MazdaSpeed3 DISI Turbo
I have a cold air intake, blow off valve, and basic Cobb Partial Stage 1-af tune.
Screwed my first engine and had it replaced with a DISI from a CX7 with 40k miles on it.
I had all my original parts moved to it, including my bigger turbo.
Replaced the spark plugs. Cleaned the EGR...
