Hey, you know how the Type R engine is mildly ported and polished from the factory? Does the Type S prelude engine receive any sort of porting and polishing? If not, does the Accord Type R h22a get porting or polishing?

 

[Prelude-S1]

I think the type-s does have a mild P&P

there's a little bit more info here
