Paul..... I talked to my associate . Here is the response.........A   TO4E44

turbo compressor trim 57, AR 60 , Flowrate 50, Max. flow 50, Turbine wheel
76
,  housing  AR   84 .   It will have a divided inlet and a clamped outlet.

That will cost approx 704$    For another 175 we can put in a one piece
journal bearing , non rotating with a 360 degree thrust bearing assembly.
 We
will also put in a double wrap sealing ring as opposed to a gapped sealing

ring . I would highly recommend the bearing upgrade for a VERY low turbo

failure rate. Hope this can help you. Please keep in mind that ANY turbo
can be modified !! JIM DANA



Sounds good. I assume the divided inlet is a dual scroll. I am not
familiar with the term "divided inlet". Do you have a picture?
I don't think we need a dual scroll.


I think he means alike the standard mazda, has a divided inlet, to direct gas
to different parts o f/angles at the turbine wheel

Also what is "clamped outlet"?

I hope its not the rather didgy looking clamped on exhaust that I see on to4
etc on street rotaries in Australia, they heat up the exhaust and slide it over
the turbine outlet and then do up a big hose clamp on it, ...


We also need Inconel wheels. Sorry I forgot to mention that.
How much for that option?


How about ball bearing option, surely that is worth the extra few bucks?



I also assume this is not a water cooled housing. I am sure the oil does a
lot of
cooling so it may not be necessary but since we have a liquid cooling system
it might be nice to have a liquid cooled turbo charger.


Agreed wholeheartedly
