[volvo B230ET]

Im half way through the restoration research and i have hit a snag in terms of what turbo to use.

I have got two turbos that both came from a B230ET,

TB03 1987 Exh:48 Com:52

TB0363 1988 or 89 Exh:48 Com:42


Does anyone know anything about these or your opinion on which one to use.

Thanks
