Following on the successful development of our cast manifold and bespoke built hybrid garrett turbo unit to produce a conversion around 330-340bhp for Z20LEH engines to replace the KKK K04 standard turbo unit, further development along with our high flow inlet manifld has given us a conversion producing 373bhp and 339 lb ft torque.

New from Courtenay Sport, a high flow Z16LEH exhaust manifold.

This cast manifold is manufactured in the same way as an Original Equipment (OE) manifold would be fabricated.

The result is a turbocharger assembly for the 1.6 Turbo engine that is capable of flowing more air, thus producing more boost and therefore more power and torque.

In fact our Z16LEH manifold has a 20% larger exhaust housing than the Z20LEH manifold and the wastegate aperture is also 20% bigger, so the Z16LEH manifold will offer much greater flow than the equivalent Z20LEH turbo manifold.

It has been designed for the Vauxhall/Opel 1.6 Turbo Z16LEx/A16LEx engines - Z16LET, Z16LEL, Z16LER, A16LET as fitted to Corsa D VXR/OPC and SRi Turbo, Astra H Turbo, Meriva VXR/OPC and Insignia 1.6 Turbo to allow the fitment of the core turbo charger from the Astra VXR Z20LEH engine.

It fits directly to the head as an OE 1.6 manifold will and the front pipe location is in the same location as the original - no exhaust adapter piece is required, so a standard pre-cat or a pre-cat replacement pipe will bolt straight on with no modification whatsoever. So this really is direct fit. Look closely at the images, and whilst this looks like a Z20LEH turbo, you will see the designation Z16LEH on the cast manifold for the 1.6 application.

We have also made provision for the addition of an EGT probe into the manifold if required.

Exclusively developed by Courtenay Sport, we are pleased to launch an uprated polyurethane front engine mount for Astra H and Zafira B 2.0 Turbo models.

This engine mount is designed to sleeve into the existing front engine mount, to strengthen it and reduce the forwards and backwards engine movement during acceleration and on over run.

Ideal for Fast Road and Track Day use.

Finished in Red, exclusively manufactured for Courtenay Sport.

Suitable for Astra H and Zafira B Z20LEx models, including VXR.
