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.

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.

      R34 Skyline Sunroof Won't Tilt/Vent

      By ShezzDogs · Posted

      Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!

      Do you have some data like fuel pressure? It's really hard to say if you're still fighting a fuel system issue at this point. Could be something weird like the FPCM dipping out.

      Steps to DIY sanding car back ready for respray....

      Yeah in that case, pulling the dent out. Event a very slight dent can create a lot of work filler-wise and there is a strong chance the panel won't be the factory shape when you are done (as the dent will result in a new high point created somewhere, then everything is brought up to that new high point... but the panel shouldn't be that high if that makes sense).  So you've filled and primed the panel and it is flat, why would you go back and remove the primer and add more filler?

      Something else I have been faffing with while the car was off the road is making the AC work. Assuming the car isn't at a thermal limit the idea of having AC while waiting in line to go on track sounds delightful. I have actually been lugging around the weight of the entire system since 2018 when the RB25NEO went in without it working at all.  The main reason was in the first few events before I got around to re-gassing it the rubber hose that runs under the manifold had the factory heat wrap/sleeve fail resulting in this: ~2 years ago I purchased a complete used R32 AC line set but when I finally went to install it the line i needed was different where the expansion section is I found a local place that was able to replace the rubber section and re-crimp. They also added some modern heat sleeve to the hose Tight fit but fingers crossed this is the last physical piece of the puzzle needed

      the top black section is bonded to the silver section with some form of rubber. I assume to isolated NVH from the box
