Since our previous article Hartley Engines finished building Jaron Olivecrona’s 1GZ-FE V12. The engine is now sitting nicely in Jaron’s Nissan S14. The engine features CNC ported heads, custom chams, larger valves, and custom 13.5:1 compression pistons. We can expect output numbers soon when it’s dyno tuned but until then enjoy the billet goodness.
