I'm thinking about replacing most of my boost and vac system(hoses at least) I've decided on getting the Samco TIP and other hoses - my question is which kit from samco do I get - if you look at there site HERE you'll see that there are 5 kits that cover the AEB engine - I can rule the first one out from build date and the second is the TIP but the others I have no idea.

TCS60 A4 1800 Turbo 10/1995~12/97 AEB 4 Turbo
TB1360 A4 1800 Turbo B5 AEB/ATW/AWM/AVJ 1 Induction
TCS60/B A4 1800 Turbo B5 AEB/AVJ 4 Turbo
TCS264 A4 1800 Turbo B5 US Spec 4 Turbo
TCS60/A A4 1800 Turbo US AEB 97-99/ATP 00/AWM 01 4 Turbo

I found a site that sells all of these HERE and they are all different prices so somthing is different. I'm leaning toward the TCS264 but its just a guess.

 

I personally see no point in upgrading the TIP/other hosesunless you have a BT or yours is bad/leaking. You wont notice a difference. I could think of lots better ways to spend $150+. Just my oppinion. Buying those is a step ahead of preventative maintnence. I can see replacing all vac lines as they are prone to rot and leak, but anything else i would just replace/upgrade if/when they go bad.
