A friend of mine has a brandon new T3 Turbo wich i was told is perfect for my size engine, does anyone know of a company that can make or has a setup without the turbo? need blow off valve, wastegate, all that stuff, down pipe, i only got the turbo, thanks.

 

It is a T3, it is most likely to small. Do you have the compressor trim and exhaust a/r?
If it is a 45 trim compressor then no, 41 trim compressor hell no.
Even the largest configurtions of the T3 are on the under size side for the 3800.
The turbo calculator is saying a 50 trim would be best but in real world appictions it is a little on the small side. But it dosen't say what to use for a exhaust housing. The guys useing turbo on the 3800 over on camarov6.com like some kind of T3/T4 set up.
Becarefull what you say over there on that FI bord they tend to flame, a lot.
