IHI48 turbo for stock internals B230

I'm swapping a B230 with IPD turbo cam, stock bottom end, Speeduino ECU into an 1800ES, and was traded an brand new IHI48 turbo from a WRX.

I'm only looking for about 250 hp, so is this turbo too big for a relatively stock B230 ?

Would there be a lot of turbo lag?

* Yes, I know it's a weird Subaru flange, but I have to make a custom manifold anyways.
