Roy, UAS track days are for everyone. I have been accused of over favouring GTR's in the past, this was from a few of the zed guys. This was because we had 12 GTR's at the track one time and they get their own sessions along with race cars.

This day will sort out the men from the boys. I would not speak too soon as I have a good customer Gary who has owned a heap of GTR's, and is very experienced at the track. He has also done quite a few Targa's. He was the guy who drove the white N1 set up R33 GTR a few years back that ended up a tree, and him in hospital. The following year he wrote off another R32 GTR, head on into a tree. He is a good driver but has a big go. This year he is not doing Targa and put his effort into beat me at this track day. He has accumulated lots of good bits out of his 3 R32 GTR's and put them into one to make an awesome track car. Featuring Holinger sequential gear box which is good for at least a second a lap. He say more like 2. Big motor with 2540's and forged internals etc and 350kw at all 4. Stripped out with cage, big brakes etc. He is not beer talk. Will be very interesting. His fastest time was 106 .95 with the sequential box in the R33 N1 GTR. His new current race R32 GTR should do better than this. It will need to.

Tosh ( SW20 ) was over today and has has seen what we are doing. Last year the Zed was stadard internals and not too many mods but now it is full on now. We are running S15 turbos in the "Franken Zed "which are same HP rating as N1 spec so still can compare I guess, but yes lots of other things. It is again getting more like a GTR as now has Tomei RB26 solid lifters to add to the GTR bits in it.

I might Add Geoff from SSS Automotive will be out in his Gibson powered R32 GTR and has done more mods including better brakes and gear box, and will be in there. Joe also from SSS Automotive might be there with his well over 400kw at wheels R32 GTR. Power is not everything though.

Will surely be a great day John and a great opportunity to see some awesome machines in full flight.....

I'll be there sometime through the afternoon to come for some laps :P

p.s. As John mentioned I was out there yesterday and DAMN is he going to some major measures to lighten the car!

    • Don't even try to run it on the stock ECU if you're going to have the boost controller bring boost above ~10 psi. I've already told you that. If you use the Nistune ECU, you will need to CAREFULLY read the available documentation for Neo tuning, and read some threads on the Nistune forums, to discover the various things you have to do to prevent the ECU from going bananas when the boost is too high. The is a table associated with th boost sensor that must be modified to prevent it from shitting the bed. This is just one of the things that you will need to do to the tune in Nistune, because the Neo turbo ECU will be expecting to see a number of things (such as the TCS) that are not there, and you have to block the DTCs on those. It is totally not surprising to me that you are having the problems that you are, but the solutions to these problems have been known for >15 years. So just get it done.
    • Hi. Sry iam not a mechanic and iam not at the car atm so i dont know 100% but they told they measure those and even try to change those. AFM they have two. Coils are new a they have my old one too. Plugs too. ECU...we have 25 NEO stock and Nistune 25 NEO.   But i dont know if any one those could be the problem and why/if/what can cause this, Only thing they did not check is fuel...but that walbro 255 is new(like 1,5 years)... That fuel pressure gauge idk...but i let them know Any suggestions?   EDIT: how can they know if it is like you say he ECU pull power when it reaches a specific boost level that is too high? Tha car has boost controler
    • Can you clarify what you mean by boost cut, do you mean it misfires both when under load (driving) and when stationary and out of gear? Or does the ECU pull power when it reaches a specific boost level that is too high (boost control issue)? Does it occur at idle with no throttle? When you say "the ECU is OK", what ECU is it and why do you think it is OK? Have you used the NEO ECU, and if so do you have a MAP sensor attached? Same for the AFM, why do you think it is OK? Do you have any way to put a fuel pressure gauge on it (even just a mechanical one between the fuel filter and fuel rail)?
    • Hi.. Just another problem. So maybe you can help. I(my mechanic) done swap from my RB20DE NEO to RB25DET NEO. Everything is OK but we have a boost cut. Coils/Plugs are ok...AFM is ok. ECU is ok. I have Walbro 255 but it "changed" sound few months ago(you can hear it ouside) you did not hear that when it was new(maybe faulty?) Sooo...what now? What can cause this boost cut? It is even when you standing still...
