Guy says the engine is out of a 99 SI, B16 - so I did some research and it seems it would be a b16a2 10.2:1 CR. How is this motor for boosting? Seems like a moderate compression ratio. What kind of PSI would be safe?

 

definitely boost and get it tune... 5-8 PSI would b good.. i would do 7 to be secure and still be real fast
