Default 2.7T engine bay streamlining - EGR, N70 delete

Getting rid of 'stuff' in the engine bay.
EGR/Kombivalve gone (rear hole plugged)
SAI gone

Next: N80 delete. Any good photos what to remove, plug, etc.? DIY write up? Links? Canister stays for now.

Vents (valve cover vent nipples, crank (rear of engine, center, a bit down): seems like 1" (or 3/4"?) hoses. Suggestions/ideas how ot run them (vent to atmosphere, if no other recommendations). 3 hoses (quite big!), run down the side of the tranny (downpipes near by, heat?)?

N249: decided to keep (seems to be consent, beneficial to open DV quicker and reduce 'shock' on turbos).

How to best DIY plug those rear vac nipples below?

Did you get any codes after deleting the EGR/SAI system? assuming that yours is a Tiptronic version from North America.

Default codes from deletes

Yes. Deleting will throw codes. Need to be tuned out or "tricked". Any tuner can handle that.

One is used by the remaining/existing connector. The other one I plugged using a (? 1" or 3/4") coolant hose plus hose clamp over the metal engine nipple, the open end plugged with spark plug (yup) and hose clamp.

Default N75 bleeder hose back to intake

With all the deletes and removal, I am not sitting here with no 'nipple' to connect the 'bleeder' leg of the N75 (not the one coming from compressor housing, and not the one going to the wastegate actuators) that discharges back into the intake (post MAF). Leaving it open to atmosphere may cause 'metered' (MAF measured) air to leave the system (like a boost leak) and might cause problems.

Where can I run the N75 line back into the intake?

Default Valve cover vent, crankcase vent - how to?

Struggling to find a good way to vent the valve cover and the crankcase vent (center, rear of engine).

1" hoses fit over the nipples, but are bulky. And even then: where to run them to?
- Down along the tranny: hot downpipes are right there. Melting the rubber hoses?
- Dump on top of tranny: messy. Build up over time? Hot enough to catch fire?


Playing with the idea of reducing (90 degree sprinkler system reducer elbow) the line, combine using T. Then run on top of tranny farther back and then down?

Best would be to vent into a catch can. Any DIY, photos, solutions where to put the catch can and how to do the plumbing?

Any help, ideas appreciated.

IIRC: on each of the turbo inlet pipes, there is small hard line branching off, coming up the side of the engine/cylinder heads. I plugged them up, thinking they were lines from EGR or other recirc stuff. Are those (via a T) going to the N75 discharge nipple?

Could I "T" into this one on back of engine?

Yes. The N75 uses those to sense pressure differentials, and unless you figure a good, and i mean really F#%^in good way of doing that, you will not be allowed to break 4-5psi boost or whatever it is that the waste gate mechanically governs you at. This prevents turbo "free spooling". Which would grenade those little fellas in no time………… I think. It's early and no coffee yet…… I

P.S. I like your style McGyver!
