Posted by Dave2turbo, Mar-05-02 12:31 PM
ok any help would be great ....i wanted more power before i turbo it
95 nt eclipse..so heres what i did 3 angle valve job ..ported and polished head,and intake..bored throttle body..and eliminated EGR tube
its runs super compared to stock !!!oh i did put n a magnaflow muffler also..ands its a 5 speed..so any suggestions on what size injectors i should buy feels like its leaning out around 5500rpm like it just flat lines...but pulls great till then..would the bigger injectors and a fuel pressure reg ulator do the trick thanx dave..

Our cars run pretty rich stock. Do you have an A/F gauge telling you the car is lean?

No injector change is needed unless you start boostin. I had my car dynoed at Wyatt's shop. Until I hit the high 4's low 5's on the tach I was running really rich. The ecu leaned itself out which is what caused that power to come on strong. As a matter of fact, until I hit that sweet spot I was running 10.6:1 air fuel ratio. Wyatt then showed me his dyno sheets and air fuel charts. It's amazing what tunning your car to 13:1 air fuel ratio will do.

Oh yeah. The stage 2 turbo kit with 18 pounds of boost probably helped to. 300 HP at the wheels. With no throttle body upgrade, no head work, no porting of the intake manifold, and stock cams with stock cam gears.

In closing, just get an AFC and find yourself a dyno to tune on.
