I already posted on a few threads awhile back that when I first started a dunebuggy suby/901 thread that when I got the adapter and stuff from kennedy they also offered a big short suby oil pan. I wanted to make my own but wanted to use their stamping to make it simpler. I used their stamping and top plate and added some sbc cheater swinging gates from speedway motors. I think it came out great. I think I found out about the pan from a thread that showed someone making his own. Don't remember the exact thread. Annnnyway I just bought the parts from kennedy and speedway. Seems like it was less than 100.00 from kennedy and the pan holds about 8 qts and is about 4-5/8 deep with a gate on each wing to keep the oil around the pickup. You can make your own gates out of hinges. I also made a short pickup by unbrazing the original and shortening it and silversoldering it back. I also reinforced it with a additional support to one of the windage tray bolts. This was for the dunebuggy but it will work on the 914 except if you use the small car mount as it won't fit inside the mount.
On suby motors it should be said that the oil pickup to pan clearance should be checked even on stock applications. I found that brand new parts have wide tolerance variations. On a new sti pan and pickup the gap was ony 3/32. I like about 7/16 for high rpm applications. I built my son a 8qt pan for his sti and formed a new bottom to fit inside the equal length perrin headers he was using. It looks like a triangle from the bottom or sorta like texas. It also has gates. When I cut the bottom out, I couldn't get all the ends on one piece to bend up so that left one wing end open and that left a easy way to measure the modded pickup. On this pan I had to add aluminum heat shields to go between the header and the pan. It's all pretty tight.
