There's no replacement for displacement, which is why 5150 AutoSport is so excited to finally release our BMW S58 Stroker Kit to the market. That's right boys and girls, they're here and they're ready to turn your modest 3000cc S58 into a 3404cc Bully.
These kits include the most extreme, heavy duty internals on the market, including the 5150 AutoSport 4340 Billet Steel Crankshaft, Xtreme Duty Cylinder Sleeves, CP-Carrillo Pro-Xtreme Forged Connecting Rods and Pistons that you need to turn up the power.
We've put stroker kits in some of the fastest, highest horsepower engines in the industry, from our own 'Bully' E36 to the MKV Supra, with only great results. Now, it's time to change the S58 Game.
Benefits of a stroked engine and increased displacement include greater torque at lower RPMs, improved throttle response, increased horsepower, and improved air-fuel mixture combustion.
There is a lot of work that goes into creating a kit like this and a lot of specialists working behind the scenes to make work like this possible. We would like to take a moment to thank 5150's dedicated team of engineers and engine builders for all of the hard work that they put into the creation of this kit.
A special thank you to our partners at CP-Carrillo and RK Autowerks, whose engineers worked tirelessly with ours to create a truly unique, ultra high-quality kit. An additional thank you to RK Autowerks for being the first to test this kit in their world-record G80 M3.
And as always, a huge thank you to our customers, who make our work possible.
So, who wants to be the first S58B34?
