hey Joel.....did you have to retard the exh gear to compensate and bring the power curve back to the left?

I'm abit confused, cause even though 9mm is not huge lift, when I went to school, bigger overlaps always caused a shift in rpm in a northerly direction.......maybe it's more to do with your tune than the cams cause I always thought that better response is not generally a side effect of bigger overlaps :blink:

:laughing-smiley-014: Back and to the left........

ahh ok.......sounds like an Ivan Tighe grind.

I though you may have been running a Poncam, HKS or similar cause they all run bigger overlaps than stockies

Tighe regrind it was.

I stumbled upon a list of HKS, Jun and LCA's but be buggered if I can find it.

I do remember the Rb20det's definitely had the same 110 and 115 LCA's when running in the 264 duration range.

Rb25's.. 115/115.

So would u recommend me get cams if I'm getting camgears, turbos, and injectors (and their support mods, fuel pump, water pump, afm, gaskets)... and if so, what type? I know nada about engine physics

-D

Cams always help make the power easier..

Don't overcam it. I was a little nervous 265's were a little too big but Shaun has had good results with that type of duration on fairly stock rb30det's previously so I went with his advice.

yeah we used to deal with Tighe Eng many years ago when I was still at Adelaide Eng, so I've considered going with one of his grinds as opposed to alot of the Jap stuff out there.

Good thing about them is that they don't just grind a second hand cam then end up with undersize lobes that have gone through the hardening process but instead they either start with a new billett or build up the lobes first. I find that alot of the jap grinds aren't really considering the average Joe that needs to drive to work through peak hour.

Sometimes I wish I still had access to our cam grinder and all the various masters that we had cupboards full of.

    • Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
    • Well the articals keep saying a Q50s (Skyline in Japan) with a new Manual gearbox. I like the talk about the new looks with the round tail lights. I hope they bring back the retro look like they did with the Z

    • Wanna rewrite all of that in, say, 2 or 3 separate sentences, so that we can read it?
