I got the parts list down

Air Dog
P-Pump
Port and Polish Head
Exhaust Manifold
HE351 Turbo
Cooler Tubz
Bigger Intercooler
Aluminium Radiator with electric fans

Should be a pretty nice set up and I'll do Injectors later, but I'll start ordering parts pretty soon and post up a thread of what I'm doing as I'm doing it, but first I'm going to go get my truck Dyno'd like it is and get it Dyno'd as I add things and let yall know the numbers.

the 24 valve head was done for emiisions and moved the injectors to the center of the cylinder instead off to the side at an angle which provide better fuel antomization and better wear for the cylinder. According to Cummins/ Mopar

Do a couple upgrades. I have a 91 cummins in my 89 suburban, 60m h1c upgrade 3 piece exhaust manifold fuel pin i had 16 exhaust housing but went back to the 18 because it was building to much boost and power! (40+) I had m&h make me a dual ram intake manifold. the fuel screw is in a bit and the afc down almost all the way and it has no problem at all keeping up with a 04 with a programmer! keep in mind this is a 91 no intercooler and i put water inj. and it makes all the towing power you will ever need.the most the exhaust will get upto is 1250 on a long long grades pulling a 1200 lb trailer!! Hey no computer or emissions!! screw the 24 valve!! I must add i am fairly new to cummins thing but i have learned tuning is everything! I dont make a bunch of smoke either.
