Hey everyone, I have some questions about my civic and specifically my R18A1 which is in my 07 civic. I originally planned on taking the R18 out and putting in a K20 then boosting it. But I recently went on a trip with my friends and was able to keep up with my friends even tho their cars (89 Prelude, 91 EF with tuned Japanese SI Engine) are making more power than mine. pleasantly surprised with the R18 I thought Id ask if its worth the time and money to boost it. So please tell me! those who have boosted the R18, how much HP can the block handle, and was it worth it? Thanks for reading
