1990 p pump conversion upgrade questions
 

Ok, im now trying to figure out what combo to set up. I have a 1990 rotary, im doing the p pump conversion, i have the injectors out of a 1997 5.9, i want to upgrade with different nozzles, cam, turbo. Just not sure what to go with, way to many options!! The truck is a 1985 CC chevy, 4wd. It will be my daily driver, occasionally pull a toyhauler, and a lot of wood in the winter time. I would like to get to the 400-450 hp. I will do pump upgrades also. Just not sure what cam, turbo, and injector nozzles to run. I see some people are saying the spray pattern is different in the early model injectors? Just throwing this out there, but would a turbo from a 1999 24 valve get me where i want to be? I will also be installing guages!! Thanks for any help guys!!

Still havnt heard back on those injectors for ya. For 450hp i would do a 60mm turbo which there are a few options there like a 35/40 or a s300 and no bigger then a 181/210 cam and head studs. I would just tune the pump up with a modified 100 type plate 3200-4000 gsk some 191 dv's rack the barrels and put a rack plug in it while its off since you have a 180 pump then i would bench the pump after the mods to balance everything out and pin it for 16* of timing. Then a set of 90-125hp injectors. Add an airdog and a new OFV to make sure it gets plenty of fuel.

Be a fun daily driver
