Simple answer no.

You will need to get the turbo electronics.

Series 4 electronics are different from Series 5 so you will need to get a S5 harness.

Also Series 4 engines are mechanical oil metering pumps so you either need to convert usuing a S4 Throttle body or switch the front cover to electrical OMP

Read the FAQ. This has been covered heavily. Sorry to be curt but seriously, this has been covered a million times before. Short answer :: yes it fits. Long answer: there are many caveats. Search for the details, and visit http://www.rotaryresurrection.com and http://www.fc3spro.com for some solid info too.

www.rotaryresurrection.com has a write up on series conversions.

Read that and then read the turbo conversion.

The Series 5 electronics are supposed to be pug and play so you would need S5 electronics.

S5 TII ECU
S5 EFI harness
S5 Fuel Injectors
S5 BAC
S5 AFM
TII atmo/Boost sensor
TII Fuel Pump

Then you can either go...
Keep S4 Throttle body and Mechanical OMP BUT add on the Series 5 Dual TPS(Not sure if it will fit)
OR
Switch front covers so you have a S5 front cover and electronic OMP

Also this is only for swapping the engine. Not including the transmission which will need....
TII Clutch Slave cylinder
TII Tranny
TII Tranny Cross member
TII Drive shaft
TII rearend.

an optional way is use the Mazdatrix hybrid driveshaft and use the TII tranny with your stock NA rearend.(I'll tell ya when I blow mine how long it lasted as a TII)
