Have asked the same question myself a few times. There appears to be a few of us GTS owners who participate in this forum. Pretty handy to learn from the 'big' guys in their GTRs. Haven't found any GTS clubs just nissan turbo etc.
From what I've read, we can participate in the forums etc but obviously can't join the GTR register.
Nice one as it would be good to meet up with fellow owners, and seeing as Oulton park is 5mins away even better.
Also anyone out there done any good mods to the GTS-T and got good results? Have some cash spare and was wondering which mod was the best for the cash? Also what sort of power increase can u see with the RB25DET (Whats the max some one has got then?
Just fitted a fuel cut defencer chip and HKS boost controller. That's boosted me up to 282bhp at 0.8 bar. Was gonna give the fuel cut defencer a miss but without it my standard ECU was only good to slightly above 0.5 bar (standard is 0.45 bar).
Had thought of fitting a cold air induction kit but when it was tried out it was sucking 'hotter' air than the standard air box so dumped that idea.
Even with this small boost in BHP see a very noticeable difference in performance. Don't forget to fill your baby up with Superunleaded. The guys here have been very helpful with info etc.
FCD are a waste of time on the RB25DET. Speak to Ian at Hi-Tek and he'll tell you why. I know of another tuner who's tested the thing and said it was useless - apparently they only work well on Toyota engines and hence their popularity with the Supra boys.
I took your advice and wasn't going to get an FCD fitted but when the chaps at Scole tested the set-up with the boost controller and normal ECU, the ECU was only good to just above 0.5bar - hence fitted the FCD. For the sake of £95 it aint make of a sacrifice
It's just that I've been told that if you boost over 0.8 bar and use an FCD to aid fuelling then that's when you'll experience the problems. Unlike the GT-R, the stock ECU for the GTS25-T doesn't have maps for anything above that boost setting 'cos of the higher compression ratio.
Scole tested my car at 1.0bar and had to stop due to detonation. It appears that I'd have to get a bigger intercooler to run at that pressure. Did get to me above 300bhp though! From all Ive read at these sites it would seem that the next mods would be more extreme - bigger intercooler, metal head gasket, metal turbos?, remapped ecu? Rich probably worth taking all this on board.
As I said above, despite the discussions we had earlier about the standard ECU being good to 0.8bar, the reality was far from it.
Well to be honest Stu, I'm just relaying information that was told to me by a friend in Japan who had his car tuned by HKS Hiroshima.
It may well be that it'll run ok at 1.0 bar with the stock ECU but then you'll be risking engine damage. I am far from an expert on this matter but I've been told that Nissan didn't have maps for anything over 0.9 bar and thus would shutdown if it tried to go over that figure because it didn't want to damage the engine - the FCD would get rid of this facility and hence you'd have 0.8 bar fuelling at 1.0 bar boost - Ian at Hitek will explain it better.
GT-R's are different, you could increase the boost, adjust the timing and away you go.
But intercooler, ECU and head gasket would be a good move for your next mods.
