Re: Vitara owners chime in (about timing)
I would.
In the HMT tradition, you probably should run without it for a minute and if the power is good and it runs sweet don't worry about it. However, with how all these engines are getting old and have been apart once or five times and have been cut (decked/milled) the mechanical timing is guaranteed to be off a degree or two.

Re: Vitara owners chime in (about timing)
I do have my head and deck milled, only a total of about .015 between the two you think that would make a difference in cam timing? I do have an adjustable gear but keep it at 0 since I havent had it on the dyno. I dont understand how you true'd up you're cam timing could you elaborate on that JD? thanks. Do you use a protractor?

This is for D15/D16 that *aren't* running D16Y heads. You also have to have the correct crank pulley and lower timing cover for your bottom end, etc. D15 stuff doesn't work on D16 stuff, and IIRC D16A6 crank pulley is ~2 degrees off when installed on a Z6, because the Z6 lower timing cover has it's timing pointer in a little different position. You see a LOT of stuff like that, which is why there are so many variable results out of D16... I try to find an original engine and just build that. Anyway, I digress.
1) Center your distributor
2) Make sure your timing is locked at 16 degrees. If you have Crome, Hondata, eCtune, etc, just blank out a large portion of the maps with 16 degrees or use their timing lock function (if they have one). That way if you are idlding a couple hundred rpms high things dont get screwy.
3) Adjust your *cam gear* to get the engine into 16 degree base timing.
The engine is now in perfect mechanical and ignition time, just like an OEM car where the distributor is always centered.
Keep in mind if you have a regrind the timing may or may not be correct, and a lot of the aftermarket billets aren't anywhere close, you just play with cars like that until they run right.

Re: Vitara owners chime in (about timing)
thats interesting, thanks I'll try it. I do have a delta regrind also so hopefully this helps out. I tried one of xenocrons timing maps out of his bin depository and converted it to my 3bar map and I must say it pulls harder thats for sure but the ign. timing is advanced 6-7 degrees more than what I was at 20psi or so.
