Our relationship with Nissan / Datsun cars goes back to the late 70's when we were very active in the racing of Z cars and 510's. We have never stopped racing Nissan / Datsun cars and most of our fastest street cars have been "L" motor powered. As technology has marched on with each new model we have tried to make our modifications more high tech and modern with Turbocharging, Programmable Fuel Injection Systems, Etc., but we still love an old Z car with set of 45mm sidedraft Webers, a header and a 2.5" exhaust. 510's will never die and as long as there are parts available and people who want to build one up, we will supply things for them. So, no matter what Nissan / Datsun you own we can probably help you get more out of it for either the street or the racetrack.
