Hey guys,

I'm interested in various people's opinions on the ultimate set up for the 'standard GTR' track day class.

Drawing your attention to:

Standard Class:

(List of Free Mods allowed in standard class)

Suspension - All

Brakes - All

Electronics (ECU, Boost Controllers) - All

Intercoolers - All

Pods

Wheels Sizes

Modified Classes:

(Any of these Mods will put you into modified class)

- R Spec Tyres / Slicks under a UTQG rating of 100 tread wear (not including 100)

- A Roll Cage

- A stripped interior. Removal of rear seats only is allowed.

- Any other major weight reduction such as fibreglass doors or perspects windows

- Fuel Systems - Any two out of the following four modifications to either: 1.Injectors, 2.Fuel Pump, 3.Non Nissan OEM Turbo's, or 4.A fuel pressure modification will put you into modified class. (I.E - Only one fuel system mod is allowed)

- Non OEM Engine Capacities (GTST with RB26, RB30; GTR with 2.8L, etc)

(GTR Standard Class)

Any of these turbo's are considered a standard spec replacement turbo and are not considered a turbo mod.

R32, R33, R34 N1's, HKS GT-SS's, Garrett GT2860r-7.

My guess is that you would choose the turbos with the most low down response / linear power delivery, that max out close to the limit of the standard injectors combined with an upgraded fuel pump (approx 280RwKw?)... ie standard R34 turbos??

Not much need to replace the standard cooler at this level of tune I'd imagine. And not much need to get an electronic boost controller, just remove the brass boost restrictor?

Ok the first question; how big is the budget?

You will get a heap of different responses here, it really is a can of worms you've opened. For example i have a built RB2630 with HKS GT-RS's, love everything about it. I dislike -7's. Someone else may love -7's but dislike RB30's and/or GT-RS's :P

I've got Falken RT 615 semi slicks, braided lines, ferodo pads, new clutch, hard pipe kit, 6K worth of suspension mods.

Couple of issues I wanted to generate some discussion on. Ie choosing a good setup... within the mentioned rules.

GTRS's are not allowed, you have to choose the turbo from the list. But what is the point in going for a larger turbo like the gt SS or garret 2860-7's when you are limited by fuel Supply? The rules say you are only allowed one fuel mod. Ie either injectors OR fuel pump. I figure the most you can safely get would be around 280rwkw by upgrading the pump.

I figure power FC, fuel pump, R34 GTR turbos would be a good combo within these prescribed rules.

Other opinions?

Slimjd - in the interest of sportsmanship, you dont cheat. Its a club motorsport class.

Anyway... you could always just ask SAU-Vic members who are currently in, or have been in, that class... being its the Vic Motorsport class your talking about :P

Some of them have been going around in circles for a few years and probably already have a pretty good idea of what makes a GTR fast in Standard Class.

If you understand GTR's Luke, you can get to 330rwkw easily within the restrictions, however can you use that much power on street rubber and be fast? :)

Being you are on street tyres, you are better off getting suspension and brakes, complemented with the best tyres you can buy rather than chasing the power... that would come 2nd being you need to get used to the car for a season or two anyhow. You'll want to consider turbos as well. Pushing GTR turbos (stock ones) @ the track is a very bad idea. Less emphasis on the power either way.

Good advice there. you need to stop dispensing so much of it, poor young thing i am, theres only so much awe i can produce :banana: lol i kid i kid...sounds good though.

So i'm gonna say. yeah. what he said ^

Thanks for the great advice guys.

Had my first track day at Sandown a few weeks ago and loved it (apart from hitting 180km speed limiter half straight). Definately keen just to enjoy my car in its current light tune for the moment, and improve my driving.

In the future though, sounds like a new stock fuel pump, injectors, 2860-7's, and power FC would be a good combo.

Direct deposited my skyline club membership fee today, hopefully can still sign up for the winton track day in early July!

Anyone else going?...

Cheers,

Luke.

      When you crank your car, and hit it with a timing light, can you see a steady crank timing?

      Oh, forgot to add, A few months ago I was getting mixture codes and the car was using crap loads of fuel. You could smell the unburned fuel in the exhaust, it was crazy strong. Economy was over 17.5 l/100 and usually around 19. I smoked the engine and found a leaky CCV hose which I replaced and then I replaced my two pre cat O2 sensors, I also replaced the MAF. This fixed my mixture codes and improved my exonomy but I'm still 14 - 15 l/100 when pottering about town so something is still amiss. Throttle response is much better and it has more pep but I'd like to know why it's still so thirsty (and I'm hoping that whatever it is gives me a bit more poke).

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Hello all, currently finishing up a rb25 swap into my s14. Having issues with starting, car has spark (confirmed by pulling a plug and watching it spark), has fuel(confirmed by checking pulse/voltage at injectors all spark plugs are soaked in fuel). Car cranks over and pops into the exhaust with a heavy fuel smell but no attempt to start or run, I have torn the timing cover off and triple confirmed timing, turned the CAS in multiple spots both directions, attempted to start with coolant temp and maf unplugged, checked my fuel lines and made sure they weren’t backwards, checked voltage at cas/injectors/coilpacks, made sure all the grounds in the harness are connected and added a few grounding straps (1 from chassis to block, 1 from chassis to head, and 1 from chassis to igniter chip) I am getting stumped here. As a last ditch effort I made a full grounding harness tonight that’s going to run from the battery and add an extra ground from the battery onto the coil pack harness/igniter chip/ intake manifold/ Wiring specialties harness ground/ and alternator. I’m hoping maybe the grounding harness will fix it here but posting here to see if anyone has any other ideas on what else I can check. My fuel pressure is unknown right gauge will be here tomorrow.  IMG_3206.mov

      yeah I was shocked when I checked my spare OEM on and as below that's how they come from Nissan. (side interesting note new NEO gearbox and replacement park lack the brass bush on the tips and its just all alloy) unsure about damage to the box currently back at 1110 to be pulled down/inspected and selector fork replaced as he built it previously and given the never before seen failure on his billet forks he is replacing it under warranty. He said he has used always OEM the keyway tab without issue for years so it could be an unlucky coincidence. I did talk to him about the sharp corners and stress concentration too. Re: hard shifts i got 7+ years out of the OEM one and the fork itself failed not the keyway. so could be bad luck as I said or an age thing + heat cycles in box and during fabrication of billet?
