We started trading in Cambridgeshire, and recently, in 2025, moved to our current site in Ruskington, Lincolnshire, our workshop and parts warehouse are situated on a two-acre site.

We first began building re-power conversions for Land Rovers and have since diversified to offer various products from engine parts to complete engine conversion kits. Our current main line of work is rebuilding the Land Rover 300Tdi as 2.8L, and the sale of transmission adaptors.

Business is efficient and professional. Request for quote answered pronto considering Christmas period, and parts received in Australia one week after payment. Parts packaged extremely well to avoid damage to major gaskets. Very efficient company.

What a great company, a first class service as soon as I told what the problem was he showed me the problem and explained how to sort it out. Very helpful and very professional all the time. The only small problem is where his premises are located if you have no transport. Will be using him again.
