I bought a 91+ oil filter housing but I want to run an air cooled setup. I don't want to sell this thing and buy a 90 housing so I looked into getting one of the adapters. Does anyone run one of these? If so where could I find one for a good price, but be a trust worthy source?

Thanks,
Steve
 
Sorry to bring this back up, but I was doing some reading on oil coolers, and 91+ would need the 89-90 housing.

I did a search on "sandwich" and this was the only thread that came up. It looks like an easy way to add an oil cooler. But is it effective?

Is it possible to remove the stock water cooled oil cooler and attach the sandwich, or is it unlikely because the sandwich sits in between this very thing. And only way would be to seal the coolant lines towards the stock water cooled oil cooler?

They look nice?

CNC machined cooler plate that installs between your engine block and oil filter, your oil lines hook up to the plate to then go to the oil cooler core. Plate has two -10AN fittings and also two 1/8" NPT machined ports to accept oil temp or oil pressure senders or turbo oil feed line or any source of oil needed without having to tap into the block . Two block fittings will be included, only one is needed but two are included, if you wever swap the cooler kit on another car these fittings will be usefull due to different size block fittings on various cars. The plate has an angled design for the cooler ports this allows better clearance of oil lines.

Thoughts?
 
I spoke with a rep from Greddy and he said that the way I had it (Oil filter>Sandwich>stock cool>filter housing) was correct and it will not harm performance.

aside from the fact that you push the filter even closer to the downpipe, which is a problem for many of us.

honestly, if you want to be cheap and not buy a 90 housing, pick up a non turbo housing for like $5 and use the sandwich with the filter. It gives you about the same size packaging as the 91+ setup, removes the water disaster and does the oil cooling. Don't forget that without a 1990 setup you will REQUIRE an oil thermostat because without it your oil WILL get too cold around town and on the highway. You want the oil to stay ~180*

Unless you keep the stock cooler. You can also use the 1g oil filter, because it's not as long, just fatter.
