how hard would it be. i have a d16y5 in my hx and i have heard so a lot about how it flows poorly and i know the vtec e is just a pain in the ***. is it as simple as just unbolting the old and replacing with the new, then changing my ecu?

if i can do that it would be great.

thanks

my brother has the d15b1 vtec e pos, in his 94 vx hatch, im going z6 head with z6 intake mani, injectors tb, and the z6 vtec ecu.. itll work

so all i have to do is put the y8 head on with the y8 intake manifold and tb and plug in the new ecu and i will be good to go right?

I dont have much first hand knowledge with the OBD2 blocks, but I really couldnt see why you couldnt swap the entire y8 top end over. It's probably going to be plug and pray Both heads use the same config, and bore size is the same. You should have no problems, and notice a pretty decent gain.

Good luck

would it be a safe bet to go to a salvage yard and pull off a y8 head then send it out for a port & polish job? i think i could pick up a head pretty cheap around hear because there are a lot of civics in the area and even more in the salvage yards.

Why would that be safe? it sounds like it would be more expensive than anything? Full P&P jobs range from 550~1200

I'd just slap the ------- head on, and build a turbo kit for it

alrighty then...i guess i will just get one and toss it on. will the wiring harnesses for my car just plug right into a new ex ecu? since i do have a version of vtec it should have all the correct pinouts right?

thanks for the help...
