Hi all, I was a member about 6 years ago and now I got myself a fresh import gtst so I'm back in the game.

Just received my 32 off the boat and was so excited to have another 32 in my life but... my joy was short lived.

After a initial drive, i noticed the car was losing power at random points and when i put the foot down it suddenly goes again and loses power again.

This was the first problem. second is when I had to stop behind another vehicle, at low rpm even with my foot down on the clutch, the car shut down completely so I had to quickly restart it.

I initially drove home and after the first 10 mins of problems, it behaved OK even in the evening when I took it out again and gave it a good run (That's what I thought it needed after being stationary fir a while)

This morning, I gave my new baby a wash and a wax and started the car to warm it up and went inside the house, 5 mins later I went out again because it was too quiet, but to my surprise and horror, the car shut down by itself....

I attempted to start it and it did, for about 5 seconds and RPM dropped and died. this repeated about 3 times before I left it alone for about 10 mins before attempting it again.

10 mins later it started after I put my foot down and it somehow managed to stay alive. I went for a drive and just around the corner when I stopped at an intersection, it died again.

My first skyline had a similar issue, from memory it was the Air Flow Meter.

I was reading the posts and found some similar cases but wanted your inputs in diagnosing what it could be.

The car is a 1993 R32 GTST done 67km Japanese auction grade 4.

its got a ARC super induction box, aftermarket intercooler, and a non vent to air bov.

My first guess is either the AFM or the TPS or coilpack. since it sometimes takes a bit of crank to start her up.

Please let me know what you think.

... started the car to warm it up and went inside the house ...

Please don't do that. It wastes fuel and causes damage to the engine (most engine wear occurs during warm up). Also makes the car vulnerable to theft, as one Porsche owner in Canberra can attest!

Back to your problem - get the injectors cleaned, new spark plugs, change oil / filter.

So could be spark plugs, afm,

What is AAC? Timing= belt?

Fuel pump and pressure seems to be ok, but fuel filter I'm not sure about...

And boost leak? The car was running fine after the initial fit it had so I assumed was all good but I was wrong... Seems to boost well when it's working so maybe no leak,,

And finally.. Never knew warming up the car can do damage..... Is this really the case? I thought it was the opposite

One more question for you then, the car sometimes starts up well, but sometimes needs a good crank + tap on the pedal to start up. Is this just old spark plugs or coilpack or a battery that may need replacing soon?

ok, when i talked to the workshop, the car has a standard ecu and has never been tuned in the past from what they can see.

so that's probably out... but by other things, it means something ignition related no?

like spark plugs or coil pack etc?

    • Biggest thing is you're okay!   It sounds like between the accident, and the drive home, it was a pretty torturous trip again! On the bright side, you took the opportunity to enjoy the event more from the perspective of a spectator, than as an entrant!   Sad to see so much damage to the car. It really has taken a HUGE hit in the front end. If/when you choose to repair, hopefully the rails are straight (At least from shock tower backwards). Hopefully the extra cage coming through there has save most of the chassis rails, and HOPEFULLY saved the motor too. Best of luck when you eventually get motivated to start pulling it down to check it all out
    • Sounds more like what Brad said, that it's mainly transfer. What pad bed in procedure did you use, and did you replace/machine the rotors, or just swap pads?
    • The stutter is almost entirely in the pedal. I don't feel the brakes release and reapply as you would with ABS engaging but the pedal feels that way, without the brakes releasing. It only lasts for less than a second and the pedal is fine again. It's hard to explain, sorry.  I'll get under this weekend and just double check everything is tight. Fluid is at max where I left it.
    • What bedding in procedure did you use?   When you say stutter, what exactly do you mean? Like it feels like someone letting go of the brakes momentarily and regrabbing them again to get you to stop? Re-reading your post, and that is what it kind of makes me think you're explaining, like theres a little bit of a jolt, likely just as you're reaching a stop. I've only had this issue once. And if its caused by what caused mine, you will want to get the car up on stands again and check it over. Mine was a case of a caliper mounting bolt coming out and letting the caliper rotate on the other remaining bolt and gave play in a wheel as it came to a stop. But not every stop either!
    • Yeop... binned it   This will be a summary will not many pics atm and cbf  Fixed the samsonas - it was totally munched Put a new precision 7675 T4 on with proper split pulse mani Got to Sydney to get to car - drove to canberra to get racecar - drive back to sydney that night Next day all day at Plasmaman putting on new clamps cleaning some things up and adding another large engine oil cooler sitting at the rear above diffuser to keep things cooler Next day - Tuesday - on Dyno - killer wikid awesome pumped out really good numbers - more mid range and on lower boost levels Wednesday - first prac - all day again getting the suspension right - had to borrow front suspension again - out do a lap come in - out do a lap - in - what i had just couldnt handle the load at the more consistent higher speeds - got a lap in at the end of the day that was pretty reasonable  Put it this way that lap wouldve had me in 4th in Pro am for the whole event - with only 700 hp and used tyres Thurs first official prac day - lap out warm up - then entered a hotlap with above setting and 80% effort took corners 1,2,3 and into 4 car felt awesome -  rear came around out of nowhere bang into the wall near front on at whatever 140 kmph Done, over, gone Just one of those how did that happen apparently as all indications show nothing out of the ordinary Got to spend the rest of the time at the event like I hadnt done before - was actually Ok mainly as I had my family and my boy is 9 and got treated like a rockstar Long trip home, lost a trailer wheel in nowhere land, X5 airbag suspension gave up half way across nullabour and rode on bumps stops (its now completely fine) had to do a 19 hr drive day on day 3 as accommodation got screwed up so just had to keep driving till found a town with some Now to reassess - hopefully the motor and other things are OK but yet to be seen too. There is no easy fix there is no i'll just order that part and get it sent - we'll have a talk to people see what can happen and what the go is but at minimum its rebuild from scratch struts forward and alot of time effort and $ should and if I return and if but maybe/ when  I have the cage tied into the front strut towers - if I didnt have that things couldnt been worse you can say its just a front end but if you know what goes into these cars... you'll know what that actually means in reality   Car was very fast. Disappointing we just didnt get to show it Effort doesnt win you races though     Apparently this is motorsport !
