first off, dont listen to him on the price of his turbo setup, he may be 100% correct in what it cost him, you can be asssured that it wont cost YOU that much, especially when done with good known parts, sure you can pick up BOVs for 20 bucks, but they are used and not a good known brand. its alot of research, and alot more parts to buy and know ALOT about. i think anyone here who has done a turbo setup that was custom., that it was not easy your first time to find all the right parts, and not only the right parts, but to know what sizes work together well.
you got a bit of an odd opinion, a swap, or a turbo on your already existing integra. #1, if you get an EG that costs money, you do a swap, that costs money.
you keep your integra and go boost. either way both routes are gonna cost you a healthy amount of money. these guys are absolutely correct that a b series is never enough power. when you first drop a b16 or b18 into an EG and go for a rip, you're gonna think, this thing is fuckin fast, and sure it is, from what you were driving before, but soon you will crave more.
we dont know the extent of your knowledge or how capable you are of working with cars and ecu's and wiring in general. ill suggest this to you though, as its the route i have chosen and i will tell you why i think its one of the better ways to go.
either keep your TEG or get an EG. EG being the better of the two. do a b series swap, preferably a b16 because of its potential, but a b18c1 (GSR) has just as much potential. now you are cookin, youve got a good chassis with lots of aftermarket parts available to it. youre gonna think its fast, and like i said, it is, but not compared to most other "fast" cars. so now youve spent a good amount of cash on the car and the swap. if you're still lookin for more power, save some cash, then start looking into boosting. a b16 or b18 can hold a good amount of boost stock, assuming the motor is in good shape) make your own or buy a kit and boost it and make as much power as the car will ever need. what i mean by that is, on a stock chassis, 250-300 hp is all you will really need for the street, after that, its traction issues and its time to modify and upgrade that chassis. ive done this exact thing with an EG chassis but a del sol, not a civic, loved the b16a2, but needed more, boosted, and now ive got it. now if i wanted to go any faster, its time to start race team haha. so to build a good reliable car, get a powerplant that is reliable itself whether stock, or under boost. the moral of this would have to be, plan for the future. what i mean by this is, i do swaps for a race shop here in toronto, and i see guys come in and they want that ever so loved, TYPE R, and they spend the huge bucks to get it, we swap it in, and just like a b16, its fast at first. but wait, now you want more power? i wouldnt suggest boosting a TYPE R for significant/reliable power gains. see what im saying? you got tons of options and alot of ppl have gone alot of different routes, research your options and think about what you want, a daily driver and fun car, or track car to put some awesome numbers down. lots of options out there, and each one suits a different requirement quite well! again all this is MY OPINION only based on EXPERIENCE not reading or spreading the word, other members feel free to offer your own as well!
