how well does a R18A1 do with boost on a 2007 honda civic. thats the stock motor and I wanna know how much power the block can handle and if its worth boosting that engine. I just need to know if I should K swap it instead or if that motor is worth putting money into

 

If you have the cash, go with the K20. I keep reading that rtes R18 block from those years are weak and not good for induction.
