Fast 90/90 problems......
Fast 90/90 problems...... I have a fast 90/90 setup that I have been putting on my conversion. Not impressed with it, especaily the throttle body. The throttle body is the one that comes with the fast manifold. The Wilson throttle body is sticking coming off idle. Does any one else have this issue...and if so what did you do to fix it? I also had issues with putting the 90/90 back together after port matching it. I had to bolt it to the heads before tightening the outer bolts in place. My 98 vette fuel rail had issues fitting it too. Had to trim the manifold some to clearance the fuel rail. Then bolting the throttle body to the manifold. What a joke!!!! I used all 5 of the throttle body mounting holes to ensure it was mating to the TB gasket correctly. For the money spent so far I am not impressed with it!! Any feed back and help is greatly accepted!!!
