I'm also having problems with finding a decent set of extractors for my 98 SIII Caprice. I'm after a set of extractors for an L67 preferably Pacemakers with 1 3/4in. primaries that collect into 2 1/2in. secondaries with a final collector of 3 6/8in. I am trying to avoid having to get the extractors fabricated.
I have phoned the major extractor makers like Pacemaker, Genie, HM Headers and even Castlemaine Exhaust but no one makes them off the shelf in this size for any VS V6 models. The major extractor makers do make them in this size for VT onwards with Ecotec NA and L67.
It is hard trying to find information to even see if VS V6 extractors for SI and SII will fit onto the SIII Caprices and Statesmans due to the SIII's having a VT engine and box from factory. I suppose the SIII utes would also have the same VT V6 engines as they were made up until 2000 or 2001 until the VU rolled out.
Does anyone know if the VS and VT Ecotec engines and auto's are the same externally or are the differences internal only?
Also does anyone know if VS Ecotec n/aspirated extractors fit onto VS L67 supercharged engines. Are the extractors flanges the same for both engines?
And finally should VS sedan, wagon and ute V6 extractors fit into the Caprice and Statesman as i think that the engine bays and front end dimensions would be the same across the range.
