hey all

iv got a mate whos not a member... i dont know why hes not, WHAT AN IDIOT!!! lol

anyways his problem is

hes got an r34 gtt 2door

while hes driving anywhere... usually above 60km/h, all the electrics shut off and the engine dies,

till he comes to a stop...wait a few minutes and then starts up again perfectly fine....wierd

hes taken the car to a local mechanic and aparently it requires a "hot/ cold sensor".....worth $900 from Japan

now...... iv never heard of this. im a 3rd year app mechanic n iv asked many friends at work... no idea

any help? is my mate getting stooged?

cheers

my mate had a similar issue with his ceffy after he put in his rb25 and didn't have the dash connected up. there must be a resistor in the dash (or somewhere between the ecu and the speedo sender) that reduces the voltage as my mates ecu was hitting the speed limiter. but i don't think it was actually shutting down.

maybe there is an issue with the AFM that is putting it into limp more. i would suggest getting a consult cable for about $60 and check the ecu for fault codes. the electrics shouldn't shut off if it is simply a leaking bov, etc.

actually i hust had a really funny thought. if it is happening at a regular interval, it could be his turbo timer if he has one. there could either be a fault in the ignition wiring that is making it think the ignition has been turned off, the turbo timer may be faulty, or the turbo timer may be wired up incorrectly.

i just remembered that a mates 33 i put a emanage ultimate into had a dodgy harness and when bumped it would just die completely and nothing would work. it was like it had a flat battery. just had to push the harness into the ecu's nice and firmly and it was fine.

hot/cold sensor is very non-specific.

are there any errors showing on the ECU? try plugging in a PFC and going to sensor check. Since its a 34 I'm going to guess it will be showing THRO error which is for the little map sensor at the rear of the plenum. The sensor itself is pretty reliable but the loom it it often fails - therefore $900 from jp would not help.....

    • Hi all. Been a while but things are moving along. I just have something that I am wondering about. Since I will use OEM turbo oil pumbing, I got myself a new bolt, the one that goes into the engine block oil feed. As I recall (and see visually) this bolt comes restricted with I think a 1.7mm hole? Not quite sure but it was something around that size. The turbos have 1mm restrictor bolts installed, as necessary due to ball bearings and my higher oil pressures. Can I now just use that OEM bolt with the 1.7mm hole in for the engine block or will this actually be too much oil flow restriction and I have to drill it out first? In my head it would make sense for the bolt to be at least 2mm wide as both turbos take "1mm of oil flow". Do let me know if my logic is flawed here, I just want to make sure I don't kill my turbo bearings with too little oil. Don't know if I can trust the saying I read somewhere that ball bearing turbos essentially only need an oil mist
    • There are several aftermarket options available, from not-too-painful moneyhttps://justjap.com/collections/driveshafts-bearings/products/d-max-reinforced-replacement-rear-driveshaft-set-fits-nissan-s13-s14-s15-r32-r33-r34-c35 and  https://justjap.com/products/crank-motorsport-billet-rear-axles-fits-nissan-skyline-r33-gts-t-r34-gt-t?srsltid=AfmBOorQk4xkGUa98kO7v2ePLUiNt-HRrM2AwWNw9mbSIVE1ujBVwY__, all the way up to The Driveshaft Shop https://driveshaftshop.com/skyline-cv-axles/
    • Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.
    • Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.
    • Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers
