when i drive on low boost 14 psi the power comes on more progressive, 231 rwkws on low does not feel like 231rwkws on high with the old gcg turbo, it feels less violent coming onto boost. on high boost 21psi theres nothing under 2500 rpm where it starts making boost , if you roll out in first gear or second gear with half throttle its very tractable but as soon as it hits 3000 to 4000 rpm the car will break traction . even though the car now with gt30 is 500rpm laggier than it was with gcg turbo , what it has lost down low it more than makes up for when she hits full boost! i think the car was a lot more tractable with high flow , but i think shes alot more fun to drive now.

with the addition of cams going from 260 rwkws to 277 doesnt seem like a whole lot but the car feels like a totally different car to drive, more midrange as well as top end. i thought that the 260 atwheels felt good but 277 rwkws is awesome. i cant wait to get some nittos and go drag racing at calder! i just think that the car is a lot of fun to drive now.

I dont know what setup you have but maybe you need to look into your suspension setup. Maybe your car is too low and this is shit for hooking up. I have a datto with this exact problem....230rwkw GT30 with 0.82 and the thing is useless in the first 2 gears... and i mean useless!!! In third it will spin all the way to 160 if I want it too.....but my car is TOO low and has bad CAMBER which will all change when I get round to it (slotting read end and raising it heeps). I have a stock 180sx and this thing hooks up very very well...to the point where it will on lift off and flat shift 1st to 2nd put you back in your seat and you can feel it in your neck (kinda like a wrex take off). Whats your suspension like?

tried gtech 0 to 100 again , the best i could do was a 5.8 second , that was with 3000rpm side step the clutch feed the power in , back of a tad as wheels break loose then change gear and half to three quarter throttle and breaking traction completely from 80 to 100 km/h. got home decided to check tyre pressure and realised tyre pressure still set at clost to 45 psi from being on the dyno. will lower tyre pressure for better take off next time . surely i can at least pull a low 5 sec 0 to 100 on street tyres??? did anyone see the recent test on hoosier drag radials in the lateset zoom magazine out now. their 300rwkw soarer went from 12.4 to 11.6 quarter mile and they are only 225/50/16s!

Sorry to say but you need some serious tyres. I got Toyo RA1's and they are sensational. Before i could spin everytime in 2nd gear with my old tyres, but when these things are warm, i can get full traction in first gear.

Tried 0-100 and got 4.7 with only one run. I cant wait to hit the strip for a low 12.

more power but 0-100 times go backwards. :D

My little old RB20DET used to run 0-100 in around 5.2secs, the rb30det making slightly more power gets there in 5.9secs. :D

First gear is completely useless, the 5.9sec 0-100 is launching at 3000rpm in second. Diesel power.. :)

Time for some decent suspension?

;) cheers :)

      spot the stagea

      By AnimalGarage · Posted

      It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack.

      Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.

      In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).

      ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.

      OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
