What would be a safe max rpm for a 22re, and is there a rev limiter on these motors?

blue_CA_yota

I take mine to trips around 5000 rpm all the time.. Passing on country roads, merging on the highway.. The motor makes peak horsepower at 4800rpm..

As for rev limiter, I believe its set at 5500 rpm, but I've never hit it.. Motor doesn't want to rev that high, so I don't force her to..

I tend to shift normaly at 3k, but on the highway, IF i can pass, i'll run it up to 4k, never really been over 4k

iamsuperbleeder

rev limiter is 5750 IIRC

"safe" limit though? I'd try not to keep a stock motor above 4500 for any extended amount of time

but if you had a built bottom end with ARP main bolts and rod studs, and some top-quality main and rod bearings, as well has some I-beam rods and forged pistons, then wind that SOB out

I rarely go past 4k. With 361k Kms (225k miles). When i do it doesnt sound healthy.

Alright thanks guys.

i run mine at 4500 rpm on hills for 10 minutes at time sometimes, these motors are dogs below 3000 rpm, when i'm going on the freeway or just really need to get going sometimes I go to 5000. But your motor doesn't live until it makes it past 4000 lol.

I'll take mine past 5k, of course, I love to hear myself talk...I MEAN hear the tone of teh exhaust...

I guess Im to used to riding bikes, mine is always high in the revs except for highway or constant speed driving.

I shift when the truck goes it goes "VVVRRRRRRRRRRRR" instead of "woooom"
but inbetween "WHHHAAAAAMMM" and "WHARRRRR" is the sweet spot for torque/HP.
(i dont have a tach)

I hate people who get made at the 22re for being "slow" so they just shift at 5k each time.... Its a freaking 4cyl truck... "Toyota Recommends To shift between 2-4k."

When the power band doesn't start until 4K?

I do a bit of semi driving every now and then and you really need to stay in the powerband especially on gradients. I guess the driving style has just imprinted on me....When I press the pedal I want to move, not wait for the revs to creep up to the power band and then start moving. I have actually only owned one car, been riding bikes before this. I don't think I ever let them drop below 10K haha.

2 speeds...stopped or flat out

Hahaha! Awesome. That sig status material.

I try to shift before 4 or 5k but when im offroading i tended to have a led foot and would have it at the rev limiter all day. I have roughly 279,### miles on the original motor and tranny... but thats before i had it taken from me

but you can get around town without ever breaking 3k...

So I guess I'm really asking for trouble ! lol

I have always heard these are truck motors - built for trq down low more than high rpm hp. Yet Toyota engines over all are considered quite bullet proof and able to withstand abuse. Their DOHC motors sure take some RPM's without grenading. The bore and stroke are very similar to the 4.6 DOHC Ford I own and it is considered a rev happy engine.
The 22RE has a forged crank - forged rods - over head cam (generally better for high revs) and the rod/stroke ratio isn't bad for rpm's either - so do they actually break at high RPM's or are they just not tuned for that ?

My stock 22RE has no MAF and a turbo now - and I have the rev limiter set at 5800 RPM because I've heard these engines don't rev - but man is it still pulling hard at the limit - I'd love to move it up to 7000 and see what happens but don't want to destroy the engine just yet

thoughts ?

ive never hit the redline, the highest i ever got it was probably around 4k but i dont have a tach so im just guessing. the p/o would take this thing to redline everychance he could get...and hed keep it there for a long time....

I shift between 3 and 4K every day. Sometimes on a trail I'll hit 5K doing a stupid slick climb before I grab second gear (in 4 low). It's a truck engine....

I always shift at 3K or lower.

This... Like "I know! Lets change the laws of physics and make something into something it's not even supposed to be!"


Max safe RPM? The same as any other 3.5" of stroke motor with only 3.62" of bore...


And put yer calculators away, that's only 2.4 liters...

Wiki:
"However, its weakness is high-end power. The 22R has a large displacement and a strong block, but its comparatively long stroke limits its use in high revving applications. Thus, the Toyota 18R-G, 2T-G, 4A-GE and 3S-GE 4-cylinder engines are better suited for performance applications."


You know what REALLY ticks me off about 22R's? Going 300k miles and getting around 20MPG doing it... DARN YOU TOYOTA! How DARE you!
