Why buy a rebuilt engine or transmission from us when your mechanic says he can do it cheaper? Because at Automobile Atlanta, we don’t compromise your rebuild with substandard parts or machine work. We go overboard in replacing parts your mechanic would never think to or can’t readily purchase. Plus, from years of experience, we know what wears out. Our rebuilt engine or transmission will, with care, last as long as the new factory one. Our setup is without compromise. We have invested thousands in Porsche factory tools to insure our engines and transmissions are “spot on”. Finally, they are extensively checked during each step of the rebuild process so your new engine is ready to bolt-in and drive away...(choose a part on the right to read more)

Sport throttle bodies are a great addition for those with highly modified cars. They are a great addition for those with full exhaust systems (larger diameters), maf kits, larger displacements, street or race cams, etc. The remanufacturing process includes full inspection of your throttle body to ensure proper operation after the remanufacturing process. We then disassemble and bore the original to a 2.7-inch (70.5 mm) diameter. The entire throttle body is cleaned, degreased and the internals are polished to create more laminar flow. We then machine the shaft to accept larger butterfly's which seamlessly match the bore. All clearances are checked for precision to ensure reliability.

What good is more horsepower if it isn't transferred to the ground? The clutch is the main link between the power your engine produces and the transmission, but all too often it is also the weak link. Many stock clutches simply will not last under harsh driving conditions or continual hard launches. When a car is making more horsepower than stock the factory clutch is under even more strain. This can cause premature clutch wear and costly repair bills. Spec clutch solves this problem with their line of performance clutches. With increased surface area spec clutches give your transmission more 'bite' while increasing reliability and performance.
