what is the a/r ratio on the t-3 garrets you are talking about. the price i found on the new garrets was 549$ each, which isnt bad, but if i can dig some up in a junkyard and rebuild them for much less, that saves tons of money. i am building this kit for the street, and for stock mn12's. me and a friend have done a race setup for his 03' cavalier and are getting started on mine with research. we may try to market our kits for sale, but have to see if there's a market. anyone interested? anyway, check out the dsm ( mitsubishi ) intercoolers off the eclipses, they are side mounted and may be perfect for our cars since they are small, for twins you can have one for each side of the engine. i have a couple rough sketches of my turbo plans but whew, the piping is a mess. i want to ry to hide everything under the car or behind the engie. i might be able to if i get creative enough, the intercooler/s is the hard part. is it possible to swap to a center inlet throttle body. i have seen some but i htink they are for the 5.0? would make life easier to plumb the system past the intercoolers. this is a real PITA no matter which way you go!
