The notes behind the car

Research

Model guides, trim ladders, engine families and market differences — the homework that decides what the EG3 should and shouldn't become. One thread: the Honda Civic EG, from the carburetted EG3 at the bottom up to the VTEC cars that are only ever quiet, long-term directions.

Generation guide

The EG generation, briefly

The 5th-generation Civic (1991–1995) is what everyone calls 'the EG', but the codes are more precise than that — and market-dependent.

Years: Launched in Japan September 1991, built there until August 1995. Europe broadly 1991–1995; North America as 1992–1995 model years. The EK 6th-gen followed from late 1995.
Bodies: 3-door hatchback (the enthusiast favourite), 4-door sedan (the 'Ferio' in Japan), 2-door coupe, and the del Sol targa.
Code scheme: A two-letter prefix (EG / EH / EJ) plus a digit. The prefix encodes body and market, the digit encodes engine and trim. Strictly, EG = JDM/Euro hatches and JDM sedans; USDM hatches are EH; coupes are EJ. The community uses 'EG' as shorthand for the whole generation.
Suspension: Double wishbone at BOTH ends — not a multi-link rear, a point the internet repeatedly gets wrong. Honda marketed it as '4-wheel double wishbone'. The multi-link rear arrived with the following EK generation. This front and rear geometry is the EG's real engineering advantage over strut-suspended rivals.

Trim ladder

The hatchback ladder (Europe)

The European hatch range climbs cleanly in both chassis code and engine size — a textbook ascending ladder, with the EG3 at the bottom and the EG6 at the top.

Note: Two letters and a digit do a lot of work here. The digit climbs with the engine: bigger, then injected, then VTEC, then twin-cam VTEC. The EG3 and EG6 share a shell and almost nothing else mechanically. Everything above the EG3 is, for now, only a quiet long-term direction — not an active project.

Code · trim	Engine	Valvetrain	Power
EG3 · DX	1.3 D13B2	SOHC, carb	75 PS
EG4 · LSi/VEi	1.5 D15B2 / D15Z1	SOHC / VTEC-E	90–92 PS
EG5 · ESi	1.6 D16Z6	SOHC VTEC	125 PS
EG6 · VTi	1.6 B16A2	DOHC VTEC	160 PS

Engine family

D-series vs B-series — why an EG3 isn't an EG6

The gap between the base EG3 and the EG6 SiR isn't a state of tune — it's two different engine families. Same shell, completely different machine.

D-series: The EG3/EG4/EG5 engines: single-cam (SOHC). Spans carb economy units (D13B2, D15B), lean-burn VTEC-E (D15Z1), and SOHC VTEC up to the 125 PS D16Z6. Honest, light, modest.
B-series: The EG6/EG9 SiR/VTi engine (B16A / B16A2): a separate DOHC VTEC family — the world's first production VTEC engine. ~108 PS per litre, redline past 8,000 rpm.
EG3 vs EG6, in numbers: Euro EG3: 1,343 cc, SOHC carb, 9.0:1, 75 PS. JDM EG6 SiR: 1,595 cc, DOHC VTEC, 10.4:1, 172 PS @ 7,400 rpm. Same body, 2.3× the power, a different operating regime entirely.
The point: Swapping a B-series into an EG3 and badging it an EG6 borrows an identity that was never the car's. It's a costume. The EG3's value is in being the honest D-series base car — which is exactly why this one stays carburetted and gets restored, not swapped.

Market differences

Market differences (and the EG3 confusion)

The same chassis code means different cars in different markets — which is exactly why the EG3's engine is argued about online.

EG3 — market split: Europe (DX): 1.3 D13B2, 75 PS. Japan (ML): 1.5 D15B single carb — Japan rarely sold a 1.3 Civic in this era. Same code, different engine. State which market you mean.
Naming trap — 'VTi': JDM VTi = an EG4 with a 1.5 SOHC VTEC (130 PS). European VTi = an EG6 with the 1.6 DOHC B16A2 (160 PS). Same badge, different chassis, ~30 PS apart.
USA: USDM hatches use EH codes, not EG. No USDM Civic ever got a factory B16A — only the del Sol VTEC did. That absence is why the B-swap became so culturally embedded in the US scene.

Ownership notesStill researching

EG3 — ownership, buying and restoration notes

What a 30-year-old carburetted Civic actually asks for — and the things this car is already showing. Marked approximate where it's community knowledge rather than a hard figure.

The carb system(approx.): The PGM-CARB's idle and vacuum circuits are the real maintenance, not power. Perished vacuum hoses and a carbon-fouled IACV cause exactly the symptoms this car has — hunting/rough idle, cold-start stalling, needing throttle to start and heavy fuel use. A full vacuum-line refresh and IACV clean come before chasing anything else.
Timing belt(approx.): Interference engine — a snapped belt bends valves. Service interval around 90,000 km; on any unknown car, treat it as overdue and do the water pump at the same time.
Rust(approx.): Standard 1990s Honda pattern: rear arch lips, sills, floor pans under the carpet, spare-wheel well, front strut towers. Surface rust on arches is manageable; soft floors and strut towers are structural and can end a project.
Parts(approx.): Consumables (filters, belts, gaskets, ignition) remain available. The D13B2 is an orphan in tuning culture, so there's no performance aftermarket — which suits this car. Body rubber and weatherstrip are the genuine scarcity, and locally to Cebu some EG3 parts may be harder to source; some seals come only from breakers or NOS stock.
Suspension(approx.): Assume a full bush refresh on any unrestored example. The double-wishbone geometry is sensitive to bush condition — worn rubber makes a genuinely good chassis feel vague and hides how capable it is.
