Engine and Transmission
The Turbo Regals(Grand National, T-Type, Turbo T, and GNX) all have Buick's 3.8 liter(231 cubic inch) 90deg. V-6 engine. It should be noted that Buick used turbochargers on this engine from 1978 through the 1987 model years. However, these earlier engines were not as efficient as the later models due to their lack of sequential fuel injection that was introduced in 1984. In 1986, they were reworked once again and among other changes(new passenger side header, crossover, downpipe, intake, turbo, BRF code valvebody, wheels, etc), a charge-air cooler(intercooler) was added, once again increasing power output and efficiency exponentially. These changes were largely the product of a relationship with MacLaren of the UK. GNX engines were enhanced even further. Most notable would be the exotic turbo they received from Garrett which had a ceramic wheel as opposed to the "normal" TBO348 that was used on all other Turbo Regals of that year and the prior year. It should also be noted that there were no Grand Nationals produced in 1983. The T-Type was an available option package in 1983 and could be had with the final version of the non-fuel injection turbo V-6.
. Bought it to learn how to drive a stick before i start the hunt for a C3 Vette… need to relocate to a house with a bigger garage first.
