Structure Audi 80 B2

Moin, moin I am now proud owner of an Audi 80 Type 81 😀 picked him up today and can’t wait to get started. Since it’s my first project car I have a few questions (maybe you can make some decisions for me 😉 So Bj. is 1980 so he would be old enough for an H license plate, I would like to have a few more information or if it were possible to set up the car so that you could drive him as a cutting racer, I’m not yet conclusive so what do you think? here are a few things I would like to know Motor: Original for H-marks or which engine would offer itself for a racer Interior: Original or empty concept for the race track (cage, shell seats etc.)??? Rims? Brake? Grill: best look at the grill on the photo (there are other grills that fit in there Audi 90/Passat???) I thank you already in advance and hope that I can put in pictures of the setup 😉 PS: maybe he sees off like the Audi on the second picture.
