ey all.... ahh just a quick question... i have a r33 .. i need to get it tuned i know!!!.... but for some reason.. it idles fine most of the time...but if i bump up the revs a bit and them take my foot of the accel. so the revs drop... it will hunt... like seriously hunt... sometimes it will just konck out.. other times it will just hunt but about to die... usually if i take for a squirt.. or sometimes when i just have to stop at lights and take my foot of the accel at 2000rpm . . . i dont think its the aac valve or n e thin there . . maybe fuel ??... im running a power fc with t04e high mount and all the rest of it... any ideas n e one??

There is a thread on this, either in the DIY/ tutorial section or the forced induction reference guide. Was having a read just the other day... A lot of people blame atmospherical-venting BOVs & some people seem to have had luck directly earthing the fuel pump to chassis in the boot. Try find it & have a read, may give you some ideas. My RB20 used to do it almost every time I stopped & it drove me nuts!

Clean AFM with CO contact cleaner, but if it drives fun throughout the rev ranges prob isnt this. READ: http://wiki.r31skylineclub.com/index.php?title=AFM

Mine was my TPS, if you disconnect the TPS, does it idle fine?

Does o2 effect idle?

and of course, if it dies when braking at slow speed and turning etc, clean the aac assembly at the back on the plenum.

      Hello! I'm new here, I have an R33 GTST that is currently being finished up! Last year was pretty rough, blew two stock turbos so I decided to build the car. Has been down since November, but I get it back next weekend!

      Hello, I believe my car was imported to America in the 2000s by Kaizo Industries. Would anyone be able to help me find more info on them? I've only found all the basic stuff like that paul walker bnr34, them being shutdown by feds, just stuff like that. Any help would be much appreciated, thanks!

      HKS Vcam Step Pro Issues

      By believer · Posted

      I am using Motec M150.  I am not working on the car myself actually.  My workshop is giving all these info, they are quite reputable in the industry and are very familiar with Motec and RBs and have done a few big setups with VCam and single turbo on RBs.  In fact, they built and tuned my engine from day one.  But they are stumped with my engine at the moment and cannot work out how come the compression is so low with the VCam. They told me that they have now swapped in some Kelford cams (without the VCam) and can achieve around 130psi compression and the low end torque is better, but now the engine is doughy as.  It boosts and peaks at more than 1000rpm slower, with twin HKS GTIII RS, it doesn't get full boost until over 5000rpm. I have always thought the VCam was a bit disappointing at the low rpm. To a point I had to ride the clutch a fair bit to get up a small hill from stand still.  That was when I had a clutch.  Now changing to a 8HP, I don't have that luxury and this problem has become a major issue. I am beginning to think the VCam never work since the day it was installed.  Maybe it was just sitting at the most advanced point, that is why it went good at top end but very ordinary at the bottom.  Therefore, with the help of the Holinger 6 speed and paddle shift, as long as it was moving, it drove pretty good.

      yeah, there's a country that recently started importing Skylines, I blame them.
