B20 turbo- what to do with PCV ?
My setup consists of b20b (1996), this motor is going to ran on low boost 6-10psi. With low boost what should i do with the pcv system, whats the easiest and cheapest soloution.. Im going to be running the valve cover breather to the atmosphere.
Keep the stock pcv system, untouched or take out the pcv, run it open to the atmosphere and block the nipple on the IM? I know that i will get crapier gas milleage, and that this is illegal, and it wont pass emmissions, but i dont care about all this.
Whats would be best for my new engine,?/?

whats best for your engine is to have a vacuum source at the end of your crankcase vents.
What I would do, is use the stock pcv hose (with no valve) run it to a catch can, I would also remove a 14mm hex plug in the back of the b20 blocks, install a fitting for it, and run another breather to the same catch can, then i would find a vacuum source for it. Either pre-turbo or exhaust slash. Or if you want to spend big bucks get a breather catch can.
But the cheapest solution is to unhook the pcv valve and block the vacuum port I guess, but this is not the best for your engine.

I dont want to spend big bucks lol im broke as it is with university.. IF i leave the pcv system alone, it would close when the motor sees boost right? Preventing boost from entering?
what about if i leave the PCV connected and vent the valve cover one? Going to be running low boost aswell.

i doubt they add horsepower, but i do know for a fact that they work and work well.
And by the time you add up everything you need for a catch can it'll prolly cost around the same.
I'll most likely be buying another krank vent mini system for my boosted CRX.

i just odered mine, shipping was like 15 bucks, http://automotivespeed.com.. better than running 5 feet of lines and a catch can, cluttering the engine bay even more lol, imo

I bet many ppl dont even look at the pcv when boosting their cars considering theres tonnes of boosted cars on here, and like 4 ppl replied with what they did with their pcv lmao, something so simple but vital to a engine.
