1983 Trans Am custom build Fourth Gen LS1 swap

This swap started with an extremely clean third generation TA that we ready to hit the streets with the small block that was in her. We felt that this was the prime example to give her a new look, feel, and add some power!
 
The driveline on this TA has been swapped with a 2002 Trans Am WS6 LS1 engine with an LS6 intake manifold and 4l60E auto transmission. Engine was professionally rebuilt before install and has been test driven over 1,000 miles. The engine has been upgraded with shorty headers, Spectre cold air intake, and a dyno tune. Behind the headers the catless 3” pipe meets a Magnaflow muffler that gives this TA an aggressive tone.

83 Trans Am custom build with Fourth Gen LS1 swap Part II

Cleveland Power and Performance is proud to present this 83 Trans Am custom build with Fourth Gen LS1 swap, which will show you how easily you can update your Gen 3 F-Body with a ton of bolt on Gen 4 Parts! We will be incorporating an LS1 Driveline swap, updated to larger disc brakes, a fourth gen Trans AM Interior, and incorporating every piece of a late model Trans AM into this classic beauty! Long live the 80s!

In the last installment of our 83 Trans Am LS1 swap blog we started off by showing how we received the Trans Am. We received a stock, 5.0L 83 Trans Am with the goal of swapping as many components out of a Fourth Gen as possible. We are going to build this 83 into a modern upholstered, fuel injected, tribute to the awesome era that was the 80’s!

In our last blog we left off with basically a bare shell with no interior and no driveline. We have since started to replace the old with the new. Take a look at the pictures below showing the modifications that we have done to the front cradle to allow for the fitment of the LS1 engine

We also opted to put bigger brakes on the TA to give it some more stopping power. We ordered a kit from bigbrakeupgrade.com that allows us to use fourth gen calipers and rotors on the front by modifying the stock 83 spindles.

The brake kit made installation a breeze and is a huge upgrade in both form and function.

We also began plans on modifying the firewall to allow for the installation of the fourth gen heater box, ac components, brake system and more.

 

Next we will begin mocking up the engine and blueprinting the underhood compartment to figure out where we are going to run our harness, ac lines, etc.

Stay tuned to our blog to see this car come to life.

We want to show all of our customers that this third gen TA could be easily swapped over to a fuel injected LS setup with upgraded interior using almost all parts that we have here in stock.

We will be using the driveline, interior, rear axle, front brakes and more from a donor fourth gen Trans Am. Nearly all of the parts that we will be using in this build are here at Power and Performance, in stock and in our warehouse. This is truly an all “in house” build.

We started by striping the interior of the 83, and taking out the original 305 engine to allow for mock up. We are going to use as much of the fourth gen interior as possible. A good amount of the new interior fits nicely and does not require an extensive amount of modification. Other parts will require a some modification, but in the end will give the 83 a much need update.

This is just the beginning of an exciting build and we will be posting pictures of the process as we go. Please stay tuned to our blog to see this car come to life step by step! Next up we will mock up the interior and drive line to see how everything fits and looks. We will also start on the rear axle and upgraded front brakes. Please feel free to let us know what you think of the build!
