yeah ported and something else lol....

Mike I haven't seen a dyno with h22 making more than like 175ish whp stock so if you could give me a link that would be great. To add to the 175ish there is a kid up north that has the rmf header on his car with i/e/ and obdII to obdI conversion tuned with crome and he only made 175whp. We suspect that he will gain another 5whp once he gets rid of the dip when vtec kicks in. (it was also posted on honda-tech.)

Now with all that other stuff aside, lets talk about MSP's header..... I see that you have it in a hatch but have you guys actually test and tuned it IN a prelude that still have AC? Why I'm asking is because I'm working with a friend to design my own and it will only cost me about $400 bucks. The design is pretty much like the one above. So whats the price of it? Will I keep my AC?

Thanks
