It's as safe as...

- Tuning of fuel, ignition timing and MIVEC at your new load levels.
- The mechanical workmanship involved in doing the swap sensibly.
- The quality of the TD05 you'll be using.
- Whether you have binned the tiny Ralliart intercooler, in favour of a decent one.


My Ralliart has had an Evo X TD05 on it for about 3 months now. I've kept boost levels quite mild - about 21psi peak, tapering to 16psi at redline - because I'm naturally cautious.

I've found the boost control a bit more wobbly on the new t/c than with the old TD04... and that's with a 3-port.

Manifold air temp is quite a bit lower now at full boost, compared to the overworked TD04 turbo... so the car feels less stressed overall. But, again, I'm not pushing it hard.


Good luck!

Looking to get Adam (beeble) to tune it. I have an installer in mind also which has done a few of these already. Turbo will have around 2,000km taken off a reasonably new car.

Hope all goes well. Will ask for a very conservative tune thanks for the advice.

Oh and I've got an Evo X intercooler
