So I am converting my 91 5.9 to a p-pump. Already have all the parts except the injectors and a new turbo.
I am planning on installing 4000k governor springs in it. As well as 191dv's and a fuel plate. I have been looking at a Industrial Injection Silver Bullet 62/80 turbo for it.
My question now is what size injectors would be best for it? Also would the 94-97 injectors fit into my engine or do they need to be 89-93 injectors?

Any help would be great.

I couldn't seem to find solid info on this while search all day.

 

you need 9mm injecors for the first gen. if the engine came factory without an intercoller you need 155* spray angle injectors it may be all 1st gens had 155*?

 

Thank you for that info. It was sold to me saying it was an intercooled engine. Is there any way to find that out for sure?
Also if I get the first gen 9mm injectors, what would I have to do to go about getting injector lines to bolt onto the p-pump?

One other question I just thought of. Is a camshaft change necessary to install the p-pump? I know I will have to pull the one that is in it to install the timing case.

 

the tag on the engine and run the #'s at dodge is the best i can tell ya.
as for the injector lines IDK? ide call an injector place DDP, SDX ect and tell them what you got and see if stock 2nd gen lines will bolt right up.

the camshafts on the 1st and 2nd gens is kinda sad. not much of anything good to say there. they last but there is much room for improvement performance wise. but again i dont know what your gears in the 1st gen are going to look like compared to that of a 2nd gen. i would assume it is all the same... but im not looking at it and thats a guess. if its apart and you have the money upgrade the cam while your in there

 

I sent DDP an email about the lines and injectors. Hopefully they can help me out some.

If I do go with changing cams I will most likely go with the 181 cam from Hamilton cams. I have been to their shop a few times and are all real good guys so I will go with them. At $600 for the cam it sounds reasonable. Since I am taking to old one out might as well go all the way and install a better one.

Now I just need to make a list of parts to buy.

 

good luck man. keep us informed

 

Will do. You have been a great help. If anyone else has any tips or info to throw at me I am more than willing to soak it up.

 

1st gen injectors will not bolt up to 2nd gen lines. different thread sizes.

 

I have long figured that out.

Although I did look up the CPL and found out that my engine is a 1991 Intercooled engine. So the injectors from a 2nd gen will fit just fine.

I am most likely going to put a cam into it at the same time. Might as well since I am in there.

 

Any progress?
