USDM gsr 170hp with a 10.1 CR. What if i.....

put the mugen/spoon headgaset on the car which is suppost to raise the CR like .4

would i be closer to a JDM GSR which is 180hp with a 10.6 CR?

just wondering because don't really know what the difference is with the JDM GSR and the USDM GSR.

nope.
Thin headgaskets are overrated on the point factor. If you put a mugen or spoon gasket on, your CR will bump up to approx .2 points.

but yes, 10.6 is the CR of a JDM SiR-G (of course we like to call it a JDM GSR tho) engine.

The biggest differences between a JDM & US GSR is mainly the pistons, optional LSD transmission, and ecu tuning (JDM P72 has crappy programming, US P72 ecu is better to use). Everything else is virtually identical.
