There definitely are kits out there: HKS, Forge, 034 Motorsports, SAMCO, etc.; to name a few and tons of Chinese/Asian knockoffs which wouldn't be recommended. Most of the kits are listed for Jetta/Golf; I haven't purchased any, so...I don't know if there would be any differences compared to our cars. I would call vendors first; to confirm before ordering. Here are some links below; tons on ebay as well.
Hey thanks billymade I'll look into that. I saw a few on ebay but most said they would not fit our cars or the beetle 1.8t turbo. It could get expensive to change all the coolant hoses to silicone performance stuff.
