TSi Air intake on a TFSi

(1/3) > >>

56OctyVRS:
I have been considering my options with air intakes for my 2.0 TFSi.  I have switched back to the engine cover from an intake kit as I didnt want the intake noise or the diverter valve noise everytime I lifted off the throttle.  I have been contemplating about the compatibility of fitting the OE intake from a TSI as I want to keep the engine looking OE.  Would it be pssible to retro fit the TSi intake onto the TFSi engine?  Looking at it, it should fit and all I would need is a harness to extend the loom to the new MAF location.  I know the OE TSi intake pipe fits onto an IHI turbo and not a K03 so I am not sure about the difference in the size of the turbo intake port etc.  Any suggestions, experience or ideas on this would be appreciated.

Cheers Matt

Sounds like a good project to me, I will be watching this one.  :popcornsoda:

Off the top of my head the size of the turbo inlet on the K03S as fitted to the BWA engine code is approx 56mm O.D.  I can check for you tomorrow as I have a Neuspeed P-Flo in the garage I'm about to try and sell.

Edited size from 63mm to 56mm.

I know the vf engineering intake fir the tsi uses a 2.5inch silicone hose adapter to fit onto the turbo and 63mm is about 2.48inches so very similar. I would expect the parts to fit without any issue. All i would need is to try and borrow someones oe tsi airbox who has fitted an aftermarket intake to see if it would fit. Then see about making a harness to extend the maf sensor.

Hi Matt - interesting proposition, but forgive me as I am ignorant of the TSI intake; what are the benefits of the TSI as opposed to TFSI intake.?

What is the TSI engine - is that the twin charged 1400?

SteveP:
I am struggling to see why you would want to do this?
