Gtr, Maxing At Around 5k Rpm

[GTAAAH]

Ok so this gtr that i'll probably be getting (r32 gtr, 93 model) is making noises and dying out above 6k.

It's sort of like a intermittent ticking sound, that sounds like somethings blocked or ecu is cutting fuel a tiny bit or something is hampering the performance, and it's sort of popping a bit.

It only has 91 octane fuel in it at the moment as my dad was being a cheap ass, so i'm hoping it's just this but, i wouldn't think it'd have such an effect.

The dying is not a fuel cut or other cut, it's not that big and it seems sort of like blocked injectors, just above 5500rpm it doesn't seem to increase in speed, just maxes out.

i know the car has had afm troubles in the past and they have been replaced, so maybe something has let go in that area, but i'd expect to notice the trouble lower in the rev range

Any suggestions? I'm having a comp test done today, to check what condition the engine is, was just hoping it couldnt be turbo or anything like that

Also is a bit of a diff whine at low speeds, e.g. creeping in 1st, normal in these?

thanks

EDIT: Just got the compression test results, and it got 185 across the board, so i'm assuming the test was done with the car warm [b/]

hope you are getting for really cheap.. like low teens.

soon enough you'll be spending another something-teen 'K' to bring it up to scratch.

Oh, so you reckon the problem is something serious, and not just fuel or timing related?
