You're right, the T5 is a Borg-Warner. They are good for up to about 300 hp or so, according to the several web sites I've visited. And the WC T5 is supposed to be the better one to have. Gear oil will ruin them though, as was the case with my first one. Someone had put gear oil in it, and the lubrication holes to the gears themselves are too small and the gear oil is too thick to flow properly, so lack of proper lube shortens their lives. The second one I have had ATF in it like it should have, and shifts better, with the exception of second gear, which has a weak syncro. If you can find a S10 with a diesel (were they available anywhere else than North America?), then you will have a bell housing to fit the BW tranny. I understand the T56 is a 6 speed T5. Hmmmmm. Supposed to have the same dimensions as T5.
Has anyone ever heard of a different camshaft for this engine? I thought I read somewhere once that a cam was available to increase low-end torque (is there any? <img src="/forums/images/graemlins/rolleyes.gif" alt="" />). Also, while I'm full of questions, has anyone heard of the N/A C223 breaking rods? I know now the turbos did, but mine?
