Looking For Gtr Group A Specs

[Betz]

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

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

Speak to BEN at Racepace, i'm sure he can build your GTR to a better spec than just group A.

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.

[Count Grantleyish]

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
