the 2.3L quad 4 was designed by oldsmobile way back in the 1980's...
the hottest version is the W41 model which was a limited production. if you go to
http://mantapart.com you can pick one up...
W41 made 190hp... it's spotted by the logstyle intake and red IDI cover (type r man type r
) the IDI cover says OLDSMOBILE on it
the other version is the 2.3HO which is spotted by the HIGH OUTPUT 2.3 quad 4 cover... it came in 180hp and 185hp variants..
these were higher revving than your regular quad 4 motor, and were good times..
the OLDS achieva I think SCX model came w/ the W41.. I duno I need a quad 4 genius to talk to me so I can get this info down like a historian.. but there were models that had a 5spd tranny w/ a limited slip differential..
definately good times had by all.
