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

      R35 GT-R production ends after 18 years

      By Rezz · Posted

      Order for the 2025 model R35 GT-R were accepted from 3rd March and 26th August the last order rolled off the production line at the Tochigi plant. Concerning the R35 GT-R replacement, current Nissan CEO Ivan Espinosa said "Nothing has been decided about the GT-R at this time, but we are well aware that everyone is waiting. The GT-R will evolve and reappear in the future. Please be patient until that day comes." Nissan has a lot of issues with management and finances so take Espinosa's words with a big grain of salt. From what discussions I've had and read about here in Japan, not a lot of people are confident about Nissan's future, let alone the next GT-R.

      R34 25GT Engine Light 21

      By MBS206 · Posted

      21 is explicitly the coils detected as the issue. Is it guaranteed the actual issue? No. Just the ECU thinks it is. When you say rattling, describe it better, get an audio clip as best you can if possible.

      Yea got me coppers. Bad news is I just put them in and the car still has the light and shakes. I also noticed I hear like rattling coming from the exhaust piping right under me. Does 21 also have a possibility of being O2 sensors?   So, coil packs are good, the harness is good, the MAF is working, and obviously the spark plugs just replaced and working.

      RB25DE NEO with Haltech ECU

      By MBS206 · Posted

      Make sure you drop the GTT base tune back in, and set your injectors again, this will remove anything playing up with it you may have removed. Possibly lean there as it's normally a fast transient going THROUGH atmospheric pressure, and a turbo motor would then quickly go richer as boost builds. The only worry you MIGHT have is ignition timing, as the DE is higher compression than the DET from memory. But again, you're not in boost, so the DE motor will be a lot more forgiving at atmospheric.   Get Murray, Kinkstahs, and Johnny's input on tuning haltechs, those guys have played with tuning enough in the past to be able to help now you're past the trouble shooting stage of the MAP issue
