I'm still trying to get to know the mr2 but is it my car only or is it normal for mr2 to run so high on rpms. I'm doing 70 mph and is going 4.5 rpms is that normal?

Is yours turbo or NA? My turbo runs about 3500rpms at 75 mph.

That seems normal to me too. So i'd say its normal haha because thats how mines is. And i own a 91 n/a.

If it's a MKI, that's probably about right. If it's a MKII, it should be around 3500rpm at 70mph for the N/A.

At 80 I am just a little hair under 4k rpms so that sounds a little high.

Which year? 3 spd auto, 4 spd auto , 5spd manual?

It sounds like with OD off in my Celica.

in 5th gear, 3000 RPM should be 60mph, 3500 should be70mph,4000 RPM should be 80 MPH. or at least very very close. if not, speedometer cable(if it has one) could be on it's way out or clutch maybe be slipping a little

How high can the 3sgte mr2 safely rev without the rev limiter on the stock internals?
Or how about with aftermarket pistons, rods, camshafts, etc?

anything beyond redline is pushing it. valve float and detonation are probably the 2 major concerns. there are other concerns too. some of the of other guys on this forum would probably know more about it in detail. i rarely rev my '91 T beyond redline.
