The last 96 SV engines had a split sump. The gearbox now had its lubrication system separate from the engine, which allowed the use of the appropriate types of oil for the gearbox and the engine. This also alleviated concerns that metal shavings from the gearbox could travel into the engine with disastrous and expensive results and made the application of an optional LSD far easier.There was a misprint in the SV owners manual indicating bigger intake valves in English size (but correct size in metric). The intake and exhaust valves in all 4 liter V12 Lamborghini engines remained the same throughout all models. This intake size misprint carried forward into the Espada 400GT and Countach LP 400/LP 400S owner’s manuals as well. Easy to forgive when you see the masterpiece Lamborghini had created! Everybody makes mistakes…The P400 line continued with the one off Miura Jota, built in 1970 as true race car, a V12 3929cc with 440 hp. Good for a top speed of 186 mph (300 kph)! This Jota was created on instigation of Lamborghini’s development driver Bob Wallace. He created a test mule that would conform to the FIA’s Appendix J racing regulations and the Jota was born!
The chassis and engine of the Miura were transformed by some extensive modifications, which resulted in weight reduction. This was realized by replacing several steel chassis components and body panels with the lightweight aluminium alloy Avional. Also the side windows were changed to plastic. With lightweight wheels added the finished product was a staggering 800 pounds lighter than a regular Miura, 890 kg (1958 lbs).The Jota received a front spoiler and the headlights were replaced with fixed, faired-in units. Wallace substituted two smaller sill-mounted fuel tanks for the single larger original unit. The suspension was reworked and made wider, becoming 9 inches at the front and 12 inches at the rear. The engine was modified as well to produce 418-440 bhp at 8800 rpm, with an increased compression ratio, altered cams, electronic ignition, dry-sump lubrication, and a less restrictive exhaust system.
