Bumpin up my 6nz

Don't do an up grade at any cat dealer. You will regret it. What you should do is not allowed to talk about on here. Other than hard parts. A manifold and turbo will be a good start. Ecm work there is only one person I use but you will have to go to other sites to access him.

 

I'm looking at doing this also manifold and bigger turbo,,,,but do I really need to do the ecm tune? I went from a 435 to 550 1850 torque.( defiantly pulls better) now going to go from twins to single.

 

Going backwards in terms of performance by taking the twins off

 

If Bruce was giving away snickers bars I wouldn't take one...

 

LMAO!

 

You can, just not out in the open.

 

I added that and gained nothing. All BS

 

I put one on and got a manifold that doesn't ever leak fumes into my cab like the old stock one did. For that alone it was well worth the money. It also improved EGT's a little. Fuel mileage? Who can really say? One would have to run the same load under the same conditions a lot to really know and even so probably marginal to nil. I think people's expectations of that are always wildly unrealistic anyways.

 

If you loose an exhaust manifold gasket like I did , I'd say get one ...

The cat one sucks and leaks.. The pdi piece ( that someone else makes) has the cummins style slip joints.
And if you put the 2 side by side you can see the difference in size.

How much you gain or not is over my pay grade.....

 

If Mr Haney still does tunes. He's the only one you want to talk to. He's the caterpillar guru
