So this 32 GTST I bought has a KKR430 on it.

a few months after owning it, it wouldn't boost past 10psi.

Unplugged the actuator today, car boosts just fine, thought I might've had a boost leak etc, but it looks like the actuator is stuffed.

Don't really want to buy another KKR actuator, as Google tells me they're shit at the best of times.

Can I frankenstein a different actuator on to this turbo? maybe buy a standard rb20 one 2nd hand?

Just make a bracket off the turbo so the actuator mounts, match the actuator rod lengths and its all good?

I run an EBC, so don't really care about the base actuator boost level.

Have u tried a different boost controller ie a manual bleed valve to see if its definately the actuator?

my mate just suggested that too.

he reckons to double check the lines from the solenoid, and to try a bleed valve.

will try that first!

It means its a soft 7psi actuator. and if its doing 10psi means its well doing whats its made to do.

I have 20psi actuator that are direct bolton for this turbocharger. PM if interested of killing it faster.

sorry, I dont quite understand. Its run 20psi before, what has caused it to change to not go past 10?

dont really mind if I kill it faster, plan to bin this junk turbo and get a highflow or 2530 once I've fixed a few other things first.

      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.

      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
