It is hard to say. It depends on the current condition of the piston rings. Once a compression test has been performed, then a decision can be made how much boost you can safely put on the K20a-R (11.5 comp.) engine. From what I have read a healthy used K20a-R engine can handle low boost levels reliably - maybe 12-14 psi.

A leak down test would also help out as far as evaluating the engines health. 11.5 is pretty high compression so I would take it to a reputable tuner if you do put a turbo on it, but it’s been done many times before.
