Type E and Type-9 ra­tios

Classic Ford - - CF TECH -

Can you clar­ify Type-9 five-speed and Type E four-speed gear­box ra­tios? I’ve heard it said that the four-speed ’boxes have bet­ter ra­tios, but oth­ers say a five-speed Type-9 is the same as a four-speed but with the over­driven fifth gear.

I’m build­ing a 2-litre Mk3 Capri and have a Type-9 five-speed, but have been ad­vised to use four-speed RS2000 ‘box. Can you help?

A The RS2000’s Type E four­speeder has ex­actly the same ra­tios as the Type E found in the four­cylin­der Fords of the era, and again the same ra­tios as the Type-9 five-speed (though lack­ing the over­driven fifth gear). The 2.8 V6 ver­sion of the Type-9 ‘box has slightly bet­ter ra­tios, but fit­ting one of th­ese in­volves ei­ther ma­chin­ing the in­put shaft or swap­ping it for the four-cylin­der ver­sion, which is a job for a spe­cial­ist such as BGH Geart­ech.

The RS2000’s gear­box could be spec­i­fied with closer ra­tios (of­ten re­ferred to as Rocket ra­tios). Th­ese aren’t nor­mally found ex­cept in orig­i­nal Ford Ral­lye Sport ‘boxes or as af­ter­mar­ket gear­k­its (again from the likes of BGH). Up­rated gear kits are also avail­able for the Type-9.

Given the choice, we’d pre­fer the Type-9 in a Capri be­cause of its no-fuss fifth gear cruis­ing and mo­tor­way econ­omy, and a drop to fourth gives a nice ra­tio for mo­tor­way over­tak­ing. If you can af­ford to have an up­rated gear­kit in­stalled, then even bet­ter.
