Prime Motoring Phase 1-X EJ25 Closed Deck Shortblock
You asked for it, we built it! Prime Motoring joined forces with Outfront Motorsports out in California to design engine packages for the EJ25, FA20, and even EJ20 platforms. Each engine is machined & assembled by Outfront Motorsports to our specifications. Each engine is built to what we want based on what we've learned from our experiences in drag racing and from our customers. We wanted to offer engine packages that were not influenced by profit margins and pure sales volume. We wanted something built BY the community FOR the community.
