How much HP can I expect to get out of a Drag or Rev-Hard kit?
I have a fully built H22A1 running ~9.5:1. I want 500+WHP and I am told that this can be accomplished with the Drag kit w/upgraded ball bearing turbo and upgraded wastegate. I hear the Drag manifold sucks, but no one explains why. What makes the Rev-hard better? Can either one of these kits produce 25+PSI on my H22? Would I do better just to assemble a setup from scratch? If so, who makes the best turbo manifold for a H22?

for 500+HP, i'd go with the REV HARD upgraded kit.
The drag is good but not that good for 500+HP.

The block is being sent to GEM to be fitted with godzilla sleeves. The head is going to EnDyn for the complete head package. I am rebuilding my transmission and installing a Quaife LSD, I already have DSS Stage 2 axles. I have ordered Hondata S200, already have an AVC-R, MSD6AL, and RC 1100's

The reason rev hard manifolds make power is because of the thick pluming pipe they use . It holds in the heat . this means less energy is lost due to heat dissipation and more energy is used to turn the turbo . the drag manifold is cast and not as thick . Both do not flow that great . Try the South Florda Performance kit their manifolds(and kits ) are the best on the market . with his manifold my good friend made 571.4 whp and 391.6 torque at 22 psi and 7500 rpm in salt lake city at about 7000(i think) feet above sea level un corected and half tunned SFP's # 305-233-8520 P.s. ask for Frank and dont tell him your golf handicap he won't be impressed , pimptown boy ..... he he... late !

SFP is a POS..!! it is mig welded and will crack faster in time...PRODRIVE is a POS also ..!! I have seen there axles and Spools shatter like glass...!!cant hold any power..!!!We can all talk bad of peoples products like lil kids.. words do get around ...dont put down other people products if yours arent perfect either..!!!
