Engine/Transmission (1994 - 1998) Diff between 1st and 2nd Gen 12v's

[WMowat]

What are the major diff's between the 1st and 2nd gen 12v's, are the parts swappable, is the cyl head the same ? flow less or more and what about the blocks weaker , stronger ? Thanks

There were several idderations through the years, most all of which were improovements. Primarily what separates the first and second generation trucks is the injection pumps. There are MANY other difrences as well but this is the biggest.

Can one put a P7100 on a 1st gen engine? I assume it can be done, but is it worth it?

 

[HBrunton]

it can be done but you will have to come up with a timing gear housing. they are different for the rotary pump and the inline p7100.

Early 1st gen motors have a different injector nut size if I remember right.

So, when you say different timing gear housing, would the 2nd gen housing work or does one have to completely customize one and/or even have one custom cast for the application?

JGheen, the second gen 12 valve gear housing will work on the rotary pump block to install the P pump. After this, you will have to have new injector lines made to mate the P pump with the older style injectors. If the block you are using was not intercooled, the cams will also be different. If you do not intercool the new "creation" I suspect the fueling level will easily be great enough to create EGT problems fast. This would nullify any power benefits you gained from going P pump in the first place.

Thanks for the info. Ronco,



I was just curious cuz my cousin has a '93 and he was wondering what it would take to run a P7100 on his engine. I guess if he has the time and money, he might do it, but we'll see after I inform him of what needs to be done.

What I'm really looking for is this, I have a 5. 9 Industrial motor, its a CPL 0599, 169hp@2100 rpm. Its aftercooled... It has the Bosch CV pump. I think. If it makes 170 hp at 2100 rpm what will it make at 3000 with a 3000 GSK ? Is the cam the same as the newer intercooled motors ? Is the industrial block and innards better than the automotive application ? What are the diff's between the automotive and industrial heads ? Is the air to air intercooler better than the aftercooler ? I know someone here can answer all my questions. . Reason Is I'm thinking of just selling it to make a profit. Or should I keep it if its better than the automotive apps . . ????

If you look close the body also has some changes



Just kiddin'



Weren't intercoolers also introduced?

It has a VE pump and the gsk kit will not work

Is the cam the same as the newer intercooled motors ?

NO

Is the industrial block and innards better than the automotive application ? What are the diff's between the automotive and industrial heads ? Is the air to air intercooler better than the aftercooler ?

It has an air to water intercooler. That CPL 599 @177 hp is the SAME motor as a CPL 600 @ 180 hp (automotive application) other than some changes to the VE pump (all the other CPL parts are the same) That is the older style head with the 9mm injectors and I would bet good money that the head is cracked on allmost ( if not all ) of the chambers between the injector holes and the exhaust valves

I know someone here can answer all my questions. . Reason Is I'm thinking of just selling it to make a profit. Or should I keep it if its better than the automotive apps . . ????

I will give you $5. 00 for it will that make you a profit? That way I can have 2 of them!
