This site is 2 catalog my DIY turbo build on my 2002 4.3L 4l60e LS blazer. I started out with a bit of nitrous which was fun and all. on a 100shot i ran a best of 9.29 @ 77mph in the 1/8th. I have just grown tired of refilling bottles and in the long run it was costing me alot more. So i decided 2 go with the boost option.

My set-up revolves around the idea of the STS turbo kit (http://www.ststurbo.com/). Their set-up is a remote mount or rear mounted turbo. You can read the details on their site. There is a turbo kit out for my truck from machperformance.com but with $6,000 price tag and me being a highschool student it isnt a wise decision. And since i can peice a rearmount turbo kit together for much cheaper than an STS universal kit that is what i plan on doing.

The sts kit does have a couple short commings such as missing a BOV (blow off valve), and fueling, as well as an intercooler which my not be necessary in some applications but i chose to add one to my kit.

The Fuel system for my truck is a total mess on the part of GM. Now i recognize they didnt design or plan on any modifications be done to a blazer / s10 or any vehicle with the vortec series of motors so they went with what ever was most cost effective or whatever at the time of production. But the use of poppet style injectors leaves us without many options besides custom MPFI (multi port fuel injection) set-ups, or the use of an FMU (Fuel managment unit) and an inline fuel pump. I chose the cheaper/easier route due to funding.

Another limitation is the stock intake manifold but i wont be trying to fix that problem anytime soon due to money but eventually it will be a multiport fuel injection set-up.

The goal of this project is to make 350whp + on my truck. This will of course not be the daily tune but i want 2 be capable of this whp when needed @ the track. Along with the turbo project i will be installing a 3000stall torque converter/tranny cooler, and ford 8.8" rearend so i can run slicks without have to worry about not being able to get home. But those will be later.

I am already past the planning and design stages, and am ordering parts. Already have all of the oil lines and fittings, intercooler, and BOV. Waiting on lots of piping, couplers, clamps, etc.
