you will need a pump, timing cover, timing gear (nut and washer also). you will need new fuel and return lines (the old banjos are too small for the new lines) you will need the banjo fitting for the pump inlet (or any alternative way to get fuel to the pump). you will also need an overflow valve, throttle linkage, a new throttle cable, injector lines, injector or at least new bodies. support bar for the p pump. and you will need an oil feed line as well to the p pump;. i think the hardest thing to find for me was the T in the side of the block that sends oil to both the vacuum pump and the injector pump, since the 1st gens only have an oil line to the vacuum pump. i think thats pretty much it, if im forgetting anything let me know

Just wanted to bump this thread up incase anyone else has any additional info.

I'm doing this exact thing but I have a complete '96 engine with a holy block so I want to use the '93 engine but swap everything from the '96 onto it. Everything i've read says this is just a bolt on procedure, but just wanted to make sure that all the parts from the newer engine will bolt to the '93 block.

Thanks for the info tltruckparts, Just want to make sure that I'm not going to have any big surprises when I rip into this:rocking:

From what I understand, which is limited, the block was exactly the same until they went to the 24V. So, you should have no worries... famous last words.

no bog surprises, tltruckparts listed everything i think, if you do have the extra money its not a bad idea to get an after market cam since your going through all the work.

Why don't you just put that 96 motor in why tear apart a good thing just my opinion I want a 24v in mine does any body know if someone has one in there rig I mean why go threw all that work to take parts off and put them on something else

Thanks for the confirmation guys:c: I just finished swapping the gear case and ppump onto my '93 block and it all fit perfectly:tu:

It is a lot of work:argh:, so it probably would be better to just grab a ppumped motor and drop it in, but I got my '93 engine for less than half the price of what a '94-'98.5 engine would cost me and it looks like new inside:jump::yeah: now I just need to find out if the '93 head will work with the '96 accessories.

Nice!! :jump: Glad you got it strapped on. Time for pics and numbers! :rocking:

It will.
It interchanges from '91.5 through early '98.

Guys, keep in mind, there's 2 different set-ups for the rear pump support, '94-'95 and '96-'98.
The early one uses a thick, cast 'T' block on the pump, the later one is stamped steel.
I don't think they will interchange.

Mark.
