how much on stock 4.0 sohc internals?

I was wanting to run the most i oculd on pmp gas.
but what other mods would it take to run more then the "normal" 5-6 psi kit?

Lets see, I would recommend no more than 13psi. with stock internals and good tuning. If you run boost then the support hardware is necessary. Upgraded fuel pump, injectors, MAF meter & of course-tuning. Questions feel free to contact me.-j

is anyone on this site selling a kit of this nature?

and would the stock driveline hold up to and extra 100 hp?
