Things you need to consider:

How many ho do you want?

How many hp will the stock internal engine accept before you start having issues with durability?

Re the injectors: Pick some, doesn't matter. I run 700's & it is fine. Sard are good.

Re the fuel pump: Nismo make a good one.

It is worth replacing he AFM's also. Cams gears as well.

There is a thread on Rb26 engines in the forced induction section. Check that & see what others have done & what results they have got.

Depends on what you want to use the car for!!!

If you want to do regular track days i would look at doinfg and external fuel pump set up with swirl pot and the like. If you are just going to use it on the street i would probably look at an Bosch 044 fuel pump.

With regards to injector i would look at the 650's or 700's as they will supply plenty of fuel if you start do do further upgrades to the GTR.

Z32 AFM are definetlety the go as well.

Mine is very similar in specs, am using what I believe to be 550 injectors and HKS cams = 303.5kw at wheels using 18psi not to over-stress the stock internals. Also I am still using standard dump pipes and AFMs!!

really who tuned it..... im gonna run with the 700cc injectors as they are gonna cost me the same amount of cash as the 550cc's...

as for my cars purpose track/street car so a swirl pot and external pump are what im looking at

Hey Mate, Ive got pretty much the same mods as you are looking at. Car is nearly finished being tuned now, I had some Z32 afm's to go on but when car was being tuned I was told the stock ones are good for approx 340rwkw and mine are not maxing out....but if you fell you want them they are for sale. I opted for the 550cc injectors and a sard fuel pressure regulator due to getting them for a good price but I would recommend going 700cc. Also using a bosch 040 pump and aftermarket cam gears. Most of the tuning has been done and the power figure is around 310rwkw but I will post up the exact results hopefully tomorrow.

Tuned at BOOSTWORX-82990621

Was tuned at Southern Hi-Tech Dyno Tune. Could have pushed it further but I decided to keep it sensible and reliable. John keen did the tuning... very good.

If you're after a fuel pump, look here Fuel Pump

you wont find a better pump for twice the price. I'd say you'd want the 044.

This guy will have the pump out to you fast, I only had to wait a day, ie. paid monday night, had it by wednesday lunch time.

      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.
