He’s going all motor. lol j/k. It’s perfect for 500-700whp but Eric is gonna need a bit more than this kit was built for. 900whp is asking too much. Eric’s gonna need a 4" downpipe, 4" exhaust, 3" charge piping, and a much larger intercooler. He wants to run a divided manifold to help in spool up, I’m not even sure the gtx42xx will fit under the hood with this manifold anyway.
