I'm running 272deg 9mm lift camtech cams with a GTX3076r. 300rwkw on 15psi. High quality parts, no complaints here what soever. No VCT here. Can't recall if the 268degs were out with VCT support when I bought mine or not.

bottom to mid is what will be affected by vct. interested to know...

Reflector: post up a dyno graph if you have one

This is without the cams degree'd (currently doing it now - Cars off the road).

Running 14-15psi through an Apexi-AVCR however we're ditching that as the boost controller in the future and using the Link G4 to control the boost. Going to put 18psi through mid range and bleed off to 15psi. Once I get some spare dollars I'll rebuild the bottom end and then the fun begins. In regards to driveability, it's a kitten down low, drives perfectly, put your foot down and it's a lot of fun - need some stickier tyres haha ;). This set up was built with 1/4 mile in mind as well. We had to put limitations (cuts) at redline (7500rpm) as it wanted to keep making power above and beyond but with a stock bottom end, there's not point pushing it.

Thats a nice linear power curve. Looks like mine. We hadto put limitations aswell on my car (7650) for some reason the power doesnt taper off. Never opened up my engine after buying it off a member here so im unsure if the heads had some sexying up or what. I can drive mine all day when cruising but when she's open everybody hears it

Thanks man. I copped a lot of negative responses when stating I wanted to ditch VCT. In all honesty, I'd be interested to see the difference with the same set up with VCT enabled (guess smaller inlet cam with VCT support) but these RB engines really perform beautifully from 3000rpm onwards. It all depends on what your goals are.

Question is, what are you hoping to achieve? More response, more low down torque, more top end power? What other supporting mods do you currently have?

Camtech are a good choice regardless, great customer service and their products are high quality.

Well currently im making 300kw. Tomei fuel pump greddy plenum 3076 .82 with a tial 44mm gate straight through 3 inch exhaust power fc. The usual stuff. Im putting hks 256/264 cams with a hks ex cam gear. Tomei springs. Nismo 740cc injectors. Nismo thermostat. Nismo reg. Iv recently just finished my 044 and surge tank setup. Just spoke to the guy who's tuning it. Im upping the boost to 20 to 22psi. Aiming for 330 plus kw. I use the car for drift and street driving. But I want to break into the 11s and run a 120mph pass. So basically my car will be an all rounder.

      Blue/grey smoke after idle

      By pacman_1219 · Posted

      Even with the piston at TDC there was room for it to drop, but I don't think it can drop fully into the cylinder, the problem you have is that you need something pushing against the valve to hold it up so you have enough room to put the new stem seal on and the spring etc.  I used compressed air only because putting rope in the cylinder seemed a bit risky to me, I know people have done it countless times before like this. Overall it's a pain in the ass job. Honestly you'd probably be better off taking the head off because the risk of dropping something in the engine and the finicky-ness of it all is very stressful. If you are going to attempt it though i 10000% recommend a 36050 valve spring/keeper tool. I had both the traditional lever type and after doing 1 cylinder it was absolute pain to get those valve keepers in place, even with 2 people. That 36050 is amazing, you do have to push hard to get them in place but it works perfectly almost every time. Back to my actual issue I think my engine is just tired and old and the rings have gone bad. The comp numbers (cold, no oil) were: Cyl 1 -129psi Cyl 2 - 133psi Cyl 3 - 138psi Cyl 4 - 137psi Cyl 5 - 157psi Cyl 6 - 142psi   Cylinder 5 and 6 having the most carbon on them.

      R33 Fuel Pump & Brakes after alarm swap

      Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?

      R33 Fuel Pump & Brakes after alarm swap

      Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.

      After market rear camber arm adjustment

      By GTSBoy · Posted

      Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.

      R33 Fuel Pump & Brakes after alarm swap

      By Jarsky · Posted

      Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it.
