Looking For Gtr Group A Specs

Hey folks,

I have done a bit of googling and dug around the site a bit and found some great information, however I'm specifically looking for details of GRP A spec GT-R's (either 32 33 or 34) as a preliminary to rebuilding my car.

Dont get me wrong, my car is clean and steetable, my plan was for my GTR to haul my carcass around daily for a few years before I join the 911 club, sure flame away if you wish, the point is I'll keep my skyline and rebuild it to some form of GRP A'ish specifications for tarmac rally and track use.

I'd like to keep the car regestered if possible (maybe a long shot) but the car will likely not see road use again, altho I would like it to be possible to bring it back to road leagal if required, so not an all out seam welded stripped out monster :D

I have worked as a fitter and turner in the motorsport field when I was younger and have a workshop at my disposal so some of the build I will be able to do myself.

the car may not come off the road for another 18-24 months yet, but it will ease the finantial pain of it all to be well prepared and have a plan on where I end up with the car. obviously it will need to meet CAMS regulations (which class's I have NFI at the moment)

So I ask of you any links, files or the like of GTR specifications for GRP A or similar class you may be able to help with. Indeed any words of wisdom or advise reguarding my plans as it isnt the usual GTR mod path.

any help or advise greatly appreciated

Cheers

Just remember that the Group A cars are now over 16 years old...and terchnology has come a long way since then. Also, the Group A cars were built in line with rules and regulations...it doesnt sound like your car will be built to a class so you wont be limited by the mods the Grp A cars ran.

Mod away to your heart is content. Oh, and maybe consider buying a not so neat example if you are ust going to turn it into a weekend race car...no point wasting a good daily driver.

Have a look in the motorsport section there are some good threads about building a circuit GTR and regulations for gtr racing.

If CAMS is a priority for you there are only 2 classes a GTR is eligible for.

3e - production - standard cars, no mods except suspension and ecu. I have a 3e race car. no 3e series in Vic

3J - improved production - allow quite a few freedoms but the big issue is all turbo cars have to run restrictors. there is 1 3j GTR in NSW which has had some success with a lot of development, but it has a very hard time against the RX7s (much lighter and similar power)

well the grp A specs was just as much for a good read as ideas to implement with my build, I cirtainly wont be using dated technology.

now Duncan has me pondering what to do about CAMS...

hmmm

perhaps I'll forget about CAMS and just build it and let scrutineers decide on which class it falls into for events such as targa tassie and the dutton rally which i'm more interested in than season racing.

that said grp A is where the gtr came from so it makes sence to use the specs as a reference.

Doesn't the old Gibson Racing Team Engineer (some guy with a german sounding name) now run his own Performance Shop in Melbourne (Hyperdrive, Hypertec, Hypersomething....??)

I am certain he would know about the Group A specs.

That's Eric (forgot how to spell his surname), he used to work at Hypertech, now he's working at Kamikaze motors from what somebody posted on this forum. I could be wrong but never hurt to search this forum for posts.

my advice, decide what you are going to do with the car first. Second, read the rules for that over and over again until you understand them and know them inside out, before you pick up the spanners.

you obviously need to be registered for Targa or Dutton rallies. Targa has strict rules on mods for modern competition, whereas Dutton is a "run-what-you-brung" sort of affair, but very expensive for a multi day Touring Road Event.

yes I cirtainly will be very carefull before doing anything major, my idea for the car is to enhance it in the spirit of the type of racing the GTR was designed for rathur than rice it up with bolt on mods

As I have a workshop available and having worked for hollinger and modena engineering in the past I plan to make quite a few of the parts myself.

That said I'm giving myself plenty of time before I actully do anything, and am considering doing a r32 gtst drift car in the interim to learn my way around the car before getting serious with the GTR, and because the spares I have left over can go into the gtst.

just need to work out how to justify a hoist to the tax man :woot:

      Actually, that's not entirely true. It's also the same motor in the 1st gen Nissan Cube but they're rare as hen's teeth.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By Duncan · Posted

      Yeah it is always worth testing and balancing actuators out of the box, just set the pressure regulator on a compressor very low (eg 5 psi) and increase it slowly to see when they both move.....unfortunately while you may be able to adjust the length of the actuator rod to minimise any difference, the actual pressure they move from is not adjustable so you need a well matched pair. And yes, the VCAM is probably contributing; the earlier in the rev range they come on boost and the slower the revs build (I think your demo was in 5th), the more you notice it.  Driving at WOT through 1st, 2nd, 3rd etc you will probably never hear it as any shuffling starts and is over super quickly

      oh they were with that motor, you need to remove the engine to change the spark plugs (don't have to, but it does make it easier)

      I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly

      I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
