"Btw could you do a compression test without a key ??"

Well, I guess you could insert a lever into the crank pulley and twist it really hard (and fast).

Never heard of compression test without cranking engine over (with starter). Leak-down, yes. Comp test, no.

Couldn't you do it using the starter wire ??
I just forgot to drop my car key off and they said they did the compression test so I was little iffy

Doesn't your key have an immobilizer chip in it? Not sure if you can bypass it, to crank engine...

Couna777

It's 03 idk if they do
Even they do I don't have stock ecu so ..won't help?
Aem v2 supports immbolization ??

Nominal compression should be (metric) 2,570 kPa or 16.0 kgf/cm^2 or 228 psi.

Don't see 120 in there anywhere. But I don't take Japanese cars to Russians. They control the computer market, of course...

Regardless of compression numbers, if they said they're all the same that's probably not the issue. I'm going with spun or seized bearing. Sorry but you'd probably be looking at a new motor. I'd suggest having an oil pressure gauge if you plan to turbo again. You would've seen pressure dip and known to pull over. Good luck though and I hope I'm wrong!

If it's seized it won't start at all right ??

windhund116

If the engine seized it may turn over very slowly or not at all. It prolly will not start up.

Couna777

So I guess my motor is not siezed since I could star back up
The next day of the incident I could start back up but it stalled in few min .. Seems like it stalls when it gets hot and it starts up again when it's cold

No, sounds like it seized up, at temp. When engine cools down, the tolerance between piston and cylinder increases just enough so that the engine will start & run. Then, when the engine warms up, the pistons tighten up in cylinders and engine dies.

You are going to have to pull head and inspect. Sorry...
