Enhance Performance Astra J VXR Garrett G25 Manifold Kit

The EP Astra J VXR Garrett G25 Turbo Kit has been designed and fabricated with no budget in mind, we simply wanted to produce the highest quality, most reliable kit available. We took an all original approach, firstly in order to try to retain as many OE components as possible, with the least amount of modifications required. We decided to retain the OE cast manifold and use a compact V-Band adapter, keeping the manifold volume small will help build boost much quicker, resulting in being able to use a larger size turbo with less lag!

This kit is suitable for anywhere between 450hp and 550hp with a turbo of your choice, depending on your requirements, offering unrivalled value for money with the genuine reliability of a large frame turbo compared to a re-engineered hybrid turbo. It provides increased spool time over hybrid turbos, but with the potential for way more peak power.

Utilising the new Garrett G25 turbo range, we are able to offer the latest turbo technology, big peak power figures, yet keep it compact enough too fit down the back of the Astra J VXR’s engine back without any heat issues, even retaining all OE heat shields!

This kit has been constructed to the highest standards, a billet flange is machined flat to create a perfect seal against the OE manifold. The adapter manifold is produced with 3mm wall stainless steel, fully TIG welded and back purged for longevity and reliability.

The downpipe is also constructed fully from T304 1.5mm wall stainless steel, fully TIG welded and back purged for reliability and longevity. Fully compatible with EP cat-back exhaust systems, along with OE cat-back, although a full 3″ bore system would definitely be recommended. We offer both 3″ and 3.5″ downpipes options, 3.5″ recommended for peak power gains with the G25-660 turbo option.

The intake is built from lightweight 6061 T6 aluminium, 90mm in diameter, powder coated satin black for an OEM appearance. It also features a built in MAF boss for ease of installation, supplied with Vibrant performance filter. A bespoke JS Performance silicone intake hose has been created to suit the larger bore turbo and MAF pipe, resulting in no intake restrictions.

A lifetime repair or replace warranty is also included as with all of our stainless steel products.

Oil and water lines are included as direct fit items, with no need to source any clips yourself, everything that you need is included. We use braided coolant lines with AN fittings that will last a lifetime, offering OEM levels of reliability. This truly is a fit and forget kit with everything required to installed included in the box.

Optional ceramic coating to the manifold adapter & turbine housing are recommended for cars with heavy track use, where temperatures will remain higher for longer.

Direct for Airtec intercoolers.
