This car is powered by a custom-installed 1995 LT1. It is an all-forged 355 cubic inch V8 controlled by the factory 1995 Sequential Fuel Injection system. No expense was spared to make this custom engine installation appear like it was meant to be there straight from the factory floor.

My goal with the car was to build what was, to me, the ultimate street sleeper. From the exterior, nothing betrays the fact that the car has a highly modified high performance drivetrain. From the option and year-correct rims and grille to the custom factory-style turndown exhaust tips added to the cat-back... this car is meant to appear and even sound as subtle as possible to the unsuspecting guy in the next lane. The only giveaway might be the almost 3000 rpm stall when leaving a light under part throttle. Inside the car, I have added a 145mph speedo and a different stereo head unit (car also comes with stock RS radio.) The ONE giveaway to what the car has under the hood can be found on the passenger's dash where I placed a black and red LT1 emblem from a Corvette. For all the headaches, blood and the continuous nickle and dime expenses while going through grad school... the LT1 emblem seemed necessary.

The interior is in excellent condition and the car features a driver-side air bag, pw, pl, pb, ps, power trunk release and pull-down motor, cloth seats and split rear folding seats.

ENGINE

Notes - This engine was built specifically to be used with a 9 or 12psi supercharger and to withstand at least 650hp under that setup. What this means is that the internals of the engine are of extremely high quality and it was assembled beyond the care or quality of the GM factory. The engine runs normally without a supercharger, it would simply offer MORE power with a supercharger than its counterparts would. Likewise, my eye was on durability. Without the added stresses of a supercharger on the rotating assembly, this engine will last 'forever'. I should note that the car has a new cat in place and the cam is an emissions-legal grind. I have never dyno'd the setup, but a conservative estimate based on other engines with the same parts is 320rwhp or 360-370 horsepower. Again, that is as-is without any supercharger. If you were to add a 9psi P-1sc ATI Procharger, you could easily anticipate 500+ horsepower. Basically, you have a brand new engine that you can either leave untouched and never have to worry about, or you have an engine with all the hard work done already and just have to add a blower to be in the big time.

I never bought or installed a supercharger because I switched attention to the Corvette I had at the teim, and then to the Trans Am (also for sale) http://1994-TA-GT.blogspot.com The Trans Am is naturally-aspirated and makes 415 rear-wheel horsepower which is 491 hp at the flywheel.

Custom engine harness wiring done by Chae Lavin with the LT1 pcm mounted inside the passenger dash in the stock position for a 1991 RS with the OBD plug mounted on the transmission tunnel horizontally across from the radio. The engine alone has over $7800 into it before sensors, electonics, all-new parts and accessories and all conversion-related items.

Custom programming was performed by Bryan Hurter at PCMforless.
