The mighty little B48 392WHP

2017 BMW 125i B48 2.0T making a good punch.

We have been testing a large bore turbo for this platform. Direct factory look and fitment with all the right goodies inside 😉

This week we turned it up and Man it made good power. This is more then a stage 2 Gen 1 B58 makes.

✅ Upgraded turbo
✅ Downpipe
✅ Intake
✅ Upgraded heat exchanger
✅ Upgraded sparkplugs
✅ Upgraded HPFP
✅ E45 blend
✅ Custom ECU tune
✅ XHP TCU tune

This is almost 460HP at the motor😲

We are on the limits of fuel with this setup but hey we might even go further with a few more added parts😉

Abarth 595 comp gets a good bump👌

We do love our S260 turbo upgrades and so did this little Abarth.

Peter was after some more punch and some longer legs but still wanting his Abarth super reliable and a easy daily driver.

The S260 upgraded turbo is the perfect combination. Direct bolt on to factory manifold and even factory downpipe and intake. The kit comes with all silicon hoses, water and oil fittings making it a direct bolt on kit.

Peter opted for a custom catted downpipe and air intake and now producing a easy 70hp gain on pretty much factory boost level.

We have produced up to a 100hp gain with this setup and a few added mods.
