I.S.X. OR CAT ?
 

ANYONE?

isx

between those two chooses CAT

What year?
It's always a CAT for me, but i've been advised, by CAT dealer folks, not to buy 2007 CAT, and wait at least a year, too many complications... :roll:

Cat
What's up with the 2007?

My dispatcher decided to start driving again, so he is taking an o7 pete with a new engine... we do not know what engines are coming... some I.S.X. SOME CAT. I'm glad to take a bridge c 15 till we sort things out...

I don't think anyone knows, anyone tell us? every one I know wants a 06 engine

There is to many emission "improvments" on it, and too many things, could go wrong...not quiet tested yet! :sad:

that always seems to happen when they raise emission standards

They're all going to be more complicated, not just CAT.

Either way, no post 2007 truck for me for many many MANY years.

Same as ALL of the '07 engines... DPFs, new technology. The new 07 CATs have a spark plug, ignition coil, and fuel injector in the exhaust system. The DPF is an oxidation catalyst as well as a particulate trap. An electronic exhaust system with inlet and outlet pressure and temperature sensors to trigger catalyst regeneration.

Oh, and a closed crankcase, too... no more draft tubes.
