Default What turbo size and intercooler size?

I am currently going with a 408 iron block. AFR225's out of the box. not sure on the cam yet. Fast 90mm intake and Nick Williams 90mm TB. what size turbo would be most efficient for this setup. of course I want boost right away. but I understand that with turbo's they need to spool up. also what size intercooler would be best for me. I want to keep the front bumper support. I have a person that will build me a new support out of chromemoly if I decide to go that route. I basically dont want to run into somthing and then total the car. I want the car to still be safe while making crazy sick hp and tq. lets say a goal of anywhere from 700rwhp to 1000rwhp. I know this is a big gap. but I want to be able to have an electronic boost controller and turn the boost up and down at anytime. thanks in advance.

so would going with something like what the sponsors are offering be good. like a single GMRspeed turbo kit with a turbo upgrade to the 76? or going out and using the 6ltr manifolds. and building it that way. o yeah and I want to keep AC. haha

At least a 88.... your going to choke the 76 out way early with a 408. you wont reach your peak HP goal of 1000 if ya do.

Keeping the AC and making that power is going to be a challange.
Good luck and dont forget the fuel system and drivetrain.

Will an 88 or 91 fit without cutting the front brace/radiator support?

Call Jose, he can tell you what you need. I would suggest at least a PT88.
