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.

      I downloaded the apps (for windows) and Consult 1 doesn't have this function on it for the Consult 1 plug which I'm pretty sure all Skylines have. You would think someone would have a workaround after 30 years for all Skylines which have ABS.

      Also, I don't know the actual ABS system on the skylines, but a sneaky thing could be a piece of electronic equipment that makes the ABS think you're moving, and then same piece can send a signal for a locked up tyre... Activate ABS without slamming brakes...

      The team at OBD2 Australia are pretty good, shoot them an email and ask them. I've dealt with them before for work stuff. I'd be shocked if it didn't work, so long as Consult can activate the ABS. But you might need to use KLine for it which would be the stopper, as I don't think that piece does KLine comms.

      Yeah and hence my ghetto way of slamming the brakes, get the ABS to cycle, rebleed seems to be a sensible workaround.

      Hey! Happy to help. Nothing inherently wrong with the adapter, it's more so with Brett Collins himself. He gave me a lot of incorrect information when I was in contact with him and was extremely rude when I challenged him. He stated I could not use any aftermarket twin plate clutches except for his own, not to use the dush shield, bla bla bla and it was all BS.  Collins stated to cut roughly 14mm's off the housing, I took off 15mm to make room for the dust shield. I would confirm with whatever adapter manufacturer you're using.
