You have a point but the
You have a point but the Tacoma needs a steeper and earlier torque curve which is obtained by a stroked engine and not "bored out". More cylinders especially with your recommended forced induction will only make it worse.
Since Atoyot will never put a diesel in, a supercharged, overstroked, 4cyl would be awesome. HOWEVER, I would admit a refreshed 2UZFE 4.7 V8 would be an amazing addition.
