Whether it's the B16A2 in a 99-00 Civic Si (EM1), the B16A3 in a del Sol VTEC, or a JDM B16A swap in an EG hatch, the ARP main stud kit is the right way to anchor the crank in a bottom end that will be revved hard or boosted.\u003c\/p\u003e\n\u003ch3\u003eWhat It Is and Why It Works\u003c\/h3\u003e\n\u003cp\u003eMain studs clamp the caps more accurately than bolts. The stud threads into the block hand tight, so when you torque the 12-point nut the fastener stretches on a single axis and the torque reading reflects real clamp load instead of thread friction. The block threads also see less wear, which is worth caring about on a 25 year old aluminum block that may get freshened more than once. ARP machines these studs from 8740 chromoly heat treated to 200,000 psi, thread rolled after heat treat, and the kit covers the B16A's 2-bolt main arrangement with 10 studs, nuts, hardened parallel ground washers, and ARP assembly lubricant in the box.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003ctable\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 B16A1, B16A2, B16A3\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\/table\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\u003e1999-2000\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCivic\u003c\/td\u003e\n\u003ctd\u003eSi\u003c\/td\u003e\n\u003ctd\u003eB16A2 (EM1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1994-1997\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCivic del Sol\u003c\/td\u003e\n\u003ctd\u003eVTEC\u003c\/td\u003e\n\u003ctd\u003eB16A3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003eAlso fits JDM B16A engines commonly swapped into EF, EG, and EK chassis.

ARP notes that an align hone of the main bores may be necessary after installation, because the studs pull the caps down harder than the stock bolts and can distort the bores slightly. Install them on a bare block, torque the caps, and have your machine shop check bore size and alignment before the crank goes in. Skipping that step on a swap-meet block is how guys end up chasing oil pressure. If the block is at the shop anyway, this kit plus rod bolts and bearings is the cheap part of the build. For the B18C VTEC engines use 208-5403 instead, and for the non-VTEC B18A\/B18B use 208-5404.\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\u003e1999-2000\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCivic\u003c\/td\u003e\n\u003ctd\u003eSi\u003c\/td\u003e\n\u003ctd\u003eB16A2 (EM1)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e1994-1997\u003c\/td\u003e\n\u003ctd\u003eHonda\u003c\/td\u003e\n\u003ctd\u003eCivic del Sol\u003c\/td\u003e\n\u003ctd\u003eVTEC\u003c\/td\u003e\n\u003ctd\u003eB16A3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003cp\u003eAlso fits JDM B16A engines commonly swapped into EF, EG, and EK chassis.
