Hello,

I have a '99 R34 GTT, its stock apart from coilovers and a pod filter at the moment. I had the joy of being able to have the track to myself and some friends the other day. While going around the track i was wondering, How far can i push the car before things will start going wrong?

Like holding it at high revs and sticking in turbo, and such how well do the stock engines hold up?

Cheers, Zac

Fit a decent oil temperature and/or coolant temperature gauge. If the oil heads up to 120°C, it's time to call it off. If the coolant is up over 100°C, also time to call it off.

As long as the thing stays cool and you keep the oil filled up and the fuel tank above half full, you should be able to cane the engine for longer than you can handle before it will die.

Having said that, brakes and tyres usually go off on the track before anything else mechanical will suffer. Street pads don't handle continuous hard use.

That's awesome, everything stayed really cool on the track. Although i wasn't going as hard as i could have been by the sounds of it.

I did notice my brakes weren't the greatest on the track, they're the next thing to replace on my list.

I've always been told about horror stories of pistons going through the block and such, and to be honest it scared the shit out of me. Next time i'll give it a tiny bit more then

If your not limiter bashing there should be next to no chance of engine damage unless like has been said your hitting high oil or coolant temps.

    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
    • street use or race track, what hose size and why? what factors change with the hose size options ?   see most comon is an10. when you see most oem external coolers are closer to an12? does high volume oil pump like nitto need an12 or 10 be just fine
