The original owner wanted a 442, but the pricetag on a 442 was a little out of reach, so this 1971 Oldsmobile Cutlass S was ordrered new with every 442 option except for the 455 Olds engine. It's got the bucket seats, 4-speed, Outside Air Induction fiberglass hood, sway bars, disc brakes... and a 350 4-barrel. It's an interesting car, and here's where the journey back to greatness begins.
Our transformation includes building an Olds diesel-block based stroker motor with the help of BTR Performance , a Bullseye Power turbocharger, FAST XFI fuel injection, a Tremec TKO 600 5-speed, and a pro-touring style suspension and brake package. Follow the build here!
In this chapter of our S71 Olds build, we are completing the install of our Bullseye Power 75 mm turbo, our fabricated turbo piping, Bell intercooler , and the Be Cool Radiator . All of the exhaust tubing and turbine housing parts were coated by Extreme Powder Coating using their 2200° high temperature black ceramic coating to keep them looking new. The charge air tubing was painted with Eastwood's high temperature Nano Ceramic engine paint, which is a very durable paint suitable for parts reaching regular engine temperatures. The be cool radiator module encompasses a pair of Spal electric fans, and Be Cool guarantees it to cool engines up to 1000 HP. We installed a Turbo Smart Reaceport blow-off valve inline with the air intake to help keep the turbo spooled-up during shifts. To help reduce underhood air temperatures and to make our turbo system more efficient, we installed a DEI Titanium Turbo Shield , which is made from lava rock strands that can withstand temperatures over 1800°. We also wrapped our turbo exhaust with DEI Titanium Exhaust Wrap to keep the hot exhaust gas in the tubing and underhood temperatures down. A K & N air filter and various silicone connectors from IntakeHoses.com completed the intake tubing. In the coming chapters, we will complete the ISIS Intelligent Multiplex wiring system install and FAST Fuel Injection installs before firing up the S71 Olds!
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.
This is part 9 in a multi-part series covering the custom 422 cubic-inch stroker engine build performed by master engine builder Bill Trovato at BTR Performance for our turbocharged 1971 Olds project called the "S71". In this chapter, Trovato takes us through the process of installing the MSD Pro-Billet distributor that has been modified by FAST to work with the FAST XFI fuel injection system. Although this video series features and Olds engine, the valuable, race-proven techniques shown by Trovato apply to any performance engine build.
This is part 8 in a multi-part series covering the custom 422 cubic-inch stroker engine build performed by master engine builder Bill Trovato at BTR Performance for our turbocharged 1971 Olds project called the "S71". This video outlines the choice of the Edelbrock intake manifold and the installation of the FAST fuel injectors and rails. Although this video series features and Olds engine, the valuable, race-proven techniques shown by Trovato apply to any performance engine build.
This is part 7 in a multi-part series covering the custom 422 cubic-inch stroker engine build performed by master engine builder Bill Trovato at BTR Performance for our turbocharged 1971 Olds project called the "S71". This time, Trovato installs the roller lifters, Comp Cams pushrods and rocker arms, and shows us how to adjust them. Although this video series features and Olds engine, the valuable, race-proven techniques shown by Trovato apply to any performance engine build.
This is part 6 in a multi-part series covering the custom 422 cubic-inch stroker engine build performed by master engine builder Bill Trovato at BTR Performance for our turbocharged 1971 Olds project called the "S71". This time, Trovato shows us how to properly torque the Edelbrock aluminum heads using ARP fasteners and molybdenum lube. Although this video series features and Olds engine, the valuable, race-proven techniques shown by Trovato apply to any performance engine build.
This is part 5 in a multi-part series covering the custom 422 cubic-inch stroker engine build performed by master engine builder Bill Trovato at BTR Performance for our turbocharged 1971 Olds project called the "S71". This time, Trovato installs the custom grind Comp camshaft and Edelbrock aluminum cylinder heads. Although this video series features and Olds engine, the valuable, race-proven techniques shown by Trovato apply to any performance engine build.
This is the fourth in a multi-part series covering the custom 422 cubic-inch stroker engine build performed by master engine builder Bill Trovato at BTR Performance for our turbocharged 1971 Olds project called the "S71". In this installment, Trovato installs the piston rings on the pistons and installs the pistons and rods on the crankshaft. Although this video series features and Olds engine, the valuable, race-proven techniques shown by Trovato apply to any performance engine build.
