Strength of Toyota gearboxes	Fri, 01 November 2002 12:08

Strength of toyota gearboxes Hi, Does anyone know how strong the Toyota W5* series gearboxes are, in terms of how much horsepower they can take and how much abuse (it is going in a rally car so it won't be gentle). The last mazda box died a horrible death on an unfortunate night. The car is a RX2 rally car with a very large bridgeport (~220 hp) and hilux diff. It will have to take some abuse obviously. The boxes I am mainly interested in are the W55 celica steel case and the W58 supra. Ideally I would prefer a W57 (provided it is strong enough) as it has a better overdrive than the W58. Also any information on the strength of a W50 would be appreciated as well (although I get the feeling it may not be strong enough) While obviously the supra box is the choice (I know they are extraordinarily strong), the W55s are cheaper and more readily available (any particular W55 as we have one from a 2S sitting at home?). Thanks [Report message to a moderator]
