I am looking to build an off road racer with a 2015 R18 engine.

I need to know a few things like:

1) Where is the Vtec Oil control valve,
2) What is the coolant flow diagram (including heater core direction and TB coolant direction, etc.)

Maybe these would be in the service manual, and if so where is the best place to get one?

Thanks!

I am still hoping someone can help me clarify the coolant flow on a 1.8L R18 civic engine.

I there are 3 separate housings that are attached to the head. Each with several coolant ports that come off of each housing. I have them circled. One in Red that I believe take coolant from the radiator in to the engine. The other circled in yellow, I believe send water out of the engine in to various components like the TB, etc

Just looking for verification as I am plan to tap in to one set to cool a turbo, and I really want to get it right.

Thanks.

holmesnmanny, how you been man? Trust you have been well.

Sorry, I was referring to a 'Free' one, as there's one for 7th gen Civic.

That's why was asking for a .PDF copy of a shop manual or anything along those lines.

As always, thank you.
