btw.. I made 164rwkw which is 221hp on 1 bar of boost.

Its not just about peak power its the mid range that gets you there so the RB25DET will be quicker in accelerating to the peak power.

Considering though the RB20DET does do extremly extremly well in the power department. Especially considering the RB25DET has VCT, bigger turbo, higher static comp ratio etc..

Just to throw some spice into the conversation, my CA18DET did 214rwhp fully tuned with an SAFC etc, and my RB20DE does 120rwhp with no tuning, no oilchange running 95RON fuel :)

its not about displacement sometimes...

Snoop, are you doing the conversion yourself? If you are then i'd honestly put about $2500 aside for things such as timing belt, fuel pump, filter, oil, sparkies etc. Second of all, you will need to do something about the sump hitting on the sway bar and the clearance of the engine ie hitting the roof. Are you good with wiring? If not then put aside about 300 at least for getting someone to do the wiring and adjusting. If you already have a sr20det then stick with it. I promise you you'll be better off.

The front cover turned out to be stock aswell, I originally thought it was a VG30 item but that would mean it would be smaller than the RB25.

The turbo is still running fine after two and a half years( with a greddy cooler which I think increases its life)

I am having it rebuilt because a friend of mine was helping me pull it to bits and snapped my turbine off the shaft with a badly aimed hammer....=(

Rebuild specs b4 u ask are

compressor- T04B V trim

top 52mm

major 72mm

VG30 .7 A/R exhaust housing and turbine

      Boost cut after swap(RB25DET NEO) R34

      By GTSBoy · Posted

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Boost cut after swap(RB25DET NEO) R34

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that

      S1 rb25/s14 starting problem

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      By Duncan · Posted

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi
