The Fifth Generation of Toyota Supra officially went on sale in May 2019. The car is a collaboration between BMW and Toyota and as such is equipped with the BMW B58 inline six that can also be found in the G29 BMW Z4. In its standard form the B58 provides the Supra with 250kW which, while healthy, leaves plenty of room for improvement. The Kelford range of catalogue camshafts are currently in production and set to become available in 2020. Our custom spring and Titanium retainer kit is already available.

BMW have released these engines in several revisions. To simplify things the Kelford team have named these revisions Gen 1, Gen 1.5 & Gen 2
If you are unsure of the generation of your engine please contact the sales team & they will make sure you get the correct camshafts
