on my 94 16v 1.5L ive got the header for the 1.6L v-tec motor installed at the moment, and this is causing low backpressure up until the 3000rpm point. i was just wondering if putting on the stock header for the motor would get rid of this problem, and i use the car as a daily driver and like to get my power right away.

also, i have a ported and polished intake manifold for my 1.6L v-tec motor, and was wondering if i could install it onto the 1.5L 16v thats in my car right now.
