vtec...what's all the hype?

[doug294]

I blew a head gasket not to long ago and had a Y8 head laying around so I decided to go ahead and put it on. Well I couldn't tell to much difference with the y8 head than the A6. Looked at the cam gear and it was at +2 degrees. Somone told me to retard it -4 degrees. It fixed the idle problem but it feels like it misses a little climbing through the RPM's and feels bogged down. (will advance it to -2 later)

Anyways. I also wired the vtec up while I was at it.
I can't feel any difference when vtec is activated besides the fact that I can climb higher in the RPM's. Without it it would stop at 6k now it will go past that. I guess the SOHC vtec isn't to much of a power gain.....are they more for fuel eco.?

Also what is the proper advance/retard degrees I need to set my cam gear at.

as a general rule, on a SOHC engine, retarding the cam gear will gain horsepower up top. advancing the cam gear will gain power on the low end.

You should've felt a pretty nice horsepower gain withthe y8 head. Higher compression, larger valves, ALOT larger cam.. you just went from a 108hp engine to about a 130-135hp engine (higher compression than a stock d16y8)

Just a quick question... when you adjusted your cam gear, did you remember to check and reset your ignition (distributor) timing?

Crap, no...I didn't know I had to do that. What do I do to do that?

Its a lil plug located on the passenger side, below the dash on the sidewall, pull it out for a few seconds and plug it back in and thats it.........

what you talkin about boy? to set ignition timing on the dizzy, you loosen all of the bolts on the distributer, and rotate it until it is in correct time

I think there is some confusion here. To set the ignition timing you have to jump these 2 wires on a plug that is on the right side fender for 88-89 and I think its in the car somewhere on the 90-91, that puts the car into a special mode. Than you loosen the distributor bolts and use a timing light to set the timing looking at the crank pulley, than tighten them and pull out the jumper and you are good to go.
