Some engines are just transport. The B18C is not one of them. It is the engine that made the Integra GS-R and Type R famous, the one that pulls hard all the way to 8,000 rpm and makes that VTEC sound people still talk about at car meets. If you have been hunting for a Honda B18C engine for sale, whether to save an Integra or to build a Civic, you already know why.
We sell genuine, tested, fairly used B18C engines and ship them worldwide. Every engine comes with photos of the real unit, its engine number recorded, a written quote and a warranty. No mystery engines, no blurry pictures, no guessing.

In this guide we cover the B18C specs, every main version, which cars it came in, how swaps work, the faults to look for, seven checks before you buy a Honda B18C engine for sale and how to look after it once it is in.
What Is the Honda B18C?
The B18C is a 1.8 litre inline four from the Honda B engine family. Honda launched it in 1993 in the Japanese Integra SiR, and it went on to power the Integra GS-R, the Integra Type R and some European Civics. It has an aluminium block and head, twin overhead cams and Honda’s VTEC system, which switches to a wilder cam profile at high revs.
What makes it special is how it delivers power. Below the VTEC switch point it drives like a normal small engine. Above it, the engine changes character and pulls harder the closer it gets to redline. The Type R version was one of the first production engines to make over 100 horsepower per litre without a turbo.
Thirty years on, a Honda B18C engine for sale is still in demand from Integra owners, Civic builders and track drivers. That demand is also why you need to be careful about where you buy one.

Every Main B18C Version
B18C (JDM Integra SiR)
The original. About 180 PS from the Japanese Integra SiR. Most JDM imports are this engine, and it is the Honda B18C engine for sale our product page price is based on.
B18C1 (North American Integra GS-R)
About 170 hp, with slightly lower compression than the JDM engine. Common in North America, where a lot of Integras were sold.
B18C5 and the JDM 96 spec R
The Type R engines. Higher compression pistons, hand-finished ports, lighter valves, a different intake manifold and a higher redline. They are rarer and cost more. We quote them separately.
B18C4
Used in the European Civic 1.8 VTi. A close cousin of the GS-R engine.
B18C2, B18C3, B18C6 and B18C7
Versions for other markets, including Australia, where the B18C7 powered the local Integra Type R.
The engine code and number are stamped on a flat pad on the front of the block, near the gearbox. Before you pick a Honda B18C engine for sale, know which version you want and what you are putting it in.
Cars That Came With the B18C
- Honda and Acura Integra DC2 and DB8, about 1994 to 2001
- Integra Type R in Japan, North America, Europe and Australia
- Honda Civic 1.8 VTi in Europe
That is a short list, but the swap list is far longer. A Honda B18C engine for sale ends up in Civics, CR-Xs and Del Sols far more often than in the Integras it came from.
B18C Swaps: What You Need
The B18C is one of the easiest serious engine swaps out there, but it still needs the right parts.
Engine mounts
Civics from 1992 to 2000 (EG and EK) and the Del Sol use mounts that suit B-series engines, often with a swap mount kit. Older CR-Xs need their own kit.
Gearbox
You need a B-series hydraulic gearbox. GS-R and Type R boxes have closer ratios, and many Type R boxes came with a limited slip differential. We can often supply a gearbox with your Honda B18C engine for sale.
Engine computer
The engine needs an ECU that suits it. JDM engines often come with their original computer. Some builders use a chipped computer and a custom tune instead.
Wiring
Hondas from this period come in OBD0, OBD1 and OBD2 wiring, and they do not always match. You may need a conversion harness or adapter. Plan this before the engine arrives.
Axles, shifter and cooling
Depending on the car, you may need different axles, a shifter linkage and a better radiator. Do not skip brakes either. More power needs more stopping.
Tell us your chassis and plan and we will help you work out exactly which Honda B18C engine for sale and extra parts make the swap simplest.
Why the Engine Number Matters
B-series engines have been stolen in large numbers over the years, and some countries check engine numbers when a car is registered or inspected. A seller who cannot show you a clean, readable engine number is a seller to walk away from. Ground-off or restamped numbers are a bad sign.
Every Honda B18C engine for sale we ship has its number photographed and printed on your quote and paperwork. That protects you at registration time and when you sell the car later.
Known B18C Problems
Oil consumption
High mileage engines that spent their lives near redline can burn a bit of oil. A compression and leak-down test tells you a lot about ring condition.
VTEC solenoid and oil pressure switch leaks
The gasket behind the VTEC solenoid and the pressure switch next to it are common leak points. Cheap to fix.
Distributor
The distributor O-ring leaks oil, and the igniter or coil inside can fail with age, causing a no-start or misfire.
Timing belt
It is an interference engine. If the history is unknown, change the belt and water pump before you use the high revs.
Abuse
The honest truth is that many of these engines lived hard lives. Missed shifts, bouncing off the limiter and cheap oil all take their toll. That is why we test before we sell any Honda B18C engine for sale.
7 Proven Checks Before You Buy a Honda B18C Engine for Sale
1. Confirm it is a real B18C
Some sellers pass off a B18B, which is the non-VTEC 1.8, or a mix of parts as a B18C. Look for the VTEC solenoid, the correct head and the right code on the block.
2. Check the engine number
Clean, readable and matching the paperwork. No exceptions.
3. Ask for compression and leak-down results
Compression should be even across all four cylinders. Leak-down shows whether the rings and valves are sealing.
4. Look at the cams and rockers
A photo under the valve cover shows if the engine had regular oil changes. Scored cams or heavy varnish are warnings.
5. Ask what it came out of
An engine from a standard road car is usually a safer bet than one from a car that was raced every weekend.
