Need help finding the right clutch setup

I've got a 2002 A4 with the o1e trans and the motor is a bhw from a Passat. Dmf was destroyed when I bought it so I've got it torn down and currently researching what to put in it. The car has an upgraded turbo and was running 25psi ish so I know it's not stock hp and torque.

Looking to stay under $800 for a dmf/clutch/flywheel but really just need some insight on what will fit. So many setups say that they only fit specific motors.. but I was told that it had a 1.8t clutch and dmf in it so how vague is "specific fitment"?
