Sorry man but this doesnt look like you want to do it in a beater hatch. it specifically says " i have a 99 civic ex what swap should i do?" and as for me calling you out on here instead of emailing you…im not calling you out im just making everyone else aware that is responding to you that you are wasteing their time. You should of called me last night that is why i left you my number 3 times! Any ways IMO anything will be a hell of alot better than what you have now. wether you go with the b16 or b18c1 it will still be a fun ride. I prefer the B18c1.
