800R Conversion


Our 800R conversion includes not only engine components but a plethora of other supporting upgraded modifications. When our builds go above 750R we use only 'the best' forged engine components supported by our relevant clutch kits and gears which can handle the severe levels of power that we can generate, these builds are very bespoke materials used are usually very exotic and from the best in the industry. The end result of this conversion creates a vehicle which will outperform the latest exotic performance vehicles.

We can also tune on a variety of management platforms, Cobb, ECUTek & Syvecs.

We are known for building powerful GT-R's which prove themselves time and time again on the tarmac. We are frequent visitors to Santa Pod and you'll often find our GT-R's competing the UK drag racing scene. We don't build powerful GT-R's to be powerful and fast in environmentally controlled dyno rooms... We pride ourselves on building them to be exceptional performers in real-world environments.

Due to the competitive nature of these builds, we keep the actual components used close to our chest, but we are happy to discuss options as well as providing a quote for this 'level' of tune over the phone and via email.
