While I have my favorites, as a Toyota enthusiast I cannot possible dislike the JZ-family. In fact the highest amount of horsepower our H.D. R-series transmission has experienced on record without failure (yet) is during a 1,240 horsepower dyno run of a 1.5JZ-GTE running an 82mm turbo. (I say 'yet' because our transmission
will blow up.) Our success behind JZ engines without a doubt helps us sell transmissions to the drifter crowd.

What I don't understand thus far is if your truck is not a dedicated Rock Crawler, then why would a 4cyl transmission with only a 3% lower 1st gear ratio dictate it's preference over one much better suited for a 6cyl engine?
As for extra zip and raspy notes of high revving performance engines, my daily driver is a 1.59-liter Supercharged 2,300 lb Toyota MR2 with a 6-speed Lotus Exige transmission that currently makes 158 HP/liter. That is equivalent to a 1JZ making nearly 400 HP
