Re: Inline 250 - T3 Turbo - w/ Video

I got around to tuning it a little. I also put a magnaflow performance muffler on it with 3" and it turns out flush, right in front of the rear tire. It sounds deeper and not as much turbo whistle, but it still sings under driving boost. I re-jetted it down to 66 jets with a 4.5 pv. It seems to be running leaner and better ( I think I was running really fat earlier ) I will try to post a new video with the new exhaust.

Ghostwhite - go for it. It is important to get the right turbo, plumb it right, get a good condition used 350cfm Holley 2 bbl and make it blow thru. All else is exhaust routing. If you have any questions, ask me. I'll walk you through it. I've got pics documenting the whole procedure.
