Volvo Turbo Manifold - NEWER Tubular design 1990 onward. Claimed +10 hp gain over older version - Suits Mitsubishi TD turbos as it has a round recess STEP. The manifold can be prone to cracks at the rear where the 4 ports intersect. To fit a Garrett TB03, the flange requires machining out to match turbo and the flange mount face made flat. If fitting a larger heavier turbo / manifold that sits further outward, re- tap cylinder head stud holes from M8 to M10.

Unusual crack point on the cast iron newer style cast tubular manifold (overheated & cracked as fuel mixture was too lean under boost)

Older 'log style manifold', Suits Garrett TB03	Volvo - Older style, Rear. Note screw port for oxygen sensor at bottom - M18x1.5.
