Do the twin scroll (gen 4/5) sumps fit the gen 1 block?

Recommended Posts

As in the title, I'm thinking of fitting the gen 4 or 5 (or maybe gen 4 then gen 5 depending on how dumb my plans get) manifolds to my early closed deck block.

 

Partsouq images say the sump is a very similar shape but the oil pickup mounts differently, but those are just drawings and not photos.

 

Has anyone put either sump on an early block before?

Yes sump fits, need oil pick up, wind age tray & dipstick from the twin scroll sump as well.

So will the oil pickup fit my block? The pictures (drawings, not photos) imply they mount 90 degrees out. I don't I know if that's bad drawings or my oil pump is different to the phase 2 motors

Mount/flange is the same but pickup different to suit the twin scroll sump. Mines a closed deck block (phase 1) with twin scroll sump, pick up etc. Partners bg5 also has twin scroll sump set up on original engine.

Bl/BP, the first twin scroll legacy, 03+. Gen 5 is the next shape, and they had low mount turbos
