maintaining high RPMs with 22R-E

cosmo · 08-12-2008, 07:13 PM

Is there anything wrong with maintaining over 5000 RPM for extended periods?

During a recent trip from Allenspark to Glenwood Springs, I maintained about 5000-5500 in 3rd around the Avon/Vail area on I-70 for about 20 mins.

Got it up to 106 in 5th

just wondering if I should have concerns about revving this high for so long. valves seem to get floaty above 5300.

I normally shift around 2400-3000.

When pulling grades, I maintain 3000-4500 in 3rd, such as when driving up Highway 7 to get to Bunce.

I wouldn't recommend it. The valve train is weak in these motors. I know first hand with my 2wd pre-runner. I used beat the living piss out of it. I have personally took it to 7500 many times. Why? Because I did not care and I was bored. Well the head gasket went and I pulled the head and sent it out to the machine shop. The valve seats were hammered so they had to install new valve seat and redo the valves.

? what motor were you reving that high?

any stock Toyota truck motor that has factory Efi will never see above 6,250 RPM. they have rev-limiter that wont allow it.

as for the op, as long as its not a high mileage motor you will be fine.

thanks for the replies...

I don't know what you would consider high mileage, but I have a little over 210k miles on mine...

cosmo · 08-12-2008, 09:24 PM

and yes, how did you manage to rev to 7500? The stock Toyota TCCS ECU won't allow anything over 6250.

What engine did you have? a carbed 22R perhaps?

thats gettin there lol. i would keep it below 5000rpm if its gonna be at that rpm for 20 mins..

My understanding is that a 22RE will take that all day, but a Jeep 4 cyl would self-destruct in short order. 22REs are tough, so you'll be fine I think. Just make sure you have good oil in there. Toyotas seem picky about clean oil.

yeah i once towed a trailer with 3 motorcycles and my canopy on full of tons of campnig geer, maintaining 75-80 in 4th gear at around 5000 RPM's in my 22re pickup and had no problem towing for a 3 hour period.
