stock h22a2 yields 185hp and stock h22a5 yelds 200hp
I might be wrong, but arent all those h22 motors pretty much alike? So where those extra 15hp come from? Just ecu or something else?
Thanks

P.S. Searched forums but couldnt find anything on this topic

 

This is the same story like H22a1 and H22a4 in the US. I think it's electronics.

 

Can someone confirm this?
If this is so then I can just take ecu from 5th gen prelude engine and upgrade my h22a2 to h22a5?

 

You can't exchange ECUs as they are different OBD and 5 gen has immo inside... At least not that easy.

 

Ok, I'll do reaserch on this

thx

 

hi guys the rings went in my 1995 h22a2 model and im not fully aware of the rest of the damage yet but have been warned that it might be cheaper to exchange engines i have located a h22a5 model from 1998 lude.... WILL this fit straight into my car????? please help please please please

 

Where are you getting this H22a5 motor from? That is a new block to me???

 

Euro spec H22

 

it is from a scrap yard its out of a 1998 prelude it has obd2 on it mine has obd1 on it the guy said that just change the wiring looms and it should be fine just plug and play supposedly.... Thats why i joined this fprum to find out more anybody know will it fit correctly

 

yes correct euro spec h22a2 and the h22a5 is euro spec too i think.... The wiring looms from the obd1 on my engine should just swap with the obd2 off the h22a5 engine supposedly.......

 

I see...
