i re-read me and Tloof's posts and there is a lot of conflicting arguements at first. However, we eventually straighten everything out, and if what he says about altima cams is correct then:
i wouldnt do anything. You are opening the intake valve 1.5 degrees after TDC. factory KA spec is 1 degree after. With a regular 248, you are opening .7 degrees BEFORE tdc. this is a problem. You have .5 degrees of advance, which is actually helping bump your curve up. However, .5 degree probably only shifts the power curve up a few hundred rpm if that.
So leave it alone. Definately dont drill for .5 degrees. That would require a completely different template, adn youre correct there is no way you could actually get something to wrok where you could do a .5 degree adjustment.
if you were really itchin to try this free mod, i would advance what you have an additional 2.5 degrees. or even throw your 248 in the exhaust side. I have, what was it? like 3.3 degrees of actual advance? you would have 4 degrees. Its fun, give it a whirl.
and i agree with checking dizzy timing, ive been using a lot of advance, but 92 octane is WAY cheap now, thank ****ing god.
