You've got me confused with Mike or Obnox, Greg. I've got fuel problems at 4 psi! I'm now pretty sure my VAF is bad, however, so hopefully the MAF conversion next week will correct the problem. Then I ought to be able to drop in the high flow injectors and get 7-8 psi of boost out of it. Obnox is the one with the stroked 626, and he's running around 10 psi of boost making about 340 hp... and he's also not happy with how it runs.
Gene/=/Splicer: anything is not possible. There is this little thing called physics that will get in your way. Civics typically run low compression pistons to achieve high boost levels -- the KLZE has a higher compression ratio than the KL03, so you're going in the wrong direction. Civics also have a simple log-style manifold with only 4 cylinders so they can use throttle body injectors without worring too much about fuel distribution among the cylinders. High powered Civics also tend to replace the engine management and run high flow low impedance injectors (which they can get for their engines).
I have talked to Thomas, and so have many others. He is an excellent salesman, but many people have had issues with his kits and advice. He has built up some many KL03s but the ones making 15psi and greater than 300 hp have had MAJOR surgery and usually run race gas (or at least 94 octane). Don't expect to plunk down $4K and drive away with a nicely refined 350hp MX-6 -- it won't happen. You'll have a finiky cantakerous beast with a tendancy to blow itself up or at least soak up your paycheck.
I don't have anything against this forum, but you should wander over to the Forced Induction forum at ProbeTalk -- there seems to be a much larger collection of boosted KL03 owners over there, and there is a huge archive of very informative threads waiting for your perusal.
