I dreamed that my MR2 had a V8. It was glorious! So I researched what it’d take to make it a reality. Here’s what I’ve got so far...
Most V8s are of the 90 degree variety. Which means they’re too wide to fit in the MR2's transverse engine bay. There is, however, a V8 that isn’t 90 degrees.
That’s right, the Volvo XC90 (and S80) could be had with a 4.4-liter V8. The B8444S is a 60-degree 4.4-liter V8, and is mounted transversely.
Yes, it’s a complicated engine. Balancing a 60-degree V8 is much harder than balancing a 90-degree V8. It’s developed by Yamaha, who also did the 1LR-GUE V10 for the Lexus LFA. Fancy.
However, it’s still a 60-degree V8. This means it could fit in an MR2.
It may be expensive, but it sure wouldn’t be slow. Weighing in at only 418 pounds, this all-aluminum engine weighs about as much as an LS3, (403 lbs) but is more compact in key dimensions, namely width. It’s already built for transverse applications.
Is this a bad idea? Or is it crazy enough to become a good idea?
