Borg Warner s259 question

[xezerax]

Ok so I am playing on upgrading from my td05 pte5557 this winter and I pretty much have my mind set on the s259 extended tip. My plan was to switch over to a t3 setup and I already have a manifold/ 4bolt o2 housing picked out for the setup.

But when looking at the different turbine housings I noticed their "4 bolt" outlet is a .55 a/r, the same as their td05 housing. Am I going to benefit much from switching to a t3 setup when I could have a .55 a/r td05 housing and keep my current manifold?

Or should I just go for the .70 a/r v-band outlet and worry about fabbing up an o2 housing when the time comes?

My plans are to make at least 500whp with meth and race fuel if I have to, and low to mid 11's

Heres the info on the turbo..

If you're using a T3 flange you won't want anything but the .70 a/r V-band housing to support proper turbine flow.

I'm not saying the .55 housing isn't capable....Wendy's car made almost 550whp with the S259 in a .55 DSM bolt-on turbine housing.
