has anybody made a list of what parts are transferable from the early non-intercooled trucks to the later (1993) intercooled trucks? I'm parting out a '91 but don't want to get rid of anything i can use. both are 250s/4x4s /auto.

 

I'd save pretty much everything I had room for. Short of the wiring....the trucks are pretty much all interchangeable. The stuff that isn't interchangeable is usually in demand by someone.

 

i guess i'm wondering more specifically what isn't interchangeable. a few things i know: injectors, IP (without modifications), intercooler components.......

 

81to 93 is all same body style so fender's and stuff like that swap over real easy As far as injection pump it will work but has to be changed around some .

 

Injectors are interchangeable with an adapter

 

save the wiring, I had saved the wiring on a rolled 93 and was very helpful finding a electrical problem on a 91. gauges did not work and blew fuse, it was easy to follow the blue wire with white tracer along the harness to a splice to 6 other b/w wires in the loom totally undetectable to the eye then trace each out and start disconnecting one at a time to find it. save everything, if you have a turn signal or key problem simply hold the piece up to the steering column and connect it up and see if it fixed the problem

 

can you tell me more about that? (the injector adaptation). Thats actually what i'm working on right now.

 

With the adapters you can make the 7mm intercooled injectors fit in the non-IC 9mm trucks. A lot of diesel performance sites have them, even eBay.

 

He is parting a '91 and wants to keep parts for a '93.
Getting those 9MM injectors in a 7 MM hole will be tough.

 

i thought maybe he had some sort of magic process that i was otherwise unaware of up to this point!

 

I am all ears too.

 

Haha, yeah sorry probably should have paid more attention. I don't know of a way to make 9mm's fit in a 91.5+ truck.......

Yet

 

There is 1 way, a drill, a tap, a very good magnet and the world's largest juevos...Mark

 

Hahaha. I thought about mentioning that, you would need some serious confidence for that job.

 

The other way is to have the injector tip machined down to 7mm, I've seen it somewhere....just can't remember
