The 2GR is such a good engine line. Got a 2008 Sienna and a 2015 Highlander, both came with the 2GR-FE.
If you're feeling adventurous, hit up the MR2 forums (they love this engine), and Marc at Frankenstein Motorworks. Marc has a setup for this engine that'll do 400hp to the wheels, all motor with a stock bottom end.
Agreed, it's really unbelievable. My mom bought an Avalon limited new in 08 and it is now my sister's. >400k miles and nothing but regular maintenance and some rodent repair. They still get >30mpg if they take it easy on the highway too.
The mr2 swaps are where we got this idea, ironically. One of her old roommates is in the middle of putting a 2gr into a 85 mr2.
We can't do a power build though, the poor fragile GM transmission would absolutely grenade itself. And the FWD transmissions are harder to come by these days so we'd rather not damage the low mileage one thats in it.
We just wanted something that got out of its own way and would get decent ish fuel economy. Considering the original 4L v8 made 130 hp on a good day and got 16mpg... A stock 2gr does that plenty.
