why not just get the tranny for a ca18det when you order the engine... you can use a 5 speed tranny from a pulsar if its a pulsar with the ca18de in it.... I dont know about the stanza i would try and order the tranny with the engine ..
The only way you're going to get a FWD CA18DET is if you get the 87-88 model that has the intake that crosses the valve cover. The 89-91 models (to my knowledge) all have 4wd trannies. You cannot use the AWD tranny's flywheel with the U.S. spec tranny or at least I wouldn't try. The 1986-89 stanzas tranny would work Good Luck!!!!!!
