Is the CEL on? Does it work?

Just because the bulb is there doesn't mean it works. When you turn your key to ON(II), does it come on for ~3-5 seconds, then turn back off?

xKevis

it does work i had a check engine light before for 02 sensor and i fixed it

So when it hits 6k, does it feel like it's run out of power, or does it act like it's hitting a rev limiter? Have you checked your mechanical and ignition timing? Did you replace basic maintenance items when you installed the motor?

xKevis

its hard to explain the car doesnt hit revlimiter but it forces me to shift
car runs fine

Then you need to check your timing.

xKevis

xKevis
