As said, the 18g and 20g turbos are the same... except... the 20g has a bigger compressor wheel to shift more lbs of air.
You should gain anywhere between 20-40bhp over the 18g (everything else being equal). And what with its billet comp wheel, then there will hardly be any spool loss compared to the 18g, either.
And without doubt, you're getting the better deal! Brand new, the SC40 is £950 +VAT!

Does the SC40 have the 33% lighter billet comp wheel - can't remember?

And without doubt, you're getting the better deal! Brand new, the SC40 is just over a grand IIRC.

440 is prob asking a bit too much, but each car/set-up is unique, and nothing is absolute/for certain.

Typically, the mean bracket for 20g's is 370-400 on V-P (on a 2.0L).
But the Billet range are good performers, so hopefully it'd make near the higher end of that bracket.

If its anything like the one I was looking at on here before its a Blouch SC40 20G.
I emailed Kev at SC to ask him this week about them, he said:
Hi,
the standard 20 G ( sc40 ) is still a great turbo, 400 BHP capable.
I have attached a small write up regarding tuning the sti, worth a read
cheers

Blouch Dominator is Dominator nothing more,nothing less,difference is between the R(non billet version of Dominator) and XT-R(Billet version of Dom)
Blouch turbos are here Scoobyclinic and Scoobyclinic is probably only one seller of Blouch in EU...

Honest answer don't know,on 2.5L you will be OK with 8CM or even 10CM,as i said few times before with 8CM you will not loose spool so much(against 7CM),but with 10CM you loose spool,but you will gain on Top end.

How to say,i was sold mine Dom 3.0XT-R due have 10CM exhaust housing,this turbo will make full boost on 2.1 with AVCS around 4200-4400RPM what i know and what i ask few people on Nasioc,this turbo is best for 2.35L or 2.5L..

A 2.5's extra 500cc will be able to easily drive an 8cm housing (therefore not suffer slow spool), so if you were to fit it, you'll gain some extra bhp over the 7cm.
Conversely, you can fit the 7cm to a 2.5 to have an ultra early-spooling motor (but won't be able to make as much power as the 8cm.)

On 2.5L you should be all right like 8CM or even 10CM,if you are looking at Nasioc and other US sites you will see mostly guys there don't running AVCS and still making reasonably good boost at nice RPM with 8CM/10CM..

On your 2.1 with 20% meth + V-P, then I reckon you'll get at least 420. But you 'should' get nearer 440+, as you said.
Just keep your 18g to one side until after the mapping though (just in case that SC40 don't make the numbers!)...
