All the new comers that ihave talked to have all told me, if i put the type s rsx motor in my civic, its a type s.. blah! stfu morons.. more to a type s then the motor and tranny. That is like when ppl drop in an ITR swap into a civic and claim its a civic type r..
Read the FAQ, they have a post about this swap into a Civic.
Another option might be a K24. Although this motor does not have the power of the K20, it has quite a bit of torque. And it is certainly an improvement compared to the D17. It will also be cheaper and more plentiful than the K20 since it is found in more mainstream vehicles (base model 2003 Accords and all 2002+ CRVs). But I am not sure which transmission you will need.
