Okay... So I have a set of 1600cc injectors on the way, and I am working on a Turbo now.

I've been offered a decent deal on a Borg Warner S475. It has a T6 Flange, a 75mm Inducer and flows 110lbs/min. I'm looking to make around 700hp on a B series and was wondering if anyone had an experience with turbo like this.

I believe this is Borg Warners answer to a GT42 turbo..

 

The borg warner turbo's are non ball bearing correct? What would the lag between shifts be like.

 

this is a great turbo and is more then you will need for your 750hp goal. i would look into the s471 with the .80 a/r turbine housing machined down to the t4 flange. the s465ti is good for 90lbs and is also really sick

the other thing you will need to look into is that the s4xx series has 3 different turbine wheels.

 

I can get the s475 for $250 cheaper than the s471. Yeah, I know it is a little big. Too bad my GT4088 is just a little small for my 750 goal.

 

marc theres a guy locally here that put down 800whp on a 4088 and in order to be legal in hot rod class you need a t4 frame turbo