6. Know what is included
Intake, distributor, computer, harness, gearbox. Get the list in writing so the Honda B18C engine for sale you receive matches what you paid for.
7. Get the warranty in writing
Know what it covers and how long it lasts before you pay.
How We Test Every Honda B18C Engine for Sale
- Record the engine number, code and donor car where known
- Compression test on all four cylinders
- Leak-down test where possible
- Check oil and coolant for contamination
- Inspect cams and rockers under the valve cover
- Turn the engine over by hand and listen for noise
- Photograph the engine and the engine number
- Drain, cap and pack for shipping
More on our process is in our guide to tested used engines.
What Comes With the Engine
A complete engine normally includes the block and head, intake manifold, throttle body, fuel rail, injectors, distributor where fitted, exhaust manifold, oil pan and oil pump. Gearboxes, computers and harnesses are available on some engines at extra cost. Your quote lists exactly what comes with your Honda B18C engine for sale.
Honda B18C Engine Price: What Affects It
The current price is on our Honda B18C product page. That price is for a complete, fairly used JDM B18C. The final number depends on:
- The version, with Type R engines costing the most
- Test results and mileage
- Whether you add a gearbox, computer or harness
- Shipping method and destination
Prices on good B18C engines have climbed over the years as clean ones get harder to find. Budget for mounts, wiring, a clutch and a timing belt kit too. Our replacement engine cost guide helps you plan the whole job.
Used, Rebuilt or Built?
A tested used engine is the quickest and cheapest way to get a B18C running. A fresh rebuild can be great if done by someone who knows Hondas, but quality varies a lot. A fully built engine with forged parts only makes sense for big power goals. Our guide to remanufactured vs rebuilt engines explains the difference. For most street cars, an original, tested Honda B18C engine for sale is the sensible pick.
Fitting Tips From the Workshop
- Fit a new timing belt and water pump unless the history is known.
- Replace the VTEC solenoid gasket, valve cover gasket and distributor O-ring.
- Fit new spark plugs and check the plug wires.
- Fit a new clutch and resurface or replace the flywheel.
- Flush the cooling system and fit a new thermostat and radiator cap.
- Check every connector, especially on swaps with adapter harnesses.
- Fill with good quality oil to the correct level.
With the right parts ready, a workshop that knows Hondas can fit a Honda B18C engine for sale in a weekend.
First Start and Break-In
Crank the engine with the fuel pump relay off for a few seconds to build oil pressure, then start it and let it idle. Check for leaks, bring it to temperature and bleed the cooling system. Check the timing with a light if it has a distributor.
Keep the revs moderate on your new Honda B18C engine for sale for the first few hundred miles and save the VTEC pulls for later. Change the oil and filter at around 500 to 1,000 miles.
Looking After Your B18C
- Check the oil level every week or two. A revvy engine likes to use a little.
- Always warm it up fully before using high revs.
- Check and adjust the valve clearance at the intervals Honda recommends. The B18C uses screw adjusters.
- Change the timing belt on time.
- Keep the cooling system healthy, especially on track days.
Treat a Honda B18C engine for sale from us like that and it will keep screaming to redline for years.
A Few Tuning Notes
The B18C responds well to simple changes: a good intake, a header and exhaust, and a proper tune. Individual throttle bodies and cam upgrades are popular on track cars. Some people add a turbo at moderate boost on the stock internals, but that needs a careful tune and a healthy engine to start with. Whatever you plan, start with a tested Honda B18C engine for sale, not someone else’s problem.
B18C vs B16A vs K20A: Which Should You Buy?
This question comes up all the time, so here is the plain answer.
B16A. The 1.6 litre VTEC engine. Lighter on the wallet and revs just as hard, but it has noticeably less torque than the B18C. Fine for a light CR-X, a bit flat in a heavier Civic.
B18C. The sweet spot for many B-series cars. More torque than the B16A, a big VTEC kick and the same basic mounts and gearbox family. If your car was built for B-series parts, a Honda B18C engine for sale is usually the most sensible upgrade.
K20A. The newer engine with i-VTEC, a timing chain and more power. It is a great engine, but swapping it into an older Civic or Integra needs different mounts, a different gearbox, different wiring and more fabrication. We sell the Honda K20A too, and we will happily talk you through which one suits your budget.
Short version: if you want a proven, simpler swap with a huge parts market behind it, the B18C still makes a lot of sense.
Notes for Integra Restorations
Clean, original Integra GS-Rs and Type Rs have become collectible, and many owners want a matching engine rather than any 1.8. If originality matters, tell us the exact version your car left the factory with. We will look for the right Honda B18C engine for sale, keep the original-style intake and covers where we can, and photograph everything so you can judge it before you buy. For Type R cars, ask us about stock before you commit, as good examples do not stay around long.
Signs Your B18C Needs Replacing
- Low compression on one or more cylinders that a valve adjustment does not fix
- Heavy blue smoke and oil use from worn rings
- A bottom end knock after a missed shift or oil starvation
- Bent valves from a snapped timing belt
- Coolant in the oil after overheating
Send us the symptoms and we will tell you straight whether a Honda B18C engine for sale is the answer or whether a head job or a refresh would do.
Choosing a Gearbox to Go With It
The gearbox makes a bigger difference to how a B18C feels than most people expect. GS-R and SiR boxes have closer ratios than the standard Civic gearboxes, which keeps the engine in VTEC more of the time. Type R boxes are closer again and many came with a limited slip differential, which helps a front-wheel drive car put the power down out of corners. If your current gearbox grinds, pops out of gear or has a worn diff, it is worth pairing a better box with your Honda B18C engine for sale. Ask us and we will quote the engine and gearbox together, with the clutch if you need it, so the whole drivetrain goes in at once.
