Block reinforcement
The B-series is an open-deck block. EPOXY54 fills the top 3/4" of the water jacket for closed-deck strength without machining or sleeves, and coolant still flows underneath. Do it first. It's block insurance for everything after.

Head and main studs
ARP studs clamp the head and mains harder than factory bolts. Match the kit to your exact engine code.
Pistons and rods
81.0 mm is the stock B18C bore; 81.5 mm is a 0.5 mm overbore. Dished turbo pistons lower compression for boost. Rod length differs between VTEC and non-VTEC engines, so check yours.
Bearings
Fresh rod bearings are cheap insurance. Measure clearances and pick the size.
Head gasket and valvetrain
An MLS head gasket seals under boost. Stiffer springs and boost cams suit a turbo B-series.
Fuel
Bigger injectors, a higher-flow rail and an in-tank pump to match your power and fuel.
Oil and cooling
A stronger oil pump and a bigger radiator keep a boosted B-series happy.
Clutch and mounts
Hold the torque and keep the engine planted.
