can go or should go. I would not recommend 10.5:1 almost 100% of the time.

9:1 should work fine and many people run 9.5:1 in their stock s14's.

You have many things to consider, like what turbo are you going to use? psi dont really tell us much.

what size turbo dawg!

[fliprayzin240sx]

PSI dont mean shit...turbo you plan on running is whats gonna make or break it. 14 psi on a T25 would not push the same about of air with a GT40.

I would also recommend 9:1 compression, if you plan on running a smaller turbo and shooting for responsiveness vs max HP.

do this
9.5:1
GT3071R .64 A/R

[NemeGuero]

8.8:1

14psi on T28 (s14 sr)
