Few good points Jolly Roger VX’er and others
Let’s divert from the subject of LT1 for a moment.
I am not trying to replace a faulty or marginal engine. If I decide that the project is worth executing this premium used engine and other guts will be available to my fellow VX’ers and late model Zuzu owners.
The VX’s original 6EV1 is a high tech engine with unbelievably flat output across its full rpm range courtesy of selectable length runners and cloverleaf combustion chamber. It will easily outrun supercharged Toyota TRD truck and many others.
The 35HP+ can be gained on VX by easy mods that I mentioned earlier in this thread and if one wants to rollup sleeves and start degreeing cams, add centrifugal blower/intercooler preserving benefits of existing runners, computer (PCM) tuning etc. would bring the output conservatively well over 300HP! So now we are approaching barrier of 100HP/liter ratio and that is frightening because reliability and maintenance. At this point I am not addressing rest of the power train where torque converter stall speed needs to be lowered and few internals replaced…..
I am not familiar with the Axiom power train but 30extra ponies and direct injection decal would not make it my choice, furthermore that new engine is not around long enough to proof itself. Isuzu is pulling out of passenger vehicle market in its’ present form so good luck with spares and any support on that engine!!!

Thx, VX922
