Convert 2.5l to turbo?

[nItpIk]

Anyone have experience with this? Is it relatively easy, or can it even be
done? What's involved? Is it a matter of just changing / adding parts?

Thanks

You can do some reading in the technical forums at www.nasioc.com
especially the Conversions and Aftermarket Forced Induction forums.
In short though, aftermarket turbocharging of the 2.5 normally
aspirated engines is generally not the best idea, durability tends to
be poor and you wouldn't want to run more than moderate boost of
around 5-7 psi. It's also a good amount of work to do it properly.
A full engine swap is regarded as the better way to go, complete WRX
and STi engines are readily available on the used market. Such a swap
is also a lot of work though, particularly with regard to the
electrical work/wiring required. You also need to be aware of the
inspection and emission requirements in your state and county as this
may render a swapped or turbo'd car unable to pass inspection.
You should further consider the fact that a project of this nature
will cost a good amount of money (it's always a lot more than you
initially budget for) and will keep your car off the road for a while.
If you aren't willing or able to take on a project of this nature then
you'd be best off trading or selling your car and getting a factory
turbo to replace it.
