152k mile supercharged s2000?

Hey guys so I’m still pretty new to the s2000 platform and I got my first ap1 s2000 about 6 months ago, I love the car and I’m trying my best to replace everything wearing out and degrading on the car (it’s got 152k miles on it) I was thinking about swapping the trans for an ap2 trans for the shorter gear ratios and maybe getting the SOS stage 1 kit just for a bit of extra power( a bit more context for the motor health, I compression tested it and got an average of 180 for every piston which I know is kind of low, my theory is maybe someone boosted it before me, it also eats oil like a thirsty mofucka and spits white smoke when I hit vtec, I called a couple shops and they told me that it was ok) does this sound like an alright idea?
