Turbo Hookup????????????

The stock engine modded with 340 valve springs and a copper head gasket ended up going 11.77 at 117mph before a piston got hurt. I was running nearly 30psi. Home modded Holley 600dp, walbro fuel pump, mallory regulator, ported clifford intake, and a Buick based turbo. Lots of ebay parts (intercooler, BOV, pipes, clamps, silicone hoses...etc). Watch the AFR and timing and it will live. I had 30 full track passes on the engine and 3000 street miles with a lot of beating. The engine was in good shape when I started and had 80k miles on it when I started the project. Compression was down to 90psi per cyl (70psi on one) when I pulled the engine. I started with about 120psi per cyl. I have it as a back up.

One trip to the track and back (100 miles), I made 3 passes and averaged around 19mpg. The turbocharged slant needs a 2.76 or at most a 2.94 gear.
