well since the S5 NA was limited to 8250rpm, that would probably be a good place for you too.

Shift according to powerband.
Don't set a rev limiter. You'll do more damage hitting the rev limiter under load than you will slightly over revving it.
Your internals and counterweight are good to around 8200, same as the stock iron seals. I'd try to keep it under that.

Rev limiters hurt rotaries.
If your oil pressure is good then you can safely take it to... hmm. My car has stock internals with just a little clearancing and a bump in oil pressure to 85-90psi and I hang it off of 9500, and I've pinned the 10k tach on a mis-shift before. 2mm seal engines are much more rev friendly than the old stuff.
With a turbo I'd REALLY be worried about the effects of a rev limiter on the engine's effective VE. If the rotor face comes around twice before firing, it will have fewer exhaust residuals than if it didn't, so you might detonate. This in addition to the natural bad effects of a rev limiter to begin with.
If it were mine, I'd find where the engine stops making power, then retard timing REALLY far after that point. This actually is my plan after I upgrade my injectors, since right now my "rev limiter" is the fact that the injectors are wide open so the engine runs so lean that it can't make any power.

Thanks for the info. Ill definetly take heed to that. But a couple of things i think you assumed/ im not sure about.
My motor has not been rebuilt. Its a jspec with 70k orginal miles. I dont have any oil mods to increase pressure. Also Im not sure what VE stands for.
How far should I be retarding my timing? And in what incrementation? Would you mind showing me your timing map?

Hi, I have a question, the other day I was in my 88 fc3 turbo2 and I was in 3rd gear at about 6800-7000rpms at 12psi, and somethin happened, I have like no power at all, it barely idles and very hard to crank up, blows smoke out the tailpipe followed by a flame, it ran perfect before this happened, can someone please help me??

if you're running a stock turbo its not going to make power past 5500 anyways
