I bought my 90 DX hatch in September and it is slow, but it was a one owner car and the body is mint. My buddie and I bought a CRX si for $200. The motor is shot, but I was able to get the rims, seats, gauge cluster, tranny, axles, ecu, brand new clutch, and all parts for rear wheel disc swap. Now all I really need is the motor and I pretty much have an Si. I want to do a swap over the winter but I am not sure what I would be getting myself into. I was just wondering how much work really is involved in it, and how hard on a scale of 1 to 10 it is. I would also like to know where I could get a good motor in Minnesota.

Just convert to MPFI and get the resistor box off that Si and you should be fine I think.

 

If I were you I would just stick with the D15, add the Si head and dizzy (mpfi) ECU, and use the Si tranny. Big difference over stock.

 

i agree, no need to swap the entire motor, the gain from 1.5L to 1.6L is not noticable. what is noticable is the mpfi swap, si cam, si tranny. i personally wouldnt swap the head though.

 

Same as above ridden in a friends stock si and a friends stock dx and to me the dx pulls harder. Plus the si tranny on a dx would be fun.

 

I might try the mpfi conversion , but the head of the motor is the only thing bad on it and I already sold the resister box. Changing to MPFI may be a posibility, but I will need the directions if anybody has advice.

 

It's way easier to swap the entire head than swapping a cam.

 

get the distributor off the motor if possible..

here is what me and JOSHWHE used: http://tech.hybridgarage.com/tech/4g...-zc-wiring.htm


good luck and drink lots of beer..

and make sure you clean the mating surfaces of the intake manifold and head.. or coolant/vacuum leak gods will punish your ****.

and when your workin on it.. and somebody honks the horn.. don't hit your head on the bonnet

 

what he said.

if you need another resistor box, i have tons lying around. i'd can ship you one for cheap. PM me.

oh and if you still have means to get things from the crx...get the dash!!!

 

wow, how did you get a crx si for $200 ?
btw, off topic, but why would you choose a ZC as a swap? is the different comparable
to b16?

 

The ZC is a cheap alternative swap and can produce decent power if properly worked. But if you want some serious power I'd suggest a B16 swap. My room mate has a B16 in a CRX DX and kills me all the time with very few mods.
