Just a quick question, If u take off normally but then slowly boost it into the high revs 7 -8000rpm in 1st gear just to feel the boost but theres not enough road so then i put the clutch in quickly and let the engine wind down like its in nuetral, is that shocking the engine more then putting it into second gear straight away?

Summary: The revs go REALLY high in gear then then in mid or high boost take it out of gear, im just wondering if that bad for the engine?

meh its basically like reving ur engine while ur cars in neutral but ur using the gear to move the car..

i dont think ur doing damage.. but like any car sooner or later u will ware out something ... piston rings or something especially at 8000rpm...

personally i dont know why ur thrashing 1st gear to 8k rpm all the time ... ur gona blow something.

Also on that note.. i hope ur not killing 1st gear that much on our Victorian roads :D

Actually its more like 7000rpm thats the peak time of boost when i normally kick it into second, but sometimes you dont want to keep going.. so u just nuetral it. (sydney) :)

Please dont do this on the street, it makes baby jebbus cry and makes the police a bit upset to, do some track days and stuff and leave the hooning to the falcodoores.

from reading this post and a few of your others it seems you have no idea about how to drive a car, let alone a GTR.

i suggest you sell it before you hit a pole, seriously.

lol your not supposed to hit boost until the car is warmed up, let alone 1st gear 8000rpm journeys...

ahahaha, the flamers in this thread are just as bad as the OP. no infact they are worse (except terry). h said he is only mildly boosting it up to high revs. not flooring it. 2 completely different things. also not really hooning other than making noise. and even in a 50km/h zone, he wouldn't be much over the speed limit in first.

as for whether its bad or not, it wouldn't be that bad. i'd say that flooring in and boosting hard up in first to 6000rpm would be worse than light boost to 7000rpm. and i think dipping the clutch would probably be better than using using the engine to slow you down from that speed as the less time you spend at higher revs the better. however you will slow down just as quick (or maybe even quicker) with it still in gear.

personally i'd be going to 2nd, then slowing down again rather than holding 1st or dumping neutral and freewheeling it to a stop without the driveline engaged.

or rev it out in a 100km zone to ensure you are within the speedlimits.

Um yeah right.

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      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.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      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)?
