What year did Tacoma come out with the 2.7 (4 banger) that I have in my 2001 ? Also what is the difference in horse power between the 22R and the 22RE and the 2.7 ? I'm really happy with the power I get from mine but I guess the 456 factory gearing really helps too. Thanks for any info or openions you may have . Mike

toyota switched from the "pickup" to the "tacoma" in the middle of 1995. i think the engine changed then, too, but i could be wrong...don't think there were any tacomas with the 22RE, but maybe.

other things changed between the "pickup" and "tacoma" also...the tranny, frame, front suspension, etc. etc.

in any case, though...the 2.7 does have significantly more power than the 22RE...don't remember the numbers offhand, but they are out there on the web somewhere.

Thank you for your input. I did a little surfing and found that they came out with the 2.7 150 hp in 2001 for the 4x4 Tacoma with the 16" wheels (31") tires but the 2x2 still had the 2.4 142 hp.
From time to time I see where people compair how many miles they get per tank full of gas and that always seems a little silly to me because the gas tanks also changed in 2001 to 18 gallons compaired to 19.5 in 2000. Plus there is no way of telling one milage from the other unless you filled both of them and ran both side by side on the same course untel they ran out of gas.
Don't know what the specs are on the 2005 Tacoma maybe some of the owners of the new ones will chime in if the engines have changed and gas tank size. Thanks again, Mike

Actually, tank size does not matter when calculating MPG. It only matters in range.

Beartracker

Maybe you misunderstood what I wrote. I agree that tank size does not matter when you are figureing MPG. That wasn't my statement. Some one asked on another thread "how many miles another get's per TANK FULL of gas" and many people were responding to the question . My point was that there is no way you can get an accurate reading because of TANK sizes and conditions of the driving area . The only way to figure gas milage is by figureing actual MPG .
I drove 315 miles after filling my truck and it took 15 gallons to fill it. Filled it again when it was just about to hit the "e" mark and it took 14.758 so I rounded that to 15. 315 devided by 15= 21 mpg.
Some people would figure that I just used close to a tank full and only got 315 mpg but I have an 18 gal. tank so I was far from being empty and could have made another 63 miles for a total of 378 miles for a tank full. Mike

Ummm, ok.

nope ,never and i mean never was ther ea 22re in a tacoma.

LittleRedToyota

i don't think that is accurate...i think there may have been a new version of the 2.7 in 2001 and that could be why there is a difference in the HP, but the 2.4 is the 22RE, and i am almost certain that no tacomas had the 22RE. also, i don't think there was ever a stock 22RE that generated 142hp.

OBDII (on-board diagnostics 2) became mandatory in 1996. the 22RE is a OBDI engine. in fact, i think the OBDII requirement was a big reason why toyota developed the 2.7 (which is OBDII) to replace the 22RE.

there were also a few generations of 22REs...each successive generation had a bit more horsepower. i think what you found is the same thing in the 2.7.

well I have a 1999 tacoma xcab 4x4 w/2.7 in it and I guarantee your reaearch is flawed......2001 was not the first yr for the 2.7.....also the pre-runner is a 2x4 and it had the 2.7 in it also (the pre-runner is the fake 4x4)

[ What year did Tacoma come out with the 2.7 (4 banger) that I have in my 2001 ]

First year for the 2.7 (3RZ-FE) was 1995. Started with 150 hp and grew to 164hp for 2005.

The 22RE started out at 116 hp in 1984 but over the years was improved. Beginning with 1995 it did indeed make 142 hp.

[ nope ,never and i mean never was ther ea 22re in a tacoma. ]

Umm - there were plenty of Tacomas with the 22RE - the last model year was 2004. But they are all 2 wheel drive...

Beartracker

Woh guys! I'm just going by what I read and I don't claim to be an expert when it comes to Tacomas. That's why I asked the question to begin with.
I did a search for 2000 Tacomas and the specs for a 2 wd and the 4 wd. Then I did a search for the 2001 (The year they changed some things and remained the same through 2004) and read the specs and road test results.
I do know that mine is the 2.7 3RZ-FE and I was told that it is 150 hp. I do know that it has 456 gears and 31" tires with 16" wheels.It's also my understanding that you could get the 2.4 in a 2x2 and it is 142 hp.
As far as RE or E or any other letters you want to come up with means very little to me. I like talking HP from one 4 cylinder to another.Makes more sense to me anyway.

Aren't those 2.4 liter engines with 142 hp double overhead cam engines? And also since the Tacoma has the fuel and exhaust on opposite sides of the 22RE trucks, why would they put the 22RE in Tacomas when it wasn't designed for the Tacoma?

I don't know what the 2x4 Tacoma 2.4 liter engine is called, and think it would be something other than 22RE.

2.4L Tacoma Engine (4x2 Models) 2RZ-FE
2.7L Tacoma Engine (4x4 Models) 3RZ-FE

The 2RZ and 3RZ are the same size and look the same. The 3RZ was simply a bored/stroked 2RZ.

this is how I understand it to be.

Thanks for all the info guy's. This site may interest some of you.

Well it took a few posts, but the truth did come out. The Tacoma was released as a 1995.5 model, you can buy a 1995 truck which is not a Tacoma.
The 22re was never available in a Tacoma, as stated the 2wd Tacomas got the 2.4 2rz motor while the 4wd got the 2.7 3rz. Later on they did put the 2.7 in some 2wd models, specifically the pre-runner. Both the 2rz and 3rz are
DOHC multi valve designs, but the 2.7 includes balance shafts which the 2.4 does not have. On the 4 bangers Toyota started the Tacoma line with a distributor, then went to distibutorless but still had 4 wires running to the coil pack, then they switched to direct ignition, or a separate coil for each cylinder. The 3rz power numbers never changed between 1995.5 and 2004 they all made 150 HP w/ 177 torque, the 05 has more power because they gave it VVT.
22re 2.4 SOHC I4 116HP 142 Torque
2rz 2.4 DOHC I4 142HP 160 Torque
3rz 2.7 DOHC I4 150HP 177 Torque
If anyone remembers the first Fontier, Nissan annoyingly claimed that there 2.4 had more power than the Toyota 4 cylinder, but they never mentioned that Toyota offered more Torque in either motor and the 3rz crushed their wimpy Z24, or whatever they call it now. They were simply comparing their 2.4 with 143HP, ooh 1 more that Toyotas 2.4 and 154 Torque, which is actually 6 less than the Toy 2.4, they never even attempted to compare to the 3rz.

thanks for proving me right ,not gloating ,but i was working at toyota when they first came out.

Beartracker

Pat161, Thanks for the info. The only thing I see in your post is that the 2.7 has 177 lbs of torque and what I read on a 2001 4x4 Tacoma test site it said that the 2.7 has 150 hp and 180 lbs of torque.

This site may interest some of you as far as what Toyotas have what engines.

Beartracker, interesting info, I just went onto Edmunds and they list the 2002 2.7 as having 177 torqgue still. If they had 180 for 2001 then that's news to me, I was quite certain they all had the 177 right up until 05.
