sorry to hi jack, recently installed a rb20 actuator and now its overboosting to about 16+psi !. I've been reading and believe i hooked up everything correctly. I'm puzzled now :S. Current mods, 3'' bellmouth and zorst, turbotech boost T set to ~12psi and a nistune remap.

Prior to this problem I had another 1, my boost would drop from 12psi to about 10psi only in high revs (5500-redline), the actuator was suspected so i replaced with rb20 1 and now this :)

Any ideas guys?, only thing i changed during isntalltion was extending the vac line from actuator to boost T to cooler pipe to reach. :S

I take it you have ditched the stock solenoid? Tried adjusting the boost T (without regard to any markings on it i.e. adjust the boost downwards)?

I havn't adjusted the boost T yet. I just put the rb25 actuator back on and its back to square 1.

My next question is, does this mean the rb20 actuator is faulty? OR could it mean that i need to re adjust my boost T?

I only didn't want to touch the boost T was cos its tuned for the ecu already and i dint wana change the settings being a manual BC its very annoying to adjust to the boost you want. hmmmm

      R43 GT RB20DE neo 2.0 liter manual swap

      By Duncan · Posted

      Sure, but the result will put so little power to the ground it won't be able to move. Whatever your reason, it will be cheaper and more practical to sell the manual and buy an automatic

      my current daily - BiTurbo Diesel SQ5 8R with a remap and some light cosmetic mods. Which is sitting in front of my old daily that hasn’t been driven in 7 years now, home to numerous redbacks no doubt. MK4 Golf GTI with a boser hood extension, air ride airbag suspension, factory RHD Xenon’s from the Japanese R32 and stubby electric mirrors (also from Japan) sitting on custom made 18x10” Work Meisters for the golf’s bolt pattern and offset. one day I’ll revive it as a project, pull the engine out, put some forged bits in, chuck a big turbo on it and tune it to somewhere around 250kw and call it a barn find to make millions off YouTube views. Till then, it is a good breeding home for redbacks and the boot is good for storing my Christmas tree for 11 months of the year.

      Misfire/stalling issues

      By Chris_Guthrie · Posted

      I got another MAF and installed it. Idle misfire was still present. Finally got the tank low enough to refuel and did so. Did a short drive to warm the car up and no issues, pretty short drive. Going to attempt soon to take a longer drive to see. I don't think the MAF fixed it if anything, definitely thinking it was fuel related. As soon as I put fresh fuel in the car felt so much better. But, still need a longer test drive to verify. I'll report back once done.  I'm definitely going to be getting monitoring and tuning parts soon as my next upgrade (decided on the link after talking with my tuner), just been real tight with just purchasing the car and sudden onset of issues. I've also ordered a new exhaust stud kit and gasket to fix that obvious problem. Once it's back up to par I'll start with the goodies
