Hello, I need some insight on what may be going on with my KA-T.

When you first start the car and drive it the car will run and boost fine through all gears. Once the car gets warm the car will no longer boost, you can slowly accel to redline and the car drives perfect, just won't go into boost. Car does run rich.

I have done almost all basic checks, no vacuum leaks, no boost leaks, maf reads ok, distance from maf to turbo is ok all other sensors check out, fuel pressure is good, timing is good, swapped distributors.

Has anyone come across this issue?

Its a 97, stock motor, isis turbo kit, Z32 maf, 255 pump, enthalpy tune, HKS555 injectors.

I have had 3-4 different people look at this, one of them has worked in a shop that has done full build on cars, one owns a body shop/ repair shop, and I work in the service department at a dealership, we are not kids and not dumb, just getting owned by a little 4 cylinder Nissan. Please toss up some ideas, I miss driving this damn car.

Thanks for any ideas

Bryan
