        New, uprated, lightweight Race Billet Compressor Wheel. Our Upgrade Billet Compressor Wheels are designed for performance use and enhance the airflow of the unit thanks to Increased Inducer Efficiency and Extended Exducer technology. Manufacturing this wheel from solid billet alloy via a computer controlled 5 axes CNC milling machine allows us to machine blades to the tightest of tolerances, reducing weight over the original wheel  and reducing spool times by up to 500rpm.

    12 Months Parts & Labour Warranty

    FITMENT: Direct fit to original housings, no machining required, no modifications.

    PERFORMANCE INCREASE:Power = 10%  Strength approx 20%

    OTHER REQUIRED MODIFICATIONS: Fuelling check is required with adjustment where required. Unit will replace original standard turbocharger CHRA, although to maximise performance, upgraded breathing modifications are recommended (filter, zhaust, cooler etc). 

    RATED POWER: 225HP*

    *rated power is based on 100% reliability. Although more power could be found by increase boost pressure, doing so will begin to affect reliability. 

    Following fitment and remapping of an Enhanced Turbo, if your Dyno run power figure tops our leaderboard, then we will refund £50 from your order! Simply send us a copy of your Dyno run, a spec of the vehicle and a picture, and we will show the world your pride and joy.

    Turbo Rebuild are the professionals in the enhancement of production Turbochargers.

    Since the millennium, our experience in the repair of failed turbochargers, combined with the continuous development of power upgrades, remaps and easy access to rolling road Dynos, we have found many turbochargers simply cannot handle the performance that the engine requires.

    So what is an enhanced turbocharger? Do you mean a hybrid Turbocharger?

    Well, it’s a yes and no. An enhanced turbo is a unit that has been improved to provide maximum performance without compromising reliability. This in itself is indeed a hybrid turbocharger by definition, in that the turbocharger has been modified and upgraded. However, an enhanced turbo isn’t a full on fire-breathing hybrid turbocharger with enlarged wheels etc. If you’re chasing figures, then an enhanced turbo is not for you.

    An enhanced turbo maximises the potential of the OE Turbocharger and is ideally suited to applications where the vehicle has been tuned or remapped.

    So what do you actually offer?

    Turbo Rebuild can offer complete, brand new, enhanced turbochargers and also many enhanced Turbo CHRA, typically these come in 2 forms: Remap and Race

    REMAP

    Our Remap units are turbochargers that are enhanced to provide 100% reliability in applications where the vehicle has been remapped. These units require no remapping after fitting; they are 100% plug and play. Each Remap Enhanced Turbo is meticulously built by hand by one of our own time-served, professional turbocharger technicians. Specifications of the Remap range vary on each application, with typical upgrades including upgrade 360 race bearings, total closure oil seal piston rings and performance high-speed precision balancing.

    RACE

    Our Race units are turbochargers that are further enhanced to maximise the original turbocharger’s possible performance whilst ensuring 100% reliability. Our Race units will, in most cases, require a fuelling check with some minor adjustments possible to ensure both reliability and to maximise the performance. Most of our Race units flow over 10% more power than the original, faster spool and are more reliable than the original.

    We can also offer bespoke products depending on customer requirements.

    The development in our enhanced units has been extensive and time consuming, but we are confident that we offer the No. 1 solution for remapped vehicles to fix what is the weak point...

    Are these turbochargers good quality?

    This is the most asked question we get! All CHRA are built in-house by our own professional turbo technicians using OE quality aftermarket parts where OE is not available. Our component suppliers follow strict requirements for our products which include heat treating, complete finishing of all casting components, and drag reduction polishing of bearing faced components to reduce friction. All units are balanced in up to 3 stages to ensure the best possible balance, operation and reliability. Every single unit is quality controlled at multiple points in the production stage; we feel you cannot buy a better product, which is why we offer the following warranty.

    12 months unlimited mileage parts and labour warranty.

    Free extended 2 year parts warranty!*

    *Extended parts warranty covers any turbocharger internal component which has failed due to incorrect assembly or faulty component. Warranty does not cover damage caused by oil contamination, starvation, foreign object damage, using unit outside operating limits or damage caused due to damaged or faulty engine components.

     Free extended parts warranty to be undertaken solely by Turbo Rebuild.

    Unit must not be disassembled in any way before returned to Turbo Rebuild.

    A one-off labour charge of £100 plus VAT is applicable to all repairs.
