Big Problems With My R33 Gtst


Recommended Posts

Hi. had some big problems with my gtst r33 s2. Was driving from perth to geraldton and half way there the car suddently died straigt of. no bad sounds or anything just straigt off died. Waited 15 minutes and the car fired up like nothing ever happend. Kept driving for another 30-45 min and then i died of the same way again. only this time it was a pain to get going again. when i tryed to start it, it just fired one crank but that was all. got it running again eventually and kept going for another 10 min until it happend again.

Had the same pain getting it started again but finally made it to a service station. The tank was now half full just about. Filled 24l in it a nd kept driving. Didnt have to many choices far out in nothing. Was driving very carefully (like 80) in 110 sone all the way to grealdton. Not boosting or anything and we made it without any other problems.

The day after (yesterday) we took of from Geraldton to Exmouth. Was pretty worried at this point so stopped at Nissan. They sent me along to another guy who coudnt help me at all. So I decided to push it and took of for EX. Stopped every 100-150km and had a 10 min brake + topping off the fuel. Did the whole trip to EX without missing a single fire.

Still im a bit worried since it can happen again. When i had the problem the first time the tank was 3/4 full. when it started acting up very bad the tank was half full. So the trip from Geraldton to EX. The tank never had a chance to go under 3/4 at all. Thats the only difference i can come off. The car has a Blitz dual boost controller. And allsow the turbo timer seem to be acting up some times with not keeping the car running after i take the key. Guess this can be something to. Bad connnection somewhere.

Just wanted to check if anyone had any idea of what it coud be... Still in EX now (snorkeled with whale sharks today, woohoo :P) so i will be going down to perth again this comming week. Crossing my fingers it wont be a problem.

cheers

I don't really have any suggestions on whats causing it other than maybe a blocked fuel filter, or lots of crap in your tank. But if it dies again near geraldton you'd be better off getting it towed back to perth, none of the shops up there know anything about imports except for one guy but i can't remember where he works.

I had a problem with passengers in the front seat, pressing their feet into the ecu loom, cutting the power supply to it.

Took me a while to work it out, problem only occurred with a passenger.

You may have loose connection.

hey,

Im probably way off, but throwing it out there, my daily an el falcon just died a week back and its apparently a crank sensor, when that happens they become hard to start though, and eventually just die for good,

but then again i dunno if that applies to the skyline, just thought id mention it..

you may have answered your own question - You said the turbo timer may be acting up because it is not working properly? You do realise that it controls the ignition?

Remove it an throw it in the bin anway. If you can't drive relatively steady in the last 30 seconds of your journey, you're a tool.

They just waste fuel and breathable oxygen.

So are you saying 30seconds of driving easy is enough to cool a turbo down before switching it off?? I usually give bout 3 or 4minutes if its been flogged.

yeah 30 seconds is plenty

all the turbo timer does is keep the engine going which keeps the oil and water lines flowing

the oil is to cool the bearings to prevent cooking

its more crucial with non ball bearing units, so the oem unit is fine with instant shutoff

the bearing core wont drop much with 3 minutes of idle

the exhaust housing would still be sub 300/400+ deg anyway

I believe there was some testing done showing after a minute the the turbo core temp rises again or something and can start to cause issues.

Get the turbo time properly disconnected, and remove it.

I agree about removing he timer etc, nothing but a headache.

However if it is not fixed, it very much sounds like a CAS problem. They can play up over time with heat, and by stopping its cooling down and then repeating etc.

Yeah i guess your right, says so on the Garrett website,

All Garrett turbochargers must pass a heat soak test and the introduction of water-cooling has virtually eliminated the need for a cool down procedure. Garrett is one of the few turbocharger manufactures that subjects their turbos to several OE qualification tests. When you buy a Garrett turbo you can be sure it's a reliable one! :yes:

Somthing reassuring about giving it a few minutes though ;)

Ive seen a graph with times it takes the turbo to cool after boosting and for a ball bearing it's not much at all. 10 seconds is more then enough really.

Bush bearing turbos are where you need to give a cool down period.

