I have a 98 s70 glt that i have a 16g turbo for but i was told i need a ecu upgrade to get anything out of it . Can i just use a t5 ecu? And would i need anything else?

turbo, ecu, and fuel injectors.

And the ECU must be from an x70, not an 850, or you will fry the AC portion of the climate control.

Specifically a 1998.

Also, if the turbo is from a 1999-2000, it will work, but you'll have to get the proper flange to put on it to mate to the exhaust manifold.

The one that doesn't say "Aisin-Warner". I can't remember what side of the box it's on.
