Im looking at a b2 s400 turbo, the only issue i am having is getting the american measurements converted to the metric we are all used to talking about. can someone help me out? Im planning on using this as the bottom turbo in a twins setup with my existing hx35. here are the measurements. The main conversion issue i am having is the housing size and I just want verification on the others to make sure I am interpreting the information correctly.
Compressor Wheel Inducer 2.935" Compressor Wheel Exducer 3.944" Turbine Wheel Exducer 3.467" Turbine Wheel Inducer 3.768" Turbine housing ratio 1.32A/R

 

74mm x 101------ Compressor

88 x 95----------- Turbine

 

what about the compressor housing?

 

Near as I can figure it looks like a 33 cm housing, but I'm not positive. I assume you meant turbine housing?

 

you da man mike! do you think this would be a good turbo for towing twins? im looking to push around 450- 500hp when im done. not getting into any pulls or competitions, maybe smoke a ricer or 2 around town. i just want to have the air before fuel because fuel before air gets me very high egts.

 

I'd look to a smaller housing than the 1.32. Thats a lot of exhaust to pass through there to get it going. Maybe something more like a 1.0 or 1.10 A/R. You don't need a huge exhaust housing for 500hp. I'm gonna run a 1.0 A/R on my bottom turbo on my twins, and I'm hoping for a fair bit more than 500 hp.

 

I'm not real well versed with twins as I run a single. On the face of things I would tend to agree with Tate. I would opt for a smaller housing on the primary if given the choice.

 

thats what i was thinking. thanks guys.

 

anyone know where to get a good deal on a smaller b2 or even the housing alone? the turbo i was looking at was $650 but only availible in the one size which is too big. i wouldnt mind buying a different housing and having the bigger one as a spare or if i want to go bigger down the road it will be there. any suggestions?

 

Get an SX S400 or an S366, the standard S400 compressor is 0.63AR and the standard S300 cover is 0.53AR.

 

Is the SX S400 similar to the 'race cover' version I've heard about?

 

any companies someone can reccommend for a cheap b2 turbo?

 

The SX line are T4 foot print, the turbine wheel on the SX line is 74/83mm vs the 88/96mm of the standard T6 S400. The race cover is 0.66AR vs 0.63AR for the standard cover.
