It's all in the trans. You can do the 8 valve motor from the cx or the hx any d series but source a cx/vx trans. 40+ in my cx in summer. You could always get a 92 vx in Canada I think that was the only year they were available there. Or you could import one from japan or USA.

Never bought from them but heard ok stuff about them.
