I was getting ready to buy this Type R motor and the guy gave me a option to have a p72 or p73. which should i be getting? my car is a OBD1 Setup. and if these are OBD2 then ill need a harness which is fine. i just need to know what to order. i do have a chrome chipped p28 if that helps but i get a p72 or p73 with my swap package. im going to try to order it tomarrow so if you can respond asap.

thanks!

 

i say just get the p73 n keep that or sell it
then go get a typeR basemap on the crome chipped p28

 

Agreed. Get the ECU that goes with the swap (P73). Seems pretty stupid to get a GSR ECU (P72) when you have an Integra Type R (P73) swap.... Not sure why anyone would offer to do that.
