You can't just bolt on a turbo and go from there. If you want to do it right here's an example.
the axe effect
The non turbo PT engine is weak and needs to be upgraded internally to run more than 9-10 psi.
Unless you or someone else is very experienced you'd probably be better off buying a PT turbo.
As for getting more power for a non turbo engine, good luck. Not really worth the money.
