Ive decided to focus on this particular workshop, R4 Motorsport from Shah Alam. They have been in business for few years specialise in Mitsubishi 4G9x and 4G6x engines. Besides Mitsubishi engines, they also have expertise in Honda B-series engines and Nissan SR engines.
They are open 6 days a week from basic car servicing to engine build-up. Regardless of natural aspirated or turbocharged engines, they can assist both setups and any customers' requirements. Their prices are very reasonable. They are located in Shah Alam district not far from the Kesas Highway exit to Shah Alam.
The compete competitively in Sepang Drag Battle for many years with their own turbocharged 2WD Proton Satria. As you can see from the pix, their latest setup and new paint scheme since the last round which im very impressed.
They plan to run better timings next year with all the results they clocked and developments this year.
All the best to R4 Motorsport.
