had a JDM F22B DOHC dropped in...the car runs fine, just waiting for the correct ecu and hopefully the car will run a little smoother...anyway, if anyone plans on swapping this motor too, wasn't difficult at all...my mechanic didn't have a hard time...the dc headers from the SOHC bolted right on and so did my intake manifold (kept it coz i had extrude hone port and polish it out a couple years ago) if u don't wanna weld a new tranny mounting position, the tranny from the SOHC will fit too...any questions, lemme know..by the way, if anyone can knows what type of cams i can use in this motor...thanks
