That final boost sensor on top of the TBB? I broke mine and patched it up but I'm looking into replacing it with a fresh one. Any idea what the official VW/Audi name for it is?

Also, anyone selling an APR bipipe? I saw mosmoes in the classifieds but $300 for a used one is a little steep IMO. The ebay TBB keeps popping off - the fitment of that particular hose is not that great. The hole for the top sensor doesn't have enough extra space to get a hose clamp in well below the sensor. That's not an ideal thing when you're pouring 25psi through that particular part of the intake system....

Are those Okoda Coil packs?

Thanks for the offer but like I said, $300 is a little steep for a used part that retails for $350 new. You had a nice looking motor there - what is that metallic blue thing right behind the n75 valve? Is that an FPR or boost regulator?

donromani

Replying to my own question....I see it's not an FPR as you have one on the fuel line there, so I'm guessing it's a boost reg. then. Were you running stage 3 with a home-brew tune?
