Hey folks

I have a question regarding something that's been bugging me for quite some time.

I drive to work very early in the morning (5am) in my R33 GTST, and have noticed that the car takes aaages to warm up properly (by properly, I mean temp gauge past 1/4, oil gauge ~4). And by ages I mean 20 minutes.

During the day, it only takes around 5 minutes of light driving.

When I first turn it on, i let it idle for around 30 seconds before driving.

Mods: Full exhaust, Pod (for now :) ), boost solenoid grounding

I do suggest you let it idle for more than 30 seconds before driving. On a cold morning especially now as its freezing turn your car on and just let it warm up while your getting ready to go to work :) once you get back to your car she is all warm and ready to take you to work :D

Cheers for the replies guys

Maybe your thermostat needs replacing.... it could be stuck open..

I've thought of that, but wouldn't that also mean it would take a long time to Warm up during day hours as well.

It's only like that in early mornings (ambient temp ~10C)

I have a similar issue, and it's obviously not as noticeable on a warmer day as the ambient air is of a higher temp, as such it warms the engine faster. I suspect that the thermo is busted/stuck open and would like to check and replace as necessary, has any seen/done this process? I'm looking for a tutorial. I can drive from my place to work (around 20mins) after letting my car idle for 5mins and the temp guage will only J'just' be scrapping to the 1/4 mark, it usually sits a bit under half when it's nice and warm.

-undo bottom radiator hose off the thermostat housing, you'll only really need to undo the top clamp (thermostat housing is just behind where your water pump is)

-remove the 3 bolts off your thermostat housing

-remove the thermostat (it just pulls out)

-replace thermostat and make sure you get a new gasket for the housing, it costs around $2 for one.

NOTE: if the person who had it before you used gasket maker, make sure you clean it all off before putting the new gasket in. i used the new gasket plus a bit of gasket maker.. i dont see the harm.

-put it all back together in the reverse order... it shouldnt take more than 10 - 15mins, you'll lose a bit of coolant out of the head so have some ready to refill.

-top the water up, start the car, top up some more then bleed your system immediatley... then top up some more if needed.

dont forget to top it up some more.

      I've heard the Tomei USA head gaskets are decent if you want to o-ring the heads but otherwise not recommended.

      What brakes on R34 GTT(Europe)

      By GTSBoy · Posted

      The 296mm rotors are the R33 turbo brakes. The 310mm rotors are the R34 turbo brakes. The calipers are nearly the same, but not. They're the same caliper but the R34 caliper has longer legs so that it sits out far enough to go over the rotor. The pads are the same for both. When you say, "I bough tsome EBC"....did you just mean pads? Or rotors? 310mm rotors fit under 17" wheels. There may be some wheels without enough clearance though. I can't fit my fingers between the barrel of my wheel and the "corners" of my R34 calipers, but there is plenty of room behind the spokes. This is on Enkei RPF1. You can fit 324mm rotors inside a 17" wheel, but I'd be willing to bet that it would be close to impossible with the Nissan/Sumitomo caliper (using an adapter, of course), because the Sumitomo caliper is fatter than the Brembo caliper that is supposed to go on the 324mm rotors.

      Hi. Can someone tell me what brakes(and mainly WHERE) can i buy brakes on R34 GTT? I bought some EBC which SHOULD go on my car(i have GT but it has GTT brakes) but it does not fit, Brakes are "too" small(296mm) Are 310mm be good or? I have 17 inch wheel so no "big boys" but for me driving i just need one that fits and i can get here in EU/Czech.

      Hey. Very valuable information about pitwork, I will pay attention when buying any consumable parts 🙏 As for the carpets - I got a handful of information from nengun, from which it appears that indeed the carpets for the driver's side are OEM. They are not able to show me any pictures due to the long chain of different sales entities but after I place the order, as soon as the goods arrive at the nengun warehouse from which they will send the shipment to me they can send me photos and if my purchase differs from OEM I can immediately return it / cancel the purchase. I think I will give it a try 😉. Of course i'll let you know what's what as soon as i get them P.s. I know the topic is not relevant to the thread, but both nengun and amayama have these SICK 😍 trunk room lamps available. Do you know anyone who ordered them? I need to have one in my car
