Dude, all Preludes from 92-01 had offshoots of the H22. Either they were the H22B1 or B2, with either the OBD1 ECU or the OBD2 (97-01 models). All were DOHC VTEC (hmm, if people didn't know what H22's and type R's were, who knows how VTEC works?). Only difference in the BB6 series was the Type SH (stands for Super-Handling if you didn't know), which had a limited slip and came in only manual, not manu-matic.
No 4WS on this generation, at least not in the US. 4WS on the JDM Prelude BB6 as well as it's european counterpart had 4WS. The BB5 was the last US Prelude to have 4WS.
Great car, and the Milano Red is a great color! Mileage is a tad bit high, but an engine swap or head rebuild would make it new if any problems arise. These are great project cars, and great cars that take you back to a simpler time where oversized dashboards and digital speedometers didn't rule the sportscar world.
Sorry if I didn't contribute, but I felt the need to educate some people about their cars. Ignorant remarks about cars that have the potential like the Prelude does is unacceptable!
