I'm looking to build a bolt on scavenge pump for an SR20DET with either a p11 or GTiR oil pump gearset as the pumping mechanism. I'm starting my first year of mechanical engineering so once I learn a bit of the basics I should be able to make something fairly easily.

The plan is to have a bolt on piece that sits right where the ac compressor would sit normally. Since I'm sure many of your swapped cars don't have ac compressors I doubt it'll be an issue. I'm also planning on making them stackable. So once I get my design down and working correctly I may start having someone manufacture these, so you may be able to buy a relatively cheap dry sump pump made from factory gearsets within the next 2 years.

I'm doing this because my sr20det is going in a lotus 7 "kit car" I'm building from scratch and since the SR is such a tall fucking engine I need to drop around 3 inches from the bottom of the pan, my plan is to make a semi-dry sump. Using the factory pump as the pressure pump and a GTiR based scavenge pump to scavenge the "pan" into the aerator/holding tank. From the Oil tank it would go through a ball valve (to stop oil flow when shut-off) and down to a welded on fitting on the upper pan which would be directly connected via a metal tube with 2 AN fittings on it back to the stock pickup. With this setup there should be absolutely no time whatsoever that you should lose oil pressure. Worse comes to worse I can always pull the gears out of the stock pump and stack another pump to the scavenge pump as a pressure pump. Either way should work.





I'd like to ask for some help in finding a place to buy some GTiR pump gears, inner and outer, so I can start designing said pump. Worse comes to worse I'll design my own gerotor pump and use that. I would much rather base everything off of the stock pumps though.
