Engine Replacement - Axiom vs. 6VE1

[VXorado]

My big question to anyone who has researched this, or who has an opinion (and who doesn't) is; what is the advantage of going to the Axiom engine?

It sounds like the Axiom had more horse power, but that was mostly due to the intake system on it. By going back to the VX intake it sounds like the engine gets back down to our stock horse power (maybe just a little more)

From my understanding, the 20 HP increase is the only advantage. The direct injection allows the Axiom engine to have a higher compression ratio over the 6VE1.

Jon, my understanding is that when we have to replace the Axiom direct injection intake with the VX's stock intake, in order to get the VX ECU to work correctly without rewireing the entire VX, we lose that 20 HP increase.

I SO want to do an Axiom engine swap, but if it really doesn't gain me anything it looks like a rebuilt 6VE1 may be the best way to go.

Keep in mind that the direct injection was only availavle for the 2004 axiom,any older axiom doesn't come with the direct injection.

The 2004 Axiom comes with a 250hp stock engine while the 2002-03 axiom comes with a 235hp

The increased in the HP for the 2002-03 axiom was its electronic throotle system,better intake plemum and better cylinder heads + few other improvemets.

The 2004 axiom comes with all the above mentioned improvements + the direct injection feature.

According to iam ironman you can swap an axiom long block engine that comes with 'X' as the 8th digit on the VIN
