Default Borg Warner S256 and S362 Turbos

I currently have a stock mount GT30R kit with a .63 in my 2.0L Subaru WRX 02, But I will be puting in a S2 2.5L crawford shortblock soon with STI Type C heads .. I am looking for more power that the GT30R can produce with the same spool characteristic as the GT30R turbo on my new 2.5L S2 block....
I was looking to get a GT35R .82 in till I came across a post in Supraforums about Borg Warner turbos and became really intrested in the Schwitzer/Borg Warner S362 turbocharger, with its Extended Tip Technology.

This turbo has the 62mm inducer which is rated at 65 lbs/min, this turbo is designed to work efficiently between 500-650whp. with better spool than the GT35R turbo....

Just an FYI folks-

TEC - www.turboengineering.com

http://www.turboengineering.com/cust...ies/ht300.html

Has been dealing with Borg-Warner/Schwitzer for the past 3 years or since I have know him. I know a couple of people who have the HT series turbos on their STi blocks up here at high altitude and they perform VERY well. They are right there with the GT35R series turbos but are better IMHO given their wider efficiency islands and higher PRs. From my recollection they usually edge out the GT35R setups up here on pump gas.

I know one person up here with a street trim STi running I believe a HT200 @ 20-22psi (spring pressure with EWG setup) broke into the high 11s on pump gas up here at 5800ft asl!! The person isn't even that big of a drag racer either!! Xephyr runs one of these turbos as well. Super Rupair sells them still I believe and Harvey (the tuner) there could give more details on the power they make in his experience. I am only going off of second hand information on the power they have made from what he was told me.

If I were to go rotated mount this is the turbo series I would go with from what I have seen.

Default S200 Turbo

According to TPS is a perfect fit ,when you order this turbo with the correct exhaust housing for your application.. In my case I will have to order the t3 five bolt exhaust housing .... BW recommended a .55 AR exhaust housing with the S256 do to the long manifold runner we have in our cars and the cold temperature of the exhaust gasses in our cars..

My compressor cover in my GT30R is 7.1/4 inches and the S256 is 7.1/2 inches ..... Not much off a difference between the two...
I will provably will order my turbo in a few weeks , I am giving time to see how the stainless steel hold up compare to cast Iron in the exhaust housing.... I

so as long as I get the S256/ S258 in a t3 trim with 4 bolt exhaust housing , it should bolt up to the perrin piping kit ( uppipe & down pipe) ?

Is the borg warner a 3" 4 bolt? Perrin uses a 2.5" 4 bolt on their DP.

It is the 2.5" bolt pattern. Just like Perrin uses.

So the S200 is basically like a GT30R?? If so, the .63ar on the GT30R is to small and causes to much back pressure. So why would going with an even smaller ar on the S200 work??

totally useless info. The S200 makes 10-15whp more than the GT30R at 1psi more boost.

I agree Tim. I see no advantage over the 30R.

I'm not knocking on you or trying to create a pissing match. I'm just looking at the data provided in the multiple links in this thread and I'm not seeing an advantage. The only difference I saw was the S200 came up to 21psi 300RPM prior to the GT30R.

But! If you know how Mustang Dyno's and Suby's get along (like I do), you'll know that they probably used dyno roll speed to get an RPM pickup, which makes comparisons based on RPM almost impossible unless you know the exact roll RPM to vehicle RPM calibration # and use it for both runs, which most tuners don't.
