Here's the situation. I have a 1990 S13 with SR swap. I re-used the SOHC air conditioning compressor by means of a ghetto-rigged bracket; it's always worked fine, UNTIL last year when the tensioner pulley seized and burned up. I mean literally, the paint burned right off it and it broke the belt.
The pulley I sourced to replace it has recently started to squeak (yes, I do know it's the tensioner pulley and not something else). I'm starting to think that the "custom" bracket doesn't hold the compressor where it should be - not that it's loose, but that when everything's put together the belt isn't in exact alignment, which puts some kind of undue stress on the weak link, i.e. the tensioner pulley.
Editorially, this doesn't surprise me; this bracket was made by the same guy who screwed up my wiring harness for the swap, so if it's not right that would stand to reason considering the source.
But I digress: here's my question. Let's pretend that I source a DOHC S13 A/C compressor, Codyace's bracket to mate it to the SR block, and the appropriate lines. Will the lines bolt up to the rest of the components in the car? That is, will the big hardline bolt up to the fitting in the firewall, and will the smaller hardline bolt up to the fitting on the condenser just behind the driver's side headlight bracket, or are the SOHC and DOHC A/C systems completely different, which would mean all new lines, dryer, condenser, etc?
Obviously I'd have to source the parts, have the system evacuated of coolant and then re-filled with the newer stuff (R134, right?) when finished, but at that point it'd all work, I think. I have an SR compressor but no lines, and I don't have a means to have those lines custom-ed up anyway to work with my chassis.
Any input appreciated.
