need help with a tranny swap

i have a 2000 civic ex auto tranny...i was wondering can i do a 2000 si tranny swap(manuel) to my car and how much u think it would cost? and will it be worth it to do.. and also my boy told me i can get the si tranny swap but with an auto can that work?

well the cost would be astronomical, secondly its not easy. it'd be easier to sell your car and buy a manual version.

si tranny is a b series tranny, wont work with your ex

ok thanx.. but i got another ? i want to dump a b16 or any dohc in my car my boy said i cant do it with out swaping tranny with a more better one can i do it with out chagneing my tannny..i really need a dohc

No you can't use your existing tranny on a DOHC motor. I'm assuming by DOHC you are basically refering to a B-series motor (b16a, GS-R, LS) and in that case only a B-series tranny will work with that motor. You have to use the tranny for the motor series you get.

None of the D series SOHC engine parts and accessories will cross over into the B series, and vice versa. Also, there are two different catergories of b series trannies, cable and hydro.

the 00 civic EX just screams 'chick car' - I know this, because I own one:

i have the same car, in a manual/5-speed...why do you have to have an SI tranny? You could do the entire swap, considering the SI and EX are nearly identical in terms of the body, but I think it would cost you more than the car is worth, especially if you can't do it yourself.

Keep your car stock, keep the miles off of it, sell it to some female and just get a used SI.

ok thanx for the info. but ive already done some mods to my car.example intake exhust and some interoir work .im trying to lean away from selling my car.plus a si around where i live wont be mine for long so there is no ponit of getting one.my boy had a 00'Si for only a day. is there any way i can get alot of perfromce outta my car wut about fixing up my current tranny with those parts from level 10 such as the shift kit,the touque converter etc.. do yall have any info about those parts

the only DOHC motor you can get and use your tranny would be the ZC, but they are from 88-91 JDM CRX SI's, and most states wont allow a motor to be put into a car thats older than it.
