Putting together a Type IV dry sump system Options

[Flat6forlife]

Hey everyone,

I'm a few weeks away from dropping the drivetrain from my '73 1.7 for a refresh/rebuild. It's an IDF-carbed 2.4L (supposedly, I haven't cracked it open yet) that'll be used mostly for street driving but will see regular autocrosses and occasional track time, hence the dry sump. I've researched for a while and have a decent plan, but I'd love some insight from those who've put them together.

As it stands, the current plan is as follows:
914/6 oil tank with the attached filter
CB or Thorsten Pieper pump (I'd like to retain the OE fan)
Tangerine Racing Oil Cooler and Thermostat setup with the fan
Requisite braided AN lines with appropriate hardware

I see that CSP also makes a pump, but I can't find anyone who has experience with them. The TP pump seems like the best way to go, but the only dry-sumped racer I've seen used the CB to much success. Money isn't an issue for the TP pump; I'll pay for the extra protection and/or simpler installation. The CB needs modification if I've read correctly. Does anyone have a preference?

Also, using the 914/6 tank and its attached filter makes the original filter redundant. Should I run the LN oil filter block-off plate or use a filter relocation adapter to feed an oil cooler (with an inline thermostat) and leave the factory oil cooler in place for two coolers? Maybe double oil filters and the Tangerine oil cooler kit?

I appreciate the insight/assistance! Also, if this has been beaten and covered to death anywhere else, please link it. I'm happy to read and learn that way.

Accusump will keep the pressure up in a pinch but a big advantage to a dry sump is less drag from the sump oil getting up into the crank and much cooler and less foamy oil. This means you can run thinner oil for less friction as well.

I think to do it on a typeIV you would need to replace the stock oil filter with a can that just u-turns the oil right back into the engine. Cooler should go on the return line from the engine to the tank.

It might be possible to use the stock oil pump for the high pressure work if you could get a tube to it from the external oil tank and just have a belt driven scavenge pump. Check out used NASCAR dry sump parts on Ebay. THere's a lot to choose from if you are on a budget.
