He is running HKS Vpro stand alone system. The same system i will be running its very impressive and almost has too many inputs UPDATE: As suspected it was a little too rich in that rpm range. He leaned it out and the torque curve is almost perfect now and its making 599.6rwhp with 530ftlbs of torque!!!! and this is at 21 psi. egt is still real low af ratio in the hi 11s and the air inlet temps are still in the low 140s. still hasnt reached his goal of 600 though so we are going to try and tweak a little more tomorro. and also tweak on teh midrange to try and get the lowend to come on a little earlier. if anyone is interested i will post a viceo or 2 later. I was pretty impressed that the VG could make power like that. maybe that will be my next build

Oh yea what we are shooting for is a curve like this yellow line in the pic below This will also obviously increase HP also if the curve is worked out. I originally thought that the VG30's exh or intakes lack of flow (myth or fact) is what was causing it but since the timing adjustments started to fix it....I guess I was wrong. Anyways any help or suggestions would be appreciated. We will be hitting it again tomorrow night. Might even take some video if it get close enough to the goal of 600RWHP at 19 PSI

A buddy and I are tuning his Z32. He built up a vg pretty strong and it running ceramic coated forged pistons, hks rods and balanced crank. Stock heads (well stock appearing :>), ported and extrude honed stock exh manifolds, stock extrude honed upper intake manifold, a set of the new HKS gtrs turbos. he is producing 550rwhp and 480ft lbs of torque. he is running 106 race fuel. egt doesn’t get above 580C, total timing is at 30 degrees, air inlet temps are in the low 140s, A/F is rock steady at 11.5 all the way thru to 6200 rpm. My question is I have heard that with race gas you will not detonate you will just not make anymore power if you put too much timing into it. The problem is right now at about 5000RPM the torque curve takes a dive till about 5500 rpm and then starts rising again till about 6000 rpm In the pic below (not the actual dyno chart) the black line is the original run and the red line is the run after several runs of advancing the timing in that area to try and get a nice curve with one peak. Anyone care to comment on what else can be done to fix this curve. I was thinking since we have hit the limit on what timing will do.... leaning it out in that same area is the next step. We are being very conservative with the tune to stay as safe as possible and still hit the 600rwhp goal. Also what are safe A/F ratios when using 106 unleaded race gas.

I had almost 2 inches with the 275s and they still hit.... the urethane bushings cure that though.... developed a real annoying squeak though.

Mild steel rusts quick!!!!! Matt used SS piping on mine

Impressive!!!!! There you go guys the alternative to the rb26!!!!! That will be my next swap if i ever get ths one back I am wondering the same thing about the converter. Please post your results once its done. I will be running a 2 speed powerglide with a 6000 stall, and a big tranny cooler with an electric fan. Kinda wondering if it will be ok for the 45 mile ride to the track.

Here Is the site for pics of teh awd S30. they actually grafted portions of teh gtr unibody into the z unibody. teh intercooler is so far out becasue they had to mount the radiator on the front side of the core support. radiator in teh rear or a V mount setup may fis that.

I plan on clean up the tune and running 29PSI for 700+rwHP

Only available in Austrailia...... THATS BS... how come all teh good stuff is only overseas?

Yep... as long as you take the set your ok for swapping.

Z31 is the first gen 300z and teh z32 is the second gen 300 z S30 is the 240

IM sorry i just reread the post.... i wasnt saying to put the z32 rotor on the GTR... that would be a down grade. as long as you take the set they should interchange. IE z32 rotor and caliper should bolt up to a gtr (downgrade) and vice versa.

My buddy bolted a set of front r32 gtr vented rotors and stock gtr calipers up to his z32 with no issues.. I have heard its a pretty basic upgrade for the z32s here is the how to The z31 strut is a little different i could use the z32 caliper but had to use the z31 rotors the offset on the rotor was a little differnt. with a spacer or 2 the z32 or gtr rotors could also be used. and since the gtr calipers bolt up to the z32 and the z32 calipers bolt up to the z31 strut the gtr calipers should bolt up to the z31 strut.

you have to pay to read it??? anyone download it? if so maybe post a link to the full article or email it to me if you dont mind.
