Get 300hp!

[Caseyadair]

Hey guys new to the forum and to first gens. I just bought a 1993 12 valve with the 47rh transmission rebuilt heavy duty. Kdp addressed has all the gauges. Steering is taken care of. It has a 4 inch lift and 35 inch rubber. My question is I want a reliable economical daily driver with around 300 hp and 500-600 tq and I know the transmission can handle has a cooler and gauge so I can watch it. What are your thots on this?

I should add that I will be doing virtually no towing with it

300 hp is easy on these trucks. Here is a dyno sheet on my '91.5 D-250. This is with a stock fuel pin, stock governor spring, 30 hp injectors and stock turbo with #16 turbine housing. Last summer, I installed 50 hp injectors, stock HX35 turbo, tuned the AFC and now I am at a strong 30 psi boost, so probably 300 hp.

Ok that looks good. Not too sure I wanna do injectors right away so maybe 16 inch housing and fuel pin and tune would get me close?

Mine was a little shy on power before the injectors but I think a fuel pin will do about the same thing.

This is a dyno sheet without the 30 hp injectors. They really helped out the torque.

Ok ya looks like a lot better torque curve with injectors. Well I’ll probly do all the cheap stuff and see how she goes and then do injectors if I want more. Thanks for your input!

Which 50 hp injectors did you get?

 

[NIsaacs]

These, with new Bosch bodies.
