Z32 afm not larger in diameter than the R33T stock unit.

I was under the impression that the afm itself was bigger in overall diameter.At least the stock holes still line up leaving me able to use the current filter.

The only difference asthetically being the solenoid,the post that holds it and the plug.

Maybe i confused it with an rb20 item?Hmmm.At least this afm gives a more accurate readout.

Is it ok if i remove the mesh at the rear of the afm?

People fit Z32 AFM's to gain a larger tuning resolution from them - NOT because they are physically larger. If you do not have aftermarket engine management, get some or you've wasted your money.

Yes it is okay to remove the mesh from the back of the AFM if you feel the urge. Make sure you get it all out though.

Just a pet peeve, the Z32 has a larger RANGE the resolution is actually worse!!!!

Curse you HPI and your misuse of terms!!!!

I don't quite understand what you have written there.

Range and resolution are two completely different things.

According to Sydneykid's magic table the RB25 is good for about 226rwkW whereas the Z32 can do about 255rwkW (has a 13% larger range).

I suspect that simply putting the Z32 AFM would give false lower load readings which would make the car run lean, I would get your car on a dyno and check it out.

if you dont have an aftermarket ECU...

as 2rismo said - you've wasted your money as it wont work without one.

if you do indeed actually have an aftermarket ECU, you also need the Connector Plug for the Z32 AFM also, not just the AFM itself.

do a search in the Forced Induction secion. This has been covered 100's of times in detail

Yes that's what I meant. At least I think so.

The reasoning is sound if the logic is not.

      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.
