I’ve been collecting parts for about 12 years to build a Toyota. I started with a 1995 pickup but have moved to a 1990 4Runner with a 22RE to better accommodate my family. The plan includes a solid axle swap, a beefed up rear axle, and dual transfer cases. At least that was the whole plan until I saw your articles on the Cummins R2.8. What do you guys think now that you’ve had it for a while? Also, I was wondering if you knew what size tires were on the little red Toyota from the article “Steering You Straight” (Apr. 2017)? I like the tall and skinny look.
We are huge fans of the 22RE, but a powerhouse it is not. While they will run forever, they are anemic in a pickup and downright lethargic in a fully loaded 4Runner. The Cummins R2.8 (cumminsengines.com) is a great option for your 4Runner. Getting it under the hood of a Toyota might be a bit of a challenge due to the engine’s height, but overall fitment shouldn’t be too challenging. The biggest issue at the moment is that no adapter is currently available to mate the engine to your Toyota’s transmission. You didn’t mention if it was a manual or an automatic, but we assume you were planning on keeping the tranny. At present time that’s not possible, as currently there are only adapters for transmissions used behind Jeep six-cylinder engines, Dodge Hemi engines, and GM LS engines. We expect those offerings to expand as the R2.8 continues to gain popularity, so it should just be a matter of time before there are adapters available for Toyota transmissions.
As for the red Toyota, freelance writer extraordinaire Harry Wagner reports that it is shod with 34x9.50-R15 Super Swamper LTBs on the factory wheels. We agree that the tires are just about perfect for the truck.
