Garrett G25-550 Turbocharger for Mazda MX-5

The Garrett G25-550 offers a bolt-on upgrade to the latest Garrett technology for GT25 and GT28 turbochargers using a T2 inlet and 5 bolt outlet on the turbine housing.

The new forged and machined compressor wheel is latest generation Garrett technology with up to 15% more flow than the GTX series, Gen II series on 60mm wheels and even 30% more flow on 67mm compressor wheels. Combined with a high flow compressor housing and optional connection for the speed sensor, this is the ultimate upgrade for T2 type turbochargers with 5 bolt Garret turbine housings.

The turbine wheel is made of Mar-M (up to 1050? C resistant) with 15 to 20% more flow, meaning that even with a smaller A/R housing, back-pressure is reduced without sacrificing response and lag. The stainless steel turbine housing is heat-resistant up to 1050? C, dramatically improving longevity.

The CHRA features a V-band to the turbine housing to make adjusting the turbo for each application as simple as possible. Double ceramic ball bearings offer dramatically reduced friction, increasing responsiveness through reducing lag.

Warranty information

Warranties cover defects in materials and workmanship only. Warranty is for replacement of a similar product, repair of the original product or refund of the purchase value only and excludes all labour and incurred charges including towing, fitting, inconvenience, and purchases of other manufacturer's products. The warranty is good for the period stated in the additional info tab from the date of purchase. Mileage warranties are for road use only and proof of mileage is required. Products must be installed by an independent experienced professional mechanic and the suspected defect must be present at the outset. The warranty does not cover damage caused by incorrect installation, failure to comply with the maintenance requirements of the vehicle, processing or otherwise changing the product, ordinary wear and tear, or any other external influences. Warranties are invalid if the product is used for racing, rallying, drifting, track days or any other form of motorsport or competition. Please refer to the manufacturer's own warranty documentation for more information.

Making a warranty claim

Proof of purchase receipt showing the date of purchase, proof of mileage at installation, proof of current mileage and invoice of the work undertaken by an independent experienced professional mechanic must be supplied along with the returned products for a warranty claim to be considered. If your vehicle needs to be used whilst your warranty claim is considered replacement parts from the same manufacturer should be purchased through BOFI Racing. In the event of a successful warranty claim, we will refund the card that was originally used to purchase the replacement parts, in full or in part depending on the nature of the claim. BOFI Racing reserves the right to make full or partial compensation at its sole discretion depending on the condition and mileage use of the returned suspect parts. For example, if you have used the part for several thousand miles before a defect is noticed, only partial compensation may be offered.
