I've been drooling over the APR Stage III+ turbo kit for my car. I won't be able to afford it until late next year or the beginning of 09', but I was reading the price list and saw that in 2003 they made both VVT & Non-VVT 225 TTs. I don't have the Bentley manual yet for my TT. Is there a way to tell if the car is VVT by any other means than the VIN?

 

what is your engine code?

 

by your ecu would be the easiest. you can call the people you got your chip from or check yourself

T3100016 - non vvt
T3100017 - vvt

 

I found on AudiWorld.com a posting that shows which engine is which. If the cylinder head has the codeAMU on the lug on the drive belt end of the head then it is a Non-VVT engine. If on the other hand the code is BEA then the car has a VVT engine. My car is a VVT car. Nice to know and it explains a little as to why the engine seemed a little more responsive then other 225s I've driven that were older cars. I thought it was my imagination, but guess not.

 

vvt is NOT a performance item like vtec or vvt-i. It is ONLY used at start up and for emissions. Still not sure for the 225's, but for all the VW's and 180's, the vvt all have wideband o2's and the non-vvt are all narrowband cars.

 

you are very correct cincy

 

Heh... Performance.

 

I don't understand why then the dyno numbers for the APR Stage III+ kit have higher output for the VVT cars. What would be the differentiating factor?

 

thus better tune capabilities

 

So a vvt car is a little better, and what does vvt stand for.
