R33 GTR

Nismo 1.2mm metal head gasket

Racepace cam gears, but not yet adjusted

Garrett -9's with 1 bar actuators

Nismo fuel pump (rewired)

Mine's front pipe

3" test pipe

3.5" Tomei Ti Expreme

Greddy Profec B spec 2 (disconnected)

17psi on standard ecu

Soon to be added: PFC, ID1000, Z32 AFM, E85

R31Nismoid claims 280rwkw on 18psi @ Racepace dyno with his stock ecu.

To be honest I was expecting much less though - around 250rwkw.

I would not be surprised if it were to read lower on a dyno dynamics roller dyno.

Point of my dyno check was to ensure AFR is safe, timing is accurate and no knocking - all of which were achieved.

Also I'm very glad to report that there is very minimal boost drop from the Garrett 1 bar actuators with only a small amount of preload wound in.

Reaches a maximum of 17psi at 4,000rpm and does not drop below 16psi all the way till redline.

When it gets tuned, I will get the cam gears dialed in and reattach the boost controller to keep the gates shut for as long as possible.

Looking forward to some good improvements in the response department.

I'm not a doubter because I have no clue about these things but I just haven't seen it before so I was amazed.

Keep up the good work though and as long as the AFR's are sweet and you're happy then that's all that matters

Nah, I'm talking about Grant, cos I know he had his old 33 gtr tuned by Trent and got a little over 300kw on the same dyno with similar mods and he had PFC.

To settle any doubts, I think it seems like quite a normal figure. Although peak power is quite similar, you can see where the gains are with the car properly tuned.

50Nm difference in peak torque. Reaches almost exactly the same spot (Approx 4200rpm)

80kw vs 95kw @ 3000rpm

190kw vs 210kw @ 4000rpm

220kw vs 265kw @ 5000rpm

260kw vs 300kw @ 6000rpm

If Grant doesn't mind I'm happy to post his graph or he can so people have something to compare with.

Or it can be found in the RB26 dyno results thread anyway

Unregistered Dark Blue 34 GTT on way to Vicroads - don't worry, it's registered now.

Congrats! Didn't spot you sorry, maybe I was too busy focusing on make do GPS and rushing to get to Trent's cos was running late

No stress, with that colour, it'd blend right in traffic anyway!

Fatz, he's talking about my first 33r with GT-SS's not the last one.

Michael, post them up, btw I didn't doubt you. Just found it interesting that you achieved with standard ecu.

Probably says about your motor being healthy - I was told mine had low compression in cyl 2, didn't know of it until I enquired about buying motor/box back. No idea how long the cyl 2 were down for, never done a compression test on cars I buy :/

Grant, nothing unhealthy with that figure at all. As you can see, by 5000rpm you're up by a massive 45kw.

Don't think you mentioned cam gears either in that recipe. Obviously some more gains to be had in the mid range.

That along with E85 would have been pretty damn quick setup. Also you didn't have fuel pump, injectors or afms upgraded which would have been the limiting factor to push any further.

    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
