subaru forester engine and gearbox into 95 legacy

[benniepak]

subject says it all.....just wondering if it can be done and if so what to/not to do when doing it...

spoke with ryan at work but didnt wanna bug him too much bout it

please help if you know anything bout it. ive got everything ready to go in if it can be done

best reply is try it if u have the bits, just take the loom out of the forester and relooom it

You're going to need to re-pin the ecu plugs whether its a 4-plug or 3-plug ECU that you're swapping to (if you're switching to single turbo).

Its not incredibly difficult, just a pain in the ass to do.

Would this be the same with bc5? Drove my auntie's forester and idle was smooth compared to my bc5 which tends to go down then up and even goes right down to 300-500rpm at times....

and since the engine codes are the same are the forester engines closed deck'd as well?

[Koom]

There's closed and open deck EJ20g's afaik.

You can swap the engines but keep the original intake manifold/sensors/ECU etc but that possibly won't do anything to help the idle if it's old sensors thats causing the idle issues.

Thanks for the info koom.

ye it can be done just put a 97 forester in my 94 legacy was not easy as i converted to single turbo rewired the ecu to 3 plug and made anew exhaust systm.

Yeah, theres 3 main types of 20G, the fozzy ones resemble a 20K, but just carry the 20G badge.

Depending on the year foz, it'll be a phase 1 or 2 engine. I think only the SF5A was a phase 1, then they went to the EJ205 V5/6 engine.

The BG5A is a phase 1, meaning you are basically stuck with the SF5A EJ20G and ECU, though it does have a different loom (TT 4-plug, so you need to repin, as koom pointed out)...

You can convert to phase 2, but it's an arse of a job i think, it will be harder than just re-pinning.
