i was thinking of doing the same

i hadn't thought about the water lines though, good point, there is a place to get the oil supply to turbo?

i would also think you need the DET sump to drain the oil back in from the turbo

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

thinking about doing a de+t on my already ca18de wagon and was wondering what i would need to do. i know i will need a decompression plate and the turbo and manifold and a micro tech or det computer. is there anything else. how different
are the de and det blocks and internals etc.
