MuchBoost MDI 525 TD5 Upgraded Turbochargers with Enlarged Billet Compressor Wheels and Enlarged Turbine Wheels. They are based on genuine Garrett turbochargers, which means that the installation is 100% P&P. The turbochargers are meant to work with Land-Rover Defender, Discovery II with the 2.5TDI TD5 122-139HP engine.

The turbos deliver up to 204% of stock power (128HP extra) which means it could be perfect for a faster daily driver, to gain some additional power.

We have developed 2 modification options that allow you to reach anywhere from 220HP to 250HP.

MuchBoost 2.5TDI TD5 220

Upgraded turbochargers with an estimated ~220HP at the crank. List of modifications:

• Precisely machined seal plates and compressor housing,
• More efficient and larger Billet Compressor Wheel 11+0 blades,
• Upgraded journal bearing system that allows the turbo to hold more boost,
• Clipped and Lightened Turbine Wheel,
• Genuine Garrett compressor housing,
• Genuine Garrett exhaust manifold,
• Genuine Garrett bearing housing,
• Original Garrett actuator,
• The compressor and turbine wheels are balanced separately, and then the whole core is high-speed balanced using VSR balancing machines at speeds similar to the level seen in the vehicle.

MuchBoost 2.5TDI TD5 250

Upgraded turbochargers with an estimated potential of ~250HP at the crank. Modifications compared to the 220 option are the same except:

• Enlarged Compressor Billet Wheel,
• Larger Turbine Wheel,
• Precisely machined exhaust housing.

Other significant modifications

In order to reach that level of power, you need to adjust your fuel, exhaust, and cooling systems as well.

One of our clients managed to produce 223HP and 468Nm of torque. Dyno graph below:

A Ball Bearing conversion is available. Brand new genuine Garrett ceramic ball bearings are used in the upgrade. The main advantage is ~20% quicker spool in comparison to journal bearings.

A set of gaskets is included with every option you choose!
