^Ahh, I see why you said what you did andrew, but I was actually trying to take the piss that so many young people "read something on the internet it must be true!"

I actually think that tiptronic auto's are the way to go, anice!

stick to what u believe Lee :)

if tiptronic is the way to go..then why are u driving a manual

btw, how do u launch an auto?...do u rev and brake at the same time? then drop the brake? :blink:

yep that is exactly what you do Andy.

With the stock box and stall converter I can stall my car up to around 2,300rpm - which is just on boost and more than enough for a good launch. But when I get my stall converter upgraded, I will be able to stall to around 2,800 - which in my car is making around 10psi boost and around 100rwkw :D

You would be very surprised at how quick my car is off the line. Can't wait until we finally have a drag strip I can get some numbers on.

I think you rev in nuetral then shift it into low drive? thats how i used to make the traction let go in the old CE Lancer with K&N pod and 2 inch zorst.

That is how you blow a trans :blink:

hehe Andrew

im glad u didnt think i was stirring

i had an auto Ford Probe many years ago, V6 but always get out-dragged by my friend's 4 cyl manual :blink:

nah I mate I don't always bite :)

Can't wait until we have a drag strip one day to give you GTR some lessons ROFLMAO :)

I am sure by that time I will own and R34GTR or maybe even an R35GTR :D :thumbsdown:

Another vote for the auto and a shift kit (but I may be a little biased)

For simillar power on a quarter mile it would be a tough call between the GTR and an auto (down to driver skill)

I'd love to have a $ for every GTR i've seen take off at the line and just bog down and do nothing special. When they hook up well they are fantastic, but more often than not I've been disapointed watching the launch.

driver's skill in a straight line? in an automatic? :D

they bog down coz they have a gay-assed clutch that cant handle a 6000-7000 launch

yep I agree with Guy - GTRs are very hard to launch. See how many goes it takes Keir Wilson or John Munro to get their cars down the drag strip. I reckon the good launches would be 1 in 10 - even with their tough clutches/drivelines etc. Of course that is an extreme example, but you get the idea.

Unfortunately Andy, most GTR clutches would fry on the spot with an 8k launch. Few people even try it (I know you are an exception to the rule :D )

Yes I agree with similar power GTR and a well sorted auto would be a tough battle. Remember too that is takes 0.2 seconds to change gears - so having an auto that changes instantly saves you about 0.8 seconds too!

been in some auto turbo cars and some of them go! maybe because of the longer gear ratios, i don't know but i still prefer manual when it comes to twisty turns because the heel toe method feels smoother when downshifting! or maybe i just haven't driven a well sorted auto in the hills

Are they - I didnt know that :):)

u just ruined it...

and launching a gtr at 8k revs doesnt fry ur clutch? unless you have some 500 dollar one than yea mayb but if ur not cheap and get urself a decent clutch u can launch as much as u want it just comes down to how much power ur car is pulling. if ur driving a gtr i wouldnt think you would be getting a cheap clutch anyway lol.. unless ur an idiot lol :P

Autos are very good for launches..

That is how you blow a trans :)

LOL pauly, but not like that :P

    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
    • @PranK can you elaborate further on the Colorlock Dye? The website has a lot of options. I'm sure you've done all the research. I have old genuine leather seats that I have bought various refurbing creams and such, but never a dye. Any info on how long it lasts? Does it wash out? Is it a hassle? What product do I actually need? Am I just buying this kit and following the steps the page advises or something else? https://www.colourlockaustralia.com.au/colourlock-leather-repair-kit-dye.html
    • These going to fit over the big brakes? I'd be reeeeeeeeaaaall hesitant to believe so.
    • The leather work properly stunned me. Again, I am thankful that the leather was in such good condition. I'm not sure what the indent is at the top of the passenger seat. Like somebody was sitting in it with a golf ball between their shoulders. The wheels are more grey than silver now and missing a lot of gloss.  Here's one with nice silver wheels.
    • It's amazing how well the works on the leather seats. Looks mint. Looking forward to see how you go with the wheels. They do suit the car! Gutter rash is easy to fix, but I'm curious about getting the colour done.
