The Z will actually be a weekend track/fun car so geared more towards track and driven on the street. I'm just having trouble finding out if they are worth it. And the no top plates is also pretty annoying and adds even more to the cost.

Look up Ztuner on FB or his website and contact him about it. He has KWs on his Z and he's strictly a Z tuner, if you didn't take that away from his website name. Harry is a good honest guy and wouldn't lead you astray.

Wow man, great numbers! A long time coming - I bet you're pumped to have that bad boy running.
Quick question, I can't remember, are you running an EBC? MY 20G was always really laggy without one. I would try that before swapping cams or looking into turbine housings. There is no comparison to running off mechanical boost regulation.

Thanks s14unimog! It was a long time coming and the car is extremely fun to drive. As Ralliart said, EBC is controlled via ECU.
Some things need to change, but we are going to approach it one thing at a time. No sense in just throwing things at it and not knowing exactly what the best solution was. I'm hoping in another month or so to come back here with a different dyno graph with increased response. I'm not really looking to make more peak power on pump gas, but 500rpms decrease in spool time would be nice, however it might be a far cry. I may throw a race fuel tune at it too. I'd be interested to see what this setup can do with a better knock resistant fuel in it.

I've played with various types of mechanical boost regulation over the years and I can tell you that what I say is fact. Trust me when I say, this is not an opinion. Quote:

s14unimog, you are missing my point.
- The turbo he has is a terrible mismatch of wheel sizes between the turbine and compressor and reduces turbo efficiency in the spool regions (physics) - The 0.84 Open Scroll T3 housing allows to run more boost up top at the inherent sacrifice of spoolup (physics) - The engagement point from low to "high" cams (which on the VVL the intake and exhaust cams switch point can be adjusted independently) is VERY important to spool regions (physics) My point is, I do not think a simple EBC (which the ECU is much faster at opening the solenoid compared to any aftermarket stand alone closed loop EBC), which mind you, is going backwards in terms of EBC, is going to fix the inherent "issues" (and I use the term lightly as this is referring to spoolup and not an setup issue) the setup has with spooling so late in the RPM range. Again, my point is PHYSICS |

Calm down professor. I'm not argue with you on any of those points. I'm just telling my boy jr_ss that he's got a rad build and I'm stoked his car is up and running. Despite all of the points you're after, an EBC helps across the board - believe me or not I don't care. Let's not foul up his thread with this useless debate.

Hey jr_ss, how is the noise with the 044 in the trunk? I have a fully interiored car like yours and have been pondering moving my 044s (parallel) from under the car to the trunk as long as the sound isn't deafening. Thanks

I'll get some in car video tomorrow for you. I don't think it's loud and it's easily covered by the radio. I honestly anticipated it being louder than it is.

I don't want the thread jack Glenn's post but if you dyno the car with a 20g and those cams I would like to see the graph to compare to a 20g with 256/260 cams.

Yeah it will be dyno'd after it's all put together and finished. It's a greddy td06h-20g 8cm three bolt on an old Trust mid-mount manifold modified for lhd. Motor isn't crazy built just s4 cams, bc springs retainers, 86.5 cp pistons. Will be on aem V2. I'm only hoping for extremely reliable 350hp or maybe 400, but I don't see that happening on 91 pump.

That's what I've come to realize. Although a reliable 350 at the wheels will make me happy, since I'm pairing it with a cd009 and it's going to haul ass regardless.

Agreed. My car is stupid fast and I can't even use 2nd gear on the street. 65-100 takes seconds. I'm heading back to the strip this weekend. We'll see if I can get an 11sec pass.

This is a nasty build bro. You should be very proud of your skills. Hopefully some of the new crowd on here will learn from you and strive to bring there cars to your leval. I have been following this thread for a long time. Its nice to see it complete and being enjoyed. Its also reaparked the fire in me to get off my ass and complete my ve build kouki build. Thanks for the motivation bro. Whats your opion on the oil pump situation with these heads? Before you answer though let me throw my idea out here and get your honest opinion. My plan is to use a det pump and cut it at second horizontal rib down from the head mating surface. The take a de pump from the the same spot and tig weld them together. That would eliminate the need for alot of extra parts. For and oil pump that in my opinion isnt a necessary. Please give me your honest opinion.

Thanks for the compliments. I could only hope that my little build could inspire others to spend the time and dedication required to do a build. The car still has a long way to go, but it's a labor of love, not just a phase most of these kids are going through.
My honest opinion, use the VE oil pump. It is much larger than the DET pump and that extra oil volume is needed when the cams switch over and for the higher RPMs you'll be turning. Don't cut corners, it'll bite you in the ass in the long run.

+1 for ve oil pump. It takes a lot of pressure and volume to engage the second set of cam lobes. The only way I'd use a non-ve pump is if you were using vvl killer cams.

Speaking of oil pumps. Check out this pressure I observed on my Defi peak recording.... Insanely high... I'm thinking this occurred/occurs when the engine oil isn't up to temp completely. I'm running Brad Penn 15w-40.

Also, the 15W-40 is a slightly heavier oil as well, which will surely ass to pressure spikes!
And looking at the gauge, it is OVER 140PSI! I think I see 80-90 psi @ 7,000 RPM in my DET. That pressure is insane! Do you think this may develop into an issue with certain oils seals is such high oil pressure is sustained??. |

Like I said, I really do believe it's a pre-warm condition. I don't beat on it or boost it until the motor is good and hot. At cruise in 4th gear at 2500rpms tonight I was seeing 60psi. Dropped it to third gear and kept the speed and it jumped to 70psi. I do see it climb over 100psi regularly, but never that high once warm. I'll watch it the next time I do a 3rd gear pull once at operating temp to see what it peaks at. As for seals, the only one I can really see going is the Turbo oil seal. I do have the recommended restrictor installed but, at those pressures, it has to be seeing more than what the restrictor can regulate. What other seals could possibly be compromised by such high oil pressure? I wonder what pressure the oil pressure unloader valve is set to pop off at.
