What did you come up with on the camshaft timing marks at TDC? Are they still just a smidge off? Are they worse than that? Off a little is okay, you'll find that if you change the position of the belt at the cams by one tooth to either direction that it only gets worse. Sometimes a "best fit" is all you can hope for with these engines. Is it the belt? is it factory tolerances? I don't know. At any rate... you should be able to remove the upper covers and see that both of the allignment marks at the top of the cam sprockets are still lining up.
as that guy in Lithuania says... change the crank angle sensor and cam angle sensor. (it's worth it since you have those from your old engine) You said they looked slightly different.
Compression test? Even with the crappiest of compression in all-but-one cylinder will allow these engines at least to RUN-- quite horribly but will still run. A basic tester will only cost about 25 bucks at Sears, auto-zone, Kragen, or Pep Boys. (or whatever auto parts store you may have in Michigan. If you're dying to know if you have a dead cylinder or two--go ahead and buy one and check the compression.
These engines are bulletproof and the ej22 is a non-interference engine. There is no possible way you have messed up the engine by changing the belt incorrectly.
My point is that you shouldn't have to go get another engine. I've always got my eyes peeled though.

Well, what was originally a smidge off turned into quite a few teeth off after turning it over a bunch. it looks good now, and ive turned it over a lot and it still looks good. i just pulled the crankshaft t-belt sprocket off the 1.8 , and it looks to have a different tooth pattern than the 2.2, so i will definitely change that in addition to the sensor itself. So ill go mess with that this weekend and keep my fingers crossed. i cant thank you enough for the advice.

Keep the main crankshaft timing gear from the 2.2 on the 2.2 engine. Swapping the 2.2 gear for the one that you have on the 1.8 will likely cause more problems.
You don't want more problems.

in my case 1.8 crankshaft timing gear had 7 triggers, 2.2 had 6 triggers, and that's why motor get misfire with 1.8 ECU

I was thinking that there was fewer teeth
I thought there was a different number of teeth on the 1.8 gear than on the 2.2
I don't want to perpetuate bad information. Sorry bout that.

ok, i swapped over the crank sensor, crank trigger, and cam sensor from the 1.8, and it ran for about 5 seconds or so before sputtering out with a nice little backfire. every time i turn the key, even if i give it a little gas, it runs for 5 seconds then dies. CEL is on, but no codes. and it runs pretty rough, but its progress! any idea on why it wont stay lit?

fuel pressure, fuel quality, fuel quantity
Are the fuel pressure lines and fuel return lines reversed?
You're close. Keep trying.

i checked the fuel lines, and theyre all going to the right place. i have had the airbox off this whole time to give me easier access, any chance that is affecting this? happy thanksgiving by the way!

well hallelujiah! i think i just answered my own question- put the airbox back on, jury rigged a hook up for the IAC hose, and as long as i rode the gas a little, she idled! a little rough, but still it ran until i let off the gas. which i am guessing is caused by way to small an intake hole (1/4") for the IACV. awesome! and thank you for walking me through this.

I think the inside diameter of the hose leaving the intake tube is around 3/4 inch. It should be the same as on the IACV end I would think-- just a thought. Congrats!
instructorbill, yuo said that you done this 1.8>2.2 swap, how runs yors 2.2 on 1.8 ECU, have any problems, like rough idle, rich A/F?
I'm running:
2.2 motor
2.2 injectors
1.8 ECU
1.8 intake mani and exhaust
When i put 2.2 injectors, it ran very rich and rough idle, but it pulled hard
Then i put back 1.8 injectors and motor idle perfect, but it not so powerfull like 2.2 shuold be.

It's similar but not the same
nope. a little different. but quite similar in some respects
I have a 96 obs that had a 1.8 in it when I bought it early this year-- it should have had a 2.2 I changed it back so that it could pass smog. All the plugs matched really the engine belongs in that car. The only difference is that the engine I got was a single exhaust port head out of a legacy gt and I had to change the header out as well.
then recently I swapped a 97 2.5 Dohc to a 99 2.5 SOHC (it's a total mother fu--er of a swap) I'm still working out some little bugs but it is running strong. I had to remove the intake manifolds swap out the engine harnesses, frankenstein the intake manifolds to accommodate the IACV and EGR system, change the TB's and block off the sohc's idle air circuit, and fabricate the EGR system plumbing to name but just a few things that were needed.
I don't have any direct experience with a true 1.8 obd I > 2.2 obd II Just 1.8 OBDI in a 2.2 obdII car .... now that ran like crap.
