Hi All,

I have an overseas customer with a Mazda BT50 dual cab who's after some advice re. improving performance. Apparently it has a conventional mechanical distributor-type injection pump with manifold pressure compensator and the standard boost is between about 9 and 10.5 psi.

If this is the same as local market BT50s, can anyone tell me if they've had an 'tuning' done on their vehicle and what the results were? The standard boost levels sound quite low for a current 4 cyl. diesel. Has anyone wound up the boost a bit (and subsequently, the fuel) on one of these? If so, could you let me know the details and results?

I am pretty sure the local ones are common rail and therefore not the distributer type at all.
There have been a small number of engine fails with the BT 50's. Camshafts seizing up.

A service manager for Ford has told me that they had one Ranger engine seize up within 1000k's and on investigation there was no oil lubruication hole drilled in the camshaft.

Thanks for the info above.

So, it seems like this overseas model (southern Africa) might still have the engine from the previous Mazda Bravo/Ford Courier?

If that were the case, does anyone have info increasing the boost and/or fuelling on these vehicles? Were the results worthwhile? Any horror stories of motors blown due to over-enthusiastic tuning?
