Not sure which one..? there are three possible parts for your car, the description is somewhat ambiguous: "99 Legacy GT" is an EJ25D which has two drivers side cam sprockets. you need both or intake or exhaust? "the left side" suggests you only have one - which could mean it's a 99 Legacy (not GT) which are Phase II EJ22's, or a swapped GT with a Phase I EJ22 (a very common swap) if it's a Phase II there are also sometimes two different trigger marks on the crank and cam sprocket

I don't have the old engine any more.

here is a pic of the engine, it was a wrx, has all wrx parts just a different engine. We used the harness from the 99.

It is not a turbo, I think it was a junk yard motor put into a wrx.

What is a clutch switch circuit?

It came from a 02 wrx

I have a automatic 99 subaru legacy and last year the timing belt pulley broke. I found a motor to put in it which I got from a 5 speed wrx It is a ej25 motor, when I got the wrx it started up with no problem. We put the wrx motor into my subaru...and nothing..It was turning over but would not spark...Since it came from a 5 speed we unplugged the cam sensor, still nothing. We put a brand new coil pack in, still nothing. It wasn't getting fuel until we replaced the timing relay plug. It gets fuel now...but still no spark. I have talked to countless mechanics and no one knows for sure what it is, some tells me it is the computer but others tell me it isn't. Any idea what could be causing this?
