know whats weird... last time i was up in the 5k+ range with my 22re, it seemed to have all the power in the world.. was doing 85 going uphill and still accelerating! step on the gas at those rpms and it just shoots forward with no hesitation. after i did that run, it ran GREAT! guess i had to blow the gunk out of the motor. ...though the idle adjustment screw on the throttle body flew out and i drove around for a week with a bolt jammed in there LOL. so i dont reccomend doin what i did. i think on my 22re ive hit maybe 6600rpm? i know it was something crazy like that, the RPM needle almost hit the the bottom of the cluster, but when i get it back im not gonna try it again just to see what it was.

I used to click my ECT "power" button and run it up to 5k or so, that was pre head gasket failure, now that I had my head gaskets replaced I keep it under 4k!! I think if you have headers revving higher would be safer because you don't have the ridiculous cross over exhaust manifold blowing all of the gasses from 3 cyls up into the other side then out the back... I cant wait to get my Thorleys installed, they are still in the " ceramic coating stage " according to the MFG.. Its been over a month!! Running at those kind of RPMS Id be afraid of blowing something... again

Ever heard of floating a valve?? Revving an engine with no load on it is very bad for the engine. They aren't made to be revved that high with no load.

"A high-rpm engine condition in which the valve lifters lose contact with the cam lobes because the valve springs are not strong enough to overcome the momentum of the various valve train components. The onset of valve float prevents higher-rpm operation. Extended periods of valve float will damage the valve train."

Got any documentation, or other type of proof, to back that up?
I can hold my 88 3VZ-E at 6500 rpm steady(without hitting the rev limiter). So I know for certain it's higher than that on mine.
Maybe we're all just trippin'...
Though I HIGHLY doubt we are.

Granted that I'll accept that as proof, it still doesn't prove the entirety of your previous statement. It would only prove that your 93 3VZ-E reaches what might appear to be the rev limiter @ ~6250 rpm. It would also prove your extreme naivety about the 2 Toyota engines of which you spoke. Since what you obviously don't know is...
1. A 22R-E is not a 3VZ-E. What applies to one, MOST CERTAINLY DOES NOT APPLY TO THE OTHER.
2. 92-95 3VZ-E ≠ 89-91 3VZ-E ≠ 88 3VZ-E.
3. Namely, the ECUs are not the same for 92-95 and 89-91 and 88. All 3 versions have different ECUs than the other versions.
4. The very likely difference in rev limiters between the 3 versions becomes very apparent when you read this entire thread from beginning to end. Given that the statements made resemble the truth. They would suggest that the 88 might have the highest rev limiter. The 89-91 might have the next highest. And the 92-95 might have the lowest.
5. You'd better know your Toyota trucks pretty damn good and thorough before you try to argue with me about them.
6. From the sounds of it, you shouldn't be so sure of yourself.

Wish I could bypass my limiter. I keep bumping it lately at 6200 ish for a 95 auto... any ideas besides after market ecu?
You could try draining the oil and running it. Oh I assume you want to ruin it right?

No valve float and still useable power. If the rod says hi then so be it. Oh by the way my aluminum gaurd is still doing great.
