b16a2 opinion

Contemplating a 16a2 swap in a 4dr 5g civic EX, I was really lookin an 18c1, but $1100 more for an extra 10hp and tq lets be real. I have worked very hard to save up $2k cash, and I am wondering from people who have experience with this kinda thing is there really gonna be a noticeable improvement with a swap? Sure there is an obvious difference with an 18c5 but i don't have $5k. I understand it's a direct bolt in, are ECU plugs the same and everything? I mean, they come out of 5g del sols, which is like a civic front clip w/ no back seat.

I saw that one red coupe ex with the same swap done, was it a whole lot of trouble or did a mechanic do it? I have the help of my dad who's been workin on cars since the 50's, but wiring is a whole nother story unless anyone has any sites that specifically cover and document step by step 16a2 swaps aside from the hybrid honda site.

What do people in japan do about replacement engines? are they manufactured still?
