Civic EG

i was just wonderin i i can make the same power that way cuz that would save me alot of time.

moving to D Series for better responses

ok I thought about this... is this going into a civic vx? if so, you'll have a vtec-e ecu and a vtec head which will mean the wrong air/fuel curves and incorrect vtec crossover point. The easy way around this is to swap ECU's but then you'll need to convert to a 4 wire o2 sensor if this is a VX civic you're talking about (they come with a 5 wire o2).

Plus you will have a ulta low compression of 7,9:1

what about on the b7? that would be a sorta good combo good MPG + Vtec...

Are you talking about the b7 block or head?
