Downgrade from 4EFTE to 4EFE

[homeboy]

I believe this is possible because the engines are identical at cams etc. What other parts are needed besides the ECU, injectors, exhaust, loom modification (to fit the new ECU)?
And how about the compression? Am i going to need a thinner head gasket to raise the compression? Or the car will run OK with a compression of 8.2:1?
To be precise, I want to go to 89661-10240 ECU, what parts am I missing that i need?

The pistons on the turbo engine are different they have lower copression pistons using a thinner head gasket will bearly make much of a difference.
You can pick up a 4efe engine for about £200,
I think you may have to change the engine bay loom, dash loom and ecu.
