Is the conversion road legal?

Yes it is fully road legal, this was in fact the reason it was first developed. It passes current UK MOT requirements easily without a reverse gear, and the emissions are lower than any tuned A series.

What else to I need to buy to complete the conversion?

You will need a complete Yamaha YZF R1 engine with all wiring, cdi, coils, carbs or throttle bodies depending on year of engine. Engines from 1998-2003 bikes are suitable.

You will also need some form of air filter, we recommend K&N air filters as they fit under the bonnet, are easily cleanable and long lasting. Other parts required are an electric fan and temperature switch. If you are running an injection engine then you don't require a fan switch as the ecu already monitors coolant temperature and provides an output for the fan.

The kit is designed to mate to a 2" performance exhaust Maniflow etc. If you use the twin box system (as our car does) you will pass noise regulations for Castle Combe yet still sound awesome on the road (listen to video!)

Where do I get an engine from?

There are many places where suitable engines can be sourced from, like bike breakers, local adverts or probably the best place and frequently the cheapest is here on everyone's favourite EBAY

How easy is it to wire up to the existing vehicle electrics?

Depending whether the engine is carburetted or injection we can modify your harness to allow easy connection to the original vehicle harness.

What are the performance figures?

0-60 times are around 4 to 5 seconds depending on traction and gearing, terminal speed is about 125 in 6th.

What is the BHP of the engine?

The engine produces 150-180 BHP in standard tune depending on model year. This also means further tuning can be done!

Currently the conversion has no reverse gear, but we are developing a replacement driveline that will house a reverse and retro fit any previous kits.

We can supply gearing for any wheel size you wish to use. Our own cars run on 10" wheels this is only down to personal preference. Please let us know what size your running when ordering

What body modifications are required?

The only part that needs removing is the centre grill support to allow clearance. The bulkhead needs no modifications whatsoever.

Do you recommend any further upgrades?

We would highly recommend you upgrade your braking system as with all the power available you will be pushing the standard braking system to its limits.  You can get away with grooved discs and red stuff pads or fit 4 pot calipers. Also replacing the 4 pin differential with a Quaife ATB makes a big difference to the handling and traction.

How do I get a speed readout?

We currently use instruments from ETB they allow full programming and use a simple magnetic pickup that can be mounted on the drive output from the gearbox. The standard mini temperature and fuel gauges can still be used.
