SPFI conversion

Featured Replies

For past few days I have been reading up both write ups on conversion. Today, I went to u-pull yard and pulled entire wiring harness from ECM all the way to the head light. That includes two relays and 4 relay banks, fuse panel and so on. I did not sever any wiring. I left all the wiring harness under dash panel alone. Pulled intake manifold assembly and all stuff that is attached to intake manifold. I pulled entire fuel pump and bracket and hoses.

 

Is that all that I need to pull?

 

Oh by the way my car is 1987 Wagon GL converted to 5 speed dual range from 3 speed auto. It has factory a/c and cruise control. It had carb but Im pretty sure its not california but it has wiring to the carb itself. The donor car is 1988 legacy with 5 speed and no automatic seat belt and it does not have a/c. ECM is black color. All subarus in the yard has exhaust pipe cut off right at the head and removed the center portion (cat?). :-\ Where do I install O2 sensor on and where do I get the bung to weld on?

 

When I got home I started on my car and noticed that my car has more devices than the donor car so I will need assistance in determining what stays and what goes into the trash. I'll be sending up photos.

 

thanks.

You also need distributor and coil, and MAF sensor/air box assembly

Yes got them.

 

Problem 1 is that my wagon has grape fruit sized vacuum reservior. Donor car does not. Is this part of cruise control? It is mounted on passenger side of fender above the axle.

 

Problem 2, there are round plastic canister located on rear side of the pass side cylinder head. it was connected to egr valve and to air intake and to pass side exhaust manifold or exhaust side of head. Donor car does not have them.

 

Problem 3. there are sqaure plastic canister on drivers side of the cylinder head right by the disty. It is connected also to drivers side exhaust manifold/or to exhaust side of the head. It is connected to the air filter. Donor car does not have it either.

 

What to do with them? Thanks. I have photos but I can't upload it for some reason.

This is my car looking at passenger side fender. Do you see a grapefuit sided black ball? What is that for? Also there is a electrical vacuum valve above that ball (little to the right) - what that is for?

 

Anything do you see that needs to be removed?

After reading 1987 FSM. I think I got air injection system if I am not mistaken. Those two black canisters on both sides of engine are silencers, correct? If so, what do I need to do to remove this completely? Crimp the steel pipes that leads out of the exhaust side of the heads - will that work? Any ideas?

 

 

That big round sphere tank and other stuff I believe its cruise control and I have not confirmed it yet so I'll leave it alone as I do want cruise control feature.

 

thanks

Yes, cut and crimp or weld. Or remove them where they bolt onto the head and make block off plates out of 1/8inch steel.

Yes those are for the cruise control. IMO that that is the *dealer installed* cruise system, not the factory type shown in the FSMs.

 

If you don't need/want/use you're cruise control, I would be happy to take those parts off your hands.
