What do you guys think about this a bottom mount borgwarner 7064 internal gated twinscroll setup? Heres the turbo only problem is you can only get the turbine housing in .92 ar so it might have some serious back pressure problems.
Well lets hear your thoughts!

And heres the turbo!

 

Only 52mm inlet, don´t think it´s big enough to cause back pressure with a .92 turbine.
Think you can go smaller on the turbine if you want.

 

Hmnn I would think it would still be a problem, could you please explain for me?

 

Most people on this forum run .63 or .82 turbine housings, I use a .82 on my 66mm (inlet diameter) turbo, 540whp.
Sounds a bit big to use a .92 turbine on a 52mm turbo, you can go down in size to match the inlet better.

These things need to be tested to be sure since it depends on engine type, turbo, fuel type and much more. Decide your power goal and look at other builds around those numbers. Then you steal their turbo spec.
Cool if you buy the BW, think it will work fine on the S.

 

on divided setups, bigger is better in most cases. .92 sounds large but on a divided setup it isnt. but i would go bigger on the cold side. thats very small for our motor that breathes very well.

 

The highest I want to go in power is 500hp, but it might be a better idea to go with a bigger compressor.

 

If u want 500 get a turbo good for 600. Otherwise ur in the top end of the efficiency range of the turbo.

Id get something similar in size to a gt35 at biggest. Maybe a gtx30 would be gangsta for that. Wouldn't need to be divided.

If staying divided go gt35 size at least. 60-63 cold side.

 

TheBoostLab.com owners are personal friends of mine and know their stuff. Whichever turbo you choose, just know they will take care of you

 

that turbo would dominate for a 500hp set up, I have been very impressed by borg warner turbos and can say they out perform garrett
