Turbocharger K04 Z16LEx A16LEx B16LEx 1.6 Turbo
K04 (Z20LEH) Turbocharger assembly with manifold for 1.6 Turbo Z16LEx/A16LEx/B16LEx
Corsa D K04 1.6 Turbo / Astra H K04 1.6 Turbo / Meriva K04 1.6 Turbo
This turbocharger assembly consists of a K04 Z20LEH turbocharger fitted into our cast manifold suitable for 1.6 Turbo engine.
The turbocharger assembly is the same unit as fitted to the Z20LEH Astra H VXR/OPC engine, but mated to our own cast manifold featuring a 20% increase in flow.
The 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,A16LETas 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.
Available with Z20LEH K04 turbo unit which can be supplied with or without an upgraded turbo bearing pack and exhaust wheel cut back.
K04 Assembly is capable of producing around 280 - 290 bhp
K06 variant also available.
