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. |

You can go that way or just use what all the type 4 racecars i have seen (and have built on my own) use which is an accusump.

(IMG:style_emoticons/default/agree.gif) Converting a wet sump to a dry sump is always a PITA. How to drive the pump? Where to mount the pump? Where to mount the oil tank (at least that one is easy) (IMG:style_emoticons/default/biggrin.gif) End up with external plumbing lines and leak sources - ugh! If I recall Hoffman Automotive Machine (HAM) or maybe Jake Raby did a dry sump on a 914 race car long ago. I can’t remember the details but my recollection of seeing it was that it was a lot of work for little gain. Can’t seem to find it though? Anyone else remember who did it? If you just want a constant oil pressure - to solve oil pickup problems - Accusump is the go-to solution. Here’s a lead for you http://www.914world.com/bbs2/index.php?showtopic=57858 |
