with the actuator disconnected, the wastegate will never open, which means boost will continue to rise as long as the throttle is open and the engine is ingesting air

this basically means your running unlimited boost - be careful with this - it might go bang.

what spring are u using in the actuator? what boost controller have u got setup?

what exhaust setup do you have? have you checked the actuator / swing valve for play? does the wastegate flap actually open?

im sellin the kkr setup soon and im selling a real good Greaddy td06h-25H polished turbo with top mount mani and gready dump pipe, if u want this will spool fast n pull very hard all the way unlike the kkr that kickes in way too late on such high boost.. let me know if intersted

The spring on the actuator is factory kkr, exhaust 3inch after market turbo back. i have checked the actuator it functions fine, tryed with 2 diffrent boost controllers one electric the other just a cheap t piece style same resault. i have also tryed with no boost controller does anyone no the least boost you can run with this actuator??

so wastegate hole is to small thats my problem?

limiter is set to 7500rpm im pretty sure, but since plenum upgrade and car hasnt been tuned, ive lost alot of down low and turbo comes on really hard bout 5000rpm and then goes straight to limiter...

sounds gay if the boost range is 5000 to 7500rpm is it evan worth it?

    • Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
    • There's not a great deal to report here .... except ...... FOR .... LSD!!!  I bought a Quaife LSD from the UK and shipped it here .... Wish I'd just bought locally cause the shipping and duty was $700! But there were so many diffs used in the E90s I just wanted to be absolutely certain I was getting the right one so I spoke with a supplier in the UK who builds race cars and they have heaps of experience with the E90s.  I pulled the diff out which was seriously awesome - I've never done anything like that before, I must have watched 1000 videos on YT about it as well as consulting the Bentley manual. It was super easy in the end. The diff was delivered to the awesome folks at Hornsby Diffs and will be back in a few weeks. I also replaced the diff bushings with some Nolathane ones.  Really looking forward to getting it back and getting back to the track or even the skidpan.
    • yeah... the 13kg/mm springs weren't always in there, I had 10kg/mm but doing a few SMSP commanded heavier front springs. It's so good now going into T1 and T2, just need more seat time and real tyres.
    • Yes, well. Mine are less than half that. ARBs are not set to "dumb" either.
    • I would hope. But, we all know even the best companies have an issue sporadically.
