hey guys atm i am working to make 200rwkw after my last dyno of a shit 140rwkw due to poor tune and lack of a few things

Mods last dyno

Gts-t R33 rb25det

Link Plug in replacement ECU tunes by poor shop at 7psi on 95oct fuel

PWR INTERCOOLER

K & N POD

Trust Catback

Now my new plan is mod then retune it at MRT in Sydney On 12psi and get near 200rwkw

New Mods that i hope help me get to 200rwkw

Dump and front Pipe Twin set up off BOS

Hi flow Catco cat

PLUMB BACK BLOW OFF VALVE caust stock one isn't working right Flutters on 7psi

loud ( NOT sure on what brand anyone know any good ones for Plumb backs

custom 3" pipe intake from turbo to Pod without AFM due to link computer

last of all thinking Cam Gears but will they heap on stock cams

anyone know if cam gears will gain more power r they worth the money also what brand

OS GIKEN or TOMEI

thinking about new Timing beat too while cam gears r off

what u guys think

Those mods with a good tune should push you to that figure, or very close to it.

But if you looked in the Quick Ref guide at the top of this forum you would have seen the following threads

Ex. Cam Gear: http://www.skylinesaustralia.com/forums/sh...41&page=1&pp=25

Dump Pipe: http://www.skylinesaustralia.com/forums/sh...ead.php?t=10567

btw, 140kw is what you would expect for a near stock Skyline. That must have been a really really bad tune..

I know 140rwkw is low but i beat one of my mates with a gts-t with a full exhaust so i am guessing maybe the dyno was just out been just beaten by a 180sx and onces by a gts-t with least mods then mine he was a better driver

I am Hoping its just the Tune Mrt will work out whats holding my Power back

Tony,

Cmon you should know better ;) Those are the "Revision 1" HKS gears. The "Rev. 2" gears -- which use duralumin -- don't appear to have the same problems.

Edit: I'd still look at getting the Tomei gears as part of the camshaft + camgear packages they do.

Cam gears will make some difference, but not 60+ kw. (AFAIK, all they do is move the power band, they don't necessarily make more power).

I suspect it's the tune. I'm running a RB25DET on a Wolf 3D. It has VVT, and is otherwise stock. It was tuned at 10psi on 95 octane, and pushes 180 kW out through 4 wheels (R32 GTS4). Granted it does also have a "hi-flo" cat and a dump pipe, but still runs the factory air box and filter.

Hey whats the deal, is there something freaky about my car cause i got it dynoed with minor mods (see sig) and even at 7psi it was pulling 169rwkw, and was 186rwkw @ 10psi.

Was dynoed at unigroup, i would have thought scottmans would have been more powerful...

Must be UBER dodgy tune

i have no idea why its only 140rwkw i am hoping to try and fix it hoping its just the tune

other things it cound be is Fuel Pump or injectors or something MRT will find out hoping to fix it :P

still i own lots of shit with 140rwkw :blink:

I thought it was shited so i went and raced my mates Gts-t r33 with a Full Exhaust and BOV and i beat him so i have no Idea maybe it was the dyno

If you want to try adjusting the inlet gear whilst keeping the use of your VVT, PM me.

I've got a little invention that may just help you out.

Yo bass.Have you made some for r33 now.Or is this a trick that you have up your sleve.

I have the newer HKS gear and its fine....

Didnt gain anything at all... Just got a few more km's per tank and smoothed out the top end.... No jerky action inbetween 6-7000k....

AND more importantlly i got FLAMES>>>>> LOL

Scottman, what dyno was it on ? The dynologs read alot lower than the DynoDynamics ones (most common).

I just had car on dyno yesterday to retune, and all i could get was 145 rwkw's (Dynolog)

(was tuning it myself)

Now bear in mind this is S1 R33 GTST, std turbo

3" turbo back, and i just put a 4" magic cat in (which does work well by the way , 4 gas analyser confirmed)

I have a plug in LINK. No AFM (3" SS Pipe to pod)

Carbon cleaned it too.

R34 GTT cooler

And just fixxed the coil probs with a mates 32 GTR coils borrowed till the splitfires arrive... also new BKR6EIX iridiums (.8mm std gap). After last tune the coils shat themselves , siliconed them to get by, but power was flat...

Also fitted a MV auto shift kit.

Its been a busy 2 weeks !

Heading out to drags again tonight to see how it goes...

Two weeks ago with it feeling flat it ran a 14.6 @ 95.3 mph So i hope i can get a 13 tonight ... time will tell.

I think you should go out to the strip and just see what mph your getting ......that will be a better indication of how well the cars going.... as your dyno may read low as well.

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.

      Does the scanner do all the CUs in the car, or only the ECU?

      R34 N/a And R34 Turbo (gtt) Transmission.. Uh, Problem.

      By albyz34gt · Posted

      @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man

      Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
