Starting a build thread for my F80 M3 S55 stage 2 project. Current mods: - VRSF catless downpipes - VRSF 7.5" FMIC - BM3 stage 2 map - Mishimoto oil cooler Current power: ~520hp on 98 octane. Next steps are methanol injection and possibly upgraded turbos. Will update this thread as I go. Feel free to ask questions!

methanol injection on S55 is the way to go for big power on stock turbos. you can push 550-580hp with meth and good tune

Following this build thread! 520hp from an S55 is impressive. What are your 0-100 times?
