A little more progress made on the Ultima. Jez has made and tacked up the manifolds. And the new big brake setup he designed all fits perfectly - custom bells and brackets with AP calipers and BTCC floating disks.

We've nearly finished fabricating a custom manifold and down pipe for Grahams Ginetta. Its running a Borg Warner EFR7163 with T4 divided twin scroll exhaust housing.

The car is going used for hill climbs and sprints - previously it had a variable vane turbo. It was very responsive but limited power. The class rules have changed recently which means more power is required to remain competitive.

The new turbo is a much more modern design which will hopefully give a load more power and still be low lag. The manifold is designed with cyls 1+4 and 2+3 into each side of the T4 divided twinscoll collector which will also help minimise lag.

The car runs a Syvecs ECU and we'll be taking advantage of its motorsport traction and launch control once the wheel speed sensors have been installed.

We love a clean S15!
