i have a inkling to later on, when i have good money again. to build a tdi golf rally cross car. as a project car for me to learn diesel on. what class would a vw tdi 1.9 tdi be in. if you turn up the pump, straight pipe, and some stuff, you could get decent power for wht it is. 110 hp fly and great torque, its about what a mini cooper non blower has. gwen's car has 116 hp fly. its quick. a vw tdi rally car was down in sandblast once.they were 2wd champs one year.while not as fast as a gas car .it would be ok.so2 because 2l turbo engine.
