One of the first in the country, this YB engine has a very wide power band
and very low weight. This engine specification would be a fantastic in a
rally car.
JEMS
have produced the system as a kit for the Mk2. Escort. Using Reiger dampers
the kits are custom produced to suit each car.

Jon’s career started as an apprentice at a Rover V8 conversion specialist
learning all about steel fabrication and built himself a spaceframe V8
2CV!
Building an engine and the importance of good preparation “engine etiquette” was learnt with Goodman building Metro 6R4 engines.
Car handling and set up skills were learnt on the job racing in the Vecta Ford Championship for 11 years and working for TVR’s racing division building TVR race cars and their engines from scratch. Taking feedback from the drivers and translating it into race winning cars was part of the job and it is a skill Jon uses on JEMS customer’s cars.
Jons experience is vast, he has worked for UK Touring Car teams, Australian Touring Cars and has also worked on Drag Racing cars, European GT cars (with the focus on endurance as well as power) and Historic race and rally cars. Jon also worked for Knight Racing Services, the top V8 tuning company.
A good engine builder has an immaculate room for engine preparation that’s a fundamental. The JEMS main workshop is almost as clean.
Part of the JEMS experience in an open-workshop on Saturdays when customers
