Guys,

i'm "tossin:bahaha: " up what mods to do to my car R33 GTR. At the moment it's pretty stock "bar the cat back exhaust, pods & turbosmart bleed thingy valve". I have ordered the Power FC & Hand Controller and about to contemplate the following mods... what do you think, as I've heard various opinions from reputable performance shops.

PS: I'm not after qtr mile times, sprints etc.. just a reliable "every second" daily driver that goes a bit harder & breathes easier than stock.

Mods to go with existing - Pods, Bleed thingy Valve, Cat Back exhaust.

1. Power FC & HC (which tuner - In Vic)

- I know many will say ICE, but I was also told the man to see is Vinnie from Sti Dockland "x owner of BGT - AKA Hyper Tech - AKA Apexi King". Also told without software hand controller only accesses about 30% of the functions.

2. Front Pipe

- I know a good exhaust shop that's done most of my cars. Thinking of getting a custom made rather than Brand Name.

3. Cat

- Told the stock cat is excellent for my basic mods.

4. Heatshield for Pods & CAI

- Goes without saying hmmm.

5. Adjustable Cam Gears

- I'm a little worried here again hearing various opinions from tuners. Most say it's the best choice, ICE have re manufactured GTR Gears for 220 change-over. But I'm worried if there not centred correctly or done properly whether they could damage the motor.

Thanks

Can I please suggest an electronic boost controller? It will help you turbos spool up much faster as it doesn't leak air going to the wastegate actuators before peak boost is reached like bleed valves like to do...

Also a nice set of dump pipes off the turbos are always good too!

Don't do this to me Merli :P My initial order was Power FC, HC & the EBC. Spoke to Nigel from ICE & nearly every one else said the Apexi EBC was shy-zen-howzen because it only had 1 solenoid. They all said the best was the Profec B or something like that. But they could fix the bleed valve to work just fine.

I was told not to worry about these unless I'm looking at hi-flowing or changing the turbos.

Sorry Simon :bahaha:

It's true that dual solenoid EBCs like the GReddy Profec B, Blitz SBC-ID or HKS EVC4 will control boost slightly better than a single solenoid EBC like the APEXi AVC-R or Boost Kit for PowerFC.

Although that may be the case, but if the Apexi EBC is crappy for having only one solenoid, where does that leave the bleed valve? ;)

There is nothing inherently wrong with bleed valves. They'll increase your boost, albeit a little slower than an EBC and spike at little more, but I appreciate that you want the best for your car, and that's why I proposed the EBC :)

Secondly, turbocharged cars rely on the biggest, free flowing exhaust possible to reduce backpressure so the exhaust wheel isn't restricted at all and can spin as fast as possible, creating more boost and increasing efficiency. To this end, it is better to replace your entire exhaust, turbo-back with a larger diameter exhaust, including the cat with a high-flow item. If you see the dump pipes off a GTR, you can immediately see how restrictive they can be compared to, say, HKS dump pipes.

Cheers,

Andrew.

Why bother? The major multinational japanese companies (HKS, etc) have put a hell of a lot more blood, sweat, tears and R&D into their products - as opposed to something knocked up in someones shed (I don't care how good they can weld...)

Nah mate I'm not offended, I was just having a laugh at you sticking the boot in...

My reasoning is often you can get something custom made thats exactly the same as a name brand for 1/3 of the price. Or for say cam gears - why pay $900 for a couple of bits of aliminium when you have some perfectly good ones that can be custom modified for $200.

$900 for cam gears?? That might be aussie shop prices but no one I know of has paid anywhere that much for cam gears.. I got my HKS cam gears for just over $400 delivered to my door.. I personally wouldn't go stock gears that have been modified..

Mesh, really depends on your budget. I run the PFC with boost kit and have had no problems at all, holds 1.2 bar no worries and I can use the H/C as a boost gauge as well...

Mick, just out of curiousity what are your cam gears set at? Adv and Ret???

Cheers

Brett

      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

      By GTSBoy · Posted

      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
