FULL Hotparts Turbo T4 Kit Vortec V8 LS 4.8 5.3 6.0 6.2 Silverado Sierra LSX 3"

Overall definitely helped having this kit. The wastegate flange was a pipe shoved 1.5in in the 2.5in tube blocking flow very bad. Cut the pipe out and welded on a 50mm vs racing wastegate in same spot and controlled boost beautifully. Wideband location is not possible lol 😂. Who came up with that. Also DO NOT use the 3 bolt gasket they supply as it is not rated for exhaust manifolds at all. Match up a 3 bolt gasket at parts store as well as getting some oem exhaust manifold gasket and not a single leak.

Thought these were a good setup was easy install and everything fit well., but once the truck was strapped down and we were tuning on the dyno... we found out there was a major problem... we couldn’t control the boost cause the waste gate is mounted where it’s mounted.., had to take manifold off and add a wastegate right below the turbo... and move the O2 sensor cause that’s where we welded a mounting ring for the wastegate.., very bad design.., thought it was going to be easy but turned in to wasting a dyno session and a day in time to mount wastegate in different spot so it would work.,

Perfect fit for 69 c10. All parts included are high quality.

💯

The cross under pipe with the fange for the waste gate broke off after 624 miles. The weight of the waste gate was enough to cause the welds to break. The clearance for the spark plugs on the Log manifold needs to be enlargened. The dump pipe hits the clamp for the crossunder pipe, and had to be heated and hammered in . Save your money and build your own.
