Question on the different 6.2 intakes

[84cucv1ton]

Just replaced the injection pump in this truck. Trying to help a friend out with this. It's a stock 6.2 diesel. He has an intake off of a newer 6.2. I don't think I've seen one of these. He's asking me if we can put it on. It seems that all the bolt holes don't line up properly. Anyone know of this? Try to get this done before I head into work. I can always put the J code back on. To think of it what does the intake need to be torque to? Thanks a lot have a good Friday guys

I know you torque from the middle out in a staggered pattern. I think the intake is torque 30 pounds?

the newer one if off of a civilian truck isn't it?, cucv have j- code intakes which are emissions free(like 30 more hp)

On the diesels, is there a diff between single and dual plane? What is the actual structural difference between the civi and the military intakes that make that much diff in HP? I know the rebuild kit I bough had two sets f intake gaskets, one withe the very center "port" blocked with a small AL plate, the other open, I had assumed this had to do with EGR stuff?

I thought it was 30 TOTAL hp for the j codes !!!

The "C" engines were emission engines and had the big honking egr valve in the middle. The "J" engines were emissions exempt. The "J" intake does offer better air flow but I think 30 HP might be a bench race number. You still have the air cleaner to deal with. Add a second snorkel to the air cleaner and enjoy better air flow.

sorry your absolutely right 30hp was around the total difference

It's not it Jay code or a C code. There is no big DGR valve. Looking at pictures online I think it might be a hummer intake. Maybe it's for a 6.5. Need to get this done out of my driveway. Going to put the stock intake back on. If anyone is looking at work for the intake is 31 pounds. Guy at the auto shop said some of the bolts need sealant on them and the rest Need to be Dipped a clean motor oil to get the proper torque. I've done a few injection pumps. Never heard of that before

You don't even need an intake...run without it! Good for 100 hp extra!!!

Seriously, bolt the old one in and go.

 

[84cucv1ton]

yes i am. dont have time for this. need it done and gone

 

[2002ford]

They will run without the intake. Trust me.

 

[MarcusOReallyus]

He's asking me if we can put it on. It seems that all the bolt holes don't line up properly.

The second sentence answers his question.


Is there another question?

If the bolt holes don't line up then it sounds like that intake is likely off a turbo 6.5 from a van of HMMWV. The HMMWV/Van setup with the center mount turbo had different heads with a different bolt pattern and angle to allow the center mount turbo to fit.
