1990 CTD 5 speed Getrag,all gauges,4" stacks mounted horizonally(sidepipes),working on powerjoke I/C,BHAF,no screws turned yet,mallory pump running B100,turned 500,000 still smokin',more as the penny roll in.

I don't know anything about this engine, but a simple way to increase power is to set the injection pump a little bit to the rich side. Disadvantage is developing smoke.
If you have a turbo, a manual boost controller like the Forge Munos is a cheap way to increase horsepower. More fuel+ more boost= more power

If you want more and you have a turbo, simply add an intercooler or one with a bigger core.
As you can see -you can go in steps and as money allows.
