RE: 323 Information
 

Engine Codes

B6 - The B6 is the common engine found in the BF (1986-1989) 323s. The B6 is a 1.6L SOHC 8-valve normally aspirated engine rated at 82hp from the factory. The "B" stands for the Mazda "B" series block used in the engine, and the "6" comes from the 1.6 liters of displacement.

B6T - The B6T is the engine found in the BF 323 GT and GTX, as well as the early 90's Mercury Capri XR-2. Like the B6, it uses the Mazda B series engine block and displaces 1.6 liters, but the B6T has the added benefit of an turbocharger/intercooler setup. The B6T has a DOHC cylinder head and is rated at 132hp from the factory. The only main difference between the B6T's block and that of the non-turbo B6 is that the B6T has oil squirters in the cylinders to aid cooling.

BP - The BP engine is the common engine found in the BF (1990-1994) 323. It uses a block design which is virtually identical to the earlier Mazda B series block, but one which is physically longer in order to support more displacement. The BP engine displaces 1.8 liters, and can be found in SOHC and DOHC versions.

BPT - The BPT is the engine found in the BG 323 GTX/GTR, and was never available in North America. The engine uses a DOHC cylinder head, and comes in two versions - a 185hp GTX version, and a 210hp GTR version. The differences between the GTX and GTR include stronger internals and a beefier turbo in the GTR version.

Trim Levels ~Part 1~

DX - This is the base model of the 323. The DX's had very few options. Usually they don't have a passenger side mirror, and some came without A/C.

SE - This is the first step up. The SE's had a few options, and usually came with both side view mirrors. A little bit nicer than the DX. Some were labelled "Sport", but as far as I know, there is no difference between an "SE" and "SE Sport".

LX - This is the "luxury" model of the 323. The LX came with nicer upholstery on the seats, nicer (upholstered as opposed to vynl) door panels, and nicer carpeting. Usually the LX came with a center console, and some even had sunroofs. Another way to tell an LX from a lower model was that the side view mirrors were painted to match the body, and the trim around the windows and the center pillar were painted black, like the GT and GTX. Usually had alloy wheels instead of hubcaps, and had an optional tire size that was slightly different from the base models.

Trim Levels ~PART 2 1/2~

GT - Usually a GT refers to a limited run 2WD turbocharged sedan version of the 323 that was only available in 1988 (some claim to have seen 1989 models, but all the literature I have seen over the years points to the turbo GT's availability being limited to one year). However, in Canada, some dealers converted some base 323 hatchbacks in to "GT" hatchbacks in '86 and '87. These GT hatchbacks still had the SOHC non-turbo engine and were front wheel drive, but they added a lot of the higher-end options only available on the turbo models (which at the time were only available overseas), such as the sunroof....

Trim Levels ~PART 4~

GTX - The GTX was made from 1986-1994, but was only available in North America in 1988 and 1989. The GTX was a 4 wheel drive, turbocharged and intercooled hatchback. The GTX was made because of the homologation rule in WRC rallying. The GTX was basically a seriously de-tuned rally car for the street. In North America, only 1,243 were sold, making the GTX a rare car. The GTX had the luxury options from the LX, as well as the extra goodies previously mentioned from the turbo GT (minus the adjustable suspension). There were side skirts available for the GTX from the factory, and the GTX also had two hatch spoilers - one at the top and another at the bottom.
GTR - The GTR was even more limited in production than the GTX. The GTR got a souped up version of the BPT engine, and was basically ready to race straight from the showroom floor. 210 horsepower - nearly unheard of at the time - and 4 wheel drive was all you needed to know about this bad boy.
GTAe - GTAe refers to an EXTREMELY small number of GTXs/GTRs that were modified and built to be used specifically for rally racing by Mazda. That is, these cars were not intended to be driven on the street.

Trim Levels ~PART 3~

GT - Continue'd: ...The GT hatchbacks usually have a "GT" decal on the side of the car. The turbo GT was only available as a sedan and came with all of the high-end options from the LX, as well as some other goodies such as an optional adjustable suspension, which was controlled via a switch on the dashboard and could switch between a "normal" mode, one which gave you a slightly better ride quality, and one that was firm for better handling. The turbo GT's also came with different bumpers, with openings in the front bumper to aid cooling on the intercooler and radiator. The bumpers' styling was slightly different from the non-turbo 323s, and were painted to match the body.
