Beginning my 2010 Build... Thoughts? Well the STS setup got me solid mid 10s, but I've been itching for something new so I'm doing my own custom front mount for this year. The STS setup consisted of the stock STS piping with a TC76 (.81 exhaust), FMIC, untouched 241 heads, Patriot duals, ARP bolts, LS6 cam, 255lph with BAP and 60lb injectors. That was the gist of it anyways...
For this year, I'm using a stock drivers side manifold with my own custom manifold on the passenger side. The custom mani will have 1.625" primaries leading to a 3" "log style" manifold. The cross over will be 2.5" and will feed into the back of the 3" log manifold and then into the turbo. I'm reusing the TC76 but getting a 1.15 hotside to replace the .81. I have a Tial 38mm wastegate with an atmospheric dump, 3" stainless downpipe to the firewall then transition to 3" aluminum to the stock exit location. I am also redoing the fuel system, using 2 255s instead of the one, ditching the BAP, and running an 8AN feed and using the stock feed as a return. I am also going to 120lb injectors and will be running E70/85 exclusively.
I am also putting on a set of 317s and fastening them with ARP Studs, MLS gaskets. I don't know how much I'm going to deck off of the heads. Compression ratio with 67cc chambers is ~9.3:1. Diamond forged dished pistons, Scat rods.
I will also be sending the Yank converter out to get it restalled with the new found power. It was a little loose last year anyways.
So... thoughts? Comments? Fabrication has already begun...
Doing this all in my garage with my buddy.
