im planning on dropping an 05 AP2 engine in a MY00 S2000.
i would appreciate it if any1 could give me some tips, things to watch out for, advice.
any extra parts i might need from the AP2. (other than the transmission)?

would the ECU work properly? any1 tried this be4? CELs? any problems?

i appreciate any help.

thanx in advance.

I have a F22c bored to a 2.4l displacement in my car but i cant help you cuz i didnt do the swap. I just wanted to show off. good luck.

 

 

Very slight modification to the fuel line where it connects to the rail, if you use the AP2 rail.

That is IT. Should take you less than a minute to adjust the fuel line to fit.

 

the ap2 engine doesn't seem to have a timing sensor on the intake camshaft...does that throw a code when using an ap1 ecu??

 

Hahaha!

Enjoy the tq, OP.

 

id imagine you would need the correct ecu for the engine, i doubt an AP1 ecu would run the AP2 engine properly...

 

No, it actually works pretty well from what I hear.

 

its not hard. as bill said, the fuel rail is slightly different. i just re-used my ap1 rail for simplicity's sake.

most other parts are interchangable. i did my swap without pulling my a/c compressor - i just unbolted it from the motor and left it in there. when i went to put everything back together i tried to use my AP1 starter, but it did not bolt up correctly. not a big deal, but something to note.

as far as the ECU goes, it should work just fine - though i don't recommend revving your ap2 motor to 9 grand. TDC sensors for the cams work - i'm not sure what maluch had troubles with.

while you're swapping be sure to re-use your ap1 flywheel - it's much lighter than the ap2 one!

 

^^ exactly like TelosHedge stated. I did the exact same thing, minus A/C as I removed it when did the f22c swap. I however used the f22 fuel rail, very easy to adapt. I run a 2000MY ecu with absolutely no problems, just don't over ev, cuz it won't stop you And yes re-use AP1 flywheel, check to see wear and tear, I opted to resurface mine when swapping engine just for peace of mind.
