[91 240sx kid]

I have a 94 r33 and once it hits 5000 rpm the motor starts to spit does anybody know what the problem might be? (i dont think its a miss fire)

mabey you should ask the rb section the question, in more detail though!

not just hey guys my car breaks up after 5k, what do you think it is? you check/replace you fuel filter, plugs, fuel pump, maf, tps ect ect ect???????????????????????????????????????????????????????????????????????????????????????????????? \search

What do you mean by "spits"? And why don't you think it is a misfire?

like the motor just starts to break up its almost like a rev limiter which dosnt make any sense and i dont think its a missfire because the car idles fine and runs good until higher rpm

Missfire. Change your plugs, gap them to .8, and if that still doesn't do it, it's the coil packs. Search on skylinesaustralia.com on how to fix those.

what colour's your R33? i just picked up a black one and am just off Craig Henry in Nepean.. haven't seen too many of them in town yet!

misfire.

new plugs, reset your ecu, reset your timing.
