There's not really any power to add... The 7M-GTE's ignition setup would require a complete electronics swap which is a bad idea as the timing maps are more conservative, you'd lose the ACIS system, and you'll need to add a fuel controller to get the fueling back to normal for a N/A.
You could look into adapting one of the points conversion kits they make for some domestics or a full aftermarket setup like the ones offered by MSD; The MSD6x series if I remember correctly.
It's all overkill though, none of this is going to next you enaough of a gain to justify the work and money... if you gain anything at all.
