prezton Posted November 15, 2021 Share Posted November 15, 2021 The scrapyard I work at has a '14 wrx that came in, with engine and transmission at about 110k. I purchased my '09 for about 5k last year, and long story short. The engine and trans are no good . My question is, will the '14 wrx motor and trans fit in the 09 legacy GT? If so, what changes would I have to make? I did do some digging at the scrapyard and only saw that the engines have different fuel injection. (I think the WRX has spray.) Thanks!

Pleides Posted November 16, 2021 Share Posted November 16, 2021 Aren't new(er) WRXs cable operated trannys? Not sure about the engine and ECU compatibility. 14 WRX still uses an EJ and 5-speed. Link to comment Share on other sites More sharing options...

The motor should, for sure, fit into an LGT. Take the intake manifold and all that jazz out of the WRX as well. You'll get topfeed injectors along with the ability to remove the TGVs and all that during the swap to the manifold from the WRX. The trans I'm fairly certain is a bolt-up affair but your speedometer on the Legacy gets its information from a different location than the WRX (you'll wanna look that up - I'm pretty sure it's fine for the LGT->WRX 5-speed swap but not the other way around), the rear diff is different, so you'd need to swap the rear diff and make sure your final drive ratios work, and I'm not 100% on the axles working.

darthqwo Posted November 16, 2021 Share Posted November 16, 2021 (edited) always useful to upgrade to parts half decade newer; swap should mostly work, but you might need to retain the lgt engine harness and lgt ecu--need to see fsm wiring section to see if not else, as t guaranteed remainder of bulkhead is completely different betweens legs and imps other things useful to possibly retain is maf sens and o2 sens--need to see romraider def to see if scalings are same else the wheel speed sensors are same on legs and imps and attaches to bulkhead on fraem rails by firewall; if ur talking bout engine speed sensor that i wouldn't be sure of since internal to mt Edited November 16, 2021 by darthqwo Link to comment Share on other sites More sharing options...

Max Capacity Posted November 18, 2021 Share Posted November 18, 2021 Wouldn't the easy way to go is bolt your intake system on the EJ out of the WRX. The ej255/257 is the same block. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.
