Tuning part possibilities?

[Keno]

I've just gotten my first request to up the performance of a client's car by 6-11%. I was like, cool, so I'll just plop on a turbo for 7% and done, since apparently I can only change the software of my own cars and not a client's.

But it won't just let me bolt on a turbo so I was wondering, is it even possble to add a turbo to a naturally aspirated engine? And if so, do I need to accomodate other parts to fit the turbo, like exhausts and manifolds and such? Do I need to go further and change the engine head too? Or am I limited to changing the parts that can normally be found on the car?

Specifically, I have a Sakura Yaro in the shop with a naturally aspirated I3 engine.

Thanks in advance. :)

No you can't. If the engine is NA, you need to install parts corresponding to the engine. If you want a turbo on one of your car, you have to swap your engine with the turbo version.

There is the "I3 DOHC Turbo" in game,
but client won't be happy if you swap the entire engine (?)

Just install a perf gearbox flywheel and disc, you already got 5% then try other parts like exhaust ...

Aha, cool. Thanks for clearing that up. :)
