Awesome mate I'm happy too lol sooo tidy. Can I ask what the deal is with g sensor awd mods ? What are the benefits of the ecu ?

More info here http://www.full-race.com/store/r14-awd-skyline/ets-pro-center-diff-torque-split-controller-for-r32-r33-r34-skyline-gt-r-1.html

Looks great Simon! When does it hit the dyno?

Soon fingers crossed, whenever I can get Sean to do it

New motor in and going with the Tomei Poncams (Type R) 250 x 9.1mm Went 590hp at 1.5bar and 670hp with 1.9bar. Didn't bother pushing any harder as I just want to see it's all good until I push it a b

Well GTR ownership is getting expensively depressing. Quaife ATB which has finally arrived this week and is being installed on the 6th of Jan. Rear diff has been rebuilt and tightened so it's

Finally back and running, the alignment got a bit stuffed up and they put toe out on the rear instead of in which made it interesting with delaminating tyres on the rear

Nice work mate, looking good!

When you relocated the battery to the boot, did you use a kit or just a variety of off-the-shelf parts? Looks very fancy! :)

Just bought the wire, terminals and a billet bracket (that's meant to be for an evo) and made it up as I went along. Happy with the way it turned out, nice and neat :)

Ran the lines for the oil catch can today!

I will print one out next time I'm down at Allstar. I just did a quick comparo

3500

GTR = 100 Gts-t = 130 (-30)

4000

GTR = 175 Gts-t = 200 (-25)

4500

GTR = 310 Gts-t = 225 (+85)

5000

GTR = 460 Gts-t = 425 (+35)

5500

GTR = 520 Gts-t = 485 (+35)

6000

GTR = 560 Gts-t = 520 (+40)

and so on holding about an extra 40hp top end...

Not really fair because the Gts-t run started at 2000rpm while GTR ramped at 3000rpm, if all was equal I think the GTR wouldn't have given any power away at 3500-4000rpm. Plus the Green car was running a fair wack more boost.

Finally got my ass into gear, purchased some Advan 050's and got down to No Limits at Barbagallo Raceway last night.


I have to say that this GTR is infinitely better to drive than my old Green Gts-t, the Gts-t felt like you were flipping a coin to see if it was going to kill you every time you hit the brakes or the accelerator. This GTR is very nice to drive even with the lack of development and set up, so much more confidence!


Had a few issues, hit boost cut 11 times on the first two laps (1.74bar) so RRob pulled the boost right back to 1.1bar for the night.


Long track was just getting a handle on the car but ended up getting fairly fast by the last session. Short track I only got 3 laps in before calling it a night but was fairly quick straight off the bat. I went to the night hoping to scrape into the 64's long track and 55's short track which I thought would be a decent result for first real outing. Ended up going 64.2 long track and a 54.4 short track so much better than planned. Was stoked with my times, now resetting my goals now and keen to get back out there again.


To give you some idea of times, I would have qualified 2nd in Street Cars and Improved production class at their last meet. Not bad for what is essentially a street car with full interior and stock motor :)

Any people who track R32 GTRs want to give me some advice on front camber?

We originally set it at 3.5deg but had to raise the front coilovers which lowered it to around 3deg. Didn't have time to have another alignment before the track day so it stayed there. I know it needs more but how much? I'm thinking of going to 4deg as the next step

Well I use 3.5 degrees. But it depends on your spring rates and sway bars. Obviously the harder they are the less camber you need. Wroo tends to like neg camber due to the corners going on for ever. You take tyre temps on the night?

How did you find the Yokies under brakes with that camber on it?

Cusco Sway bars and old Tein Flex coilovers (they are not even base adjustable) so I'm guessing they will be 8kg front and 6kg rear. Have not even bothered checking the rates. No tyre temp checks on the night, I was actually running too much pressure (34psi) and have got feathering on the tread edges because of it.

Car was great under brakes, pulled up straight, quickly and easily from the 230 odd km/hr I was doing down the back straight.

Simon whats your opinion on the ets pro controller, and what made u choose this instead of ruzic.

Cheers

Pat

To be honest I set it at around half way on auto and didn't really adjust it. The car had a bit of under-steer but that was more likely to do with needing more front camber and too high tyres pressures.

It wasn't acting like a normal 32 GTR that's for sure, no tail out and then catch the slide. Just power out of the corner, gave a lot of confidence!

Looks promising and considering the times I did with lack of track time it can't be a bad thing. I'll have more of a fiddle next time I'm at the track and report back my opinion.

EDIT: Went for it over Ruzic for lots of reasons, pre-load on transfer case, more adjustable, changes easily on the fly and digital sensor.

      RB25DET with solid lifters - which cams ?

      They are under bucket shims. Tomei provides a test shim kit and then any measurement of shim required.

      RB25DET with solid lifters - which cams ?

      By GTSBoy · Posted

      I always wondered how you were supposed to buy a set of 24 buckets and somehow magically have every single one of them yield exactly the desired clearance. I would have thought you'd need to assemble a cam with either 12 "sample" or "example" buckets of known top thickness (or a single such sample/example 12 times over!!) measure clearances at every valve, and then do the usual math to work out what the actual "shimness" of each bucket needed to be, before buying the required buckets to make up he thicknesses that you didn't have on hand.

      RB25DET with solid lifters - which cams ?

      By TurboTapin · Posted

      I now seem to be limited in power due to my rev limit/hydraulic lifters in my built RB25. I'm looking into converting over to Tomei solid lifters. Question for anyone that has done the conversion. I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  I don't know where I got this idea, as so far I see no mention of this in any of the Tomei documentation. It just states I need the Tomei solid buckets, solid lifter cams and upgraded springs. As my head is already built, all I would need is another set of 1000$ Kelford cams, 500$ buckets and about 4H hours of my time installing and I'm off to the races!?!? There's no way it's that simple, I must be missing something?

      Why am I hitting a power wall with my stroked RB25?

      By TurboTapin · Posted

      I couldn't agree more. I should have started from the get-go with a NEO or solid bucket conversion. I started looking into converting over to solid lifters yesterday. Now for some reason I was always under the impression that when using the Tomei solid lifter conversion, you would also require new valves (Longer or shorter stems, I can't remember which).  But I see no mention of this on any of the Tomei documentation. It just states that I need the Tomei solid buckets, solid lifter cams and upgraded springs.
