if u get it tuned sure. idk specs on the p29's but with p73 pistons in my GSR (10:1 compression bumped up to about 10.8:1) and everything else stock including it being untuned I still managed to pass smog

So that means, if it swap out the pistons without it tune, i would still pass. man i gotta try this.lol
