I've recently bought a 2010 Lancer GTS and i want to turbo it. I have two options at the moment which is to go with the EvoX set up or the Ralliart set up. Correct me if I'm wrong but for the EvoX minimum PSI is 11-10 and for the Ralliart is 7-8?

Ive been doing a lot of reading and it's come to my awareness that i will need to upgrade internals if i go with the EvoX set up since i can damage internals.

I've read that Caliber SRT pistons and rods may fit? I can't find many options since my understanding of cars is very minimum but i wan't to learn.

Questions:
1. How much PSI can my stock 4B12 engine take?

2. Will i need to upgrade internals if i go with Ralliart set up?

**3. If the SRT4 pistons and rods fit, will my stock cams fit?

Any suggestions and feedback is appreciated. Thanks
