Even though I am an "old-school" person who like proven parts and methods, I also embrace new technology when applied to our turbo Buicks! 
Most of the T-R's I have done in the past few years have been street performance builds with a attitude, they are kick-ass on the street.
The turbo technology that has been developed in the past 25 years was first exploited with ball bearing center section and then billet wheels. I stayed with old tech turbos as they were simple, affordable, reliable not much gain over the newer stuff.
After being exposed to the new line of the Borg Warner EFR, I found many new and innovative turbos which in my opinion, which are way ahead of the main-stream turbos used in the turbo Buick community.
At this point all B-W EFR turbo utilize 4-bolt housing, but a 3 bolt Buick housing is presently in the works!
The EFR impressed me as it has an internal waste gate which will easily utilize an affordable electronic boost controller.
Another factor is reliability, as the Indy cars all run a B-W turbo for 2 seasons running 200 MPH+ with no service needed, impressive!
The reason for this post is to make our community aware of this product, and you can do your own research on many other details.
I went a step further as I received my EFR 7670 Supercore turbo yesterday, and it will be installed my street Limited. I wanted to take advantage of a 4 bolt turbo with an internal electronic gate and an internal blow-off valve.
Also, not to be different but more efficient, I decided to mount the turbo with the air inlet facing front for a direct cold air intake, and the exhaust will not be restricted by a sharp 90 degree bend inches away from the impeller wheel.
The first mock-up shown below is an approximate position, but I think it will be positioned a little lower especially since we will do a custom alum inner fender, and not deal with the ugly stock plastic piece.
If all goes well, it should be in the road test stage in about a month.

I was really impressed w/ the quality, features, compact size..And all the neat bells/whistles.
