This thread will serve as the IE 2.5L I5 product library that we continuously update with our new releases. This will make it easy for you guys to find what you are looking for and we wont be making new threads for every new product on this fast growing platform. Also, if anyone has any questions, comments, or suggestions please post them in here. We offer a huge inventory for VW/Audi and other makes including internals, valve train, fueling solutions, hardware, OEM parts, billet accessories, turbos, and much more. Not everything will make it into this thread, so if you dont see what you are looking for check www.intengineering.com or e-mail sales@intengineering.com
Valve Train
IE offers a huge selection of valve train parts for your 2.5L to help your 5 cylinder motor breath and rev harder.

Integrated Engineering 2.5L 5CYL Spring/Retainer Kits
Integrated Engineering spring kits for 2.5L 5CYL engines are performance tested kits featuring aircraft grade titanium in-house CNC'd retainers to exacting tolerances and surface finish requirements. Optimized to match your vehicle specifications and provide proper valve control under high revving applications, the springs are wound in the USA from the purest spring steel available in the world and nan-peened for incredible fatigue resistance. These are engineered for the wildest setups, and tested to perform with long life and reliability.
Sold as a complete set of high performance valve springs and titanium retainersOrder here
Ferrea Valve Spring and Retainer Kit
Heavy duty valve springs will prevent valve float at higher rpm. Titanium retainers will help keep the weight down, while providing extra strength. Valve springs and retainers are a MUST for high revving engines!
Sold as a complete set of high performance valve springs, and titanium retainers. Order here
Integrated Engineering Valve Guides
It is always a great idea to replace your valve guides when doing a cylinder head build. These valve guides are made in house on our CNC lathe, using a proprietary bronze alloy. This alloy allows for 10% faster heat transfer, as well as better wear characteristics to make for a longer life. We have designed these with an aerodynamic tip design to cut down on airflow restrictions in the port. These valve guides are made with ultra high concentricity for exact valve placement, with precisely sized outer diameters. Standard 2.5L 20V I5 Sized. Sold individually (20 required for MK5 2.5L 5 cylinder engines) Order here
Integrated Engineering 1.8T Valve Seats
Integrated Engineering valve seats are the performance option for replacing factory seats when doing your cylinder head build. In high revving performance head builds, factory seats are prone to excessive wear resulting in premature valve failures. To combat these issues our valve seats are made from a specialized alloy on our in house CNC lathe for dimensional accuracy. Using a proprietary bronze alloy results in faster heat dissipation where thermal conductivity is increased by 10% and extends valve life, seat erosion, and cylinder head component life.

Bottom End
IE offers everything you need to build a strong short block. Everything for all motor or all out forced induction builds, we have what you need with much more coming!
Integrated Engineering H-Beam Connecting Rods
Integrated Engineering is proud to manufacture the highest quality connecting rods available for European applications, at a reasonable price. This is accomplished through careful design, manufacturing, and quality control processes. With hundreds and hundreds of sets of VW and Audi connecting rods in stock, we are your specialist supplier with the inventory and knowledge to make your project a success. Sold standard with ARP2000 bolts. Order here
JE Pistons
JE pistons are a great upgrade for someone looking to build a stout, reliable engine. They have 20mm wrist pins so they will require a set of rods with 20mm pins to match. They feature JE's 2618 alloy which is stronger then most other pistons made from 4032, and are specifically engineered for extreme applications. Custom pistons and coatings available to order.
JE 83MM Bore 8.5:1 CR 92.8mm stroke Orde here
JE 83MM Bore 11:1 CR 92.8mm stroke Order here
SPA T3 Turbo Manifold
This is a high quality SPA Turbo cast iron turbo manifold, these are cast in their own foundry, and thoroughly tested in real world driving conditions. It features a T3 flange, so it can be used with a T3 or T3/T4 turbo. It also has a 2-bolt wastegate flange, for use with 38MM wastegates. Order here
