The ARP main stud kit for the B18A1 and B18B1 covers every 90-01 Integra RS, LS, GS, and Special Edition, and it belongs in every serious LS-VTEC plan.\u003c\/p\u003e\n\u003ch3\u003eWhat It Is and Why It Works\u003c\/h3\u003e\n\u003cp\u003eMain caps move under load, and cap walk chews bearings. Studs clamp the caps harder and more consistently than the stock bolts because the stud stretches on a single axis while the 12-point nut is torqued, so your torque wrench reading reflects true clamp load. The block threads also last longer since nothing rotates in them under load, which matters on a block that has been apart before or will be again. ARP machines the studs from 8740 chromoly heat treated to 200,000 psi with threads rolled after heat treat, and the kit includes 10 studs for the 2-bolt main B-series block, nuts, hardened parallel ground washers, and ARP assembly lubricant.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpec\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003e8740 chromoly, heat treated to 200,000 psi per ARP\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConfiguration\u003c\/td\u003e\n\u003ctd\u003e2-bolt main\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplication\u003c\/td\u003e\n\u003ctd\u003eHonda\/Acura B18A1, B18B1 (non-VTEC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSocket sizes\u003c\/td\u003e\n\u003ctd\u003e1\/2 inch 12-point nut, 3\/16 inch Allen (stud)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIncludes\u003c\/td\u003e\n\u003ctd\u003e10 main studs, 12-point nuts, hardened parallel ground washers, ARP assembly lubricant, instructions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMachining note\u003c\/td\u003e\n\u003ctd\u003eAlign hone of the main bores may be necessary after installation (per ARP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eYear\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eMake\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eTrim\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1990-1993\u003c\/td\u003e\n\u003ctd\u003eAcura\u003c\/td\u003e\n\u003ctd\u003eIntegra\u003c\/td\u003e\n\u003ctd\u003eRS, LS, GS\u003c\/td\u003e\n\u003ctd\u003eB18A1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1994-2001\u003c\/td\u003e\n\u003ctd\u003eAcura\u003c\/td\u003e\n\u003ctd\u003eIntegra\u003c\/td\u003e\n\u003ctd\u003eRS, LS, GS, SE\u003c\/td\u003e\n\u003ctd\u003eB18B1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003eCovers the non-VTEC 1.8L Integra bottom end, which is also the foundation of most LS-VTEC builds.

ARP notes an align hone of the main bores may be necessary after installing studs, because the higher clamp load can distort the bores compared to the factory bolts. Do this on a bare block with the caps torqued, verify bore size and alignment, then assemble. On an LS-VTEC or B20-VTEC build these go in alongside ARP 8mm rod bolts (208-6001) as the standard bottom end fastener package. Building a B20 block, several catalogs list this same kit for the B20B and B20Z since the bottom end shares the LS architecture, but confirm against your block before ordering. If the engine is staying a stock-rpm daily LS, the factory bolts are fine and your money is better spent elsewhere.\u003c\/p\u003e\n\u003c\/li\u003e\n\n \n\u003cli id=\"VehicleFitment\"\u003e\n \u003ch3\u003eFitment\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eYear\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eMake\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eTrim\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1990-1993\u003c\/td\u003e\n\u003ctd\u003eAcura\u003c\/td\u003e\n\u003ctd\u003eIntegra\u003c\/td\u003e\n\u003ctd\u003eRS, LS, GS\u003c\/td\u003e\n\u003ctd\u003eB18A1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1994-2001\u003c\/td\u003e\n\u003ctd\u003eAcura\u003c\/td\u003e\n\u003ctd\u003eIntegra\u003c\/td\u003e\n\u003ctd\u003eRS, LS, GS, SE\u003c\/td\u003e\n\u003ctd\u003eB18B1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003eCovers the non-VTEC 1.8L Integra bottom end, which is also the foundation of most LS-VTEC builds.
