Dry sump tanks
Anyone want to share what they've done as far as dry sump tanks in a street car? IMO, a dry sump system has a lot going for it in the 20B app. but I'm having a hard time visualizing where to place a 2-3 gallon tank under the hood that can gravity feed the pump.

Why does it have to be gravity fed?
Most racers run it somewhere behind the engine in the passenger compartment. This way you can put the weight where you want it...centered and downlow.
My tank is custom fabricated and fits in and conforms to the spare tire well in my vert. It is a compromise in design but will work just the same in the end. It is also not in an ideal location since it is WAY out back and so far behind the centerline of the rear wheels. However, there is VERY limited room in my car as it is still (somewhat) a street car. With it installed in that location, you do not even know it is there and it's easily accesesible to drain from outside the car with out having to remove the tank.
Here are some old pics of it being made.
There is more baffling in the tank than what is shown.

Most tanks ive seen are in the passanger side floor area. I have my battery box mounted where my old storage bins were, what about making a custom setup placing the battery behind the driver and making a tank to fit being the passanger? That way it would add a similar amount of weight, and not sit to high. It also may protect the tank from colission alittle better

If I get hit from the rear I'll be reaching for the keys to shut down pretty quick.
On any coupe though, I don't really see any reason why your suggestion would not work. Keep in mind though, sump tanks need to be vented.

RX-Heaven: how did you route the feed and return lines? Are they in car or underneath?
In addition to the dry sump system, you should also run an accusump. They're not that much (~$180 at summit), and they pre-lube the engine before start up, as well as keep oil pressures more constant.

The only real benefit with an accusump on a dry sump engine would be the pre-lube abilities. I don't know if it would really do anything to keep oil pressures more constant. Also, it is just one more complication...plumbing, location, wiring (if choosen).

Since then, the manifolds have been shortened but I have not had the car available to test fit again. I was running a 13bt in my vert and sold the 88tII the engine was originally going in...long story....
Is you car up and running these days? Havent seen much of it on the forum?
