Building a semi fast street fun car 1983 280zx, running a stock l28 with head studs and turbo gaped piston rings. Now I am not a gas car expert. Mainly worked of diesels in my life so first time boosting a car any tips would be great. I have the inter cooler mounted and piping and blow off valve done, car has headers that I am going to run under the oil pan to come up on the passenger side. Car has 19lb injectors Bosch and run about 60 psi already using the xfi street computer and wiring harness on the car with a 255lph fuel pump . Guess my question is can I run 18-27 pounds of boost?
