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...

      Yeah hopefully some rich muricans fly to Australia and go on a R33 buying rampage and offer you and I a sum we both can't refuse. (Nek minnit moron here buys another R33 shit box to build).

      I guess you can guess the reaction when I said maybe I should cut my losses with her.  I didn't but sometimes you know, I might think that... On a more positive note. At least R33's are worth something now, so it's not a total loss.

      Mine said exactly this, your boy here pumped like $40k+ into it. Smart, follow me for more investment advice. #buyhighselllow

      Agree about euros.  Pulling apart is so much quicker than putting back together. Made worse when it's been a while and you can't remember everything. Any modified part seems to always be a pain to reinstall too and complicates things. There's not too many mods on my car but those that are caused difficulties. Simple things like the radiator that should just drop in, needed some finesse and additional time to manoeuvre in, same with oil cooler plumbing, head drain etc. Simple things seemed to want to fight me the whole way. Stupid standard intake plenum didn't help either. After nearly finishing everything, I saw the 2 knock sensor plugs and cold start valve plug hanging there. Was able to contort my hand enough and looking at an internet pic of valve, was able to just get the plug on and seated. Front knock sensor was similar, the rear however I can't even see. Going to have to remove starter motor to create access. FML. I've consumed that many cans of V in the last few work sessions that I should get a sponsorship. edit, I did the same with the mic and bore gauges. Spent many hours, it's one of those things that you get better at and more confident the more you use them. There was also so many hours spent searching, just to try and source valves and valve guides. I think I spent more time on trying to source valve guides than actually measuring and assembling the motor.

      For me a few things compounded the issue.  - Wanting to learn a few aspects, such as hand lapping valve seats (10hrs-20hrs) - Wanting to balance the rotating assembly down to 1g on cast parts, (15hrs easy) - Not knowing this wack FWD platform, 10hrs to remove to remove the subframe/engine etc - Having never used mic or bore guages etc, thinking I was doing it wrong, finding out 2 rods were oval and I was correct (10hrs easy).  And the list goes on, each shed session was 60-90mins so it takes a lot of them On the contrary, when I sold the CA/Box/ECU it was 3hrs to remove, split, put on a pallet solo having never done it before.  This is the reason that the XR5 will get sold and I will go back to a JDM daily. Euro stuff is painful to work on.
