luv the sound of a 4 rotor and agree it would be awsome but and if you can afford it go for it but if moneys an issue go a 20b would be much easier and way cheaper
Ive been rallying a rx4 with 13b j port motor for 6 years never touched the motor since rebuilding it plenty hp cheap and easy to look after though it does luv clutches would be on my third now and the ceramic race clutches car is competive with wrx v8s
Think its how you look after them that counts always warm before reving dont rev over 9300 or they will twist cranks
had a cousin got 160,000 mile out of a rx3 12a never touched it used to start it up have breafest then go to work
