www.powerheads.com. they have the conversion with everything you need for 1,495.00 and 2,595 fully ported with ssvalves and all the works. There are a few other places that do them but may be more expensive. The DTA guys seem like they got in over there heads. How could they sell a fully ported kit for the cost that everyone else sells the unported kits for? They got in trouble and sounds like they screwed a few people. Also, the unported kits are good for 45 - 65 hp and the ported kits are good for up to 100 hp, at least that is what they claim. Any way you look at it it is still the cheapest mod for the hp gain you get.
