BMW B58 Turbo Kit

April 16th, 2021 by

There has been a lot of excitement in the tuner community over the last few years with the buzz around the BMW B58 engine. This 3.0 litre straight 6 turbo engine comes in the BMW 140i and 240i along with the A90 Supra. So far this engine appears to have some huge potential, most famously Papadakis Racing achieved 1000bhp fairly early on for their Formula Drift Supra piloted by Fredric Aasbo (Whom we have a technical partnership with on the European side of things).

Engines like this usually mean 1 thing….. Constant emails and phone calls from you lovely people asking for our take on a turbo manifold. So with that, we give you our BMW B58 Turbo kit for the M140i/M240i

Based on our standard manifold construction processes, the B58 manifold has all the same features as our other manifolds (see here). Although we have gone with a bottom mount in this case. The reason behind this was primary tube positions to give good flow and also to reduce downpipe restrictions. the turbo being top mount would cause a downpipe with more bends and therefore more restriction (each bend caused the gas to slow down)
