Here's a shot of the turbo system re-installed on the mockup motor again, the downpipe is now visible through the passenger wheel opening.



We utilized a MagnaFlow 3" stainless dual exhaust system, but removed one leg of the "X" pipe to accommodate the single exhaust of the turbo but keeping the dual mufflers and dual rear tips.

WOW!  I been waiting for more news on this project, and it is looking great!
Looking at the pics, I do not see much room on the pass side for an A/C compressor.....
Is this car not going to have A/C, or are you locating the compressor on the other side?
Can't wait to see more!

Good call on the fiberglass bumpers.  I am planning the same body mods for my Olds.  I plan to paint them the body color.
I've also been toying with the idea of building a lightweight rad core support, as the original old GM unit seems to weigh a ton.

Alain,

This car is not running A/C at this point.   A compressor could be added to the driver side with a custom bracket, but we're out of space on the pass side.

The bumpers will be painted in ALSA's MirraChrome for a 70 - 80% reflectivity, they should look like aluminum when done.   

Here's  a demo of the product...

Looks interesting.  I must be living under a rock (or in Kansas Grin ) because I've never heard of this process before.

One more question.  Are you guys going to use a flex pipe somewhere or a softer mount for the turbo to accomodate for engine movement?
It seems that even if you use solid engine mounts, since the turbo is mounted to the frame, there is going to be some movement which could cause trouble with cracks in your exhaust feed tube???

The engine and turbo are all solid mounted to the frame, so we're not anticipating very much movement.     There is a very slight amount of "give" in the exhaust system as well, so we hope to not have any issues.     The transmission is on a urethane mount to protect the aluminum case.

We decided to run an Edelbrock intake elbow on the EFI system, so some preparations needed to be made to make sure it cleared the hood.



We ended up milling the top of face off, and re-drilled it to accept a Holley LS style throttle body rather than the Ford style.   This would gain us some room under the hood. 






The BTR built engine is running a magnetic pickup mounted on the crank snout for timing, which means it adds 3/8" of an inch to the front of the engine.    We had to re-work all the brackets to extend the pulleys forward 3/8" to make them line up.    Here's the alternator bracket.

Before:



After:



Hard to tell what happened, but it's been cut, stretched, welded, and ground back into shape.

Here, the BTR Performance engine is installed.     Note the reflector ring on the crank.   The revised alternator bracket is installed, but that would eventually change again.   Note the spacer on the steering pump bracket, and the beginning of the fuel system in place.   



This shot shows the FAST fuel distribution block tacked in place, aiming the fuel lines towards the injector rails.   





We hate to drop nuts and bolts, so we try to weld nuts to the backside of brackets and stuff when we can.



After a little refining and welding..



And then to attach it to the original alternator support bar.



Just about ready for prep work and powdercoating.

In this chapter, we're fabricating the hardware and tubing needed to install the Bulleseye Power 75 MM extended tip turbo from Outlaw Turbo Motorsports into our 1971 Olds Cutlass S71 project.   The install required mating the stock exhaust to the custom turbo mount, then sending the exhaust out the custom MagnaFlow 3" dual exhaust system.   Other tasks include installing the large Bell intercooler in the nose of the car, installing a TurboSmart Race Port 50 wastegate, and fabricating all the tubing to manage the airflow.    In the next chapter, we high-temp coat the parts, install the TurboSmart blow off valve, complete the tubing, and address the cooling and oiling systems.

Skipping ahead a little, but we've got great news... the S71 LIVES!     The turbo BTR 421 stroker came to life today powered by a FAST XFI EFI system.    The ISIS Power systems are alive, too!    More later!

As promised, an iPhone video of the S71 Olds turbo running! Had a few issues with the communications cable (my fault) but we got it figured out and now she runs like a champ in the making. Thanks to the crew, BTR Performance, Outlaw Turbo Motorsports, Bullseye Power Turbos, Turbosmart, FAST, MSD, YearOne, BeCool, Royal Purple, and the many others who helped in this phase of the game!
