you'll be fine with the cpr system. even if it drops a few psi at wot you'll be ok, hell mine drops to 20 psi and still made over 600 lol.

Try the stock h2e turbo with stock headgaskets and good h-11 headstuds, if the stock h2 doesnt get you where you want have it modded. Id also recommend sticking with EDM nozzles on the injectors- i think diy now uses the good edm nozzles. You might try dropping the compression a touch to help out with cp, i had about 5cc removed from the bowls of the pistons. IIRC it will drop the cr somewhere in the 16-16.5 range. Your in Tx, so id recommend making a trip up to DFW and getting some custom tuning from Wildman to get things just right. If you have any questions just shoot me a pm and i'll let you know what i think or if ive tried it.

thanks Luke, that turbo info was exactly what i was looking for. why would i need to drop the compression? i'm new to the lower compression stuff on these things. the only thing i know about it is people do it when they are using a lot of nitrous or something in those high horsepower trucks.

Dropping compression just helps keep the cylinder pressure lower when you start running alot of fuel.
