Know This Engine Before You Buy
The research behind our purchase interview — recalls, bulletins and real install economics for this engine family:
A quick look at your own vehicle makes sure the right engine shows up:
- Verify the 6th digit of the 17-digit VIN is '1' (confirms 1.5L Turbo; '2' indicates 2.0L Hybrid which will not fit)
- Verify original engine block is stamped with 'L15BE'
- Confirm understanding that this engine is sold without the turbocharger
What the install really takes — plan and budget with confidence:
Special tools this job needs:
- Engine hoist/crane with a load leveler
- Honda crankshaft pulley holder tool
- Fuel line quick-disconnect tools
- OBD2 diagnostic scan tool with Honda bi-directional capabilities
- Torque wrench
Budget for these consumables at install:
- Fresh full synthetic 0W-20 motor oil (3.7 quarts with filter)
- New OEM Honda oil filter
- Fresh Honda Type 2 Blue Coolant
- New OEM-spec laser iridium spark plugs
- New intake manifold gasket
- New exhaust manifold gasket
- New turbocharger mounting gaskets
- New high-pressure fuel joint pipe (Mandatory replacement)
- New front and rear crankshaft main seals
- New torque-to-yield (TTY) fasteners (harmonic balancer bolt, cylinder head bolts, mount bolts)
What your vehicle’s computers will need after the swap:
What’s involved: Crankshaft Position (CKP) Sensor Relearn / Immobilizer Re-marriage
sources differ: Arm 1 states only a CKP sensor relearn is required if original ECU is retained (no immobilizer re-marriage needed). Arm 2 states an immobilizer re-marriage is required because the ECU must be paired with the immobilizer module. Cautious value 'model_dependent' selected; confirm with us or a professional technician before install.
Pro tips for a smooth first start-up — hand them to whoever does the install:
- Turbocharger Transfer: Must transfer original turbocharger, wastegate actuator, oil feed/return lines, and coolant lines using brand-new OEM gaskets.
- High-Pressure Fuel Joint Pipe: Never reuse the metal high-pressure fuel joint pipe. It is designed to crush-seal once; reusing it will cause a high-pressure fuel leak.
- Fragile Camshaft Position Sensor Harness: Wiring harness connectors and wires near the camshaft position sensors are extremely fragile.
- Torque-to-Yield (TTY) Fasteners: Critical fasteners are designed for one-time use and must be replaced.
- Immobilizer Re-learn / CKP Relearn: Plan for necessary programming before the vehicle can run.
- Grounding Locations: Pay meticulous attention to all engine and transmission ground strap locations.
- Turbo Priming: Ensure the transferred turbocharger is primed with oil before first startup to prevent bearing damage.
Easy to get right once you know them:
- Reusing the High-Pressure Fuel Joint Pipe
- Skipping the CKP Relearn or Immobilizer Programming
- Mismatched Turbo Components (attempting to use a turbo from a 10th-gen Accord or Civic)
- Using Cheap Universal Coolant instead of Honda Type 2 Blue Coolant
- Failing to Prime the Turbocharger
- Reusing Torque-to-Yield (TTY) Bolts
Not issues with the units on this page — the manufacturer documented these for every engine of this family, wherever you buy one. Handy for your installer:
🔎 Recommended at install: Replace high-pressure fuel pump to prevent internal cracking and fuel leaks.

Shipping & Handling
- Ships by LTL freight on a pallet — a real freight truck, not a parcel van
- Your checkout freight quote covers delivery to your door (liftgate service included for residential addresses)
- The carrier calls ahead to schedule a delivery window — someone must be present to receive it
- Typically palletized and picked up within 2–3 business days; transit time depends on distance
120-Day Warranty
This part includes a 120-day warranty.
- If the part fails within the warranty window, we'll replace it or refund per the coverage terms
- Coverage is parts-only — installation labor is not included
- Warranty covers defects — not installation errors, misuse, or damage after installation
Your pre-purchase interview reviews these exact terms with you before anything is charged.
Returns (30 Days)
We accept returns of uninstalled parts within 30 days of delivery for this part.
- Defective parts: We will replace the part or issue a refund at our discretion
- Programming: "Needs to be programmed to my vehicle" is not a valid return reason. Many modules require dealer programming — we're happy to help connect you with resources if your dealer says it's not programmable
- Return shipping: This part ships by freight (LTL) — the part price is refundable per the terms above, but shipping costs are non-refundable and return freight follows the seller's return terms. Your pre-purchase interview walks through the exact numbers before you buy
- Parts must be returned in original packaging and unmodified condition
- Poorly packaged returns that arrive damaged will not be credited
Damaged in Shipping?
Freight damage is rare — and you're fully protected when you do two things at delivery:
- Inspect before you sign — you're allowed time to look the pallet over while the driver waits
- Write any damage on the delivery receipt before signing — that one line is what makes a freight claim succeed
- Severe damage? Refuse the delivery — it goes back at no cost to you and we make it right
- Photograph the pallet before unwrapping; report concealed damage within 24 hours of delivery
We handle the carrier claim — you just help document it. Your pre-purchase interview walks through this checklist too.
Order Cancellation
Cancel before shipment for a full refund. Once the pallet has been built, a preparation charge may apply — and once the freight carrier picks it up, shipping costs are non-refundable and standard return terms apply. Your pre-purchase interview shows the exact numbers before you pay.
