Simple question but the answer eludes me: It seems for non S3 1.8T's there are two TIP variations. I have an AJQ engine, there is another for engines such as the AUM. What is the difference? Forge list two with the engine codes:
AWW - AWD - AWP - AUM - APP - AWU - AUQ
AVC - APH - AJQ - AGU - ATC
What is different? Is it the ko3 or ko3s turbo having slightly different inlet diameters? If that's what it is then i'll buy a specific one for my engine, if it's something to do with the various ports then maybe some pipe rearrangement would mean either would fit? And I could buy either when one becomes available cheaply, as the AJQ is a rarer engine.
