How careful driving a RB26

Recommended Posts

Hi guys,

This questions might be stupid but when driving with a rb26 (r33 gtr), how much do I need to care about revs, fast throttle let off and stuff like this. 

My car has around 380 crank hp and 310 whp. (Bigger injectors, twin plate clutch, stock boost)

Of course regular maintenance is done :)

BR

As long as it is warm but not overheating, oil pressure is right and the tune is good, you should do everything to it, all the time, except hit the rev limiter more than briefly.

If you are doing track work on good tyres, oil surge causing loss of oil pressure can be an issue.

If your tune is not right for your fuel octane, or you have a fuel system problem (failing pump, pump wiring, clogged injectors, failing regulator) it could ping and melt a piston (keep an ear out for that, it is a distinctive "rock in a tin can noise")

If your timing belt, and the idler and tensioner bearings have not been replaced every 100,000, do so ASAP.

If it is misfiring, stop pushing it and sort out the problem (many causes)

If it uses oil between changes (I'd suggest every 5-10,000klm depending on what you use and how you treat it), start saving for a rebuild (head and/or bottom end)

If you are America (or wear a Gucci man purse in Australia) and like to sit in car parks in neutral banging the limiter for flames...they don’t like that

Don't bounce off the rev limiter, do a gentle warm-up of the engine, wait ~5-10 seconds for idle to stabilize after cold start and don't exceed ~50% throttle or 3000 RPM until coolant is over 70C.

You might be able to go a little higher like 3500 rpm, just stay out of boost. 8000 RPM is OEM redline so I would really hope it is built to take it.

26 can easily rev to 8500. Stock limit is a sensible choice, though, as they're not making wads of power above that anyway.
