Okie, who started this thread? i think you need to learn how to speak english then get shot.
Ebay/hyundai will be your best bet. there stock turbo manifold failed with the orginal power output so if you going to make big power i suggest you get a custom one made. if you you can pick one up for dirt cheap and it will get your project mobile then go for it. but it will need to be replaced. ive been doing turbo for 10 years and all stock cast manifold fail.....
I have put up many differnt scoupe turbo manifold design/blueprints so use the search option and im sure you wuill be able to make the decisions for yourself. here is a more intimate scoupe/turbo forum
