Thinking about a turbo upgrade. What options are there. Ive got a V1 intake. Ive heard the T33 mentioned and remember someone saying something about John Craig taking a stock turbo and making a 49 out of it. With my combo below what would be a good choice and how much, if any, modification is required. How much performance over a stock turbo does that 33 give?
Believe it or not, with the mods below, the fastest Ive been able to run this car is a 14.5 @ 94 mph. I have found out that my ignition is not firing all the way even, which may have a little to do with it, but with all the porting it always seemed like the car was crying for a bigger turbo. I can run with 32 psi (static) and 18-19 lbs of boost w/little to no KR! Maybe the turbo isnt doing enough? Or maybe the spark just isnt burnin the gas, and that is why I wind up putting the pressure down so low? Either way I know I could use a bigger turbo, Im overdue on lowering the ETs, by about a second or so.
