I'm trying to offer a 1.6 M-TDI conversion package. I'll get the pistons in 2 months, but I'm still missing the TDI injectors needed. If that product is successful, you might see some extra pump business from it, too. I might need people like you who have time to explain exactly how things work. I get hundreds of emails every day, and don't have time to spend to give in depth answers.
