from a 1.6L to a 1.5L engine
i just got my wifes car engine replaced with an older OBD1 engine. the car originally had a 1.6 engine 96-00 (OBD2 engine) but due to not keeping up with maintanence the car overheated alot and one of the pistons got a crack and anti-freeze fluids started going into it. the waterpump cover was also melted onto the actual engine screws. so anyway i ordered me a used engine with 45k and 3 month warranty and had my mechanic put the engine in for me. as a result the company sent me a 91-95 OBD1 engine wich is an older engine. all the wiring was different and my mechanic told me that it didnt have place for the knock sensor. so he told me we would have to send back the engine to get the correct one. i called the company and they told me it was becasue the engine was from japan but that it was the same..."supposely"..so i had my mechanic call him they spoke. and my mechanic ended up sawping the intake manifold and solenloid valve. he also did my suspension .tokico illuminas shocks & springs 1.5" drop.
i got my car back yesterday adn it runs good and the ride is smooth. the only thing i noticed was the idling was kind of high. other than that nothing at all..
now i wanted to know if that was a good idea. and if anyone has any previous or any experience with this type of set up before. will it damage my car?

Was the old engine a D16Y7 or a D16Y8?
If the old engine was a D16Y8 and the new engine is a JDM D15B, you should be able to just use the ECU you have.
Also, check out your Idle Air Control Valve and Fast Idle Valve. IACV is on the back of the intake manifold, FITV is underneath the throttle body. I used to have a busted FITV valve (coolant was coming into the air ports) and the idle was pretty high until I fixed it.
Check for vacuum leaks.
Is the idle unstable too, or just high? Does it always idle high or just when first started?

Did you have to do splicing at the distributor on the D15B, to get the wire harness to work?

get a OBD1 conversion harness
and a D16Z6 ECU (P28)
