WC Engineering specializes in the development and fabrication of performance parts for the 4-cylinder Lotus Esprits and early Toyota MR2 automobiles. We are particularly known for turbo upgrades and custom engine work.

Company founder John Welch "tweeks" and races his own 1991 Lotus Esprit SE and 1987 Toyota MR2 Turbo. He works with many other club racers to further develop and enhance their high-performance cars.

Many of the company's performance upgrades are available for purchase as kits, complete with detailed, illustrated instructions. If you need advice on which parts are right for your automobile needs, even if the upgrades you are considering aren't ours, or you would like to discuss a custom project for your car, feel free to call or email us. WC Engineering does service work ranging from simple diagnosis work to complete engine and transmission overhauls on an appointment basis.

WC Engineering has campaigned cars in many local track events and three entries in the Silver State Classic open road race. John is an accomplished mechanical technician, an experienced road racer, and has worked as the Data Engineer on a professional CART team.
