I'm interested in shoehorning a 1988 Esprit 920 engine into my Jensen-Healey. I know the oil pan is too wide for the cross member, however, I understand you modified your sump, do you have any idea if a 920 sump can be modified to fit without changing the chassis of the car?Michael,
The Lotus 920 is just a 2.0 version of the 2.2L 910 Turbo. Whatever fit problem there might be putting one into a J-H will also apply to the other.

The cylinder blocks are dimensionally the same for the 907 and 910/ 920. The 'wide' block's greater width is all in the bolt-on Main Bearing Panel (MBP), and the larger, wide-mouth sump matches the perimeter of the MBP.

How would you have to modify the sump? If you can do it entirely below the MBP, without modifying the MBP, then there's nothing inside the sump that would be diffiuclt to modify it to fit. There is a windage tray that bolts in, but it doesn't involve any hinged panels. See tha attached JPEG
