Which cams (ie how much lift?). Check out this graph. It tells the story. The HR springs + shim set are slightly cheaper than JWT from DaveB IIRC.
My cams for my n/a motor=260/260 duration 10.9 lift.
Jwt doesnt recommend going above 7200rpms
My "former" machinest suggested no more than 7500 with the: jwt springs, arp rod bolts, & stock oil pump.
So im still thinking about reving to 7500 with a jwt ecu.
I read the graph... Its seems as though I will be better off with the Vq35HR dbl shim next build. Thankyou.

^^^ Kevin, are you buying his motor?
Dan, that is very impressive. Are you planning to beat this at the track, or take it out, sell it, and then drop in the 3.5?
I'm curious, what's your next project after the Maxima? Have you been thinking of that?
Also, which tracks are you hitting this year, if you haven't started? I saved my light rims for Cayuga, but if I sell them, I'll be keeping the I30 as a daily driver, and picking up something smaller and lighter for the track.

I think the stock oil pump might be ok at 7500, as long as you have the stock crank pulley on there (ie damped), but I can't be certain. SR20DEN was revving up there for a long time and IIRC he didn't even have a stock pulley, but I could be wrong, I'm not 100% sure.

Next project after the Maxima will be a RWD setup. I haven't decided for sure on the platform yet but there are a few I'm considering. In any case that's still a few years off.

Hmm, dunno... but I'm not putting any more work into it now, not worth it to me as the 3.5 awaits. The heads were not ported but I did do some bowl and surface finish work throughout, casting cleanup, etc and the openings (heads to LIM to UIM) are all well matched also.

Check out the spec on the stock 3.0L heads versus the same P & P:
Stock P & P
Intake port width: 55.35 mm 57.50 mm
Intake port hight: 32 mm 34.50 mm
Exhaust port width: 44.65 mm 49.50 mm
My vernier caliper was calibered just before taking measurement.
On the intake port I couldn't shaved as much material as I wanted, I was limited by the LIM's ports width, it's pretty much the maximum I could shaved.
The inside of the ports are also much wider than they where originally, those heads will defenitely flow much better, but that's all theory until we dyno'd.

Well there is a lot more to porting than just hogging out/opening the whole passage up, sometimes that's actually counterproductive (as I think I've mentioned before).
But anyways, I'll look forward to seeing your results, I hope it turns out well for you. Any idea when you'll be ready to dyno your engine?

In some cases even ADDING material in certain spots can be beneficial. It's all about velocity, even at high RPM.

Congrats again on those great numbers.

Specially near the valve bore, the air flow doesn't like 90 degree angle but I'll ask the machine shop to flow bench the heads and see the result.

.. or something that does the same thing. I didn't get adapters, I had my sprockets machined and spacers made...
look here for a pic of what I mean

Dandy those are some serious numbers. I will be happy to see that number on my 7lbs of boost, that is awesome. Now i can rub it in my friends K20 RSX that the VQ30 has some potential too with the right person behind the build. NICE!!

i really hope my eu can do half of what u did with urs. those are impressive numbers, they deff inspire me to get my car up and running
all u powerful 4, 4.5, and 5.5 gens are out there kickin a$$ we need more 5.0s im working on doing my part. hopefully 250whp at one point

Holy Crap Dandy thats crazy!!!
Its funny. Your HP numbers are putting some of these VQ35 guys to shame. If only the VQ30 made the torque the 3.5 made of.
Its going to be nice to see what your capable of making with a VQ35 properly tuned and driven.
Way to go man, huge props!!!

Yeah that was a key part of it for sure. If not for the oil pump I could have gone to 8000 easily, maybe 8200. Thanks again for doing the spring pressure testing, that started my wheels turning when I saw I actually had some numbers to compare.
