Default Twin Scroll BB Info needed .

Hi all , I'm interested to know more about these IHI TS BB turbos ie VF36/VF38 and whatever comes later . If possible can anone show pics of the housings removed ie the compressor wheels and also that P25 exhaust housing .

I did hear mention of an IHI Vf44 which is supposed to be an STI exclusive , are any of its specs known ?

Cheers and thanks , Adrian .

VF36 Twin Scroll, titanium turbine, large 47.9mm compressor as on 30/34/35 430cfm vf37 is same, not ball bearing

VF38 Twin Scroll, titanium turbine, smaller compressor

VF42 Twin Scroll, larger compressor than vf36, more efficient turbine. Similar in size to VF22

Don't know about the VF44 sorry
