What motor and trans are you running??

If your running the B16 trans you can't fix it with out doing gear changes in the trans.

I'm assuming you probably are, because with my B16 I had it was the same deal. If your not worried about losing power, throw an LS trans in it. Its not A LOT better, but better all the same.
