1.9L 16v - B4194T 

The B4194T is the 1.9 turbocharged four-cylinder Volvo fitted to the S40 and V40 T4 among others. This page covers its two key components, the ones that take the boost pressure. WISECO forged pistons are offered in 81mm at an 8.5:1 compression ratio, with several oversizes available up to 82mm. ZRP forged connecting rods come with their ARP2000 bolts, the only fastener that holds the required clamp load on a rod worked in tension at high revs. One point to read before ordering: the rod kit designation carries the B4204T and B4194 codes rather than B4194T alone.
