hey all i just had my r32 dynoed at hyperdrive, when i bought it i was told it had about 299rwhp with a miss, i wasnt sure so i took it to hyperdrive this mourning with spitfire coils and only pulled 265.9rwhp at 14psi, the boost was all over the place, the guy at hyperdrive told me the hks 2540 wont really do anybetter than that :D so anyway im gonna get a new turbo, any suggestions where to take it or what turbo to get??

cheers

i recommend the HKS GT-RS i think brand new from www.greenline.jp is 2.5k give or take...i've been in [Michael]s car and damn its responsive and powerful hahah or even the Trust TD06-25g or 20g but i would go the HKS because its coolant and oil cooled the Trust turbos are only oil cooled also the Garret GT30 series they good to hehe :D

Nothing wrong with the 2540. As people have said it will net upto 350 or so and will run 18psi.

What ecu are you running on the Rb25?

hks evc waste gate controller

spitfire coils

new ngk plugs

k&n pod filter

z32 afm

aluminium fmic

3.5inch jap exhaust with apexi muffler

Your setup will make a very easy 350rwhp if it really is a 2540.

Topracing is open this coming Monday but as we closed for 3 weeks the backlog is quite big so best ring John about booking anything.Its the time of the year we build new racecars and refresh/upgrade the current ones so it may be tough to get in for anything other than small jobs.

Damn you're only making 20hp more than me and all I've got is a stock 25 turbo! same dyno too.

I've got a GT35R with a .82 rear housing waiting to go on my engine.. I reckon it should chirp 2nd :blink: would suggest either a GT35R with the smaller .63 housing or a GT30 for your engine. Pick a hp goal and have a read through the 25 turbo upgrade in the FI area.

so do you think it is just a case of upping the boost and retune?

wow is that all.. i'd be pretty pissed at tha guy who sold u it huh!!!

i'd feel sorry for u =P i got 268hp @ 10psi stock everything nearly!!

got a new engine since =P hyperdrive have gotta do my timing its 15o out =/

    • 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...
