Parts for your 1987 Suzuki Jimny-Egr valve

1987 Suzuki Jimny (Sierra SJ413) EGR valve – is it relevant for AU/NZ?

Short answer: for most Australian and New Zealand–delivered 1987 Suzuki Jimny/Sierra SJ413s, an EGR (exhaust gas recirculation) valve wasn’t fitted, so an “EGR valve” isn’t a relevant service item on these vehicles. This is supported by the Suzuki SJ413/Sierra Factory Service Manual for carburetted G13A engines (Emission Control System chapter), which lists EGR as market-specific and shows the EGR layout only for North American models. Likewise, Suzuki’s parts catalogues for AU/NZ SJ70/SJ80 variants don’t list an EGR valve, EGR pipe, or EGR modulator for 1987 models, whereas the North American Samurai catalog does. Period emissions guidance (ADR 37/00 for AU and equivalent NZ standards of the era) also allowed compliance without EGR on small, low-compression, carburetted engines.

Why wasn’t it used locally? Suzuki met NOx and HC limits in AU/NZ with a simpler package: PCV, evaporative control (charcoal canister), carefully calibrated ignition and fuelling, and—on many examples—a catalytic converter and air injection depending on the exact build. That let them skip EGR hardware, keeping the intake free of hot exhaust plumbing and the vacuum system simpler. For off‑roaders, that meant fewer bits to clog or fail when the going gets dusty and bumpy.

There are a couple of caveats. Grey imports, US-spec Samurais, and some JDM Jimnys of the era can have a factory EGR system. Engine swaps (e.g., G13B, G16 conversions) may also bring EGR gear across. If you’re not sure what you’ve got under the bonnet, a quick visual check helps:

• No AU/NZ 1987 Sierra usually has an EGR valve bolted to the intake manifold with a steel pipe looping to the exhaust manifold.
• No vacuum EGR modulator or EGR solenoid on the inner guard or manifold area.
• Vacuum diagram under the bonnet won’t show “EGR” circuits on local-delivery cars, US diagrams do.

If your 1987 Jimny/Sierra is a local-delivery AU/NZ vehicle and stock, there’s no EGR valve to service or replace. Focus routine maintenance on the carb tune, ignition timing, PCV operation, evap hoses, and exhaust integrity. If you’ve got an import with EGR, keep it intact and functioning—tampering with emissions gear can be illegal and can affect roadworthiness (WOF/rego) and how well it runs.

Popular questions about the 1987 Suzuki Jimny EGR valve

Did any 1987 Jimny/Sierra sold new in Australia or New Zealand have an EGR valve?
Generally no. Factory literature for AU/NZ SJ413 carb models shows no EGR hardware fitted. EGR appears on North American Samurai models of the same era and on some Japanese‑market variants. If yours was sold new locally and is still stock, it almost certainly won’t have EGR.

How can I tell if my imported 1987 Samurai/Jimny has EGR?
Look for a small, saucer-shaped valve on the intake manifold with a metal tube running to the exhaust manifold, plus vacuum hoses to an EGR modulator/solenoid. The bonnet vacuum diagram (if present) will clearly label “EGR.” If you see those, it’s an EGR-equipped import, and the system should be kept functional for emissions compliance and proper drivability.

Is it legal to delete or retrofit EGR on a 1987 Jimny/Sierra?
For AU/NZ-delivered 1987 cars that never had EGR, there’s nothing to delete. For imported vehicles that do have EGR, removing or defeating it can breach emissions rules and may risk failing WOF/roadworthy or attracting penalties. Retrofitting EGR to a local car isn’t necessary for compliance and offers no real upside on a stock 1.3 carby setup.
