I have a 96 integra b20b gsr trans and a p75 ecu not sure if it is obd2 or not. How can i tell and will a p75 work on this motor with a low boost t3/ t4 set up. If not which one do i need and also what is the cheapest but reliable way of tuning for boost.

 

If it plugs into your car it's obd2.

You could also look at the parts fiche at acuraoemparts.com and compare the part number on the side of the ecu.

Running a stock ecu with a modified engine sucks in this century.

 

lol... "cheapest but reliable..."

You need a tunable ECU no stock ECu will run that setup.

Do you have a local tuner that you can contact?

 

Totally missed that.

Building/turbo'ing a motor without proper engine management makes about as much sense as buying a $2k set of wheels and driving on them without tires.

 

96 P75 will be OBD2a. You will need to convert to OBD1 with a conversion harness, get a socketed OBD1 ecu and then go get a full wideband tune right from the start. Way too many people skip the most important part of the build.

Cheap out, don't get tuned and you destroy your engine.
