My Fast Road Sierra inlet manifold build

Post by berkut »

Hello Everyone!


I'm posting a few picturess of my inlet manifold during the build.

The engine in use is a Ford Escort RS2000 inline 4. The head slightly ported (ports are sanded with 80 grit, all ridges removed, seat matched, a few geometry tweaks for higher flow, 3 angle cut, deshrouded valves, chamferred the combustion chamber ), new OE valves, guides, lightweight OE mahle pistons are fitted. Right now OE cams are used with 10.7:1 compression ratio. Everything is converted to be installed in my Ford Sierra 4x4.

The inlet manifold length is designed for peak horsepower to occur at 6000rpm.

The almost finished product. Needs a few more layers on the air box and the throttle body interface plate to be glued on.

The styrofoam mold for the air box. This is wrapped in cellulose foil before making, which will smoothen it and reduce the sharp turn on the short side radius.

The almost finished lower part of the manifold. Only velocity stacks need to be added, currently there is only a small chamfer.

The gutted OE manifold. Normally it forms a C curve, the lenght is about 35cm stock, 12cm modified. Its a straight piece, tapered inside D piece of pipe. The ends which will be glued are machined with a diax for extra roughness.
