What I think , as per what you said in the other thread and the current one, you should not go for absolute power, so around 150 HP should be good so look for a decent r18 is what I say, because fitting aside, everything should be available relatively easily , this has been used in the civic from the past ..... Since it's been locally made, so mechanics will be able to trouble shoot, it makes in the neighborhood of140 hp but it's heavy and will require some tinkering, others will disagree as it is not as exciting and rare as a b series or a k series bit it's the best for a daily fast ride
