dont turbo tecniks make one.. but you can make one your self. http://www.realpower.dk/

i know that the link are in danish. but i eksplanis perfect how to build a manifold your self. on the page theay build it for a toyota cupe. but the princips are the same. and in the examble there are stuff fore abaut 50 pounds. so if you cant weald and cut stuff your self tehn there problery peable arround you there can help you. the pipes and bending theay youse we call steam pipes. dont know what you call them but theay are with a thick wall.

the cheapest way to build one are to youse the std one on the dohc
engine and put some things on so the turbo fits.

but when we talk turbo/kompressor on a dohc engine then dont go ower 200bhp or 0,7 bar on a std engine. and get a good ECU. something like a megasquirt or better. depending on how deep your pockets are.
