PRL Now Sells Upgraded Rods and Pistons

[FK7Hatch]

I'm still a bit unclear on what the 0.5 mm larger bore size and lower compression does. Is anyone familiar with this?

Cylinder capacity aka displacement is the volume of the cylinder... Aka bore x stroke.. they're increasing displacement... Lower compression means the engine itself makes less power, but with a turbo you can cram more boost without pre detonation making more power

Keeping it quiet huh... Forged internals from the fit to the new civic isn’t a bad idea... just like S2k rotor and itr brembos plug and play.

The Fit/Jazz is the L15A not the L15B5 or B7. Parts are not the same, the Rod is slightly longer, and the piston will not interchange.


As for the oversize pistons, the main reason to use these is it allows the machinist to fit the pistons to the bore much more exact. Every piston will be slightly different, and every bore slightly off so if you just get "stock fit" its possible you will leave power on the table due to fit up. The added displacement is very small, but an secondary benefit. Compression options would be for someone looking to run and very large amount of boost, most likely on pump gas. As the factory higher compression has a chance of detonation on high boost with pump gas.

Not sure what the different bore sizes or compression ratios mean, but I'm guess that this is all good stuff!

No kidding. You quoted a post from two and a half years ago.
