hey whats up....so i gotta 99 civic hx.im swapping a y8 head with the y5. i have the head and intake manifold, im also getting a p28 ecu and a obd2 to obd1 conversion harness. im also getting arp head studs and new gaskets for head and i.m. and im getting the ecu chipped and tuned once its on. anything else i need to do for it to run completely normal. any suggestions/comments would be appreciated, and if ur just gunna hate then f$*# off. dont go off topic like eveyone does

 

remember running a p28 you going to have to swap to a 2 wire iacv as the y5 has a 3 wire iacv. i dont understand why ur using arp head bolts unless ur going turbo and need to torque the head down alil more to avoid head-lift.

 

im using them because i got them for free. and should i go with p28? or p2n i think it was. and just stay obd2. it may not be p2n but its somethin like that

 

either way if u run a P2P ecu ur gonna need a 2 wire iacv as the HX still had 3 wire its not hard to do there are many write ups on it. emissions wise its easier to run obd2 but p28 u can have chipped and tune better

 

ok cool. ya thtas what i heard. and i read that if i do do obd1 with p28 i have to change my o2 sensor from whatever it is now(5 or 7 wire) to a 4 wire there for i would have to change my wire harness? thats wat he said
