Im rebuilding my zetec turbo in my S2 escort RST.

First of all, if i fit a mk1 focus RS exhaust manifold, will it work, i think i will just need to make a flange to meet my escort downpipe?

Also, i have been offered a GT30 67R Duel ballbearing turbo. its currently on a Nissan Pulsar... Would this turbo fit in the focus manifold?

At the moment i have a stage 3 T34 Turbo on the CVH manifold with an adapter plate for the zetec head.

i want a lot more power at the end so i need a bigger turbo anyway, and i dont want to use the cvh manifold, i want one to go staright onto the zetec head.

Anyone know what i could do?? Cheers in advance...
