Here is the first rough draft of the cummins manifold

Nice buddy, you guys putting together one that you can put in a external wastegate? What turbine flange is gonna be used? If its a T-04 and has an external flange, I need one.

 

+1 T4 and external wg is where it is at.

 

lol I will pass the comments on to steed

 

I already sent a email to the shop. I might get two made up. They will fix my external wastegate issue/mess. I want both a T-03 and T-04 flange. I asked if they could get it done within a few weeks. Time to see how good my head gasket is.

 

cool i would rather stay outa the loop . that way i cant screw anything up

 

I just sent a email. I don't know if they can build a manifold that quickly. I want to get my twins built up, I'm tired of just running around town with only one turbo.

 

Looks pretty good.. Teaming up the running mates for the engine should produce some good flow.

 

I was told that I had to wait to see how the manifold looks?

I haven't figured out if I want the wastegate on top the manifold or under the manifold? They are gonna coat it with a ceramic coating. Might have to get them to add some braces for the twins

 

wow like too.


when you say 2nd gen..........can I use it on my 12v?


I'll would use one with a T4 and Ext wastegate port. on my engine.

 

should be able to get it to fit can,t remember but aren't the exhaust ports round from 1998 to 2002 just depends on the head i would guess.
I am going to try get my buddy's truck so steed can do some measuring he needs to see about clearance needs to get the lengths right of the runners

 

Hmmmm you're right about that. but gets me to thinking maybe i need to put a 24v head on mine........ or I wonder if'n I can get a CR head on there to work out.




gawd the possibilities.

 

CR head would be difficult, unless you go with a cutoff intake. The VP head has a big cast relief (that kills flow) to allow a p-pump to fit. A CR doesn't have that.

 

I forget about the pump sticking that far up and causing clearance issues with the head. You could put in a CR injection pump and get rid of that mechanical pump. They do sell aftermarket wiring harness and ecm's for the CR, so its not that ugly. 24v heads are cheaper anyways.
