Looks good.

Have you modified the PCV system at all, it looks standard at the moment which would see boost going into the crankcase once your turbos spooled up.

It is not connected in the picture. First drive will be with wastegate fixed open. I have an oil catch can ready for installation before dyno. Before engine rebuild it was just a couple of hoses pointing to the ground making it vent to atmosphere.

It's worth reading into creating vacuum in the crankcase a little more, venting to atmosphere will cause you issues eventually. A vacuum in the crankcase helps the rings seat better, even more vital whilst your breaking in the engine.

I replicated how most OEM systems are setup on mine and utilised brake booster valves to ensure that the gasses don't travel the wrong way.

Pretty much like in the diagram shown here:

Thanks, I will read into it. Currently pcv is connected to factory position as there will be no boost.

Sweet. Enjoy.

@Vtecmec I read the article, interesting solution. However I am unable to do the exact same thing as my air filter is placed directly on turbo housing. Care to explain how you achieved your version, maybe that would fit my situation more?

Btw t is riding smoothly

I have just read through the build, amazing work. Must be the most in depth build Iv seen on a Prelude, it will be like a brand new car.

Do you have any photos of it finished in the sun with the new paint? I want to redo all the bushings on my Prelude as well. It feels a bit boaty at the moment, do you know roughly how much it cost to buy all the bushes needed?
