i saw an article in Sport Compact Car where they had put a sequential tranny into a Golf. it said that they were sold by Quiafe America, so i emailed then to ask the cost of a tranny for a 280Z. they said it would be between $6000 and $10,000 depending on how much power you are putting out. thats the cost of tranny plus the adapter, but how much would it be to get it installed? would it be worth the money?
