hey all i have a few questions that a few hours of idle searches and reading have not been able to help me find the info that i need..
i have a 95 ST auto that had the motor go out on, and i just picked up a 96 manual st as a parts car. right now ALL that i want to do is swap the motor over. JUST the motor, ill may do an auto to manual swap later, but not what im concerned about ATM. now i know that there is a difrence between the two 7Afe's (95-to-96) in reguards to power output from the factory. but what it was understanding was that it was just a tune from the factory, and the addition of some emissions stuff. what i would like to do right now at this point is get my car back on the road. so i was wondering if there are any difrences in reguards to the motor that will give me problems when switching it over, plugs, sensors, ecu-harness, etc.. or will i be able to just pull the motor from the 96, slap it on the auto, drop it in the 95, and plug everything up. and get on my way? i could write more and make this alot more winded than it is, but i want to keep it simple. thank you in advance for any relative info. mandrek. -------------------- |

QUOTE (mandrek @ Aug 12, 2011 - 8:04 AM)  anyone got info on how to identify the diffrences between ODBI and ODBII? OBD2 7A-FE has a crank position sensor to aid in isolating misfires to a specific cylinder and alot more self diagnostics. I think OBD2 also got sequential injection to help with emissions and smoother idle not to mention ALL OBD2 year 7A's (that I know of) have EGR and a different intake plenum design as well as a slightly retuned ecm program for lower emissions, and an additional catalyst right off the exhaust manifold. you loose 2-5hp and gain 2-3tq which isn't even noticeable. OBD1 has no crank sensor, some don't have EGR, some/most only have one cat and one O2 sensor, some have the older style intake plenum, less self diagnostic ability, and the injectors fire in pairs. -------------------- |
