pfft, decomp plate....that just kills all the fun

stock DET parts you need:
Turbo + Manifold
turbo oil line and 90 degree adaptor for the block
Injectors
ECU
Loom, or wire the resistor pack into existing loom and change injector plugs
thats about all i can think of now, all the important sensors seem to be the same, temp sender is a different colour but dont know if it sends a different signal or not

You will need to make up the water lines to the turbo as the DE block doesnt have the hole tapped into the block to suit the stock lines
Then there is the obvious cooler and piping, exhaust ect

No need for a decomp plate if you are just running stock boost, mine was running 7psi. all the decomp plate will do is make it a lower performing engine and less fun to drive

internals are the same, det has oil squirters and 8.5:1 comp pistons compared to the DE 9.5
The block is just missing the tapped hole for one of the water lines to the turbo, and a couple of the hoses on the engine are a little different to suit the turbo water lines
