the stock a15 pump seems to be very good. see bottom of this post for psi details. i figured i would not have much luck finding a higher-flow oil pump so i just went with the stocker.
ill put my shopping list here (docket from repco. double the prices for reg retail cost.)
1 x adaptor-eng.oil cooler 3/4 in x 16 - $49.40
1 x cooler-oil engine 24 plate - $97.55
2 x elbow fittings for cooler - $5.64ea
2 x elbow fittings for adapter - as above
-- get these next 2 from Pirtek or your pref hose outlet.
1.5mtr of heavyduty 16mm hose (i got 300PSI heavy stuff - goes well)
4 x heavyduty hose fasteners
when installing you put the adapter on the spot where your oil filter normally goes, then screw and tighten it on. then put on the oil filter and fasten that on. pipe it all up. start engine and IDLE until u can feel hot oil going through your cooler.
i now get a spot-on reading of oil temp as soon as it pumps back out of the engine. the psi is around 10-30 wait a min ive already said this.

still retaining 10-30psi idle and 40-60 above 3000rpms. The oil temperature took a while to warm up but stayed steadily coming out of the motor at 80-90 celcius while highway driving, and 60-80 while city driving.. all with my 4 speed gbox. (3500-4000rpm highway driving)
im also running a Gemini radiator in there, this little cooler is such a perfect fit, just a few mm before the screw for the headlight on one side and a few mm shy of the radiator on the other side. it takes a lot longer for the oil to reach 80 celcius and i havnt seen it hit 90 yet (need to drive more). psi is basically the same as it was without the cooler installed.
