Couldn't figure out what to do with the inlet for the plenum, it originally had a flange on there but the inlet was about 45mm, there wasn't enough meat to cut it out to 2½" inch and still have the flange seal so I decided in the end just to weld a piece of 2½" tube to the inlet, this was a last resort as I was trying to avoid modifying it but it was the only way I could see it was going to work.
Mmm lots of meat to remove.
Also made up this adaptor to go from the 60mm square flange on the exhaust manifold to the 44mm Tial v band. The only steel I could find was either 5mm or 10mm thick and the 5mm was a lot easier as it was 75x5 flat bar and the flange is 75x75, I think it's far enough away from the collector that it won't bend with the heat. I just need something to make the square gasket out of, I've been thinking about trying to use some thin copper sheet, if anybody has any? Last thing I need before putting the manifold on is my new exhaust manifold gaskets that I ordered from Stewart Wilkins in Oz, I told him I wanted them before Christmas but for some reason there was like a week delay before they sent them so there is a pretty good chance I won't get them tomorrow.
