Loyale 2.7 Turbo Posted January 24, 2009 Share Posted January 24, 2009 You`ll Need an EA81T Engine! ... is Better to Swap the Entire Engine for Sure. Better than that, you can Swap an EJ Engine there too ... ... Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted January 24, 2009 Share Posted January 24, 2009 The EA81 and EA81T heads are completely different. The engines themselfs are different. EA81's are carburated EA81T's are MPFI There is a computer that controls the EA81T. Each head has fuel injection ports. The pistons are different to lower compression ratio. If you wanted to cheat, you could do a SPFI conversion and bolt on a Turbo. But the ECU that runs a SPFI may not operate correctly if intake manifold pressure goes into the positive.
