My idea of a symphony? Six pistons playing a tune my right foot tells it.

Anyone know what is needed to take a normal 4.0 I6 and convert it to a 4.0 HO?

I'm sure somebody with more knowledge will chime in but here's what I can remember off the top of my head:
- complete wiring harness and ECU
- head
- intake/exhaust manifolds
- fuel rail, injectors, TB, etc
- flywheel/flexplate
- I believe the cams are also different, but I don't think you would have to change it
- probably some other things I've forgotten
I do believe it is also possible to retain the original electronics with a little custom modification to the throttle body, but I'm not positive.

Just change to a HO head, that's where most all the power difference is. Really not worth changing everything else.
