Steve, i think the reason why some people find the results abit fishy is because there have been a few cars with high hp power readings with no track time or not equivalent times with less then the usual mph. Every one has different views and im just writing what i seem to notice.

ps: jezrrr great results from such little modifications.

Cant deacrease scanned image of dyno graph sizue enough to attach.

Its a nice power curve though.

I will get 300RWKW out of these turbos BUt first need bigger injectors (currently running at 90% max) and will be getting stage 1 HKS cams (264 int 264 ext).

May upgrade to GTSS turbos later but want to see what I can get out of the stockers which, in the GTR 34's, are steel wheels and ball bearing.

you never mentioned what boost you guys ran? I't would be good to see the dyno, & your af ratios also..

ps: steve... so touchy mate :relax: like you say, we here are probably just a bunch of keyboard warriors :D no hard feelings... it makes for a good comparison when we can compare apples with apples....! not dyno queens running 20psi on stock turbos, with af ratio's bordering detonation... that's all..!

Dont mean to interupt your thread but seeing as tho i got a 34 i thought it would be good to compare results.....I got 245kw with 1 bar boost,ganador cat back pipe,japanese "Sift" rewritten ecu...the rest was all standard...i then fitted HKS manifolds,HKS dumps,GT2530's and a trust plenum and at 1.1 bar boost got 298kw.Now fitted HKS cams and gears havent fitted the engine yet so havent dynoed yet....still has the standard front pipe which i will replace after a short dyno run when its running again

Be careful about that assumption though they are ball bearing....

I am running 1.2 bar of boost.

The turbos are safe at that level. "Mr HKS" has acheived some awesome ressults on his R33 GTR. He is getting 421 RWHP with GT SS's @ 1.1 bar of boost !! He has some very nice other mods but is not even running hot cams. He was getting 400 RWHP before moving to the GTSS's so theres some room for improvement.

Ken,

ive heard different things about whether theyre steel or not but the consensus is that they are at least from what ive been told  

Jeremy

N1's yes , std no.

btw , that came from Mr Jun when I was talking to him about some R34 terbs at Speedworks about 12mths ago

Cheers

my r34 gtr made 248rwks with mines ecu, pods, exhaust and 1.2bar.

ran 12.8 at 109mph at willowbank with 1.90 60 ft... but didnt really pull that well top end with the mapping in the mines ecu...

so your 278rwks is great , should do a mid 12 if you launch it hard...

since then have gone a little silly fitted hks2530's & hks dumps, 700cc sard, nismo fuel pump and reg.z32afms and super induction kit, power fc....

hope for high 11 or low 12 now even on close to base map in the power fc.

i will be going to the track soon if it stops raining in brisbane everyday....

I will be launching it hard but will have to wait till the HKS twin plate arrives. Those times are pretty decent, what pwoer are you getting now with the 2530's, did you consider the GTSS's ?

Hi guys Steve-SST has kindly posted some interesting times and power for Skylines (I have taken the liberty of adding rwkw for the metric minded). If we pick out say 5 Skyline examples and we all put down our own personal experiences, maybe we can shed some light on this……

1. “An R33GTS made 306rwhp (240 rwkw) and ran 12.3.”

2. “GOTBOOST from this forum ran high 11s in his GTS with 344rwhp (260 rwkw) on my dyno”

3. “A GTS ran 13.4 last weds with 270rwhp (205 rwkw)”

4. “GTR ran 11.4 with 387rwhp (290 rwkw)”

5. “Simon Nattalotto from this forum ran high 12s with 285rwhp (215 rwkw) in his GTS”

How does this compare with others’ experiences? No BS please, real timeslip and dyno numbers only.

As an update - Ive just come back from racepace where my car produced 255rwkw @ 15psi boost. We didnt want to increase the boost right now as the car is heading out to Phillip Island next weekend and 15psi is safe for the stock turbo's there.

But there was a power increase of 20rwkw when we upped the boost from 14psi to 15psi so I could see a figure very similar to that produced by jezzrrr @ 1.2bar.

So I got a nice 77rwkw gain by changing over to the power fc, adjusting the cam gears and a slight increase in boost. Very happy with that. And the power delivery is so smooth now. :P

LOL - your car has taken longer than mine. And it was still in bits this morning! My car was meant to be there LAST tuesday but only made it today. So good luck with getting it there on Friday! :P

Dyno took a couple of hours I guess. Didnt pay 100% attention to exactly how long as we were there for ages (I had to run Gerald around to try and find a M7 bolt) plus the cams hadn't been adjusted or the power fc fitted before we got there. And Im not sure as to cost considering I've also had a new clutch, plugs, oil cooler and pads as well as the power fc and cams fitted this last fortnight - and Im not sure of the exact individual breakdown of costs involved. I just know Im broke now.

      Leak from Tokico BM50 Brake Master Cylinder

      HFM BM57 has a "bad" knee point, IIRC. It's not the same thing as the later R chassis MC.

      Who has a Infiniti Q60, Q50 (V37)?

      The ATTESSA is functionally identical to R34; there were a bunch of JDM models that continued ATTESSA including Fuga/Q70, Skyline/Q50, Cima etc as an option. All with Auto only and I think mostly for snow regions. AFAIK there were no AWD VR30DDTT sold in Australia - it is on my to do list to check regs for racing a LHD car in Targa/ATR/AASA/CAMS events because if I can get the auto to work it would be interesting to run a 4wd car The Ecuteck TCM tuning is the same model as their ECU tuning, they already have it for R35 and Dose's favourite, BMW. You buy "points" to allow your computer to be tuned, buy either a bluetooth (phone app) or bluetooth+USB+Key (phone and PC) dongle, and pay for a tune that will be locked to your tuner ( ). You can also access the tuning software yourself but 1. it is mega expensive and 2. these computers have a billion parameters that intersect, so how could you ever spend enough time on it to get a decent result.

      Or, is it a case of what it is like owning an R series Skyline? NFI what the previous owner has done or fiddled with... Ha ha ha After reading through this thread, I went on a bit of a research about the Q50/Q60. Now I'm quite intrigued by them! Is the AWD in them more like a WRX where it's always AWD, or is it more like the ATTESSA in the GTRs? By the sound of this TCU tuning, this sounds like a case of someone has made some real software for it, and you just need the right piece of hardware, and then you license that specific vehicle/TCU. Or is this a case of the software will be really expensive so only a few tuners have it, and you still have to pay a license per vehicle?

      By popular demand.. it was a coil. Got my hands on 1 new OEM coil, replaced with the one that made the less noise difference when I unplugged it while the car was running and started the car up. No stutter and the engine light was gone. I guess I’ll buy the other 5 they have lol

      No, code 21 is very straightforward. It can only be the things described in that diagnostic flow. In fact it has no way of knowing that the spark plug resistance is out of spec.
