Anybody put a Toyota 2RZ-FE in?

These little suckers seem to have good power and gas mileage. Moreso than our 2.5L's, so I'm wondering if anybody has ever considered putting one of these in?

Just wondering. Drove my buddies Tacoma Xtra cab the other day and that thing was screaming with me feather footing it like I do my Jeep, and according to manufacturer specs, my Jeep is just a couple hundred pounds heavier...

I actually wondered about the late-model (last year) chevy 2.9L 4-banger. Something like 189 HP and 28 MPG at least, lots of them in the late Malibu and HHR's.

I *strongly* prefer to keep my Jeep all Jeep tho. I can live with the low power and I love my 4 angry squirrels. Tho I admit the MPFI is prolly the best overall system on them, lots less hassle. Craiglist out my way, I can pick up a complete 2.5 with MPFI and ECU for $150.

Off topic, I was wondering whatever happened with your gas mileage, were the injectors leaking or anything?

Sounds like a winner!
My trooper with its 4 banger in it had more power than this open top brick I drive now.

Yeah, the gas mileage I've been reading is anywhere from 24 to 30 depending on how hard you run the engine. Even if you could get 22mpg out of it in the Jeep, it'd be worth the swap, as long as you can pick up the engine for cheap (which probably isn't going to be easy).

I'm not entirely sure what it is still. I'm at a stand still with money right now, but a new air filter seemed to help the engines get up and go power, and it seems to do alright on the freeway... Gas mileage went up a bit, but I'm still not at the supposed 17-20mpg I should theoretically be getting with my mens size 4 foot. I'd say I went up from 11 to about 14 with just an air filter.

Yeah I know how money is - I'm unemployed, which is why I did *everything* to get good MPG's. Next on my list woulda been the O2 sensor and FPR.

By the way, did you know that the Chevy HHR has an SS model with a turbo? And a manual shift? I still wonder about swapping one of those from the local junkyards.

Not sure why you would favor the 22RE over the 2RZ-FE... The 22RE is outdated compared to the 2RZ-FE, which has more power/torque and DOHC. So far they seem to be a very reliable engine for only having been around for less than 20 years...

I have thought about it as well, the 2RZ-FE exhust dumps out the same side as the 2.5L, I wonder if the tranny & T-case would work too?

As an aside, the Aisin transmission (AX5 and AX15) is japanese and used in a few toyotas. As I recall the input or output shaft, or maybe both, is different but it's worth doing some research if you're serious.

There's only one swap I woudl consider doing and that's the 4BT. Maybe the izuzu version of the 4BT instead of the cummings version but either one is the only way I would go with a swap, if your going to put in that much time, money, and effort, might as well go all the way for the same price....plus it's a little less of a "gray area" as it's been done and documented before.

just throwing this out there, but i really doubt you would see the exact same mileage in a YJ. first of all the YJ has the aerodynamics of a large brick. so lots of wind resistance the Taco does not have. Also, as you said, the YJ is a bit heavier. Also gear ratios and tire size have a lot to do with it as well. If I'm not mistaken, the Tacos run a pretty deep gear ratio.

And finally, since you live in CA, your gonna have a hell of a time getting the swap approved and smoged. The engine you swap in will have to be the same year or newer than your YJ and ALL smog equipment from the donor engine will have to be re-installed with the new engine. Then you get the joys of dealing with the referee stations and even trying to get in to get it checked over. Unfortunately CA is a real PITA with engine swaps.

Edit: few other potential issues:
Don't think this has been done before as stated above, so you are gonna be on your own as far as motor mounts, trying to find and or make and modify headers to fit, trying to mate up the various systems with the Jeep and gauges and sensors and such.

I've never really paid any attention to the 2RZ-FE. When it comes to Toyota engines I only have knowledge of the 22RE and the 1JZ-GTE and 2JZ-GTE

Now a 2JZ would be a neat swap in a Jeep

When I really think about it, if I was to go thru all that trouble why settle for another 4 banger?

I think a 4.0 makes much more sence
