Key Takeaways
- Released in Japan in autumn 1991, replacing the previous-generation Civic
- The SiR and SiR-II used "the famed B16A twin-cam capable of 170 horsepower" — "106.25 hp/L" in 1992
- JDM only: the SiR was "a forbidden fruit sold solely in the Japan domestic market"
- Double-wishbone and trailing-arm four-wheel independent suspension, softened from the previous car
- Body styles included the Ferio sedan, the hatchback "with a clever clamshell tailgate", and "for the first time in Civic history, a true two-door coupe"
- Biggest buying risk: a retrofitted B16 rather than a factory SiR — some swap shops did "things like hacking together OEM mounts to shoehorn the engines in"

Should You Buy a Honda Civic EG6?
Why You'll Love It
- A factory 100+ hp-per-litre hatchback "At the top end was the SiR and SiR-II, with the famed B16A twin-cam capable of 170 horsepower, giving it an astounding Lamborghini-esque 106.25 hp/L specific output way back in 1992."
- The chassis under it is the real story Honda "softened up the absolutely stellar double-wishbone and trailing arm four-wheel independent suspension, upped the ante on its lineup of race-derived engines", and smoothed the body into "an icon of the organic 90s style".
- Genuine race pedigree, straight away "From the onset the EG was a tour de force on the circuit, with Mugen and Mooncraft sweeping the JTC-3 class podium in 1992 and 1993."
- VTEC as Honda built it The B16A used "the world's first variable valve timing and lift technology, VTEC", which switches between cam profiles under ECU control "sensing inputs such as engine speed, engine load, and vehicle speed".
Why You Might Not
- Never sold new outside Japan The SiR was "a forbidden fruit sold solely in the Japan domestic market", so a car outside Japan is an import with the paperwork and parts consequences that implies.
- The engine may not be the one it left the factory with specialist swap shops "began charging thousands of dollars for JDM or Del Sol B16 retrofits. Some were very dodgy, doing things like hacking together OEM mounts to shoehorn the engines in."
- Most survivors have been modified Enthusiasts moved on from B-series swaps to "even other swaps including the mammoth 2.2-liter H22 from Preludes of the era" — an unmolested car is the exception, not the rule.
- US buyers were never offered the real thing Honda did eventually "give us one variant of the EG with the venerated B16A, albeit de-tuned to 160 horsepower" — in the Del Sol, not the hatchback.
Who Should NOT Buy This
- Buyers who want originality but will not verify the engine is the factory unit — dodgy swaps included "hacking together OEM mounts to shoehorn the engines in"
- Buyers who expect a US-market equivalent: the SiR was "a forbidden fruit sold solely in the Japan domestic market"
- Buyers who want torque rather than revs — this is a high-specific-output naturally aspirated engine, "106.25 hp/L" in 1992
- Buyers who need dealer parts support outside Japan for a JDM-only trim
Common Issues & Solutions
| Issue | Cause | Solution | Est. Cost |
|---|---|---|---|
| Retrofitted engine presented as factory | specialist swap shops "began charging thousands of dollars for JDM or Del Sol B16 retrofits. Some were very dodgy, doing things like hacking together OEM mounts to shoehorn the engines in." | Verify engine and chassis numbers against the car's paperwork, and inspect the mounts and loom for improvised work before accepting a car as an original SiR. | An independent inspection is cheaper than discovering the swap after purchase. |
| Non-factory engine swaps beyond the B-series | Owners went further than B16 swaps, "even other swaps including the mammoth 2.2-liter H22 from Preludes of the era". | Establish what is actually installed before valuing the car, and treat any swap as a modification with its own service history. | Price the car as what it is, not as what the badge says. |
Differences between JDM & USDM
The distinction that matters on this generation is the engine. In Japan, "at the top end was the SiR and SiR-II, with the famed B16A twin-cam capable of 170 horsepower", and that car was "a forbidden fruit sold solely in the Japan domestic market". The US range topped out with a different unit: "for Americans, the D16Z6 engine in the range-topping Civic Si was the big story", and it was "the first availability of Honda's VTEC system in the American Civic line that cemented its popularity". Honda eventually brought the B16A to the US, but in the Del Sol and "de-tuned to 160 horsepower". The consequence for a buyer today is that a B16A in a US-titled hatchback is almost certainly a retrofit rather than a factory fitment — and some of those retrofits involved "hacking together OEM mounts to shoehorn the engines in". Importing a genuine SiR runs on 49 CFR 591.5's condition that "the vehicle is 25 or more years old".

The Buyer's Read
The EG6 is the Japanese-market SiR hatchback, and the car's whole appeal sits in one number. "At the top end was the SiR and SiR-II, with the famed B16A twin-cam capable of 170 horsepower, giving it an astounding Lamborghini-esque 106.25 hp/L specific output way back in 1992." That engine used "the world's first variable valve timing and lift technology, VTEC", switching cam profiles under ECU control "sensing inputs such as engine speed, engine load, and vehicle speed".
Underneath, this generation is a refinement of a very good car. Honda "softened up the absolutely stellar double-wishbone and trailing arm four-wheel independent suspension, upped the ante on its lineup of race-derived engines", and the range covered "a sedan (called the Civic Ferio in Japan), the standard hatchback with a clever clamshell tailgate, and for the first time in Civic history, a true two-door coupe". It was immediately competitive in racing: "from the onset the EG was a tour de force on the circuit, with Mugen and Mooncraft sweeping the JTC-3 class podium in 1992 and 1993".
The buying problem is provenance, not mechanics. The SiR was "a forbidden fruit sold solely in the Japan domestic market", so outside Japan the B16A arrived mostly through the aftermarket. specialist swap shops "began charging thousands of dollars for JDM or Del Sol B16 retrofits. Some were very dodgy, doing things like hacking together OEM mounts to shoehorn the engines in." Later owners went further still, "even other swaps including the mammoth 2.2-liter H22 from Preludes of the era".
So verify before you value. Check the engine and chassis numbers against the paperwork, look hard at the mounts and the loom, and establish whether you are looking at a genuine SiR or a well-presented conversion. If you are importing one into the US, 49 CFR 591.5 asks only that "the vehicle is 25 or more years old" — the harder part is finding a car that is still what it left the factory as.
Frequently Asked Questions
- When did this generation appear, and where?
- Its "story starts in fall of 1991, when it was released for the Japanese market as a 1991 model year replacement for the beloved EF Civic. A few months later, the virtually identical 1992 model was released stateside and in the rest of the world."
- How much power does the SiR make?
- "At the top end was the SiR and SiR-II, with the famed B16A twin-cam capable of 170 horsepower, giving it an astounding Lamborghini-esque 106.25 hp/L specific output way back in 1992."
- Could you buy an SiR in the US?
- No. It was "a forbidden fruit sold solely in the Japan domestic market". The closest the US came was the Del Sol, where Honda fitted "the venerated B16A, albeit de-tuned to 160 horsepower".
- What body styles were there?
- "Body styles included a sedan (called the Civic Ferio in Japan), the standard hatchback with a clever clamshell tailgate, and for the first time in Civic history, a true two-door coupe."
- What is the biggest risk when buying one?
- A swapped engine sold as an original. specialist swap shops "began charging thousands of dollars for JDM or Del Sol B16 retrofits. Some were very dodgy, doing things like hacking together OEM mounts to shoehorn the engines in."
- Can I import one into the US?
- Under 49 CFR 591.5 the FMVSS exemption condition is that "the vehicle is 25 or more years old" — confirm the specific car's manufacture date and current import, EPA and state requirements.
