engine swap 2.5 to 2.3 turbo

Can this be done, has it been tired? Will all the sensors match up and be in the same places? What resources are out there for tuning? Will the engine bolt right up? Does anyone have a list of parts Im going to need by any chance?

yea it should bolt up. the 2.5 and 2.3 have the same block size. for sensors idk wat a mean. but i think u just tale all the stuff from the donar car for the wireing and all.

I'm not sure what year Ford stop production of the 2.3T. If I see them around here, there usually in the older Ford T-bird coupes from the 80's so no OBD stuff there.

I'll be eyeing this thread, I've been curious lately myself about this swap. -Mike-

there are a couple ways you could do this...

1. if you dont need the OBD 2 stuff then get the engine, wireing harness, and computer and just rewire things and use the turbo computer and wiring harness and everything. this wont work if you need the OBD-2 for inspection or emission reasons.

2. its a bit more custom and a bit more work, but should be able to be done while retaining the OBD-2 stuff. you can get the engine from the turbo, and then use a seperate stand alone fuel management system like MegaSquirt or any other type of stand alone fuel system. this way you can use your current sensors in the motor, and build and wire in the stand alone FMU to control the fueling needs of the engine, these allow total control of the fueling parameters. this will take quite a bit more wireing, however it should be able to be implemented with the current computer and OBD-2 system.

3. another possibilty, which i havent seen anyone doing yet, is trying to use the EEC-V system and program it and modify the programming of the factory computer to be able to understand boost and control the fueling properly.

2 sounds the best but, how much for the standlone? If the 2.3T has all sensors locations as the 2.5 then all you would have to do for starters is just plug in and run a piggyback? the eec-v should read some boost and run that boost until the standalone comes into play.

well, megasquirt is around 200-300 for all the parts then you build it yourself. if you were to use a stand alone setup then it would handle ALL fueling for the engine, not just some of it, from idle to full boost. you would integrate it with the EEC-V and the EEC-V could still run the ignition and timing and the other sensors of the engine. the stand alone would read the MAF and manifold pressure and the crank and camshaft postion sensors and the throttlebody position and O2 sensors to knwo how much fuel and when it needs it, and the EEC-V could still have all its sensors hooked up to know when to spark. and all the sensors could still be left connected for the factory computer so it would know exactly what was going on and wouldnt throw a code. there are a bunch of different combinations that could be done, i mean you could even adapt the spark into the standalone so the factory computer doesnt actually control anything, it just thinks it is which would allow you to retard or advance the timing, add a knock sensor, and do the other things which the factory setups dont allow you to do. but adding ignition controlls to the stand alone adds even more wireing and figureing out of things, but it can be totally worth it if done right just for the ability to have a knock sensor and to be able to adjust the timing parameters.

for info on MegaSquirt go here megasquirt and the associated forums for it have TONS of good informationa nd support, includeing some pre made engine management programs as a starting point.
