@ausi, k20a type R all the way since there is no k20a2 in pk, otherwise the a2 was the choice....no there are no extra maintainence issues with a turbo, the response of D with a turbo is too good, ive turbod my D17 and it is amazing.... all u need to do is not be a jackass and maintain it well like change oil+oil filter a bit earlier than u wud on a stock car, dont give it to a driver, drive it with manners and ur gud to go...by far the fun of a turbo D can never be matched by an n/a k20....
swap in a d17 and turbo it, i produced 185 whp on a very small turbo on a d17, prior to that i produced 157 on the stock d16w9 that comes in the pk civic wich has no cams or internal support unlike the d17 wich is the japanese one.....
