My car has 152K miles on it. It burns no oil what so ever. I am going to be replacing the timing chain, turbo, and heads in the next two weeks. I have a spare set of heads that i am getting a 3 angle valve job, manley SS valves, and some bowl work done. The springs will be the 980's. I am replacing my stock turbo with a TA-49. I am putting a Red Armstrong XP plus fuel pump in as well. What is the most boost i could run with this combo (see Signature) on race gas (race chip too), with stock injectors? Do i have the capabilities to go mid/high 12's?? Any input would be great.
