Can i still pass smog w/ ctr piston and camshaft on a gsr block w/ b16 head? Or itr piston and itr camshaft w/ gsr head? Which combination of this is better and has more power? I know i have to buy a high performance radiator cause too much compression.

 

you need a radiator for compression??

 

yes cause without a high performance radiotor and too much compression, the car will run hot. So you need a performance radiator to lower the temperature.

 

 

they're all oem parts so i don't see why it wont pass smog. it shouldnt make any big difference in smog levels
