After 3 engine failures I am finally back on the street with a Skyline - at last.

The R33 GTR is going again, with it's 3rd (& hopefully final engine build)

After the last fiasco just before the last 4,6&rotor nats in Feb (when we made 480rwkw then cracked the block on the friday before the meeting) the street GTR is up & running again.

This time the R33 has a brand new N1 block, new aries forged pistions, smaller 272 HKS cams (the 288 step pro cams from the race GTR are going into a 3 litre that Mark from Rhemac Motors is building for his GTR) & a conservative run in tune

at 1 bar. Tim has tuned the motec at Tilbrooks (who did an excellent job of getting the car ready) & the GTR currently has 375 rwkw (500hp).

The only other change is the gearbox, which is now an OS Giken Sequential 6 speed. This box has bigger dogs then the Holinger & should take the pounding of street use better than the finely tuned Holinger box(which is staying in the race GTR)

I have only started running in the GTR over the last week & hopefully will have it sorted ready for the skyline cruise later this month.

Hey my Dad used to be the engine builder at Rhemac Motors :D.. he retired about 12 months ago after 20+ years there :D.

good work John, whats the power curve like? also didnt you have a ppg box in their for a little before, did you get a chance to use it much and why the OS 6 speed?

Joel, yeah Tim Possingham now works with tillbooks and has done for a while now, catch up boy

The OS engine is still in the race GTR (which will hopefully be ready before the 4,6&rotor Nats/ & Drag Combat). Yes I did try a PPG box for a little while.

I am testing out the OS 6 speed because I like the sequential changes (& the extra gear)

It sometimes does'nt grab the next gear if not shifted firmly enough - will have to keep practicing.

The power curve is OK for now - is still pretty conservative(I want to get some use out of this engine - not blow it sky high like the previous setup.)

I thought I'd seen the beast tucked away at work a few times lately John. It inspired me to bring mine out for the daily commute a bit more mate! Congrats on being back on the road. Feels good doesn't it?

Tim is a damn fine tuner and I have no doubt that this motor will hold together over the long term. A little less power is much better than another failure! And more money/time.

I'm toying with the idea of going for a bigger turbo on my thing... not sure exactly what yet but 'nicely' into the 300+rwkw region would be the aim. See what happens I guess.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      310mm rotors will be avilable from Australia, Japan, and probably a few other places. Nothing for the front can be put on the back.
