What do I need to upgrade on my 87 b230ft for a turbo upgrade. And what turbo should I upgrade to for 250-300 hp. Thanks.

It would probably help if you add details on what research you have done so far - there are many builds on here to reference, for example...
stavtech said:[J]ust like the OEM Subaru, Saab, and Volvo turbos, the HE221W is actually a Mitsubishi TD04 based unit, but the Holset version is far better than all of them, it's like a 'Super' TD04.
...
[T]he HE221W turbine wheel is actually the same overall diameter (but a better flowing design) as the 'big' TD04HL turbine wheel as fitted to the TD04HL-15T on the Saab 9-3/9-5 Aero high performance B235R engines, the TD04HL-13T on the 2.4T 5cyl Volvo engines from the C/S/V70 and similar engines, the TD04HL-15G on the 2.3T fitted to the high performance versions of the Volvo 850, and in fact many older Volvos such as certain 940 turbos with TD04HL turbos
...
So yes, as you've probably guessed already, you can simply swap the turbine housing over from your TD04HL, on to the HE221W, it's just one clamp, super easy, and hey presto, you have a turbo proven capable of up to 380bhp, 3bar boost, mega spool, that fits to the stock exhaust manifold and downpipe, for very little money
The turbo.What do I need to upgrade on my 87 b230ft for a turbo upgrade.
A bigger one.And what turbo should I upgrade to
BHP? WHP?for 250-300 hp.
Also this before blowing it up by making all the boost.what transmission are you running?
Just search there is a ton on this
I suspect the OP has been scared off.
