i was actualy looking at goin 600cc nismo injectors.. wolf3d (**** that afm off) and yer mods to go along with it

You need a job first warick, removing the AFM isn't always the case!

P.S who's tuning it up here!

Had a wolf before I got the power fc, wouldn't recommend it, as it was send really high coil charge time causing car to misfire constantly at high boost and fry most of the coils that why I got spitfires, also idle and cold start where really bad compared to power fc's but if you have really good tuner might be alright.

I've heard stock injectors are alright under 250 rwkw and 1 bar should be under that without cam and coils. You'd also need a Z32 air flow for more boost anyway, also might be worth looking into 2nd gtr injectors as my 555cc injectors max duty are only about 70%.

Sweet cheers. I have to buy a new turbo anyway, but can't afford to do the clutch, AFM, PFC, injectors and pump, FMIC and GT-RS all in one shot.

Does it sound silly if I get what I can afford (basically everything but the AFM, injectors and pump) and use an R33 actuator on the GT-RS to keep boost right down just to get the car on the road, even though it won't be all that special until I can afford the fuel etc upgrades? As it is at the moment I don't have a running car (other one was written off) so the fact it won't be running anywhere near potential won't bother me.

Reedy - thats because of the actuator that HKS supply with it. As I said before, I I'd like to run an R33 one on it - which is sprung to around 7psi. That way, in theory - the minimum I'd be able to run would now be 7-8psi :P

my understanding of the stock r33 turbo system is the spring is 5psi and the dual stage boost solenoid it uses opens the boost level to 7psi after 4500rpm. is this not the case? my r33 came like this and many others have too and theres an easy way to bypass that as well. with my hks evc turned off im stuck at the spring level which is 5psi

correct me if im wrong i just thought that was how it worked

The least I ever managed to get mine to was 7psi (the R33 electronic boost solenoid raised it to just under 9psi at 4500rpm). Not 100% relevant anyway, I want to know if it'd be safe like this :P

      High temp brake fluid?

      By Komdotkom · Posted

      Reasonably hard, although I haven't run it with the new Endless setup yet. The old brakes were F50's on 335mm rotors and the car did a 1:40.6 at Phillip Island which is a reasonable time, I'm seeing high 600s on the temperature paint. A guy I know ran the Endless fluid at WTAC without issues and he was doing 1:33's I think (Evo) with a 355/332 setup. I don't get out to the track as much as I'd like but we put the car on the hoist and spanner check every bolt and re-paint mark everything, bleed the brakes, change the fuel, check the coolant system and re-bleed blah blah blah before every event. Motorsport is expensive, RB's are expensive so a couple of hours before an event is time well spent. It's also a net time saving because if you can keep your RB from self destructing it saves you time in the long term!

      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.
