CAMS !!!!!! V. Springs !!!!!!!!!! Log manifolds kill tq everywhere. Really look into a tubular.. like Hybrid Dynamics or Full Race. I have tuned a lot of cars and can tell you that they kill about 15-25 % of your power at identical boost levels. Douche Works like tim said.. thumbs down. 550's get a KA to about 380 rwhp getting close to max. I run 740's on the Bandit @ 22 psi w/o any problems. One real big thing I have noticed about KA's Jonas... they like to lift the head... get the updated ARP head studs.. I don't think the old ones are even sold anymore, but make sure you pick up a good set. We usually stock them, because the Bandit chews through headgaskets pretty quickly. You can get a built KA to 450-500 fairly reliably on pump gas @ about 19 psi.. but you have to do cams... have to have to have to. No cams = 80 less hp. Last time I did a stock cam / built bottom KA with a .63 35R like Tim's it struggled to crack 400 on 20psi... and that is a serious fucking turbo.
