What turbo are you using? If it's not a ball bearing ditch the restrictor.

If its still leaking/smoking with the CCV vented to atmosphere and a proper oil feed/drain then the seals are shot.

ah, there's your problem, ebay turbo. The seals are probably shot. They're not ball bearing.

Do yourself a favor and hit up ebay, not for more ebay china chargers You can probably find a decent or even new rebuilt Holsets for 200-400 bones which is a bargain. plus they are indestructible if taken care of.

an H1C or an HX35 is what you want.

I think it would make more sense to put your AFM before the turbo.
It would make even more sense to convert to a standalone EMS so you can ditch the AFM... that's what I'm going to be doing very soon.

The difference is how the stock ecu will handle the incoming air temp and the pressure waves on the barn door . I have tuned both types and both setups have disadvantages and advantages.. In a ideal world you would want the air temp sensor after the intercooler and the barn door flapper before the turbo but of course it's not easy to separate them... When the stock motronic is tuned correctly it will handle bigger injectors and boost with out any problems no matter what way you run the AFM

Hey you tune the stock motronic right? Any chance you've gotten the ignition tables from the 179ecu?

The AFM is designed to work under atmospheric conditions, as soon as you have boost the door in the AFM is just going to be pegged open. The car will still run with the AFM down stream from the turbo (my car is currently set-up that way for the time being). It just makes more sense to me to have it before the turbo

edit: plus what bmwconnect said

The only real problem I ever had with my push threw setup is heat soaking the AFM and lean idle start but editing the software changed that quickly.

So you never found that the door maxed out when under boost? because I could see that happening very easily.

Yes all the time, but only in boost and in that situation the throttle is open more then 50%-75% or even close to wot so you just treat the high load pt map like a wot map

Makes sense. Not ideal but that should work relatively well. I'm guessing Alpina did something similar with their old turbo motors.
