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?
