well, i have different coils...i'm running the updated coils for the 1.8L...they're better coils than what's on the stock p5...you can get them at a dealership for around $35...and if you can find someone with a MP3 willing to sell their ecu, get it.
Newsflash.... modern stock ignition systems are awesome. You won't need to upgrade your ignition system til you're running huge amounts of compression.
