2.0 cvh?

Post by Jhdelta » Mon Sep 17, 2018 6:09 pm

any thoughts on this for a ss1 and where the bottom end is from

oil pump / filter set up loos odd and possibly foul mountings and the dip stick on the exhaust side should make it fun to check the oil when the engines hot!

Zetec bottom end, I think.

It’s a ZVH - CVH head on a Zetec block. Used to be popular because the CVH head has massive valves / ports so works well in turbo applications, and the zetec bottom end is strong. You could also retain all the cvh turbo bits without needing to make new manifolds etc.

This one looks like it comes with an escort RST T3 manifold, Fiesta RST T2 manifold, and an escort RST MFI manifold - also has turbo oil feed / drain so suspect it’s got a compression suited to boost.

IMHO, fit the entire zetec if staying NA.

thanks

regs dictate period engine though should be ok with just a bottom end but not a complete zetec.

if zetec standard pistons will it be low compression for turbo as you say?

SS1 was out of production when the Zetec was introduced. It should be LC but may be pistons or just a decomp plate?

Zetec generally has flat top pistons and with an early (true) hemi-head you generally end up somewhere Between 8:1 and 8.5:1 from memory - about par for turbos of the era and up to 1bar of boost which handily puts you at about the max bhp the stock bottom end is safe for (230-240). A bit “redneck” these days but you’re comparing it to the KE-Jetronic injection used in the Escort..

What events / series are you competing in? Be careful with engine swaps in competition cars.

It's quite easily identifiable as not a 1985 cvh so I would proceed with caution given your intended usage!
