35 psi is about the highest you want to go.
You're fine.

3kgsk is a nice mod
Be-careful installing it though
It's a little tricky, best to get with someone that has installed it before.


4kgsk is the same thing, but you also need to install valve springs since it lets the engine spin up more than a 3kgsk
