U r talking about 3 different types of TD04HL turbine housings, not turbine wheels. TD04HL turbine wheels r always the same diameter, inducer/exducer 52/45.6mm. HL designates size of the turbine wheel and proper housing. TD04HL-nn designates size (13-20) of the compressor housing and comp.wheel / impeller. Last marking, in this case T, designates the profile of the compressor wheel / impeller blades. T is the most "aggressive" profile. #7 housing (7cm2) has A/R = 0.49.

Awesome information & tutorial

The angle flange one can be cut off a a V band welded on. Makes it easier to install then. Do one from the T3 range from the early 760 and 740 turbos next!

Unfortunately, I don’t have those turbos on the shelf to compare them! And truthfully, I don’t know much about the T3 range turbos.

Why V-band for the downpipe conn. to turbo?. Why extra costs, unless one can weld the V-band by himself?. Why take a risk of leak of exhaust gasses + possible fire hazard (jetflame / blowpipe), due the poor welding?. 🤔 Cast iron + stainless steel is not a good combo ... imo. I tack-welded mine 3" full stainless steel exhaust system components with a MIG + stainless wire. 😇 A pro then welded seams gastight with a TIG w root gas. Yup ... cost mee a lot of money, but it was and it is worth every cent. It flows (minimum backpressure) and it sounds awesome w all the typical Volvo burbing ... like B5244T should sound. 🤣
