So I spun a bearing on my stock h23 and instead of rebuilding I'm going to take this opportunity to put in an H22. I have a '93 Prelude w/ 4WS.
My questions:

Will swapping ecu's affect my 4WS?
Will the v-tec sub-harness from rywire work w/ my oem harness?

And I'd like opinions on this ?:
Should I leave my H23 tranny on w/ the H22 motor or get an H22 tranny OR I now have an H22 (m2y4) tranny sitting around that I can use but I am unsure if that will affect anything...?

Your help and opinions are very much appreciated.

 

Swapping ECU's will not affect your 4WS. 4WS has it's own computer and is a separate system.

Just use your H23 harness and run the two wires for the VTEC system.

As for the tranny. I would look up the ratios and decide what you want to do. When I did my swap I just kept my H23 transmission.

 

Agreed,I also have an h23 tranny mated w a jdm h22a and I really like it,I always thought I was missing out on the h22 tranny's,but after driving my friends 95 w m2a4 and a h22,I didnt even notice it,well barely.....maybe its alot different w the m2b4(lsd) than the others but for me it wasnt worth the purchase of a new/used tranny.

The tranny m2y4 will bolt right up to any h22 if im not mistaken,and If u have to swap the motor anyway and u have the extra tranny laying around,I dont see why u wouldnt just throw it on together.Good luck with the swap.

 

Thank You!! i do have 1 more ?
Motor mounts.. Will stock h23 mounts hook up with the h22?

 

its best you get those new. Then you'll have the peace of mind that they are new and dont need to be replaced sooner than later. thats what i did and didn't look back...

 

That is true. might as well do it now. I'm thinking in budget-mode right now so that didnt even cross my mind. Thanks everyone! I think I'm all set.
