Hey, yeh pretty much all sorted now. Haven't had a compression test done but she makes around the 400hp mark now which is good. Been ages since I've posted in this thread, can't remember if I updated

I don't use the hand brake to launch so these are without handbrake

5500-6000rpm is minimum to get a good launch with stock turbos, 6500-7000 for -7s is what worked in the 34 so the guy ( sorry I forgot who it was ) that said 7000rpm for -9s is on the money, you just have to ride the clutch like you paid for the full hour and you intend on enjoying every minute

drive it like you stole it, service it like you love it

Well I've cranked my stockers up to 18 pounds not too long ago and it would've been the most violent thing I've ever driven....took some mates with and they too were very impressed! It was very, very troquey down low and pull all the way thru till redline in 1st and 2nd....but in the remaining gears they weren't too crash hot.

The only thing I've been wondering about is how yours fair down the straight in the higher gears?

124mph on GT-SSs ? I have run back to back 125+mph on stock turbos in a full weight car(+ 2 amps )so why would GT-SSs only run 124?

R33 GTR - heavier :D

Everyone i know with -9s hasn't run better than 124mph on PULP in a 33R

Oh actually 380rwkw man has a R32 so it would be higher by a few - but it still won't be anywhere near 130mph, which it will need to be to back 380rwkw

125mph over a standing 1/4 is how it goes in the taller gears :yes: , it has also seen 240kmph+ by the end of EC main straight,

ride clutch, it should be a progression not just a step, stepping will break drive line at 7000rpm, the key is to load the drive line then progressively lift foot off clutch pedal and hold on. :thumbsup:

are yes 33s are very fat, and I don't mean PHAT, lol :nyaanyaa: , even so given 125 with 290rwkw, a genuine 380rwkw I would think should see more then 130, then that's in a 32

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that

      S1 rb25/s14 starting problem

      By MBS206 · Posted

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
