Subaru Engine Replacement - Supply & Fit Available UK-Wide

A reconditioned Subaru engine typically costs £2,200-£4,800 depending on code (EJ25, FB25, FA20), with performance rebuilds (EJ257, FA20F) ranging £3,800-£7,500. Supply-only fitting adds £600-£1,500 labour, while main dealers charge 40-60% more. For budget options, used engines start around £800 but carry higher risk. *Always compare three quotes before committing - prices vary significantly by supplier and engine condition.*

Four key factors drive pricing: engine code (EJ25 vs EJ257), condition (used vs reconditioned vs rebuilt), vehicle complexity (STI or H6 models cost more), and supply-only vs supply-and-fit. Location matters too - London and Southeast labour rates run 20-30% higher. Our comparison tool shows transparent, itemised quotes so you see exactly what you're paying for.

In most cases, yes - especially if the chassis, gearbox and AWD system are solid. A rebuilt Subaru engine with upgraded components (e.g., MLS head gaskets on EJ25, uprated crank on EE20) often outlasts the original. If your Forester or Outback holds £3,000-£8,000 value, replacement is almost always more economical than buying another vehicle.

Supply-and-fit covers sourcing your exact engine code, removing the old unit, installing the replacement with new fluids/filters, workmanship warranty, safe disposal of the old engine, and a post-fit test-drive. Labour typically adds £600-£1,500 depending on model complexity. *Always confirm whether VAT, delivery and ECU reset are included in your quote.*

Common models like Forester or Impreza with EJ25/FB25 engines typically take 3-5 working days for a like-for-like swap. Complex builds (STI EJ257, H6 EZ36, e-BOXER hybrids) may require 5-7 days. The biggest variable is engine availability - our network stocks commonly replaced codes to minimise wait times. *Ask suppliers about current lead times before booking.*

Yes - every reconditioned Subaru engine supplied through EngineMarket includes a minimum 12-month unlimited mileage warranty. Extended 24-month coverage is often available on fully rebuilt or remanufactured units. Warranty covers major internals: crankshaft, pistons, timing components, oil pump and cylinder heads. *Always confirm exact terms directly with your chosen supplier before purchase.*

Used engines (£800-£2,500) offer lower upfront cost and suit temporary fixes or imminent resale. Reconditioned units (£2,200-£4,800) include new gaskets, bearings and seals, plus warranty protection and should deliver another 100k+ miles. For failure-prone engines like EJ25 (head gasket) or EE20 (crankshaft), a reconditioned unit with upgraded components is strongly recommended for long-term reliability.

EngineMarket connects you with a UK-wide network of vetted Subaru specialists, including recognised hubs in the Midlands, Northwest and Southeast. Our registration lookup instantly matches you with nearby suppliers who stock your specific engine code and offer fitting. Nationwide delivery is available if no local specialist holds your required unit.

The four most catastrophic failures driving replacement are: EJ25 head gasket failure (1999-2011 NA 2.5L Forester/Outback), EE20 boxer diesel crankshaft fracture (2008-2016), EJ257 piston ringland/rod bearing failure (STI turbo), and FA20 valve spring recall/timing tensioner wear (BRZ/WRX). Early detection rarely prevents these from becoming terminal - replacement is usually the most reliable solution.

Compare multiple quotes - prices for the same EJ25 or FB25 code can vary by £1,000+ across suppliers. Consider used for tight budgets, but choose reconditioned with upgraded parts for long-term ownership. Ask about supply-only if you have a trusted garage, and always verify whether fitting, delivery and VAT are included. *Our free comparison tool does the legwork so you don't miss hidden savings.*
