Have my heart set on a 4.4L GTS style build.

2008 E92 M3, just crossed 75k miles. Following the S65B44 roadmap…just stroked to 82, with proper heads, bolts and crank (rod bearings are table stakes). Ideally will have Epic provide the tune per Mueller if possible. Parts kit from VAC.

I’ve not had deep engine work done before so would love to hear where you guys have taken a car for reliable engine work or shops with good reputations within a day’s drive from Seatttle you recommend. Much appreciated on any replies :thanks:

I don’t think there’s anyone in the region up for this kind of work. Would look at Deansbimmer in Texas or Carbahn as potential options. Or Partee Racing. They are all multi day drives or better yet, shipping to and fro (you don’t want a 1000+ mile road trip at all highway speeds for break in).
