   Can this 9 blade be ordered to simply swap into a Sonata 2.0T that is equipped with the TDO4HL4S19T ? Will it balance with the existing stock compressor. If so what is the cost….

      Yes it is a direct fit, It can be balanced with the compressor wheel. We do have a balancer also, if you need that service.

      The Subaru 13t came as a tdo4L 41mm, the tdo4HL will fit with machining the turbine housing which we do. The 9 blade tdo4HL is a direct swap for the tdo4HL Turbine.

         Love your videos man. Can you tell me how much of a gap do you make on turbine side? I’m doing 0,6mm on compressor side, but this time I’m machining turbine side from L to HL (Td04) and I don’t know how much spece for exhaust gases should I leave. Originally on my turbo there was 2mm on inducer and 0,9mm exducer diameter gap. Isn’t it to much? Please let me know what you think about that.

            The compressor side, i aim for .7mm larger than the compressor wheel for tdo4. the exhaust side i aim for .8 mm larger (tdo4hl is 45.6 + .8 = 46.4.

      We don’t have Renaults in our country so finding that turbine housing in my country would be a challenge. I can machine your turbine housing though.

   How does the mass of the 9 blade TD04HL compare against the standard TD04L wheel found in WRX applications? Better yet, what is the mass of the latter?

   Can you comment on the boost threshold and response between the two wheels?

   Also interested in mass differences between a standard 13T compressor and a billet 15T or 19T wheel. Can’t seem to find how much a 13T wheel weighs. I acknowledge that the bigger wheels should keep the turbos running at higher RPM but would like to know if these specific aftermarket wheels (eg. TD04HL-19T) are lighter than the standard TD04L-13T wheels to aid in spool up and transient response.

      TD04 = ex 40.0mm, in 47.0mm
      TD04L = ex 41.3mm, in 47.0mm
      TD04H = ex 44.2mm, in 52.0mm
      TD04HL = ex 45.6mm, in 52.0mm

      For a 2.0 application, we build them with the 50mm x 61 x 62 billet wheel and tdo4HL at minimum. there is also a 52.6 x 68 billet wheel for this application. You dont have to worry about spool up on that small of a turbo, if you did a tune upgrade it will help a lot with spool up too, sometimes the subarus had an up pipe leaking problem that would affect spool too.

      If you wanted a step up, we could build you a 16g (48.3mm x 68mm compressor and 49 x 56mm turbine (9 or 12 blade)
