you are wasting way too much money on a build that will get you about 40hp if that. The "performance chip" doesn't do jack shit. also why were you upgrading the injectors to a larger size, this isn't needed with the build you are doing. Also an aftermarket ignition system is not needed for your setup as the stock one will handle just fine. Underdrive pullies are also a waste of money. With all the money you are dumping into this d15b7 you could have just bought a d16z6 and had about the same horsepower, while saving a shit ton of money. The d15b7 is not worth modding.

also all this talk about the heavier B series is false it literally weighs like 40 pounds more than the D series and won't disrupt your suspension setup one inkling. Also a stock b18b will put out way more trq. for about 1000 bucks which from your list is less than you are gonna spend on your paperweight you could slam a b18b in there and have WAY more fun. Also it is much more apt for boosting down the road.

yes you "can" use an older CRX tranny but you would need a cable to hydro conversion kit as the old transmissions are cable clutched while your car is hydraulic.
