This kit is made for you if you are really serious about increasing performance. Our ULTIMATE kit contains everything you need to make you and your engine happy: power up to 1000 hp with your 5 Evo cylinder engine!

Perfectly tuned: 2.5L TFSI ULTIMATE Kit for up to 1000 hp power for your DAZA and DNW

Whenever you think you can't go any further, think of this kit. Because here we have once again outdone ourselves. The ULTIMATE Kit is not called that for nothing! It gives you everything you need for the best performance from your 5 cylinder: a perfectly matched combination of forged pistons, connecting rods, connecting rod bolts, connecting rod bearings, head gasket and stud bolt.

Visually alone, this set can do it all: Our BAR-TEK® ® H-shaft steel connecting rods are titanium-rivetted, giving them a golden chandelier. The matching high-performance Pistons from JE Pistons are available as Ultra Series. All other parts are also of the highest quality: ARP connecting rod bolts, connecting rod bearings from ACL, MLS head gasket from Cometic and ARP stud bolt for the cylinder head.

That's really all you need Not only do these components harmonize perfectly with each other, but you too clay money as a set compared to buying them individually!

Extreme kit for extreme performance

Of course, our kit is not only an eye-catcher, but is also designed for extreme performance. Your 2.5L TFSI will be able to deliver up to 1000 hp without any worries! This is because we pack only the best components into our Ultimate Kit and they are optimally matched to each other .

The JE Pistons piston in this kit are specially coated for extreme performance and come with the High Boost piston pins. At the same time, they are still quite light. This combination is of course perfect for Motorsports . The piston comes with everything you need for installation: pins, rings and clips.

Our specially titanium-nitrided steel connecting rods are also extremely light and at the same time very stable . Thanks to their surface, they can easily withstand high pressure loads. They are milled from solid material and have an additional hole for better piston pin lubrication (rifle drilled). They also come with everything you need for assembly: the matching ARP2000 expansion bolts and assembly paste.

These two parts are the stars of the kit and are rounded off by high-performance bolts, racing bearings and more. As I said, more is simply not possible !
