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...

      Swapped rb25de neo how to get the gear indication on the dash to work

      By GTSBoy · Posted

      OK, so all I can suggest is that - if you have all the parts, and you have all the wiring looms, and you have all the electronic modules, then....it really is just a wiring problem. You likely have a damaged wire, pin, etc, somewhere.

      Getting lug nuts "gutentight" with no torque wrench

      Yup, bought this bad boy and hopefully it will be ready to pickup today. Had $5 credit on top of it so it worked out really well!

      Yeah it is really until until you get a feel for it....then it is easy. Which is no use to you really. I'd buy that torque wrench. One thing from sure, many (most?) tyre shots overtighten the f**k out of wheel nuts, so don't worry if they were tighter when you tried to take them off compared to when you do them up. I've had some crazy tight ones come back from shops, quite apart from the potential damage to the thread, I can't see a smaller person taking the wheel off on the side of the road

      Hey mate, thread dredging hahah To answer you directly, yes I had my itbs oversized and custom butterflies etc made by EFI Hardware in Sydney back around 2017-2018 if memory serves. My setup had a vast amount of other changes too though, so no direct comparisons unfortunately. i went from oem itbs, HPI manifold and internal gate hks 2835 pro S; to 49mm itbs, cnc port matched Nismo plenum, RB25 Neo lower runner adapter hand port matched, r31house v2 Takoashi MAX equal length twin scroll manifold with twin 38mm tial gates and a FP HTA3076 with 1.01ar twin scroll real hosing. feom power Fc to a link fury wired by 12volt, r32 gtr fuel tank conversion with frenchys twin 460 / surge tabk fuel hanger combo kit, 1659cc injectors, full 4 inch turbo back stainless exhaust, Z34 6 speed, Tomei 2way with 4.3 final drive and a ton of other shit. ive posted elsewhere here with complete run down, but here's a graph from its initial tune with no boost control on, 20psi gate springs only and e85.   7542AE72-DA92-4E0B-8660-B0940FEA7F24.mov
