i was given a b series oil cooler/warmer off a mate for free so set about fitting it to my jdm b16a which didnt have one.
Image

so first thing is to remove the oil filter and you will be left with the filter holder
Image
this will need removing from the block as the cooler needs to be sandwiched between the block and the new filter holder

i didnt want to damage the threads but its going in the bin anyway
Image

removed

Image

cooler kit
Image
just to the right of the filter housing is a 14mm bolt (on some this may need drilling and tapping if no bolt is present)
Image
this coolant return adaptor will take its place, its 22mm
Image

next step is to remove the thermostat housing, its held in place with 2 10mm bolts
Image
this will allow the coolant 'tube' from the water pump housing to be with drawn

tube removed
Image
nice new waterpump:)
Image



the old(left) and the new(right)
Image

when refitting the 'tube, i recommend using new o-rings (x2), they are a couple of quid from a honda dealer, when refitting add a bit of vaseline to the rings to help then slide in easier (oooo er) refit the thermostat housing.
and it will look like this
Image

now the cooler can be installed using this, this sandwiches the cooler to the block.
Image

now fitted
Image

now for the coolant lines
Image
Image

and that is it, stand back and admire,
