HRH Posted January 15, 2009 Report Share Posted January 15, 2009 Yes, it is a rarer closed chamber. The last one I sold was anyway. I think it's fairly small ports though, if I remember right, though that can be fixed easily. Quote Link to comment
banzai510(hainz) Posted January 15, 2009 Report Share Posted January 15, 2009 all infor here. http://www.olddatsuns.com/ W53 is a good head, but needs to be ported out if you have a bigger intake. Quote Link to comment
Jason Posted January 15, 2009 Report Share Posted January 15, 2009 It'd be more desirable if it was already notched for fuel injectors too! Nice head otherwise though. Quote Link to comment
Roman Tasel Posted January 16, 2009 Report Share Posted January 16, 2009 speaking of heads, are w58 heads rare? Its on my 620. Quote Link to comment
RacnJsn95 Posted January 16, 2009 Report Share Posted January 16, 2009 speaking of heads, are w58 heads rare? Its on my 620. Closed chamber W58's can be rare, but they are still a round exhaust port, with the emissions liners, which most people tend to stay away from... I have a W53 that's notched for injectors, and has both the EFI, and Carb manifold bolt pattern in it, jdm L18 efi head. Quote Link to comment
datsunaholic Posted January 16, 2009 Report Share Posted January 16, 2009 Roman, Closed-chamber W58 heads are rare. Open chamber ones are extremely common as they were one of the stock heads on L20Bs from '78-80 model years. Quote Link to comment
datzenmike Posted January 16, 2009 Report Share Posted January 16, 2009 Had a closed chamber W-58. It was from a '79 200sx. (Canadian) Had the exhaust liners too. Quote Link to comment
Jason Posted January 16, 2009 Report Share Posted January 16, 2009 I am running a W58 head on my L20b in my wagon right now, just passed aircare (smog) with flying colours too! I swear that the liners help! Quote Link to comment
Roman Tasel Posted January 16, 2009 Report Share Posted January 16, 2009 its on a 74 l18. Quote Link to comment
