what all do i have to do and what parts will i need to go form a ea81 to ea81t

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 ... ...

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.

wiring harness is different,battery on other side.Radiator is larger,fuel tank,pump and lines are different.

engine and cabin front wiring harnesses are different as well. Some suspension parts too.
