mine is doing the same thing but i havn't driven it up t0 20psi. it just dont seem right i back off when the boost is around 18 psi, seeing as your motor hasnt blown yet i might flat stick it tongiht see what boost it will run and how it runs.

:lol: Whoever told you that is full of crap. Sorry to say, you have been had, if you are expecting that to happen.

For the amount of boost you use (stress on the engine) and the power/response it makes, the turbo is just not worth it. :thumbsup:

its actually caused by the exhaust housing/wastegate design. if u look at where the wastegate gases come out you'll see it hits a wall and has to turn 90 degrees to join the main flow out the turbine. this causes way too much backpressure so gas would not flow out the wastegate just the turbine. hence the rising boost. seen it happen with many of these cheap integral wastegate turbos.

Hey mate, I just blew up a kkr480! On 20 psi, Now running a 560 and its overboosting also. Its hitting 23-24 pounds which is ridiculous! Not sure what to do either? Needs a re tune, im using a blitz electronic boost controller and when i turn it down it still goes way past the set 20 psi... It sucks!

Good luck keep me posted on what you do...very interesting!

Thanks Joey

need a external wastegate might help other option bin it the money you have now spent on kkr rubbish you would have had a good turbo

i guess there is only so much power stock turbo will push out, kkr430 or 480 will push more power then a factory turbo anytime or day so i dunno wats the go with the lies? lol

Lies that a car with no respsonse (only mildy more power) will beat a car with not too far off power and a wide powerband

      What accelerator cable can be used with greddy plenum

      By Duncan · Posted

      I was 99% sure the standard one is long enough to get there, you might just have to change the throttle orientation. If not, I remember someone having used an r31 cable instead, but that is probably harder to find than r33 by now...

      HELP   Hey all, Is there an accelerator cable from another Nissan that can be used on the R33 GTST RB25DET with a Greddy forward facing plenum?  Thanks in advance  Rob

      RB26DETT Sketchy boost mod?

      By ARB26 · Posted

      Or do we think it was installed to give 1 bar of boost max, all day, everyday?

      So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit?

      What should I do next to hold the head on

      By Gareth87 · Posted

      Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!
