My 1st post.........hats off to snowman.......just read all 18 pages. Nice to see a bunch of good experienced people eventually set their egos aside for the good of the thread..........I've been playing with twin turboed dmaxes for about ten years. Threw away enough money to buy Miami just black smoked it away. I have a 66 c10 I'm determined to turbocharge.......6/8 psi.....more for the novelty than performance. Lots of good info here thank you all. Got a Clifford intake and a spa exhaust and a big time diesel builder build me a fast spool big whistle. T4 I think. Scored the intake and the holly on eBay today it's already setup to push thru and basically new.........gonna have lots of questions.......?Just couldn't bring my self to do a v8........ Prolly would save some money......I just have to be different.
