Just a few little bits to add.

The gt2560 is a water cooled turbo which will add heat into the cooling system. We've tried to compensate for this in three ways:
- Fitting a 197 thrermostat which opens at a lower 75 degrees
- Clocking the turbo. The clocking is to better aid the natural convection current created in the cooling system when the engine is switched off as explained HERE. Whilst we weren't able to achieve 20 degrees on the stand, because of the engines natural tilt back we are very close. You can see the mark on the turbine housing which is 20 degrees. We did slightly rotate the turbo back from here to access one of the turbine housing bolts.
- Fitting the biggest rad possible. The cup Direnza rad is marginally bigger than the non-cup version and about 50% bigger than a standard one.

As you've also seen in previous posts we've done a fair bit of wiring work. This involved tidying up the cut off switch area a bit to keep it on theme with the more OEM original interior. We've replaced what was a hanging out fuse holder with a radio blank and durite panel fuse holder. This allows the central locking to work but any greater power draw to blow the fuse. This means we've finally been able to get power back in the car and test a good portion of the SMDs we changed over. Touch wood they're all working and look brilliant. Now the car has an OEM set of ECUs a bit of playing is required on CLIP to turn off the ESP and airbag lights.

This build uses an AEM FIC 8 30-1930. The only benefit over the FIC 6 is the electronic boost control controlled via an 3 way mac valve. Whilst you could run a separate boost controller, having the boost control referencing live ECU data is far superior. As the car has previously had an OMEX standalone ECU quite a bit of wiring was required on the ecu plug to reattach the OEM wires and splice in the AEM. The AEM was previously fitted to a V8 AMG which used a fair amount more wiring than the Clio whereas now we're only using 15 pins. Although I don't have any pics to hand, after much searching, we've gone for a Delphi bulkhead grommet which which allows a fair amount of wire for the piggyback to pass through the firewall without risking leaks, keeping it OEM and insulating the cabin from noise.

As Mart said, we've got a few things left to do on the car but we've also made huge progress over the past few weeks, have worked late a few nights after work and it's very satisfying to see the end in sight. When the bodies were fitted the person who did it wasn't exactly proud of their work, chopping a few wires mid loom and not protecting the ends. We now need to correct this hence the large wiring list below!
The main things left to do are:
- Fuel pump
- Wire back in: map sensor, carbon canister resistor, throttle body plug, shift light, fan,
- Tidy up a few interior bits
- Boost solenoid (wiring, hoses and bracket
- Relocate clutch cable
- Turbo oil feed/drain
- Turbo coolant lines
- Intercooler piping
- Relocate oil cooler
- Secure exhaust
- Reassemble front suspension
Here's a pic of the clutch cable how it currently sits.

Other than that, door cards are now in and the car has Cup front glass. We are still trying to make videos but the reality of this build is that we now want it finished and with the year evaporating and life calling we're all about getting the car done now, fitting in filming when possible instead of it being a priority. That said, there should still be some good content at the end