I have mine set on 20 seconds. But manually shut it off when I turn off the car anyway. Leave it going for a bit longer after a highway drive but that's just for peace of mind that the whole engine has circulated some fluids and everything is normal when shutting down. This probably isn't really necessary but as I said it's just a peace of mind thing

Depending on how your turbo timer is wired in that could be the problem, If your seeing the power to the unit flicker or switch off then back on id check it out

Otherwise as people have said, try and borrow a known working CAS and give that a shot

    • Go to SP mufflers and get the muffler of size you want and make a nice mid muffler. It's about that simple! I have 2x 3.5 Magnaflow straight through Mufflers and while it's pretty loud with the Varex open, it's quiet enough with the Varex closed. You can also buy off the shelf Magnaflow straight through mufflers as well. You also have a turbo to quiet the car down too. Don't overthink it. Buy my extra Magnaflow muffler sitting on a shelf doing nothing (buy it new, ignore this part)
    • Centre-offset muffler under the floor, same as stock. Just....3.5". The change from straight pipe there to centre-offset will mean that you need to remake some of the pipe (add a bend or two).
    • Hey guys. So my R34 GTT has a custom 3.5” exhaust (done by previous owner) with a high flowing cat, and then just a Varex cannon muffler on the back. The car does drone alot and is really loud even on highway driving just cruising, as you can imagine due to the Varex muffler basically being a straight through with the valve open. As much as i love a loud RB, it can be a bit much with no other muffling in line and just driving casually. I wanted to lower the volume output on the exhaust a bit, as well as remove the drone (probably a way to do both at once), and was going to do it all myself as I am a fabricator and have done exhaust work in the past, so the fab work isnt my issue, im just not sure on the right product or type of product to use to get the job done, and i doubt an exhaust shop would be wanting to help me as they wont be making any money from helping me, unless they supplied the product? Anyway any help or guidance in best way to approach this would be awesome   Thanks in advance
    • Meh, whilst the Honda is a "really" good car and has potential if you want to drop coin on, it was uninspiring for me to look at, but, it did serve its purpose and is now in the boys hands, his happy, his girl is happy, as she wasn't to keen on the noisy old Patrol, and most importantly, the Minister for War and Finances is extremely happy that her "little baby boy" (6'2 nugget who is currently training to be a copper, which will make 3 coppers in the immediate "circle of trust") has a well sorted reliable car that doesn't guzzle diesel Me, I'm more than happy with the NC MX5 that I replaced it with, it's a fun little car that I like looking at, like driving, and yes..... I do like the fact that the maintenance and modifications that I have done/will do are plentiful and relatively cheap, well........ while staying naturally aspirated slow that is, and that's all I really need for a fun little daily, I can rev the 5hit out of it rowing through the gears and never really break the speed limit  In saying that wicked word, "modifications", I've already ordered something for some noise and an additional "3 ish" horse powers, or whatever it gives, in the form of a header, and, a new set of "cheapo" BC coilovers that are already sitting in the shed waiting to get put in, I had the same BC's in my old NB and found they were fine for the street, hwy, and the occasional track days I did in it, they have 6kg front and 4kg rear springs which is about 10% stiffer than the stock springs which I found worked well for their price  I've also already been in touch with MX5 Mania in Dural, so once the header is on it will get a ECUTek RaceROM tune there (I cannot rev match for 5hit, and I loved the RaceROM rev match and FFS in my old 86 "RIP") In other, maintenance news, I put some new sparkler plugs in it, and have a new set of DBA Street series pads to put in over the next day or so, I'm running the DBA street series in the SS and Honda and really like them, they work great and are not dusty at all I've also booked in a few days leave over this weekend to give me 4 days weekend do some paint correction and give the leather seats some conditioning and interior some Bissell and steam cleaning OCD lovin', the carpet and interior looks clean, but from my experience with the Bissell IRT carpet, and the steam cleaner IRT trim, looks can be deceiving I've also found that finding a detachable hard top is proving problematic, the main reason why I didn't like the NC initially was the power retractable hard top that I seen them with gave the roof line a weird look, the detachable roof though looks good, and is a same shape as a NA/NB hard top, similar, but unfortunately not the same as it has different fixture point on the front, so fitting a easy to get NA/NB detachable hard top is no bueno New Old cars are fun, cleaning, hunting and playing around brings much joy How are your beasties going? Do you still have the Skyline with the LS???, or Barra??? that you were playing with
