96 7afe (M) into a 95 7afe(A) celica., question reguards to swapping it over. Options

[mandrek]

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.

its harder to fool newer ECUs into accepting a tune, so id keep the older stuff.

was planning on using a greddy ultamate e-manage.... hmm.. i was also under the impreassion that due to the increased computer control on the ignition timeing on the obdII that the greddy ultamate e-manage would work better looks like i got a good bit more reading to do..

ive done alot of research already, but most of it was done a few years ago and my notes are kind of all over the place,... i've also re-read all of big F/I threads, (steff, oobi, hafkai, smaay, presure2, etc) and have a solid plan of attack on my project, but one thing that i have not seen too much info on was just what is being discussed here, the big difrences between the OBDI and OBDII... from all that i have seen suggest that when using a simple fuel trimming device (such as the SAFC-II) that the OBDII IS harder to "fool", (i definatly agree with that statement). but when using a better piggy back system (as in the greddy ultamate e-manage) or even a stand alone system, that all of the additional inputs and other changes in the OBDII system (as a whole, not just the 7afe/celica) offer better controll through the ECU.





And back to the root topic, from the feed back that i have been getting it would seem that i will have to swapp it all over anyways... i still need to get the second car here (currently one car is here and the other is still 200 miles away), but when i get them both here, side by side, ill take pix and post any difrences that i find in reguards to harnes, ecu, etc.. if i can get away with not swapping the body/in-cabin harnes (mainly looking at the ecu side here) i would be very happy. it will save me soo much time.
