more boost does not equal more power. it does however mean more heat. so take that into consideration before just "more boost" theory from your mates :). if you can make the engine breath easier then its more efficient and can wind the turbo in quicker (aka reduce lag). a nice 3" split dump pipe and 3" hiflow cat and 3" exhaust will certainly help that. if it breathes more it will flow more and come on earlier.

The basic near std mods that are safe and shouldn't even require it to be thrown on a dyno..

FMIC, Exhaust, new larger fuel pump (bosch or gtr), bleeder, copper spark plugs .8mm gap (NGK BCPR6E).

Dial in 15psi, set ignition timing to 15degree's and it should run fine providing injectors are fine.

15psi is fine on the rb20det.

RB25det I wouldn't go past 12psi.

My RB20DET turbo ran 1bar and towards the end 1.1bar for 100,000km's. (170,000km's total)

I've always believed heat is the killer of the ceramic turbine wheel, not

so much overspeeding as on the rb20det 15psi is not overspeeding.

Dial in 20psi and you may see overspeeding but to be honest, if its not tuned I'd lay bets the heat will get to it first, heat being generated by a lean detonating mixture. :D

Lean mixtures create high egt's, retarded ignition timing creates high egt's.

So.. Run it richer and dial in more ignition timing = cooler egt's. Better for the turbo.

PSI is the boost it runs.

There's no point upping the boost unless you have an exhaust.

Running simply an exhaust with the std. intercooler I wouldn't run more than 12psi.

Replace the stock intercooler with a larger front mount item, you can then run slightly higher boost.

Before you do anything Do a bit of searching via the search button. :)

Learn what everything is and means.

Do a bit of googling also.

I Don't know how much patience cubes has, but seriously man, u jus gotta start reading everything u can to find out about turbos n the rest. FAQ sections are very good. Its helpful to know how the engine works, how the turbo works, and how these components interact as a system.

howstuffworks is an awesome site, any one who doesn't think its worthwhile is ignorant.

I got an r32 gts-t coupe, it boosts 10 pounds (PSI) stock. When people say 0.8 bar or something like that, its a fraction of the 14.7 pounds mentioned before. 10 pounds in BAR would be just under 0.7 BAR (10/14.7)

The whole pound thing is that 1 BAR is what is atmospheric is. It is also what non-turbo cars drive around with. Your average non-turbo car mixes 14.7 parts of air to 1 part of fuel. Turbos force more air into the engine than the normal atmo engine, so if we boost 10PSI more thats around a 75% increase making our little 2lt much more powerful. Keep in mind, that the more boost, the more fuel is compensated by the car. Basically, the more air and fuel you can cram in your engine on 1 stroke, the better. As mentioned before, the cooler it is, the better.

You should find something like that on howstuffworks.com amongst many other useful informations.

Lastly, if you don't already have a turbo timer, get one or take it easy the last few minutes of your journey otherwise you will damage your turbs over time. Keep your car regularly serviced. If you got shit fuel economy (400km to a tank or less) change your oxygen sensor (search for a post on it). Cops love to pull skylines over: if you get pulled over, don't talk too much, and try and see if the cop is dopey with cars so you can trick him out of defecting you which leads me to this - try and keep your as obviously roadworthy as possible.

      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

      After market rear camber arm adjustment

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)
