I have a 2l 16v blacktop zetec in a locost clubman.
What inlet manifold can I use if the standard one isn't up to the job?

Hi, I'm doing the same to my mk1 zetec and still gathering parts. The intake I have is a Rover 220 alloy one with turbo stamped on the plenum, an adapter is required to mount up but is simple to do, there's one on USA eBay now to check out. Another intake is a UK mk3/4 fiesta RS1800 alloy but is slightly restricted in flow.

I have a Zetec turbo cast exhaust manifold and an inlet manifold plenum setup with 46mm Hyabusa throttle bodies also for Zetec. For Sale. PM me for details.
