I have a 2011 accord with the r20a3 engine, I'd consider installing a turbo. How much power can the stock internals handle? Which turbo should I go for?

 

Hi, I've got a 2010 model. I am looking into doing the same. Have a look on this web site and it might send you in the right direction. The R20A is basically the R18A with a longer stroke crank in it.
