even though the Advan GTR started as a GTS4 its had a full transplant of all the GTR gear. Even most of the panels are GTR so its more a GTR than a GTS4. The only GTS4 part I can tell really is the sunroof.... then again I don't know a great deal about it.

The japs seem to like the Profec better but then again the Apexi has the nice rice factor :)

Also if you plan to get a PowerFC the AVC-R is an easy option.

From a practical perspective I have a preference towards the Profec B.

Sure the AVC-R holds the title for the most bells and whistles but in reality, how many people ACTUALLY have time to utilise all its features when driving....I tend to spend more time looking where Im going.

The other concern is that the AVC-R is only a relaible form of controller up to about 1.5bar...beyond that and its accuracy is seriously compromised.

I suspect this is why most of the big name Japanese tuning houses are not using the AVC-R in high output cars.

my advice is get niether i know this will met strong criticism but hear me out:uh-huh: If you have a standard turbo get a dual stage turbo smart if you have a bigg turbo set the boost through the wastegate. Now i just havent said this blindly ive had some experience on both and from talking to an expert in tuning this is my conclusion. you see if you do a dyno run with max boost max everything the computer sets this when you run lower boost it only resets to an extent so i believe your not saving that much extra juice or whatever by running it at a lower boost you better off running your car the way its tuned all the time if this means 15psi then thats it. I have a profec b but im goin to take it off my GTR n put it on the r33 (cause my mum drives it) cause i believe that extra wiring hassle with calibration and weight are not worth the small amount of fuel i would be saving!!:( Just my 2c worth. And i know its mainly the ease of just changing boost that is the luxury just something to think about if your tryin to decide between two part for your car a fmic or a profec b for instance:rolleyes:

bahaha xrsist..

but you aint making any sence...

your telling me to just run what its tuned at (max boost) all the time..

then why the need for a "dual stage" bc??

besides a EBC is much more accurate ...

but the choice between the EBC and a FMI is a good point..

- hahaa.. yea. one of those long days at work does that to you.

Basically what s13drifter is saying is that he would spend his

money on a fmic first before getting a EBC to keep detonation

at a minimal. You do want your engine to last don't you.. or have

you got conrods,cams new head and stuff lined up already????

If you really want to boost it, just buy a stage turbosmart or something for now.. It won't be hard to sell later.

Now back to the topic... If you really want the EBC, then by all

means get ProFec B... :uh-huh:

i agree with xrsist that the profec b is probs better unless you are goin to go to a power fc then the apexi is a better option. The reason that i suggested the daul stage bc is because it is cheap and if you really do need to use 2 different boost settings in your car. I know that they arent as accurate for curving boost spiking but unless you are willing to re callibrate your ebc often they arent as efficient in stopping boost spiking as alot of people think. Im not against them i just thought id mention other options for you Hype, cheers.

The only GTS4 bits left are the shell and chassis....

And I would agree with SadisticRage, the AVC-R isn't good above 1.5bar..... go with the ProfecB

Hype the apexi is better with a power fc cause it can be intergrated into the power fc as they are both Apexi. Im not sure on this but i think the power fc might have a extra pin in for the avc-r and maybe a sub menu through though the computer that recognises that you are using the boost controller. Can any one varify this i could of been told ****:eek:

      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?

      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.

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
