranny
welded diff
CM clutch Kit
stage 2 driveshafts axle systems
Still researching some parts for the build

 

A stock B20Z block with the PHK pistons even with the dremmeled out valve reliefs for bigger valve to piston clearence still will not create enough compression to run these cams to the full potential, You'd have better results with pro 1's IMO. But either way GL!

 

get the valve reliefs cut and have the head milled .050....but after that money spent on machine work you could have spent a little more and bought pistons.
