Hey guys i got my r33 gts-t today, and it had a hks elec boost controller fitted, the thing is, the guy gave the car to me off tap (unlimited boost) and i ended up hiting 2.0BAR!!! in 2nd gear, fried the tyres something shocking, now its on 1.0bar which is still too high, its on stock boost setting and stuff but i wonder why its still hitting so much boost?

id appreciate it if my question could be answered properly, anyone with a smartass comment, please get out of my thread.

Thanks. phill

if the previous guy has been driving around like that expect some serious failures sooner rather than later.

Maybe try hooking up the standard solenoid agan and see what boost it runs??

sounds like either the boost controller is damanged/faulty/disconnected/failed or the turbocharger boost control system is damanged/faulty/disconnected/failed

check there is a pressure line running to the turbocharger actuator

check the boost controller

try resetting the boost controller

failing all that have a workshop check it out as if you keep driving it you will cause damage if you havent already. your seals are probably shagged or very unhappy now, check the intake pipes for oil

well its running factory boost solenoid now, i know it holds boost because its a t4 actuator on a t28, so its like its been set at 1.0bar? its ment to be hitting 8psi. I cant hear the turbo choking or anything yet. I just dont want to have anything fail on me, as i dont have any money!. Ive checked all lines, all are ok, i wasnt too sure how they sit, but ive put the 2 lines that go into the std controller solenoid in properly, and one goes into the cooler piping? or something like that. Ill take some fotos of how they are now, and you could correct me on what is right/wrong?

Thanks

      Import insurance in 2025

      And that's a massive problem, because deadshits will deadshit and give you false details. At least in these days of mobile cameraphones, it is trivial to take photos of any ID they are carrying at the same time as the 300 photo extensive documentation of the state of the vehicles that I recommend even for minor incidents. And you get photos of the person's face, any visible tatoos, etc etc, while you're at it. Then you try to avoid mentioning that you're fully capable of making explosives of various power levels and will wreck their shit if you are forced to hunt them down.

      No, I don't remember the exact reasoning (was 20 years ago!) but the cops didn't end up supplying it to us either. Actually my mother went through a similar thing recently where she was hit when stationary, flustered and didn't get address (she got plate details, name, phone and insurance company, but not address). Person who hit her blocked her number and their insurance company (naturally) would not provide any details. Her insurance company also required her to pay the at fault premium because she did not have the address, cops did not help as it is a minor civil matter (they said their only course was if the other driver had left the scene of the accident without providing any details). She only ended up getting that refunded because they happened to be insured with Suncorp and she was with APIA so same company owners. For some reason the address is critical in insurance companies recovering money from the at fault party

      If you're driving something like an R32 through to R34, no chance of meeting Euro4. Euro4 came out in 2006, and car manufacturers back then were complaining how hard it would be to meet those regulations. Not a chance a vehicle 10 years earlier is going to be compliant.

      I presume it would take more than just slapping a big modern catalyst on the exhaust? It's interesting though, looking at the old sales brochures and listings it does not mention anything about emissions. No one cared.

      Yeh nice, looks like their part of keep it reet? Will have to swing past. I'd much prefer someone actually look at my car and custom make a part, then get a generic part online and hope it works.
