as for the del sol question. . . . no
as for the b series question. . . yes and no, it didnt fit on my car simply because of my map sensor was placed on top of the throttle body, like the 2nd gen fitment. I could have simply changed my throttle body, but i didnt see a point in taking off my 68mm for a 58 or 60. Kinda get my point?
HOWEVER, if the map sensor is on the fire wall and is ran off of a vaccume line, like all obd0 cars, it'll fit just fine, even with a b series.
