G.I Bolt on Twin turbo kit
im thinking about selling off my old turbo kit since i wont be using it on the new 427 sb
here is whats going to be included
2 gt3076 turbos good for aprox 550 hp each
2 38mm wastegates with 8/12/18 psi springs
2 log style headers , 1.5 in heavy wall primarys , 2.5 inch log heavy wall ( mild steel) t3 flanges and flanges for 2 bolt 35/38mm wastegates ,should support 1,000-1100 hp
2 2.5 inch downpipes , no mods requires other then slighlty bending one of the factory brake lines , these exit behind the front tires under the rocker panel , can be cut to make into a true dual ex system or for ground clearanc eon lowered cars
1 charge pipe from turbos to intercooler 2.5 inch discharge from turbos merge into a single 2 inch pipe ( mild steel) has 2 rfl blow off valves mouted at each turbo discharge ) these are very very loud
i am keeping the 32x12x4 intercooler and the aluminum 3 inch charge piping from the intercooler to throttle body
also included is the oil drain system which drains back to the fuel pump block off plate ( dual -10 an drains ) and dual -4 feed lines
2,500 + shipping
to replace the inetercooler and pipes will cost u about 150 bucks

its still on the engine so im just seeing how much interest there is on the kit
a fe wother detials is this is setup for a car with dual fans and v-belt it should clear a serp car with an ac delete , and u can keep ac on the vbelt setup but air filter clearance is an isse
