For Sale: Mint 1975 Mazda 808 (RX-3) with 13b turbo conversion

A lovely little 1975 Mazda 808 RX-3 conversion has popped up for sale on social media, featuring a tuned 13B turbo engine and original reconditioned interior.

Based on the Mazda 808 sedan, the car features full RX-3 trim conversion with a 10A steel front end, complete with rotary badges. There’s also a 13b turbo conversion under the bonnet running an extended port, Precision 6766 ball-bearing turbo, and a custom Dynamic Metalcraft manifold, cooling package and oil filler neck.

There’s also extensive fuel work, such as a Dynamic Metalcraft 100L fuel tank with three Walbro 470 fuel pumps, Speedflow filter, with radium fuel rails and E85-ready fuel lines. Fuel is then supplied to the engine via four 2000cc injectors, also E85 ready.

Everything is controlled via a Microtech LT-16 computer, as well as Haltech coils and flex fuel sensor. Speedflow braided hoses are used throughout, with clamped intercooler piping, and a Pac Performance pulley and belt, catch can and engine mounts.

This is the real deal and should go hard indeed. It also would be quite a lot of fun to drive with a five-speed manual gearbox (from a series 5 RX-7 turbo), running into a HiLux limited-slip diff with 4.1:1 gearing. Some hardened 28-spline axles are used as well to ensure longevity.

Best of all, the complete package looks original, even down to the steel wheels. The interior has undergone reconditioning, but the theme is very original. That is, aside from the Microtech dash and 3D Motorsport display to keep an eye on things.
