So ive looked everywhere and I'm really confused why my ef hatch with a d16a6 has a 5 speed tranny and vinyl interior. I was told they only come with 4 speeds and I have a 5th. I don't know much about my car so if someone could help me out that would be awesome. D16a6 5 speed trans could it be because its a Canada model? (Says so in the door frame)

 

From my understanding only the very base model had the 4 speed. My buddy has that particular model. It has a 4 speed and the motor is a d15b1. His was also built in Canada.

 

STD

1989 Civic STD 3-door
The base model with the lowest price and lowest standard (vinyl seats) interior, instrumentation, engine output and transmission. It was only available as a Hatchback. Engine was D15B1 16V SOHC, with dual port throttle body injection, 75 hp (55.9 kW) with restrictor on the tandem valve, and catalytic converter integrated into the exhaust manifold. Manual transmissions were 4-speed with cable operated clutch (5-speed in Canada). Automatic 4-speed transmission was also available.

DX

1990 Civic DX 4-door; including automatic seat belts
Available as Hatchback, Sedan and Wagon, this had cloth seats, optional power steering, optional rear wash/wiper, optional clock, optional passenger door mirror and optional wheel covers. Engines were D15B2 16V SOHC with slightly higher output 92 hp (68.6 kW) due to an improved profile on the inlet side of the Single Overhead Cam and unrestricted tandem valve. Manual transmissions came as 5-speed with cable operated clutch. Automatic transmission was available as an option.

LX

Available only as a Sedan, this had a higher level interior with tachometer instrumentation, electric windows, electric door locks, electric door mirrors, clock and wheel covers as standard. Engines were D15B2 16V SOHC, same as the DX, with 5-speed cable clutch transmission. 4- speed automatic transmission was optional.

EX

Available only as a Sedan for 1990 and 1991 model years, this was the top of the Civic line with all LX standard features, and the D16A6 16V SOHC engine with 4-point injection, making 105 hp and 100 ft-lbs. It also had upgraded brakes on the front with 10.3" disks vs. the 9.5" on the STD, DX, LX and SI models. The 1991 had a higher geared steering rack - 3.1 turns lock to lock vs 4 for other and prior models.

SI

1991 Honda Civic Si
Initially, the Civic Si hatchback was absent from the lineup, with only the CRX Si offered for the 1988 model year. That changed, however, for 1989, and the Civic Si hatchback was reintroduced, along with a 3-hp upgrade for the D16 engine across all Si trims (making 108 hp, 1988 CR-X Si 105 hp). This was the sportiest US market Civic, only available as a hatchback. The engine fitted was the D16A6 16-valve SOHC with 4-point injection and output of 108 hp (81 kW). It weighed in at 2,286 lb (1,037 kg), achieving a factory 0–60 mph of 8.1 seconds; and a quarter-mile time of 16.2 at 82 mph (132 km/h).[4]

The main standard features of the Si trim were the power sun roof/moon roof, tachometer, passenger door mirror, color matched bumpers, dash clock, larger exhaust, front and rear anti-roll bars, 14" steel wheels with covers, and slightly deeper bucket sport seats. There was no power steering and no automatic transmission available (except in Canada). Additional options were air conditioning and fog lights, as well as the different Honda Genuine Accessory alloy wheels.[5] In other markets, more powerful D16A7 and D16A9 engines were used instead, which made 122 hp (91 kW) and 132 hp (98 kW) respectively.

Compared to the previous generation, the Civic Si saw an improvement in handling, in part due to the double-wishbone suspension at all four corners and lower wind drag due to the sleeker body shape. As with all other trims, the Civic Si received a slight visual upgrade in late 1989, featuring revised bumpers and tail lights.

Due to the difference in engine output and modification potential between the American and JDM models, the second-generation Si sparked a popular trend of engine swapping, where tuners would replace the D-series power plant with a more powerful B-series motor.

 

I don't have a moon roof, and it doesn't look like a crx. Same exact body as 91ef hatchback. 2 doors and the hatch. Motor is stamped as d16a6. Vinyl/leather interior. (Its grey interior, Head liner and back seats all match) no cup holders just a stick ash tray and radio. Keep in mind its has a 5 speed tranny. So was a swap done?

 

Was originally red if that helps at all

 

1.6L 16valve

 

VIN check will tell you all!



At the top of this forum, there is a TOOLS tab that has a VIN decoder.

 

I wouldn't rely on the decoder, it spit out the wrong info for my car.

 

I would guess that somebody swapped the motor and tranny at some time.

 

If it's a DX EX or Si then the 5spd may be original. But if the H emblem on hood and trunk are the only badging, then it has probably had a complete drivetrain swap.
