  1. Renault Megane R26 F1 Team edition
    Mileage: Car 84500 miles, 2500 miles since full engine rebuild.
    MOT until: 28/08/2023
    Owned since: Aug 2018
    Price: £13995

    Unfortunately, me and my dad have decided to sell our Renault Megane R26 track car. The car has undergone extensive restoration and modification and is aimed more towards track use, however is still fully road legal. During our 4.5 year ownership, we have further modified and improved upon the car turning it into a reliable and extremely capable vehicle. The reason for the sale is that my dad is now 75 years old and has started to develop arthritis in his shoulder which makes changing gear painful. So unfortunately, we need to start looking for a semi-automatic replacement.

    The engine is fully forged running a Garrett G25-550 turbo, currently developing peak power at 430.1hp with a capped torque of 360ftlb. To ensure reliability at this power, a custom fuel system with bosch 044 fuel pump and swirl pot has been installed. The car has been mapped by EFI Parts in Runcorn. These guys are the experts at mapped high power Meganes and have done an incredible job making the car a joy to drive and it can really handle the power well. Combined with the slick tyres there are not many other cars that can keep up on track.

    The car will come with 2 sets of wheels:
    • Team dynamics pro race 1.2 (18*8.5, et55j) - Perfect fitment with Pirelli slicks
    • Standard R26 wheels with almost brand new Rainsport tyres for wet weather.

    A decat downpipe is installed however the exhaust has been modified so that a 200 cell sports cat can be easily installed in a matter of minutes with V-band clamps. This has passed the last 2 MOT’s with no problem at all.

    We purchased the car after it had done only 1000 road miles following the rebuild by the previous owner. The engine build documentation was extremely extensive and detailed which gave me great confidence in the build. I am happy to provide all the photos and documentation of the process.

    The bodywork is in good condition but there are a few odd marks here and there as it is mainly a track car. A link to a high resolution copy of the advert photos can also be provided if required.

    The car is well known and fully documented on the forums. BigUno's original thread is here:
