Mate , going Turbo is the best thing i've done. Its mental to drive, its pulls so hard with very little lag. Got peloquin difff and gemini 6 speed gear kit going in next, can't wait.

Im running full 3'' downpipe and full 3'' system with single jetex stainless back box, Its not loud. Its Really sweet full throttle It custom built by JKM in portsmouth, done a Awesome job.
Going Turbo is the best forced induction around, I had vortech V9 before with 12psi, it was quick but nothing like turbo, im using a GT3076R @ 1 bar of boost and its dam quick 401bhp & 380lbft torque
Heres a place that does a kit for 02m http://www.vr6specialist.com/tuning/tekst/prods.php?t=en∏=AV070 Was going down this road myself,now i got myself a Gemini 6 speed kit
Only problem with the turbo this way is the air filter and your turbo outlet will have to go down under the sump. its a long route back to the throttle body
