Cat diesel power!!!!

I cant help sorry,the twin turbo's have just arrived here we are way behind you guys.
I will be sticking to the older 6NZ-7CZs but there some guys on here that will be-able to help.

 

PDI is good for a stock engine.............B model manifold is better

 

Pitts has ported and coated factory manifolds, has anybody used one of these? if so how did it go? I have internally smoothed one and its now at the ceramic coaters geting coated (including the turbo turbine housing) it will be interesting to see how it goes when I fit it to the truck.

 

Keep us informed,I would be keen to see how it works out.

 

I know about the B model manifold, I just don't want to lose my jaking power

 

No man wants to loose his jaking power!..........sorry just had to say that

 

The PDI manifold is worth about 4% more flow than the stock manifold ported and ceramic coated, also they're made from a better grade of steel to resist cracking. With the amount of fuel you will be putting into the motor.........the B model is the only way to go. It will lower exhaust temperature a considerable amount.

 

I hope you didn't send it to Jet-Hot to be coated. They will bead blast the slip joints to the point that they won't seal properly afterwards.

 

To an independant guy in Brisbane, not sure who because the customer is organising it. I would have like to get them done in sliver but the coater told my customer the silver will melt so its getting done in black. should still look good though.

 

Tell whoever is doing it, NOT to clean the slip joints. Any material removed from this surface area, will result in the manifold leaking there. On reassembly CAT has a special exhaust sealer to use on the joints to keep them from leaking, but it will not seal them if too much material is gone.
