ok so i dont know much about b series but what do i have to do to swap the b18c5 in a 2000 civic si? wireing,ecu,mounts, that kind of stuff thanx for your help

2000siturboR

bolt the motor in and plug in the ecu. its mostly all the same

rsxdc52002

i got bot ecu's which is better? and do i use the itr motor harness or the si?

93egSLEEPER

you have the ecu to the itr and the harness as well? if you have all that EVERYTHING is completely plug and play as well as just bolt in.

i have a complete 2000 civic si with everything and i have a complete 2001 itr car with everything so what harness and ecu do i use?

93egSLEEPER

the ITR wire harness and SI harness should be the same... they are both OBD2 DOHC VTEC harnesses so you shouldnt worry about swapping harnesses. I would use the ITR ECU with the ITR motor it will be better preset and wont need to be tuned right away

so what kind power does the itr motor lay down and so the itr ecu plugs in the civic si?

93egSLEEPER

The ITR and SI are both OBD2 which makes all the plugs the exact same. all you have to do is unplug the SI ecu from under your dash and replace it with the ITR ecu

the ITR will throw down something like 198hp 150tq at the crank...i think (not 100% sure off the top of my head)

ok so i was also thinking of doing a build with the b16 si head since the bottom end is crap is the b20 a goor idea "for the future"?

rsxdc52002

also i will have around 1500 cash what can i do for more power on the b18c5? it already has ihe

93egSLEEPER

that my friend is your decision. do you want to stay NA or would you rather play with boost? since you have the ITR motor i would keep it NA, build the head with new springs/retainers and throw a set of stage 2 cams in it.

As for the b20 you have to ask yourself the same questions... what is your overall goal with the car. do you wanna build a b20-v?

rsxdc52002

true im not sure about the b20 thing i have just heard about it in the past and was wonderin im sure this wont be my last honda i already have 2 many projects as it is so i will prob. hold of on the b20 i might just put it my k24a2rsx but dont know yet i guess im just throwin ideas and tryin 2 get some back well i thank u man alot of other sites wont help me so thanx
