Some people use the 4x4 oil pump and pick-up pipe with a 2wd sump, but if it's history is unknown, now will be the time to get yourself a new 2wd pump and pipe. Don't forget that when fitting the 2wd sump, you'll also need a 2wd dipstick and tube, as they are different to 4x4. Have a look on ebay for Graham Goode (used ID = RS500_2) for prices.

I believe that the 2wd sump will require modification to clear the engine crosmember. The front face of the bowl needs to be moved backwards an inch or so - you'll need someone else to confirm this distance.

The Escort pinto engine mounts will fit to the cossie block, but you'll need to make up a new gearbox mount for the T5 box.

I think the T25 is good for about 300 brake.
