ARP Honda/Acura 2.0L (B20A5) Head Stud Kit 1990-1993 Acura Integra
ARP Head Stud Kit 208-4703 replaces OEM torque-to-yield bolts on Honda/Acura 2.0L B20A5 engines in 1990-1993 Acura Integra LS and RS models. These studs provide consistent clamping load to maintain head gasket seal under extreme pressures from turbocharging or high compression ratios. Engine builders rely on this kit for durable performance in demanding applications.
Key Features
- ARP2000 Alloy Studs: Forged from proprietary material rated at 220,000 psi tensile strength to handle high boost and nitrous setups without stretching or fatigue.
- 12-Point Chromoly Nuts: Heat-treated for 200,000 psi strength allowing precise torquing with standard 12mm socket and reduced chance of rounding.
- Hardened Steel Washers: Parallel ground design evenly distributes load across head to prevent distortion and ensure gasket integrity.
- ARP Ultra-Torque Lubricant: Included tube provides friction-consistent application for accurate torque values during installation.
- Complete 10-Piece Kit: Includes M10 x 1.25 studs at 5.75 inches long for direct bolt-on fit with stock or aftermarket cylinder heads.
Product Notes
- Studs are reusable allowing multiple engine teardowns without replacement.
- Inspect threads and apply fresh lubricant each reinstallation for best results.
- Packaged in protective ARP box to prevent damage during transit.
Installation Notes
- Professional installation recommended.
- Torque in sequence to ARP specs starting at 30 ft-lbs then 60-65 ft-lbs using moly or ARP lube.
- Compatible with OEM multi-layer steel head gaskets and most aftermarket options.

Frequently Asked Questions
-
Q: Will this kit fit B18 or B16 engines in Integra or Civic?
A: No this kit is specifically for B20A5 engines ARP offers separate kits like 208-4605 for B18 and 208-4301 for B16. -
Q: What alloy are these studs made from and what is the strength rating?
A: Constructed from ARP2000 alloy with 220,000 psi tensile strength and 74,000 psi yield for superior load handling over steel bolts. -
Q: What torque specs and sequence should I use for installation?
A: Use ARP lube torque to 65 ft-lbs in three stages following the factory head bolt sequence printed on most head gaskets.

ARP
ARP (Automotive Racing Products) is the world’s premier manufacturer of high-strength engine and driveline fasteners—head studs and bolts, main studs, rod bolts, and more—engineered and manufactured in-house from start to finish for race-proven reliability. With vertically integrated processes that include cold heading, machining, heat-treating, thread rolling after heat treat, and rigorous QA, ARP maintains aerospace-level certifications (ISO 9001 and AS9100) and validates every part for repeatable clamp load and fatigue resistance. Signature alloys such as 8740 chromoly, ARP2000, L19, and Custom Age 625+ deliver ultimate tensile strengths up to the super-alloy range, while ARP Ultra-Torque fastener assembly lubricant helps achieve consistent pre-load during installation. From street performance builds to professional motorsport programs, ARP fasteners provide precise fitment, superior metallurgy, and the durability needed to keep engines together at elevated cylinder pressures and...

ARP Head Studs
ARP head studs replace factory head bolts with precision-machined threaded studs that provide more consistent and repeatable clamping force on the cylinder head gasket. Unlike head bolts that apply torque through both rotational and tensile forces, head studs allow the nut to be torqued concentrically on a stud that is already stationary, producing more even clamping load across the entire head gasket surface. Popular ARP Head Stud Applications ARP head studs are available for a wide range of performance and turbocharged engines including the Subaru EJ series, Honda K series and B series, Mitsubishi 4G63 and 4B11, Honda Civic and Integra, Toyota 2JZ-GTE, Nissan SR20DET and RB series, GM LS series, Ford Coyote and 5.0, and Dodge/Chrysler HEMI applications. ARP offers both 8740 chromoly and ARP2000 alloy head stud kits, with the ARP2000 material providing approximately 20 percent higher tensile strength for high-boost applications above 30 psi. Why are head studs preferred over head b...
