he's not lying about that LOL.... 
Budget Borg Warners
also, would a bigger s series bolt up since it has the same t6 flange and it is slightly smaller in size?
double also, can this unit work with a stock cubed stoick bottom end at about 5psi similarly to a tc76 until it getts a better bottom end? is there a better comparison to the tc76 in terms of power

hrmmm the S400-72
guessin its a 72MM inlet, given i add the t4 turbine housing. how much of a difference is the turbo from an S372 ?? non ETT ? too big of a turbine wheel ?
You don't have any more info on an OLD Schwitzer turbo for me do ya? I know borg warner bought them out so there is a chance you have the specs on it and such. It's a Schwitzer S4A that's been rebuilt and in perfect condition. It's got a ~62mm inducer and i forget the exducer for the dcompressor side. The exhaust housing is 1.04 and i'm pretty sure it's a t4, i could be wrong though. I'm wondering if I shuold swap out the exhaust housing for a smaller one for my car or if this will get me my mid-low 3000 rpms boost (only going to be 8 psi tops). Thanks!

Verdad Gallardo That's the tag that was on it. Again, if you could shed any light on this turbo at all, that would be great. I'm looking for a low boost setup on my heads/cam ls1 just to push it around the 550rwhp mark now. My car is already 410 rwhp on the stock rev limiter. You suggest changing the hotside to a smaller one? If so, I wonder where I could find an exhaust housing that would work. Surely using a different one would cut down some weight too!!! This thing is heavy!
These turbos really do work pretty well, especially for the price and are very proven over on the turbo forums. They are also pretty reliable units that last for quite a while, again especially given the price. I have an S475 1.10 T6 on my Chevy II project going together right now.
What all is done to the motor on that chevyII? Do you recommend me getting a smaller housing on my s4a? I've got slightly higher compression than stock and it's a smaller 62mm turbo, although the exhaust side is still bigger. i'm not sure if it's a t4 or t6 either, i do know that it weighs a TON though!
I will guess his answer and that would be T6 housing and he would recommend the smallest ar they offer since it is a slow spooling turbo.

. Some people half-*** a setup to make it cheap and then end up spending more money again. Do it right the first time...cheaper that way in the long run. We have many customers that have bought the stock S400's and are NOT happy with spool up and they end up selling for a loss and starting over again. Not what I would call smart.....but to each his own. I will say it once and then say it a million times,they are good race turbos....if you have a daily car you enjoy driving and want quick spool, look at something else...plain and simple. We sell a shitload of these turbos and they perform great for the proper application.

really looking for 750-800 rwhp. i am on a budget but can hold out for a better unit if need be. i know the s400 isnt the best turbo around but for the price i have heard great things. i will want to turn the wick up on my car at sometime as well so what would you recommend if not the s400. what about one of your own units that may spool quicker. the engine is a solid roller and can spin to 7500 if need be. trans has a 3500 stall and a t-brake. car weighs about 3100 with me in it. this is not a daily car it will see the street and the track.
