Sorry for not getting back to this. Personally I thought the IS38 was perfect on my GTI. But a smaller hybrid like the DBV2 V1 or EQT standard housing sound like they'd be good choices for you too. I'm not familiar with the TPC20 that others are recommending.
Had another track day Saturday and wanted to share this picture, lol:

Typical PCV oil surge issue, seems to have been made worse from the Wortec oil pan. More oil sloshing around. I might try the iAbed baffled pan which claims to help with this issue.
Or, I might start parting out the car. I'm walking a fine line right now... thinking about picking up an '18 Camaro ZL1 1LE while prices are down. 650 supercharged bald eagles and track-ready completely stock from the factory... Very tempting to me right now as I continue to have issues. Having more wastegate issues as well... fantastic.
On the upside my cooling improvements have definitely worked, so there's that!
