Creating A Dedicated Track Gtr

[Duncan]

Well, as you may know our race car runs in production cars, ie we can't do anything to it except standard parts.

Which got me thinking......

If you were building a dedicated circuit GTR, not to any CAMS regs, what would you do?

And please don't bother with "build a carbonfibre body and drop in a mines crate motor"....I mean realistic

[blk180]

STAGE 1

1. Strip all insides out and cage it

2. built buttom end rods, pistons,high volume oil pump, 9 lt sump, head to block drilled out, oil return from head to sump,ATI balancer and light weight pullys, JB clutch.

3. HKS 2530s ,cams, Trust front dumps and hard intercooler piping kit or TO4Z kit

4. power fc and nismo AFM(Z32 if TO4Z)

5. sydkid sus set up

6. UAS light weight tail shaft

7. fuel system to suit

8. remove air con and HICAS

9. new braided(spelling) brake lines

10. Trust TI 4in exhurst no cat

11. Run whatever rims came with car with sticky tyres(RE55)

12. Big ass cooling system

Most liky all i would do untill i had run the car and seen what i wanted next

Stage 2

1. Big Brakes 6pot front, 4 pot back

2. Cross misson or dog box depending on what the buget will take

3. new front and rear LSDs

4. Light weight 18in rims to clear the new brakes

5. Rebuild transfer case

Im sure there would be lots of other things but cant think of anything else now. I like the TO4Z. That would be a buget Car i would build. All comes down to how much money we have to spend.

EDIT: mostlikey added a vented CF bonnet and a computer with data logging insead of the power FC

Give Ben at Racepace lots of $ and a GTR and ask him to make it go fast

why? because i don't know shit about cars

[88silhouette]

easy

sell the gtr

buy hr31 coupe

then get cracking with building a 31 track car

[Duncan]

hahah thanks mate but I would prefer double wishbones all around, not to mention 4wd

blk180 looks like you have had a quick think abou this too

how big is a to4z, isn't that a single? I was thinking 400kw+ would be handy.

nice adjustable suspension arms all around too....maybe Gary's suspension kit but I reckon a set of nice DMS shocks might be better suited.

[blk180]

Yer have had plenty of time to think about it but like most of us its just never going to happen but my daily is getting to point where it can be tracked bashed but not striped, no cage and only has 2530s.

HKS say there R34 makes 468kws with there TO4Z, 2.8lt kit and Vcam.

TO4Z is single high mount and the garret one will still pull 400+rwkws.

rb30 bottom end with a t04z, just built one for a friend it reaches full boost by 3100rpm and revs all the way to 7600 with standard cams and makes a tidy 370kw atw on only 18psi yet is very tackable and has huge amounts of low down torque. I would run a dry sump setup also and try to get 285+ size tires under the thing. Along with the other stuff people have mentioned in terms of weight and cage etc etc. That would make a killer track car!!

[Duncan]

hmm sounds nice....reckon you could run another bar of boost to get some more power out of it?

[Roy]

Whats realistic? Basically Kennys R33 GTR (before he popped the engine ) is about as far as i think is practical...any more and you would have to have some serious coin

So what budget is realistic?

[giant]

i reckon about 50 or sixty grand

[Ronin 09]

bin the GTR and start with something lighter... i want an MX-5

[nedi]

i've just acquired a tough built race engine - rb26 head on rb30 bottom, to4z (single) ready to go on along with most of the stuff the rest of ya mentioned. including full cage and some race buckets and grex alcon 6 potters. I will have dry-sump set-up to be safe.

i using motec so i can clear much needed space in engine bay--ie no air flow meters, new minimal wiring loom, all the standard crap/solenoids/pumps/vacuums etc bolted under and around plenum and everywhere else to go, battery to go behind the seats.

i have removed hiccas and will run standard box till it breaks then upgrade to PAR dog box.

should be thrashen it around at vic race tracks by october or november. and will also contest in gt sports series. i'm told it will qualify for this.

currently doing 1min 21.2 secs in standard porche gt3(385 horsepower at flywheel) at sandown so i can steer allright. i let you all know how the set-up goes but my times will speak for the set-up more than anything.

similar set-up by a sam mirkov in a white r32 sees him around sandown in 1min 15secs(on par with gt3 cup cars) which is dam quick so i hope to get a little faster than this.

i reckon whole set-up will cost close to 40k including car(mine cannot be registered-race use only) you need to be savvy, and take some risks with second hand stuff and utilise e-bay and forums. Buying engine already done will save you thousands but be sure to pull it apart and check it to be on safe side even if it does cost a little more to do.

good to see somebody with the balls to circuit race a car.. everyone else seems to be drag racing only

good luck nedi, the gt series is pretty damn quick, it would be good to see you out there! I would be very sure everything is legal there are some pretty strict regs or at least lots of special rules for certain cars....

giant.....what are you happiest about and what would you change? you would have to have the quickest circuit car on SAU

[phunky_monkey]

Nedi, are you the guy that drives the GT3 RS with the PCV??

Cool...though 40k would be doign a lot of the work yourself?

Any times for PI or Winton in the Porka...im hoping ot get into the high 1:22s in my R32 GTST, curious to know how quick the Porka is at other Vic tracks

[giant]

hmmm i reckon i am happiest about how much fun it is to drive! such a sweet engine when they are sorted. and a lot of satisfaction in sorting the car with different issues and knowing is faster as a result.

i am most unhappy about the weight they lug around!!

what i need to change is rear brakes, absolute shite

four pot a.p's next month hopefully

dunc the controller is still going strong too, great bit of kit

heading to dutton N.S.W Thursday morn

cheers Russ

[fatz]

id take your 3 litre gtr motor witha t04z

and whack it in my silvia

and give the gtr's abit of what for

[KamikazeR33]

t88 33d, nagisa auto gtr utilises it quite well

[nonalcoholicrwd]

currently doing 1min 21.2 secs in standard porche gt3(385 horsepower at flywheel) at sandown

wasn't that a GT3-RS ?

[Roy]

LOL...dont forget to throw some serious coin at it for a close ratio box.

If only GTRs were built in the 70s without all the electro crap and safey gear that modern cars are built with, they would be half a chance of beign a bit lighter. Cars these days are even heavier so
