ea81 to ea81t


Recommended Posts

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.
