So how do I know what IP I have. THe truck is a 90 the motor a 93. I was told it has the 93 injectors and pump. With the 90 non-intercooled intake/turbo etc.. I would also like to know what tranny I have. It is a 3 spd auto. I was told 727, but I find that hard to believe. I just got the truck and it would be my 4th or 5th diesel. I love the sound of the 6BT though. I got truck for 700 bucks thought I would sale it and make some money. I might just have to keep it though. Wife will probably kill me. Come to think of it my daughters might to. Long story.

 

It appears you've been mis-informed... sort of. The IP's for all 1st gen's are the same; Bosch VE. The only difference is whether it has a throttle position sensor, (TPS) to it or not. The TPS came on the 91.5, (I think?!) through '93 trucks with the A518 auto tranny. It's essentially a 727 with an overdrive unit attached. You do have a 727 in yours, being a 3 speed.
The injectors are likely the '93 ones, as they had a smaller body than the '90 and aren't a direct fit. They flow a shade less fuel, and are one of the first things folks tend to upgrade.

...Seems kinda weird to have a '93 block and a '90, (non-IC) turbo/intake etc.

 

TIming gears went kaput in 90. Instead of fixing gears he put long block out of junkyard truck in. Donor truck only had 103k on it when he swapped. I don't know why he did not get the intercooler and stuff with that motor. As far as I know it is the 90 turbo. Is the turbo different on the 93 or just the configuration?

 

Actually, I can't remember. I know mine has an 18cm2 turbine housing. They, (Cummins) also made some of the 1st gen's with a 21cm2 turbine housing, commonly referred to as the Lagmeister/Lagmaster. I can't recall which years they came on, but if you look on your housing it'll be stamped on it, usually on the underside... of course. Mirrors on sticks are a great invention!
