Frequently Asked Questions
What is a Subaru long block?
A long block is the short block (block, crank, rods, pistons) plus the cylinder heads and valvetrain, assembled and ready to install. A short block is the bottom end only.
Do I need to send a core?
No. Every Crawford long block is built on a brand-new OEM short block. Pricing includes reconditioning and reusing your existing heads; new OEM heads can be added at checkout.
Which cars do they fit?
The EJ255/EJ257 long block fits the 2004–2021 WRX STI, 2002–2014 WRX, and the EJ-powered Forester XT, Legacy GT and Outback XT. FA20 (BRZ / FR-S / 86 and WRX DIT) builds are handled as short blocks plus head work; contact us for a quote.
Are they forged?
Yes. Every rating uses CrawfordSPEC forged pistons; Club Racer and Racer Spec add billet rods. See each product page for the exact components.
Can I customize the build?
Every long block is built to order. Pick the power rating that matches your goal, and call us if you have a specific combination in mind.
