89 integra, engine's bottom end.

Hey what are the bottom ends on the (stock) 89 integra LS good for? How many RPM can they handle (as stock)?

Thanks

sorry, I should specify...
It's an 1989 Acura integra LS...

Wherever the red starts on the Tachometer.

Huh? Doesn't the red start at like 6K RPM on your teg? You can take it to 7K RPM?

Anyway, the redline on a D16A1 is 7K RPM, fuel cutoff is 7500. Depending on how many miles are on it I woudn't take it that high. Keep it below 7K.

yeah redline stars at 7k, and no I don't ever take it past that (car has 160k miles on it). I'm really only wondering if (and only if) I changed some stuff out on that engine - valve springs, valves, forged pistons.... - if the bottom end could take 8k - 8.5k rpm for like a quick second (no way in hell I'd drive it for an extended period of time at even 6.5k).
Anyone very tested it ?

But on the fuel cutoff note, how can you change that?

Port and Polish.
