When i ran my R33 gtr engine without oil (an oil line blew off), the camshafts scored the bearing surfaces in the head. Does anyone know places in the sydney area that can hone these surfaces with the correct equipment (tunnel honer?)

Also, has anyone had any experience with this type of problem? I really dont want to by a new head!

Thanks,

Shaun.

If the score marks are too deep you could be in a world of hurt. They would want to be only very light marks and you wouldn't want to hone them out cause then you will make your bearing clearances even bigger. Your only option is to make a set of cams with bigger bearings which would be very costly.

Its cheaper to buy a new head. :D

I got my head reco done by Hiflow Engineering in Mascot 9319 6022. Talk to Steve.

I'd take it down and get them to check it out, they have done a few RB26 and know what they are doing. I'm sure they can confirm if it can be done or not.

Thanks for the info. I hope i dont have to buy a new head; i just spent $6500 on the bottom end!

I thought it would just be a case of lightly honing out the bearing surfaces, and then taking the same amont off the bearing caps so that the original diameter is maintained.

I had a look at the surfaces and didnt think they were too bad; but im not an expert either.

      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.
