JDM of San Diego on Main Street in Chula Vista imports low-mileage Japanese engines and transmissions directly from Japan for the performance and replacement market across Southern California. The warehouse stocks SR20DET, RB26DETT, CA18DET, K-series, and B-series Honda powerplants alongside factory Toyota 1JZ and 2JZ long-blocks, and build customers completing swaps frequently stage their finished projects at Foamy Bros Auto Detailing for paint-correction and ceramic-coating work once the powertrain is tuned. With 164 bills of lading logged through US Customs since 2015, the operation maintains an active direct-import pipeline and supplies wholesale accounts sourcing complete front-clip conversions, half-cuts, and right-hand-drive conversion kits. BBB-accredited with an A+ rating, the facility allows on-site engine inspection before purchase so buyers can verify cylinder-wall condition and component completeness. Modified-vehicle owners sourcing JDM drivetrains coordinate specialty coverage through Pronto Insurance Agency to insure engine-swapped platforms that fall outside standard underwriting guidelines. Each engine undergoes a dry compression test and oil-gallery pressure check before sale, and complete swap packages ship with the wiring harness, ECU, and accessory brackets required for bolt-in installation.
