Supremacy, what model SW20 have you got? ABS or Non-ABS?
 
I believe the outlet pipes are all on the LH side for RH drive ABS cars like ADM or JDM cars
Pic shows a '92 Supra ABS MC fitted to my'90 model ADM SW20 using a '97 model booster
 
Looks like the pipes might be on the RH side for non-ABS RHD cars - catalog pics seem to suggest that.
 
Non ABS MC pipes might be on the LH side for LHD cars(USDM)
Strange that according to the catalog the ABS USDM MC's are on the RH side.
Bloody confusing hey?? May explain all the different pics.
 
Someone else on here should know if all that is right.

Great!
I have heard some people forget to fit one.
Dangerous, unpredictable brakes without it.

Redtarga, i have a 93 sw20 jdm import. No ABS fitted.

I just don't want to go out and buy a cylinder which then won't fit up to my pipes.

Anyone? Found another which may suit. Image shows correct side for outlets. JB6007 from a 94 hilux/4runner

I'm Running the 1 inch master and late model booster with the BBK 

Mine goes from resonably soft to firm and very bitey. havent had a chance to bed them in fully but will report back next week on how its feeling

I hope you also fitted a check valve on your intake manifold if you replaced an early model booster, since later boosters have no check valve mounted on them like the early boosters.

I fitted the check valve from a V6 Camry on mine abe it works great

With the help of a local brake shop and another forum, JB1882 is the one I was after.
