    Custom Twin Turbo Kit forsale....$4000

    I'm putting my truck back NA. The Twin turbos where a blast but I need my truck as a DD shop truck. The kit is coming off my 2002 GMC sierra. The truck has a 8.3-1 CR LS1. The truck dynoed 572rwhp/580rwtq at 12psi. The kit works great. The kit uses Turbonetics 62-1 turbos and there rated a 550-600 hp each. If your looking for a serious kit to make some Big Hp this is it. Heres a List of everything thats included in the Twin Turbo kit.

    Two Stainless Steel tubalar turbo manifolds

    Two Polished Turbonetics 62-1 Turbos

    Twin Air-Water Intercoolers

    Ice Box for intercoolers

    Heat exchanger for intercoolers

    Electric Water Pump for Intercoolers

    Oil pressure and return lines.

    Intercooler plumbing and Silicone

    Two Tial wastegates with 7-8 psi springs

    Down pipes with 3-bolt exhaust flanges.

    Two Airfliters with elbows.

    I think thats about it.....

    Your will need tight plug wires with heat boots. The plug wires are alittle close to the manifolds. You will also need to tap the oil pan for the turbo Oil returns.

    Heres a thread with a few Pictures....

    Im asking $4000 for everything! Let me know what you think.

    Heres some pictures


























    Heres some video on 12 PSI. This was before I put a bigger stall in.

    My young nephew gets alittle excited on this race...

    This isn't a very good video but its against a very fast WRX STI. He made around 380awhp. I didnt brake stall when we raced and he did. I caught him on the top end. shouldn't it been the other way around? lol

    It will bolt up to your 5.3 with no problems. That motor should handle 7-8 pounds of boost with no problem. The wastegates actually have 7.5 psi springs in them. I have a few people that want it but nobody has sent me the money. If you want it just let me know. Im going to take it of the truck this week or the day that it sells. It is not to hard to take off.

    Thanks

    I just noticed your truck is a Z71 or 4wd. You may have to tweak the down pipes to clear the 4wd. Any exhaust shop should be able to fix that if it does not clear.
