911/83 2.9 RSR spec engine value

[Rikard]

HI guys

I recently bought 72T built in to a RSR tribute with a very special engine. It has the 911/83 engine in it from the rest of the world Carrera (same as 73RS) with the magnesium case and the following spec:
Andial/Mahle 2.9 10.5 to 1 Pistons
Twin plug heads
Patrick Motorsport twin plug distributor with full twin MSD
Throttle body MFI with long thrumpets and Kugelfisher pump seems to be the same as the one from the SCRS
I am yet to find out exactly what cams and crank is in it, car is still in transit to Florida from Europe.
So the big question is, what is an engine like this worth?


It has only done 150 km but was run in on a bench prior to installation.
Here are some pics (throttle bodies have covers for storage)

Looks like a period correct motor which is important for certain vintage racing groups .The Andial P & C are 94 mm and the cylinderwalls are thin in the 2.7 case.The rotary Kugelfisher pumps are as rare as the stacks.If it has the lightweight RSR crank value would be $35-45,000.Probably could not build it for that money.Downside it is not a longlife combination but still cool.Red Stacks rule.Fred

Thanks Fred 👍 The pistons are 93 mm so should be a little less bad lol . I actually heard that the Andial PC did not have the same issues. When the car gets here I will see exactly what it has, run it for a while and then get it on the dyno. Yes, kugelfisher is rear since Porsche only made about 20 SCRS. Saw one for sale for 20K the other day 😲
