Trackday Performance has many years of motorsport knowledge. This means that we can offer you the best advice on tuning your engine. Whether it is for racing, rally, track or road, we will most likely have done it before many times, and if not, we will have done something similar enough to approach your job with the skill and care to get the very best results.


At, we offer first class mapping and nothing else. This policy unfortunately means that sometimes we might have turn a vehicle away, on the grounds that the engine or drive line is not in good enough condition to allow us to map it properly on the day. This may seem harsh on the day, but it has proven time and time again the best policy. Customers who we advised to fix problems regularly return and thank us for stopping them wasting money by having a costly mechanical failure at an event.

From KevMoran-GTR

We provide engine building services for mainly Japanese engines. We are regarded as one of the best engine builders in Europe, on the famous RB range of Nissan engines. We have built and tuned may of these engine to 250 bhp per liter. We also build the full range of SR engines used in the Silvia range of cars. We carry most of the parts in stock at all times and can provide very cost effective rebuilds of these great engines.

For motorsport, we specialise in the Honda B-Series and K-series engines. We have built and tuned may B-Series engines for stage rally and track use. We have been awarded by many class wins at national level in rallying. We know what parts to use and how to make the engines last.
We have developed the originally front wheel drive K-series engines for use in rear wheel drive applications – MK2 escorts. We can offer these units complete to drop into the car with a bell housing that will allow the use of all the popular RWD gearboxes – tractive, Quaife, Selhom and more. They are available in 2 capacities at the moment: 2 litre and 2.45 litre. They have proven that they are more powerful than the mighty XE units, and with amazing Honda reliability also.
