    I”m trying to increase hP of my 6BTA 5.9 L 300hP to 370 hP, changing my Bosch injectors with Nippondenso pump. I want to know if I need any other modification or adjustment to diesel pump. Thanks

    SIMPLE ANSWER = Not even close to a cost effective change, and that’s if you could even get the parts to do it.. ..And in the end, you are talking 355 HP @ 3000-3150 RPM vs 300 Hp at 2800-2950 RPM.

    Post a seaial number– The are many versions on the older 6BTA 5.9 ND pump M-2 engines..
