M3/M4 (S55)
M3 and M4 S55: 425hp standard, 550bhp+ on stock internals.
The F80 M3 and F82 M4 share the S55B30, a 3.0 inline-six built specifically for these two cars. Standard output is 425hp, it is a very tuneable unit, and now that the engine is shared with the M2 Competition, tuning it has never been better.
From BM3 software to Vargas and Pure turbos
With the right upgrades these S55-powered cars become extremely potent rivals to the likes of supercars, with over 550bhp possible on the stock engine. So whether you want to add some power with BM3 software, or create a road-going missile with our Vargas or Pure turbo upgrades, Pumaspeed is the place to shop for S55 tuning.
We carry a wide range for these models, from M3/M4 Ferodo DS2500 pads, EBC RPX, RP1, Yellowstuff and Bluestuff, Milltek and Scorpion exhausts, through to panel filters. Looking for something not listed on the website? Give us a call.
