bugsy 0 Posted April 28, 2006 Report Share Posted April 28, 2006 i think if you look from underneath there is an extra partition used more volume also i think the throttle body linking part of the manifold is slightly different. r u looking 4 an up grade or replacement Link to post Share on other sites
rooneyharper 1 Posted April 28, 2006 Author Report Share Posted April 28, 2006 I'm looking to get my own polished but was thinking of getting one off e-bay as a spare to use whilst my car is having the polishing done, mines a OB2 but wasn't sure what the OB1 fits i presume its older models perhaps Link to post Share on other sites
