ok, im kind of a newbie to hondas. but i was just wondering what motors would be a direct swap for the 89 crx HF. im probably going to pick up the car this month, and it has bent rods, so its probably not worth rebuilding, or is it? but anyways, i just wanna know what other motor would go in without swapping axles, tranny, wireharness or ecu. or atleast a swap that i would have to swap as little as possible. i know the HF has the d15b2, but could i just drop the 89-91 SI motor into it without swapping everything else?

 

you can get:

d15
d16a6
sohc ZC
dohc ZC
these will bolt up directly with minimun to none at all.

d16z6
d16y7
d16y8
same thing, these will bolt up directly by retaing you stock trany/mounts/others but with some more work to it.

or you can go krazy and do a B series swap.

 

I would hardly call B-series crazy.... K series, H-series.. or possible F-series... thats crazy.

 

is there even an f series,i thought the highest they went was h series

 

f series came in sohc accords...maybe something else too

 

S2000 is an F20, right

 

F20C is for the S2k
There is also a DOHC F20B (everywhere but USDM)

 

do a b16a1 but if u dont want the hassle of a b-series do the dohc zc swap decent power and cheap price tag
