Yes Geoff, that is correct.

Unfortunately, the 2.2 to 2.5L swap would put you into SPC. Stick with the 2.2 and dominate SSC!

ok thanks now time to tear this motor apart and get some pistions. so do you have to run cats in ssc beacuse bolth on this car are full of oil,fuel,and carbon due to one of the ring lands breaking and sending all the oil out the tail pipe,

From ST rules:

Aftermarket headers may be used. Muffler use is required, but type is unrestricted. Exhaust must exit behind rear
wheels and outside the body. Exhaust tubing size is unrestricted. Catalytic converters must be used in cars originally
equipped with them. Non-stock replacement of the catalytic converter is allowed.
