99 SOHC 2.5 Swap Questions

[lmdew]

I couldn't pass it up there was a 99 Forster that was hit hard in the side. 140K on the car and the engine checked out so I grabbed it. As I pulled it I noticed it had only 2 connectors on the engine harness so:

 

Will a 96-99 2.5 DOHC manifold bolt up so I have the correct harness on the manifold?

 

It does have the port in the head for the EGR so that should not be a problem.

 

It's a dual port exhaust, it also had the oil filter cooler.

 

It was nice of Subaru to put another engine to trans mounting bolt under the starter???

 

Thanks for you knowledge, Larry

you can't (easily) swap SOHC and DOHC engines.

the plug behind the starter is to access the pin that secures the throwout fork, since the throwout bearing is snapped into the pp, and this has to come out to remove the fork fro the bearing.(hydraulic clutch)

 

you can get around this by removing the pressure plate bolts from the gap in the bellhousing to remove the engine, but you still will have to remove the fork to assemble the clutch to the flywheel before re-insall(using the same trans)

 

itherwise the clutch disc is the same with cable clutch

Just to be clear, are you talking about just the Intake Manifold (IM) vs. the heads?

 

DOHC IM won't work on SOHC heads, but you could put '96-99 heads DOHC heads on '99, which is what the '99 OB/GT are (Phase 2 block w/the Phase 1 DOHC heads). Use the heads, IM and harness and go....I think...I'm still unclear on the compatibility of Crank Sensor (and possibly a couple of others) from the Phase 2 EJ25 blocks.

 

Search on here as it's been covered.

Dohc intake won't bolt onto sohc heads.

You are thinking of a turbo clutch. This is not.

No just snagged the motor because for $200 you can't pass them up when you find a good one.

 

I'll hang on to it until I find a Subaru that needs the SOHC engine.
