hey guys

i just changed the turbo on my r32 gts4, i put in a R33 turbo that was rebuilt and hiflow'd! also using a justjap slipt dump pipe(screamer)

car was running perfectly fine! the turbo lines were just all cut off and a hose fitted and tightend.

coolent is flused and new. car runs fine as it is without steping on it but then when i step on it within like a minute or so the temp gauge starts going up high!

When the car is turned off i can hear the water boiling.

Nothing is leaking!

hope someone can help so i can resolve this problem!

thanks

hmm strange...

the turbo lines were just all cut off and a hose fitted and tightend.

explain this?

you mean to say your running a water cooled turbo, without the water lines attached?

you have not bleed the cooling system correctly. you should fix this ASAP before you damage your engine.

If you are unsure how to do this, take your car to a mechanic who knows how to bleed skylines and get it done properly.

You might have an air lock in your cooling system for when you flushed it. If so, try starting your car with the rad cap open. keep it open even afther the thermostat opens. this way the bubbles will eventually go away. Hope it help!

Take it all the way out. It pays to turn heater on to get the air out of the heater system aswell. Water will trickle out when the air is out. It does take a little while for the water to come out okies.

take it somewhere to bleed it if you arent sure, you could easily have your temps over 100 degrees without even knowing it.

if you INSIST to do it yourself the steps are:

- start the car with the radiator cap off, keep topping it up till its filled.

- turn on the heater to the HOTTEST setting and run it at its maximum speed.

- loosen the bleeder till its around 1 thread till its off and keep it there till its completely bled.

- keep going till no bubbles come out of the bleeder.

you can use some kind of funnel type thing (see below) to help it along.

i dont have a bleeder on mine, i do the old 'put on a sealed bottle to raise the highest point of the cooling system' trick. works well, car bleeds pretty quick. you have to block off the overflow hose for it to work properly though.

I changed the coolant not long ago in mine... I did all the things security has mentioned.... thought all the bubbles were out, took it for a drive and on the pfc it was telling me straight away that the temps were going up... went straight back home (only got down the street) i let it bleed for 15 mins which i thought was enough.... ended up taking like 30 mins with the heater going full.... so how long did u bleed urs for?

you replied 30mins after i posted - i highly doubt you did it right mate.

i wait there, squeeze both of the radiator hoses continuously as im topping up my funnel thing - it just helps get ALL of the air bubbles out. i suggest taking it to someone who knows what theyre doing.

Mate dont risk f**king your engine up, dont touch it unless you know exactly what ya doing, take it, wait, and pay a proffessional mechanic to do it the right way, then you can get that piece of mind and sleep like a baby.

dont mean to sound like a dickhead, but i dont want your car to blow up :)

      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)
