Hey Guys

After following a few of the r34s getting tuned of lately i decided to take the plunge and get my car tuned aswell. So after a few phone calls to CRD i organised the truck and shipped it down to Sydney. The car being a stock standard Vspec11 Nur with a Nismo exhaust i decided to add a few bolt on goodies of them being Sard 700cc inj with a Sard fuel reg, HKS fuel rail, Bosh 044 intank pump ARC airfilter box, Tomei poncams 260's, Apexi power fc and a ATS clutch to handle the increased power. Well what can i say Jim from CRD called to let me know how he went with it and i thought he was having me on exceeded all my expectations shipped the car back home and gave it a test drive and all i have to say is F*** this thing drives so much smother comes on boost earlier than before even off boost it is heaps more responsive than ever before. Oh i would just like to add this was tuned on 98 fuel and the turbos are the standard n1 turbos that come with the Nurs. So on this note i would just like to thank CRD you guys seem to be on a higher level when it comes to tuning and modding GTR's :D

Um is the second graph showing PSI?

As in your running 25 pound tapering off to 21 through standard 34 N1 turbos...

Do you have a before graph?

Should be one hellova ride though!

Yes i dont know why the boost tappers off it will hold 22psi it might be the standard wastegates on the turbos or the two cats the exhaust runs but yes it is a fantastic ride.

I expect it declines because N1s stop producing power at the top end over 1.3bar or so,

your car is going to 1.75bar at boost onset, then declining down to the best the N1s can manage.

Is there a boost controller in the mix as well?

Yes there is a HKS boost controller.

where are your torque figures?

On the first dyno pic up the side just under 9000

it feels very torquey when im driving it.

Wow - i thought N1s/-7s/GT-SS were out of puff at about 330kw...

Please put this in the RB26 turbo sticky.

+/- 20kw really, also consider its running a few extra PSI than what most people run (20psi) so all things relative its pretty much spot on :starwars:

ahhh, the beauty of stronger internals in the Nur motor. Congrats Nick.

Stronger internals yes maybe how much stronger!! well that can be argued all day long. Was it the increased strength that gave the power figure above in this instance no i don't believe this was the case either this one was done purely on tuning ability. This thread was not put up to compare anyones car this was put up by me only to share my happiness at my result. There's plenty of other guys on this forum with the same set up running roughly the same amount of power no records broken here just a great setup that has made this car so much more fun to drive. By they way thank you for editing your post if you would like to talk to me about getting more power out of yours pm me id be more than happy to tell you how.

Is there 2 different cars plotted on these graphs?

I see the NUR is making around 320awkws and the R34 GTR is making 358awkws.

So assuming your car is the red line who's is the blue line?

And what happened to the rest of the graph? Speed or RPM would have been nice to see...

      Its a 2002 vr-x four VQ25DET, silver. Coil overs, lowered, polished alloys and sport exhaust. Bit of a project, was sitting in a shed for a while but runs and drives great.

      I wasn’t able to replicate the sound anymore. It was a one time sound so maybe it was just coincidence but it was like small pebbles being dropped in a coke can.   should I try cleaning the MAF? It could be it’s functioning but dirty? I don’t know.

      Update 4: Hi all. The car drives again! Haven't driven for long, only to store it in the garage again, but the test drive was successful. The coolant and oil leaks seem to be fixed for now. Temps on the engine were also very good, while moving I never even saw 80C water during the approx. 30 minute drive. Ate up all the coolant in the reservoir though so will have to fill that even more when I go to the car next time. One thing that pisses me off is that the RPM gauge is still f**ked, I even resoldered the board twice and used copper paste on the silly screws that are used as connections. Next time I take it out I'll take apart the board and fit new components, I'll see if I can get a replacement IC for it.  I have an appointment set for 22nd of September for the engine tune to 370hp. Alignment also still needs to be done. My hope is that I can get all the legal stuff over with by the end of this season. Anyone of you have advice regarding intercoolers? Currently there is an APEXI core fitted, one of those weird hybrid ones, 600x270x76. I don't think it's bad but it's not new and now I still have the chance to change it now to legally include it in the paperwork. Only issue is that the only options that would arrive in time are a HKS Type R intercooler or generic Ebay spec intercoolers comparable to a JustJap one. Ideally I'd order a Plazmaman but it takes over a month to receive which would mean making the car legal has to wait until next season. Would love to hear some input on this. Same story for my injectors, the previous owner was a nunce and put ID 1050x on the engine. They work but are obviously not ideal at "normal" power levels. But I don't see a reason to change them unless the tuner says it's necessary. I read online before buying a different exhaust that the top secret style rear diffusers won't fit due to the size of the rear resonators. My buddy and I made it work by slightly "adjusting the shape" of the mounting bracket and making some spacers out of 3d print for the mounting bolts. Fits like a charm. Just putting this here in case someone has this problem. Even the hefty HKS Silent Hi Power rear can fits without hitting anything.
