#286465 That's how it is from the factory, with a check valve in the line. That's so the intake will suck vacuum from the crankcase at high rpm. With a turbo spooling, you no longer have vacuum but pressure instead so the way honda designed the vacuum system to work no longer matters. So now you need to let the crank case and valve cover vent by means of a vented catch can. So remove that line and put a cap on the nipple on the intake - it's no longer needed since you're running a new line to the catch can.

It's really not any different :thumb: You'll have a different manifold and probably a little larger turbo.

I'm not sure about the carb setup, since we never had them in the states on 5th gen civics. The fuel management will be the big difference. Also there may be different sensors too.

Yes, mostly everything in this setup will be the same for the D16y8. If it's in an OBD2 car, you would need an obd1 conversion harness to run a chipped OBD1 ecu.

#321522 This is a great write up. This is my first build of a NA motor that I will be doing. I have built my wrx and made 452whp and 469ftq but never taken on a project like this. Any other tips for drilling into the oil pan? That is the only thing I am nervous about

I can definitely say that this is one of my personal favorites. :thumb: :thumb:
je.

U def don't want to use Teflon bc when the oil heats up, it will start melting and trash will get into the oil lines. HondAbond ftw. Most flare fittings don't even require seAlant.
