OK thanks for the quick reply. JDL has some good pics with a removed engine that show the layout exactly. I will take a look at them with this info.

Can you link me the exact pics? I'll make an educated guess based on them.

These are the best I could find. The removed engine ones only show from the bottom.

I'm 95% sure it'll clear

Anyway checking back in from my track event. I now need new brakes. The new found speed has me overheating them in less then a lap lol!

If you're in Houston would you mind meeting up someone so I can see/hear how the sc feels and sounds?

Anyone have or know someone who has a JDL or other EL headers that pipe up by the pulley system?

Just get the HKS EL

Don't really like the sound of the HKS or any UEL I've heard

EL = what OEM piece is
UEL = Subaru burble...sounds rough, but it's not quite necessary for the SC guys since the torque dip is already eliminated with the SC.

This. Like I told him, it is his decision to make whether he wants to run a vented or a non a non vented/check valve to keep from pressurizing the crankcase when in boost.

Yes, it originally was designed for emissions, but just like EGR, it was found to have other benefits.


Reroute the PCV system like a normal turbo car and you won't pressurize the crankcase

PCV valves close at wide open throttle, the "benefit" you're talking about isn't quite what you're making it sound like.

There are a whole lot of turbo cars out there that have functional PCV systems and still blow dip-sticks out under wide open throttle.

Actually preventing pressure build-up in the crankcase requires a whole lot more venting than you're going to get from either one of the catch cans you guys are talking about.

This car doesn't come with a PCV valve though. It just comes with a hose barb threaded into the crankcase, a rubber line, and a nipple on the back of the intake manifold. You either install a check valve to prevent the crankcase from being pressurized while still allowing the crankcase to vent during vacuum situations or you install a VTA catch can and don't allow the crankcase to see any boost or vacuum. I am fine with either solution, but I prefer the VTA so that no hot oily air has the chance to go back through my intake manifold and engine.

I agree with you on that. Didn't realize these cars (or any for that matter) don't actually have PCV valves.

For turbo applications especially I'd rather have it VTA than give it a chance to coat the inside of my intercooler with oil. (No oil separator is 100% efficient)

Look at a Supra and say that all again No PCV valve, but the system runs to before the turbo and to the throttle body and effectively switches over whenever it's needed.


If you're blowing the dipstick out, you either have a clogged system or massive blowby (all the dumb kiddies putting filters on their valve covers because it happens on their 200K+ mile motors and saying PCV sucks)

You're ignoring the third solution (and a fourth, but using venturis in the exhaust is dirty as hell and would destroy a cat and fail any kind of inspection).

The small amount isn't going to cause any issues. When I pulled off my intercooler and cleaned it after 20+ years nothing drained out, I had to use solvent to get anything out and even then it was minor.
