Make sure it's been converted to front entry and that it has the water and oil return pipes, new gaskets for up-pipe and downpipe, then simply swap the turbo.
You'll need to use a Dawes to control boost afterwards unless you're also planning a remap (best approach). If fitting the Dawes, you should also monitor boost/knock/mixture at high revs - I doubt you'll be able to run much more than 1 bar at 6k onwards without running lean at some point.

RR my bugeye has a TD05 16g fitted I had no problems or issues with it other than you will have to drive it off boost until you get it remapped.

Not much choice I'm afraid, the TD05 flows so much more air than the TD04 it replaces that the ECU map can't cope on boost. Too much air and not enough fuel = very lean.
Off boost the car's running open loop using the lambda which isn't a problem. You could always "disable" the TD05 .........which I think you can do by removing the actuator arm but I may be wrong and I'm sure someone will correct me soon !!

This messes my plans up a little.
Could i not reduce boost temorarily using the MBC
Im sure i know someone running a TD05 withough map on WRX, or is it just a matter of time for hime then.?

See dowser's comment above, he might be running electric / mechanical boost controller to keep a lid on the boost. The ECU should be able to cope with the slight increase in boost by altering the map to suit.
A straight swap TD04 to TD05 without remapping or boost control would be somewhat fraught !!

If you can monitor knock and afr, you could disconnect (at the BCS end) the pipes to the actuator and turbo nipple, then connect the 2 together. This will limit boost to 0.7 bar, but it would be foolish to use boost without monitoring AFR's and knock.
Another thing you could do if you have an adjustable fuel reg is to raise the fuel pressure a bit, closed loop it would still run stoich but open loop it will run richer (safer). Again using your AFR's to set it temporarly.

Yes, air / fuel ratio. I find it handy as a guide rather than for absolute readings.
The OE lambda sensor isn't the best for absolute readings on boost, but whatever reading it does give for the car in its current form, it can then be used as a rough setting to aim for when the mods go on.
Only as a temporary measure though! Then once the car is mapped then whatever reading the AFR is on boost is the reference to check to every now and then. Other than that it doubles as a lambda sensor checker

Paul (Rice Rocket),
Do you need some 550's to go with the TD05? I bought some second hand ones, which I am not sure I am going to use. If you want to buy them the next time you are in Dubai you are welcome to them!

If I read right from Midlife's comment about removing the actuator arm. I believe this controls the wastegate which would PREVENT excess boost so if disconnected who knows what boost you would get.

If you disconnect the actuator arm, you will get NO boost due to all the gasses passing throught the wastegate, and not the turbine housing......
As i understand it anyway....

Thanks Ron
I thought there was a way of getting zero bost
Jay m a ....as an aside I thought the newage Wideband Lambda sensor was much better than the narrowband stock item on the clssic
