The 3B is no powerhouse but it is a reliable, simple mill. Unlike the 2LT(E) the B series is a light truck motor so they will go forever if given standard maintainance.
It's turbocharged, direct injected brother 13B-T is the one to go for if you want power.
Ive had 2 3bs one standard and one with a aftermarket turbo,both engines just keept on trucking,the turbo is well worth the money(seen kits on trademefor $350 plus exhaust) never had to touch engines and they have no computers e,t,c, so you dont have to worry about it getting wet.
