I used an XS power nissan 200sx manifold on my zetec turbo, i cut the flange off and had a zetec one welded on.

you deffo need to brace them well, as well as the top id seriously consider fabricating a brace to hold the turbo from underneath aswell.

mine was absolutly fine for the 200 miles that it was in the car before the pikey cunts wrote it off.

it made 397bhp/386lbft so done the job for what i wanted.

admittedly the welding on the inside wasnt great, but it done the job and took a T4 lol
