Questions installing turbo kit

[BOOSTEDM3]

AA claims that on this particular setup,the adjustable fuel pressure regulator is not needed,however,here is on installed,I have the exact same one??:



Out of curiousity,what are the 2 lines running into the intake piping,obviously,one is the breather for the valve cover,but what is the other line,& where does it come from??:




Sorry,I don't know how to make the arrows that you are looking for,however,the lines are very visible in the larger pictures...

Post bigger pics with arrows pointing at what you have questions with. The two thin hoses going to the elbow near the throttle body are for the water/alch. injection

If those hoses are on the intake side of the turbo... they are probably for the bypass valve(return for spoolup) and the other hose is for crank case PCV

If AA is building a 550-600hp+ turbo BMW, then an external fuel pressure regulator is necessary.

I do know that the smaller(closer in pic) of the 2 lines is the breather from the valve cover,however,the larger of the 2 is the qurestion...I believe that it is the PCV that is venting back into the intake side,because their is a 2nd line that comes into the factory intake at the same location,but since you are now relocating the intake to the other side of the engine bay I'm trying to figure out which line it is from the backside/bottom side of the engine
My setup will be right at the 550hp mark,so that's still the question,do I need to run the adjustable pressure regualator,AA claims that I do not,& why do you need there,but not any lower hp??Is that because of the chip not being able to read outside of it's parameters??
Is there anyone out there that has done this on their own,other than spend a fortune & send there car to Active??I've seen pics/website of Jim Powell,who has done extensive work/research,but cannot reach anyone at this particular website.I've got body work,custom paint/roll cage & the custom turbo/kit for the same price that they are advertising their entire kit for.& the kit does not even include the clutch/flywheel kit,& other upgrades that have been done to the brakes/suspension.
Now,don't get me wrong,Active has been a huge help in the whole project,I'm just trying to help us all out in accomplishing the task in my garage @ home without a lift,& pass on the good news/information...IT CAN BE DONE!!!!

yeah I think 550hp can be obtained without the external FPR. You may only need the right sized injectors and a high flow fuel pump.
I've only seen them on 630hp+ BMWs. I thought I saw one on a 550hp M3 but was mistaken.

Good luck with your setup.

if your referring to the last pic, i believe that the 1st hose is from the valve cover(crankcase) and the other hose is from the BOV venting back into the intake.
