First off- please forgive me if this has been asked before. I'm still kinda new to turbos and therefore I might ask a few stupid question:P

I own a 98 s70 t5(auto) as of recently my turbo has started to leak oil and is losing boost. I'd rather upgrade than have the turbo rebuilt. my plan is to upgrade to an 18t but I'm confused as to what parts I would need to complete the install aside from the turbo itself and what other supporting mods would be required to make everything run good.

Since my car is already turbocharged would i just need the turbo itself? would my current components fit onto the 18t?

Is it 100% necessary to have my ecu remapped? if so what are my best choices for someone on a moderate budget?

thanks for your time everyone, have a nice day.

IPD should have everything you need. look at the stage 3. don't like their prices, piece it together yourself, but you will need their tune.
