hi i was wondering if the h22a7 euro r accord is a straight drop in the 4th gen lude and what kind of modifcation needs to make it fit and also how about the ecu what ecu would i need to make it work i mean isnt it obd 2 or can i convert the harness from obd1 to obd2

This is bolt on swap. You must only choose if you want to be OBD2 or OBD1 (h22a7 is obd2)

bump is it worth the money i mean how much power to the wheels you think

@ries

Does anyone have dynos of the Euro-R ecu vs. an OBD1 P13?

euro-r ecu has electronic power steering..so I doubt it unles someone did it over in Japan...

H22A7 is the Type-R btw..but it has EPS as well

just curious but what do you mean

so this mean it will not work also is there any ways to make a copy of the ecu fuel mappings and timing mapping

The idea that since your not using the Electric Power steering unit in your lude, it will throw a CEL. Thus making you run in limp mode = dumping fuel and making your perfectly new swapped motor run like trash. If i were you i would go hondata, run one of thier reccomended chips, and when your ready you get your **** tuned by a good tuner and make it run real nice.

I was actually told that my 94 h22a came out of an accord, is this true/possible?

@ries

My friends have swapped the H22A7 into both a 90-93 Accord and a 93 Prelude... using the Accord-R ecu. There were no issues with the EPS throwing a CEL. The only problems were with the 3 wire IAC which was eventually wired up correctly.

Well there ya have it, from the stunnas mouth @ries.

HEY!!!!!!!!!!!!! IMPORTANT QUESTION!!!!!!!!! how did you wire up that 3 wire IACV sensor!!!!!!!! i'm doing an h22a7 swap into a DC2 integra.. and i just left the black wire out cuz i figured it was just a ground.. and if it didn't work, then i would just ground it.. but yah.. plz tell me what you did for wiring on it. Thanks.

Are you using the euro R wire harness? i used the stock LS wire harness and bolted up a civic ex IAC. The iac is kinda zip tied to the heater lines and i made block off plates for both the iac and the intake manifold and ran silicone lines to each. pm me if you need more help.. although i don't remember much about the swap. i dynoed 195/149 with a horrible tune and gsr timing map. i recently acquired a h22 timing map and it is totally different so i am going to go back tune again and see if i can get more torque. that was also on a stock h22 header with a large 2 inch collector

edit i am also using a p28 also

@ries I wonder who did that?You also forgot that they did it in a 99 Civic Si
