Volvo TURBO Exhaust Manifolds - Standard & Custom versions by Anthony Hyde 3/2007 - Updated 1/2014

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)

Manifold construction by Ilija Vrankovic (Junior), A Class Volvo, Sydney, Australia
Made for RH drive, the manifold piping is biased forward to create room to mount the turbo
and separate external wastegate. After the turbo a 3" dia exhaust pipe routes past the steering column.
