Ok, i've started my Drag 3 install.
I have a few questions.
1st- Where does the coolant feed tap into the turbo?
2nd- I ordered new RC 370 injectors, but they don't plug into the stock injector harness, is there something else needed to plug these in?
3rd- On the turbo theres the oil feed line hole, and the oil drain hole, but there's also two other threaded holes on the casing? What goes to thes??

Thanks, i'm sure i'll have many more questions.

 

you need rc clips for the rc injectors

also, you already have a thread about this
no need to start another one...

 

Drag3 comes with an oil cooled (only) turbo.

You'll need some OBD1 injector plugs.

Ben answered your third question in your other thread.

 

u can also use clips of a domestic, v8
