I'm building a B16a2 turbo at the moment.
I'm running a Holset H1 oil fed turbo, but I'm a little worried about it running too hot.
I have bought an Earls oil cooler with an10 fittings and a filter relocation kit.

Should I run the turbo feed as normal, then plumb the cooler from the turbo oil return? Or is there a better setup?

Thanks.

Do not plumb it into the oil return. That will cause the oil to not flow out of the turbo properly. What is your oil temperature? If your sure you want to use an oil cooler then use something like a mocal sandwich block with a build in thermostat.

I've not completed the build yet, so I have no idea. It's more of a precaution.

Do you think I should get it running, and if I have temp issues, then fit it?

you need to go from the block itself. Not from the oil return. that will interfere with the rate of the oil return and cause some serious problems. For most street cars that won't be necessary. What are you planning to do with this?

You absolutely can NOT install the cooler in the turbo oil return line. It is strictly gravity drain and essentially has ZERO pressure. The ONLY way to install a oil cooler is to hook it up to the oil pump in some way. The easiest way is to get a sandwhich adapter and route your lines off that. A thermostatic controlled sandwich plate is preferred. I would assume something of the likes came in your kit since you have a remote filter setup as well.

Unless you are doing some type of racing, it is all unnecessary anyways. Normal driving or even some short highway pulls are not going to make your system catastophicly overheat. Also, all turbos are oil "cooled" and lubricated. Some have the water cooling in addition and is always preferred.

I'm just using it for normal driving and the occasional track day/quarter mile event.

Thanks for the input guys.

Which means its not necessary for your particular needs. that doesn't mean you can't have one, but that it won't really HELP you to have one for your driving use
