The 2JR Engine is a fully built, complete engine package tailored for the (02-06) QR25DE platform, suitable for both street performance and dedicated race use. This long block assembly boasts a balanced and blueprinted foundation, incorporating a Darton fully sleeved block option capable of supporting up to 800whp. The cylinder head is meticulously machined with a 5-angle valve job and fitted with new OEM valve seals. Engine internals offer a range of choices, including 2JRacing H-beam or I-beam forged rod sets, and various piston options such as OEM Cast Turbo (9.5-1 compression), JE Forged (10.8-1 compression), or Wiseco Forged (high or low compression). The build is further enhanced with ARP rod bolts, ARP head bolts, and ACL main and rod bearings. Essential components like a new OEM front cover with an oil pump, a new water pump, and a JWT BSR Kit for complete timing equipment are included. All new OEM seals, gaskets, O-rings, and plugs ensure a leak-free and reliable assembly, complemented by new OEM cam and crank sensors and NGK LFR6A-11 spark plugs. This engine is ready for installation or can be professionally installed by 2J Racing, which includes removal of the old engine and transfer of accessories.
