back to basics
Well I have been looking for a good detailed article on picking the correct turbo. I am not an expert by any means, and would like to upgrade my turbo.
thanks to anyone that can actually help.
this is what I have currently.
408 forged 9-1 cr
ported heads with studs
cam 234/238 595/609 lift @50 114 lobe separation
stage 5 4l60e by RPM ( hopefully it last till I can get the rossler 4l80e w/brake)
TCI 3500 convertor
factory rear with 3:23 gears ( s-60 with 3.54 gears on order)
dual 340 fuel pumps 60lb injectors
gt45 76mm turbo .66/1.05 ar (needs new seals)
the turbo was rear mounted when I bought the car. It had a factory style shortblock (346ci). The car was great for roll racing, but since thats illegal not the best set-up for me. I will drive this car around town, to work, and maybe a trip or two. The number one purpose is drag racing though.

Sorry it took so long to get back. Well, since you have a 408, you could get away with a 76mm turbo but a 88mm will be the best. I get mine from Precision. Good units and very reliable. As far as a tuner goes, check out Frost on here.....he can get you in the ball park.

Frost if you are not more than 2 states away its not out of the question to have you do it.
