all went very well thank god, but it takes hours to do things right to make them look factory.
as for how to proceed with this tb task, I have to remove the plastic intake tube tonight, caliper the Outside diameter of end that connects to current N62B4.4's TB and then caliper the OD of N62B4.8's TB (from e70)... Then I'll look for a silicone reducer/expander/adapter (whatever you want to call it) that can be of very short body and then I'll see if I can connect it.. there IS the small offchance that I may even just need a silicone coupler as I recall the OD lip of that plastic tube is quite large and may be the same diameter as the OD of the... but as stated before, this may not be smart as the restriction now is the factory 4.8iS exhaust and factory sized intake tube from my Dinan air box to my factory 4.4i MAF (non Dinan) and then from that MAF to this e70 throttle body... but thats not going to stop me now in the name of Science from playing this out...


interesting side note, the e53 4.8iS has an N62B4.8A engine and an e70 4.8i has an N624.8B Engine, therefore both have different throttle bodies and totally different air intake systems...SO close, yet so far...
