2.5 swap

Featured Replies

1996 Leg outback Wagon Body 2.5, can i put a 1998 2.5 engine in it from a outback? ,will it swap right in? from a wagon also 

HI,

Please remember to Search, as this is one of the most covered swaps for Subarus - right after the 2.5 to 2.2 swap. :-)

 

yes, this will work. You may have some small differences w/the vacuum lines - the '98 had the Charcoal canister back by the rear of the wagon - the '96 is pass. front under the hood. Also, there may be a wire to the P/S pump sensor on the '98 that won't be there on the '96.

 

Good news is that the '98 has more HP/Torque than the '96 AND it can run on Regular.

 

Remember! Do the Head Gasket/ HG BEFORE you install any EJ25/2.5 engine (2.2 is recommended, too,). Unless you have documented proof they've been done.

You can just use the intake from the 96 and everything will be exactly the same

After the swap you'll need to buy plug wires for a 97 outback or legacy gt for them to fit properly.

will the bolt patterns line up for the tranny?

Some engines have 4 bolt holes and some have 8 though I'm pretty sure

Still mate up and hold fine. Just an fyi

Works just fine, I've done phase 1 (4 bolt) engine with phase 2 (8 bolt) trans and vice versa a dozen times. As long as the electronics are compatible it doesn't make any difference.

In your experience, when doing that, what do you do when there's only 1 hole for the starter? Just use one bolt to hold it in?

I've not had any issue using just one bolt, if you wanted you could drill out the bottom bolt hole on the starter and tap threads into the transmission case.
