Alright im running on my 91 TT with arias 87.5MM pistons with eagle connecting rods. So my question to you would be is it better to to run the larger oem N/A(supposedly rated for upgraded TT pistons)oil jets or the oem TT ones? regardless I'm replacing them while I'm in there.

The NA squirters aren't larger, they are angled differently. All aftermarket pistons in a TT require the NA squirters. In reality you could use your TT squirters and carefully bend them to a 90* angle.

^^what this guy said. I wouldn't bend, just buy them if you already in there and ok on money. Im sure someone has a bum engine that may have them used for cheaper, but if going for big HP and a lot of money is alreay in the engine, whats an extra $200.
