In his presentation, Bill will tell the REAL story behind the creation of the 1989 20th Anniversary Pontiac Turbo Trans Am. The story of bringing the TTA to production is a tale filled with road blocks and creative engineering. Not only was there only a small budget to work with but GM Corporate politics tried to block the release of a Buick powered Pontiac Trans Am.
Bill Owen, the Buick engineer, who directed and assisted the merging of the Buick engine with the Pontiac Trans Am chassis will reveal what makes the 20th Anniversary Turbo TA so special. It is a complete mechanical package, and not just some tape stripes. Starting with the engine, Pontiac borrowed Buick’s 3.8 liter (231cid) V6 turbo power-plant from the fabled 1986-87 Grand National. Some difference exists between the TTA motor and the GN version. Different heads were necessary in order to squeeze the motor between the strut towers. These heads, adapted from the transverse FWD version of the 3.8 liter motor, have the added benefit of improved exhaust flow and combustion chamber design. Subsequently, different pistons were required in order to maintain combustion chamber volume. Other changes to the TTA motor are a cross-drilled crankshaft, larger 12 fin/inch in place of the GN’s 10 fin/inch design, specially-designed , a higher-pressure Bosch 237 fuel pressure regulator, and a recalibrated engine control GNX-style intercooler stainless exhaust headers module.
