engine swap questions
 

ok it's like this, my buddy jared wrecked his 94 prelude and totaled it. the engine and tranny are fine though so i was thinking of buying them to put in my civic. I want to know if thie is possible. i have a 99 civic cx 1.6, but i'm not sure what kind od prelude he has. I know it's not a si and it doesn 't have a v-tec. so i'mthinking it's a f22a or a h23a. are eitherof these motors swapable to my civic and if so what do i need to do to swap them. sorry i'm really new to this:(. thanks guys for help

anything is "swapable", just depends on how many monies u have. i believe that h and f blocks are the same, and should use the same mount kit. so, u would need ecu, wiring harness (obd2b-obd1), shift linkages, axles, whatever exhaust components u would need for it all to align, and prob a lot of other things im forgetting. if i understand correctly, ur main question, even though u may not realize it, is "are there comercially available swap mounts that would allow me to bolt an h/f series engine into my civic?", and the answer is yes.

thanks for the info. i have the whole prelude to work withso i'm sure i can reuse harnesses and i have the ecu and such to work with. i have no idea where to get the mounts all the other jazz. i have some money but probably not enough but it'll be an ongoing thing. is there anything else i may need to know or anything BIG i may need?:confused:

im not sure how much of the stock lude harness will be usable. u need to keep ur stock civic harness if u want everything to still function properly. u wuill need at least an obd jumper for the ecu, and a obd1 jumper for the dizzy. as far as hooking up all the sensors and such, u will have to do some googling. theres plenty of h/f swap intricasies that im not familiar with. it will def be an undertaking, but the torques will be worth it. dont go boosting that ish tho, i think they have frm sleeves. you may experience poorer handling, due to the fact that the engine will now be mounted in front of ur front suspension, instead of directly above it. just keep wearing out google and our site's search function. im sure u will find what u need. good luck mayne! edit: check ebay for ek h swap mounts.

a lot of wiring. honestly the H22 is a jazzy engine. but id stick with b series for civics because they are easier. accords? well hell swap away and it would be sick. but it has been done before. but if your going to do a prelude swap. you might as well do the vtec h22 otherwise its like putting a non vtec b series in there. and why would you do that?

project91, he would most likely be interested in swapping an h in instead of a b because of the much greater torque. i would do so as well, espescially if i were getting a great deal on the complete swap from a good friend. more than likely, he will only go so far as i/h/e on whatever swap he chooses, so the h23 will be the most bang for the buck. also, if it is indeed an f22, bisimoto made 300whp n/a with one last year in a super street magazine article. just saying, dont discount the h/f engines. im not certain that a b series is much "easier". the mounts and axles and such (for the h/f swap) are readily available. all that is left is the wiring, and its well documented on the interwebz...

Have a 99 si swapped b18b1 ... Seems to be stalling out when idol, pretty sure its a vacuum leak... Bigger question i was wondering about future upgrades and what i should focus on, everything is pretty much stock other than air intake lowered and control arms... Should i do exhaust upgrade first or start elsewhere
