when i said 15-20 horsepower i meant just from the
CHIPPING OUT he said it would increase my fuel curve and
make my redline higher im not really sure about this process though?

any thing else i could do to the head before putting it on
htat would be worth the money?? cam ect.....??

Hey man, for info on the oil orifice jet, check out this guy's VTEC swap. I have used it as a reference ever since I began to think about a Mini-Me on my own.

Hey I don't know much about the whole ECU situoation, so I will just make a suggestion. Won't you have to upgrade your ECU to OBDII if you use a d16y8 head and VTEC ECU? Currently you are OBDI, same as my car, and with a d16z6 you need NO conversion wiring harness -- the VTEC ECU fits right on in place of stock (the conversion harness is like an extra $100). Any thoughts, guys?

he would still need to add the proper VTEC wires because he doesnt have a vtec engine in there right now. Unless honda made one harness for every car with all the wires with or without vtec engine, man wouldnt that be nice

Default mini-me help!!!!

ever since i put the header on i noticed that when it was cold and i started it and it tends to "miss" its got somewhat of a dancing idle speed my mechanic said the header was loading up?? what ever that means and i was wondering if the new y8 head and injectors will affect this in any way
