Under full load one of the lights on my dash is flashing.

But not all the time just sometimes.

It flashes orange and it's got what looks like 3 or 4 of these shapes ~ except verticle sitting above a rectangle type shape.

Looks like an overheating symbol i think but not sure.

Anyone know why it's doing this?

Also what it means and what it's telling me is gonna happen if i don't back off????

Anyone???

more than likely its the check engine light...

it means your car is detonating (knocking) when you're giving it some stick

The light flashes when the knock hits 60 or higher...so I suggest you stop loading it up because you will blow your engine :D

It's not the actual engine light. It's on the right hand side on the right of the oil light.

And with the cat i know that my cat temp wiring has been damaged and is probably not working when the cat was upgraded.

lol lots of different answers in this thread.

are you running the standard computer? If so its the cat temp sensor which is meant to warn you when the cat is blocked. pull the cat out of the exhaust and see if it is ok.

is it a powerfc? If so its knocking and you need to a/ drive carefully in the meantime b/ check the car out on a dyno and retune if everything is OK

Doesnt the PFC pulse the "check engine" light for knock and the "cat over temp" light for ... cat over temp :D

I don't know! I hope it's the cat and not my engine knocking.

It'd make sense wouldn't it?

Whack.

Anyone?!?!?!

R32 PowerFC and other older legacy PFC"s -> exhaust temp light flashes

R33 onwards PowerFC and other newer style -> engine check light flashes

given that you have an R33 then it will be the RED cat temp light

the powerfc does not use the RED cat temp light so you will have the stock ecu

in this case the CAT is overheating or the cat temp sensor is tripping out

It might be my cat sensor cause i know mine is damaged.

      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
