Hey guys,

So i'm looking to add an oil cooler to my car soon as 90% of its driving is on the track. Thing is I want to add one with a thermostat just as a piece of mind thing. So im wondering if anyone has experience with thermostat oilcooler systems.

I was looking at running a greddy block possibly,

Or possibly a mocal one but im still vastly in the dark at what i'll need.

It's for a b16a2 with a oem oil cooler on it atm but i'll be removing that so what will i need to replace the large block bolt with that currently accounts for oem cooler. Also what is the block thread?

Just so much conflicking information on the internet!

Thanks guys.
