Every engine is different. Some people can push 20psi on the stock ignition system. Some guys start having problems at 10psi. There are a couple aftermarket pnp coilpack setups you can buy.
A highly successful and very simple setup is a set of Toyota coil-on-plug ignition coils and a DIY wiring harness that eliminates plug-wires altogether. There is a method for incorporating this with the stock ECU and with an aftermarket ECU.
For an aftermarket coil-pack, most guys will use LS-series truck coils on a custom bracket, similar to this FM setup:
Bottom line is that there will be zero advantage to a stock engine, and you stand a very good chance of not needing it in your boosted engine until approaching decent (250whp) power levels... but as I said, ymmv.
In other words, unless you have a serious hard-on for the "look" this provides you, there is no reason to do it anytime soon, and possibly not ever.
If you're looking to make some mods to your engine PRIOR to boost, I'd look at getting a radiator cap shaped like ***** head.
