Turbo Ideas
 

hey i have a 2002 Chevy blazer xtreme with the 4.3 whats the best turbo kit out there for them? any help appreciated

I would suggest looking for either a remotely mounted rear turbo, or a smaller turbo for in the engine compartment.... although I do not know where to point you.. You might wanna look at a vortech supercharger, as I believe there is a kit made for the 4.3 in the blazers

Check out STS or Steins turbo systems. they dont make an s series kit, but they have a universal for around 1600. but only expect about 300 or so RWHP. I recommend doing a 5.3 ls1 swap.

$3600, but includes every nut and bolt needed. How much custom fabrication are you willing/able to make? That'll determine many things. Also budget. I'd like to second the notion of a LS based engine swap.
