That is quite the handsome power increase. From 100hp to 140hp. I bet its pretty revvy.

Nice is nice, but for 8000$, you can almost buy another micra already LMAO

Nobody said tuning was cheap

Cool. I was talking about this kinda mod.

What mines has done here is taken hr15 short block
Attached hr16de piston and connecting rods to the hr15de crankshaft

The stroke and bore remain the same, the hr16 has shorter rod. But taller piston height. So they share the same profile which different fulcrum.

This changes the characteristics of the engine.
I believe they have a stock hr16 head and are just upselling the factory finish on the hr16head.
