The 22R is a very reliable engine, so is the 3.4 I own both, I like my 22R alot, but my 3.4 has balls, big balls, big hairy man balls. 3.4 FTW!

Friend has a 2.7 Tacoma 5sp that I've driven many times. Definately a very capable truck. Has done very well with everything we've thrown at it. The only downfalls are passing on the freeway (going uphill) and hauling/towing. For those reasons, I am very glad that I have my 3.4. Even with the auto transmission, it feels so much better and hauls with ease. It's well worth the 2-3mpg handicap.

Even if I were to do it over again, I would go with the 3.4. Auto or 5 sp, you can't go wrong.

I've driven all types. And I have to admit I like the 2.7 with a 5spd. I would take a 2.7 over an older 3.0 any day. Just no comparison there. That being said, I own a 3.4 5spd. Not a big fan of any of the automatics and I would rather have a 5spd behind either engine. A 2.7 5spd truck would be a great daily driver. I'm in need of a new pickup. The 4runner is great but sometimes you need a truck. I'm considering getting a 2.7 5spd for that purpose.

I've had my 2.7 for 3 1/2 years, and contrary to what everyone is saying, (sorry to be that guy) I wish I'd waited around for a 3.4. I get decent gas mileage, yes, but, I can't stand the fact that I can't maintain 65mph uphill without double downshifting to third. I'd trade the 3mpg difference for the horsepower difference in a second. I'd go 3.4.

Hey that's why I started this thread I wanna know, learn from others. I've been looking at trucks and most are 3.4L I've found only one 2.7L. A guy I used to work with has a '03 2.7L never drove it wish I had.

look at his sig. He's running 305's with a 2.7 so take his experience with a grain. What gears does he have. Should be 529's

I second that.


the 2.7 w/ 5speed in my tacoma had enough power with stock tires... with oversize tires it was drastically underpowered

the 3.4 w/ auto in my 4runner I like much better. I would like a manual but the auto is not bad. the ECT button helps control shift timing if i want some more oommf. Fuel mileage.... depends how you drive. "normal" driving, without much hard acceleration I get about 16-20mpg with the 3.4. Upwards of 20mpg on the highway. the 2.7 wasn't much better, as quoted.

I really love my 3.4L. I get a solid 19 even with the life and tires. I did a 1500 mile tow from Cali to Texas a few years ago and she never skipped a beat.

I really hoping to find a 2.7L but in my neck of the woods they are not common. I looked at one but it was extremely dirty and the lot it was on was very "shady".

Food for thought

I have had a 90 4Runner for about 8 years with a 22re and 5 speed tranny. I was bummed about the pick up on steep grades and freeway driving. I threw in a 268 torqr cam from engnbldr, and have had increased pick up. You have to run the valves a little tighter according to his specs, but between 2800-3200 rpm, my engine jumps into a sweet spot--I can cruise uphill in 4th at 65mph.

I am looking at a 99 Taco 2.7L 5-speed today. I thought that I wanted to get a 3.4 for the added ponies, but in the end, I think the reliability and cheaper maintenance of the 2.7 is the way to go.

Unfortunately Engnbldr doesn't make any parts for the 3RZ, but LCE Engineering has a bunch of components to help you get the 2.7 doing more for ya.

the 2.7 is more rare than the 3.4 in the 4x4 trucks, i have a 2.7 in mine totally stock and have had it on the bumpstops hauling stuff and it did fine. and i must mention that it doesnt eat oil like some engines. great engine imho i think toyota really nailed it with this one. and dont let the manifold issue get to you, im almost at 200k and its perfectly intact.


altho sometimes i like to race duramax's and it does lack a little power.
