Redtop engines

There are 2 types of this C20XE engine available - the very early 'Coscast' head ones which apparently don't suffer from the porous head problems that the later ones can suffer from. These engines are 150bhp standard.

Of course there are the C20LET turbo versions (approx 210bhp) as well as the not so good Ecotec engines which have a measly 136bhp.

The Coscast head versions of the C20XE engine can be distinguished as the non-cosworth head has a core plug in the back (in a manta) and the cossie ones have a big casting rib here with no core plug, also on the head to block flange on the exhaust side on an overhanging part of the machined surface there’s the word 'Coscast' stamped.

When doing this conversion to a Manta B series check out this link for a full how to breakdown.
