I don't know all the ins and outs but the cheapest/easiest option would be high-flowing the gtst turbo and keeping it a single setup.

I remember seeing a similar post years ago question the convert to 2 turbos on the 2.5, the response was that you may as well change the whole engine to the 2.6L, and if you're gunna do that, may as well sell and then buy a GTR

someone on this forum converting his rb20det to twin gtr setup. has extreme amount of lag and consequently is selling it. iirc it was fullboost at 6k rpm.

way too much mucking around for something that doesnt pay off

remember you'll have to have a lot of custom exhaust and intercooler piping work done, then a lot of mucking around with expensive oil and water lines

highflow is closest thing to bolt in , a slide highflow maybe require slight modification to an oil line? (but i dont believe these are available anymore). gcg maybe 100% bolt in, someone would have to confirm, -but low lag lots of power.

edit: i was assuming you were wanting to change to a twinturbo setup, i have no idea about using only one gtr turbo :sleep:

2 gtr turbos is not bad on a 25, i have the adaptor plates and parts to do it but the problem is running the engine with 2 afm. i am tossing up between this setup (which came from an rb20dett) and a hks gtrs. 2 totally different choices.

GCG - around 1900 (ball bearing)

bush bearing - 1200ish (some guy in sydney does them, forget his name, look up the member QURIOS or something similar)

they wont take your compressor wheel either.

there is alot more into it than just that.

they'll take your housings and bore them out. their hiflow housings dont just require a bigger wheel, and their whole cartridges come pretty much complete anyway and thats where 90% of the cost is.

you need to have a cartridge to support the shaft that will be spinning 150-200% faster at full song.

1 is brand new the other is machined old parts, common sense would say that the new one is the better option.

the only 'old' parts are the exhaust and compressor housings which get acid dipped anyway. everything else in a hiflow is brand spanking new.

thanks for saying exactly what i just said but in a different way which meant the same thing..

do you forget saying 'the new one is the better option'?, implying that a hiflow is not new, and not a better option.

choose your wording carefully.

      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)?

      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...
