Yes many wonder and think we are cheating, and well yes we are. I thought to disclose some of our secrets of our zed tt race car and why it goes so well. Yes Nissan make some things universal to different family of cars and engines as we have found over the years of checking. My zed actually has quite a few GTS-T and GTR bits including.

Nismo GTR bushes in diff and control arms. Nismo don't make much for zeds adn don't even know that some GTR bits fit zeds as not listed in their catalogue.

R32 GTR Cusco upper rear adjustable control arms. A bit heavy though soon to go chromolly custom.

Modified NISMO R200 R32 GTR diff centre with R32 GTS-4 crown and pinion 4.375 ratio. About 20 kilos lighter, much better ratio than the heavy zed 3.7 which is also a slushy viscous coupling.

Tomei GTR solid lifters, valve springs, retainers and shims. converted from hydraulic lifters similar to RB20 and 25. Solid lifters seat better at higher rpm and accommodate custom cams.

Turbo's are similar to N1 but are actually new 200SX S15 ball bearing.

Soon to have N1 silicon crank and cam seals, yes VG and RB same here and N1 stand more punishment with heat I guess and are orange in colour.

Did have R32 GTR water pump pulley with holes drilled to suit 300ZX 4 stud viscous fan. Being larger but same offset and belt size, this slowed the water pump down so it did not cavitate as much at high revs. I now use electric water pump and thermo fan.

Motor going back in next week with R33 GTS-T lighter alloy power steering pump rather than heavy zed NA cast iron one I have been using. Yes thanks to Nissan bolts straight up other than high pressure hose so getting this moded to suit.

Nismo R33 GTS-T gear box mount. New alloy light weight body rather than steel factory one, and is also stiffer for better throttle response and less energy loss.

Nismo 555cc RB20 top feed injectors with custom fuel rail that sits above factory plenum instead of below the plenum. Instead of factory side feed. Also was able to use custom alloy high flow fuel rail, and open up engine for better cooling as it keeps the fuel rail out and away from hot engine block and heads. Plus as a bonus the injectors were incorrectly ordered by a customer a few years back and I thought may as well use them.

R33 GTR accelerator peddle which has a bulge at bottom for heal toe. No GTS-T's don't have and YES GTR peddle also goes straight on and only about $15 from memory.

I am sure this is not the end of it and it does seem to keep happening.

Lots of other parts fit such as R32 or R33 GTR brakes but went 6 piston.

Zed and R32 GTR have same gear box by they way. As in the middle bit with the gears that is. Lots of other bits I won't go into here. I have only listed what is better for zed.

Not sure what Zed bits a GTR would want other than AFM and motor.

OK who's first Skylines Rule etc etc.

Bottom end is built and the rest of the motor is going back together over next week, then she goes in. Did a few mods such as custom cams with 10 degrees more lift, extrusion honed the factory exhaust manifolds and did some match porting and a few other things. It has a big SKYLINESAUSTRALIA sticker on the back maybe a GTR sticker on the front hey?

Duncan how is your GTR going and are you coming to our track day for the big GTR v ZED challenge?

Ummmm I think my Skyline has something from a Zed... Ummmm Ummmm , let me think.

Oh Yeah - I remember.........

The Nissan Badge.

JP I don't know why you go to all the trouble of making your VG more like an RB - just put the RB26 DETT in it and be done with it mate. Will save you heaps of the R&D you are doing that prooves RBs are superior to VGs and VQs.

:cheers: he he ;)

Well there have been a few conversions to RB26 into Zeds which is backwards wondering if anyone would go the other way. Big prob is the 4 wd set up.

The new generation ALLOY block VQ30 is the way to go which many of the Jap GTR GT500 Circuit cars are using.

pfft don't worry about the small VQ30 go straight for the big block VQ35 ;)

They are expensive and hard to get but looking into stroking the VQ30 to VQ35. Getting info from Nissan re this, probably same block just different sleave, pistons and rods. We will be getting ARGO rods anyway and forged pistons so no biggy there. 100 kilos lighter with more HP and torque and maybe two Disco Potatoes and wacko probably 450rwkw with out too much lag. The new Nissan range is strong, nicley balanced and not only much lighter but much lighter rotating mass. We pulled appart a VQ30 NA that we are using as a jig and as a test we weighed the scond hand pistons and rods together, not cleaned so had some carbon and oil, the maximum variations was .5 of a gram. To give you an idea this is one small posted note. That is VERY good. A workshop near us was rebuilding a 350 Chev V8 boat anchor Commodore motor and just pistons alone were 8 grams difference and they were new.

Also has R34 GTR rims on it thanks to Steve at Just Jap which we used at Drift Nationals. They realy suit the car and the GTR badge on the centre caps look the part. We actually used a VQ30 all alloy power steering pump on it. Not sure if I mentioned but it also has R32 GTR Nismo diff mounting bushes.

I imagine you have passed a casual eye over this animal...Autech Tsukada Z32, basically VQ35 with HKS 3037. I like the idea of twin GT28s better.

Hope UAS go thru with it, when i win Powerball ill pay for the container over to Japan with some Aussie built cars, could even perhaps surprise a few ppl

      Blue slip

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.

      Ethanol Content Sensor - Always at 11%?

      By GTSBoy · Posted

      The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.

      No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
