LPG kit for Subaru Legacy

Greetings,

What's your opinion for a LPG kit for a '04 Subaru Legacy Estate 2.0 boxer with 150000km on the clock?

Tartarini, BRC, Prins? which you recommend?
It's recommended to use a lub system for it? like FlashLub or LT-Lubricator? are the two the same? I've heard that LT is for turbo models, is it right?


Thanks in advance
