slap on a GT30R .76 AR, you don't need low end, you need top end.

new cams.

you're going to have to find the best tuner in the world to get this to run at all.

probably some 600cc injectors too, external fuel pump wouldn't be a bad idea.

2 more built 1nzFE's for the first time you over boost the turbo and can't provide enough fuel (most likely the 3rd or 4th dyno pull).

how much do you forsee this costing you? you pretend $$ isn't a factor, but once you figure out how much you're potentially going to dump into this car you may choose another route.

my guess is around $30k to get it to the point of reliability and more than 250whp use able and safe.

i consider this the collecting information process. thats why i listed the vital items first to gauge the cost. if it's not an astronimical amount after i figure that stuff out i'll move on to the fuel system. sleeving the block will key to figuring out how much boost i will push, i want between 20 and 25 since that's what brash boys said will get you over 300hp going twin charged.

there is a guy who lives less than 2 miles from my home who has a shop literally next to his house with every piece of machinery imaginable for building engines. its all he does for a living is build big block chevy engines. and my dad has known him forever so i'm sure he wont break my back in fees. and he does amazing work for being the crazy mf he is.

so you tell me, at 22.5 pounds of boost what compression pistons should i use?
