Engine Replacement - Axiom vs. 6VE1

[vt_maverick]

I thought I read in those threads that the 04 DI engine was a no go, that you had to use a 2002 or 2003 engine? If you go to the 02/03 engine you get 15 extra HP and 0 extra torque. My Axiom engine burns oil as bad or worse than my VX so what's the point? Personally I'd either go with a rebuilt VX engine or upgrade to something completely different with significant advantages, like say the Isuzu diesel for big MPG improvement or a V8 / turbo Ecotec for big HP. All depends on your budget and how loyal you are to the stock configuration.

In summary I would say "go big or go stock."

Ash, I seem to remember reading the same thing: that you have to stick to an '02-'03 engine with "X" as the eighth number in the VIN. If the Axiom's have the same possiblilty of oil buring as the VX engines, for just a couple of more horsepower and no torque gains, then the best bet seems to be going with a re-built VX engine. All new parts, usually some kind of warranty, and a definite plug and play application.

It would be great to do some kind of V8 or diesel swap, but she's my daily driver so as soon as she goes under the wrench I am out of a car until she's fixed. With that in mind, and the fact that I don't have the mechanical know-how to do it myself or the funds to pay a mechanic to figure out how to shove any other engine in there, I'll probably go the re-built route.

That'll be my new catch phrase: "GO STOCK"

Probably a good plan. I've heard Rotella 5w-40 diesel grade engine oil can prevent oil consumption. It's very high in detergent and can keep the piston rings from clogging. Might be a good idea if you end up with a rebuilt 6VE1.

I am hoping that with a rebuilt 6VE1 the oil buring problem will be taken care of. If they bore out the cylinder a bit and use new rings and pistons, I would think that that would solve the oil issue, but I guess I'll find out soon.
