I've been doing some research and I've found that a few turbos from some diesel trucks will work well as an upgrade on my 93 Mazda Rx7 Twin Turbo. I'm pushing about 400 hp now and I'm looking to go to the next step. I need something in the range of .60 A/R compressor and 1.00 exhaust. Also what sort of flanges do these turbos have? I really appreciate any help you guys can give me as I know I'm not one of the guys but I hope to be in a few months when I get a new truck to tow my baby with

 

cant give you much info about the diesel turbos...put do you know anyone that wants a 1995 rx7 with a 20B ?
