Default how good is the stock coilpack/ignition?

the stock 2.5RS puts out about 165hp flywheel. most RS-T guys are putting down close to double that number with bolt on turbo kits with a standalone and even more with built motors. i've always wondered if the stock coilpack could keep up providing a strong spark. for upgrades, most standalones can run aftermarket external ignitors and direct fire coilpacks in wastespark mode. the only non stock coil/ignition system i've seen used on the 2.5RS is the tec2/3 systems. any thoughts on this?

There have been threads about this, and they've mentioned that the stock coilpacks are actually pretty good and do not need to be replaced when doing said upgrades.

i have read a lot of those threads. most of them were of people asking msd for ignition upgrades and msd stating the stock system was good enough as a reason for not having any sort of upgrades. i'm looking for more factual infomation.

wrx/sti also has different ignition system. they run individual coil pack/ignitors on the end of each spark plug.

the 99+RS unit is two coilpacks put together firing in wastespark with a built internal ignitor. i was under the assumption the wrx/sti fired straight direct fire. not too sure on that..

if you do a search for the big wrx power threads, look at all the guys putting down 400-500+ hp to the wheels. i've been following these threads and dont remember anyone ever using an upgraded ignition.
