This is a 2003 Pontiac IMSA Fiero that was built off a prototype IMSA body. The owner was able to find this treasure off eBay of all places. Talk about a find. The owner has since has dropped in a 427 c.i. small block which at 13.9:1 compression is putting down around 645 HP and 577 of torque. The transmission that he choose to hook up to the motor is a 1986 Porsche 930 4 speed transmission. He hasn’t been able to test the car out yet but the estimates are a 1/4 mile in 10.5 seconds at 137 mph, 0 to 100 mph in 5.2 seconds, and a top speed of 215 mph. This car is a race car all the way through, from the super sticky race slicks to the full tubular chassis. There is nothing about this car that is street legal. Make sure to check out all the pages on his cardomain page. There is just a ton of very detailed information on the build.
