The S20 engine is a straight-6 which is well known for powering the legendary GT-R when it dominated Japanese motorsport. Regarded as masterpieces, S20s are highly desirable engines. This is a complete example that has been extensively tuned. Displacement was increased from the stock 2-litres to 2.6-litres, providing a more torquey feel despite the high-revving nature remaining. Naturally a number of reinforced parts were installed to cope with the additional power.
These 2.6-litre engines are rare finds and this one is in good condition and it has only been used for a few hundred kilometres.
