One of our fearless members had a problem with oil starvation at a track day earlier this year. (2.3L Ranger engine). The result was a spun bearing.
He's replacing the engine with a 2.3L Focus motor.
The Focus motor comes with a balance shaft setup which is easily removed with parts from Cosworth.
It turns out the oil pumps are different too, causing some interference with the the earlier version of the sump. The early sump was apparenly made by Titan but sold by Raceline.
Installing a Ranger oil pump into the Focus engine seems to work fine, it measured the same and fits. Testing will tell.
We also heard rumors that Raceline changed the sump design slightly.
I called Raceline and they confirmed the changes, also that an upgrade is fairly easy but you may need a new baffle tray and crankscraper. Possibly a dipstick upgrade too. Some minor machining of the old sump may be required.
The photos below show the early and late sump for the 2.3L I don't know the details of the 2.0L.
Raceline say this early sump was one of the first 10 made.
You can see the added baffles in the late sump. We'll make some sheet metal baffles for the older sump.
Other differences are - the oil pickup point is deeper in the newer sumps and a threaded connector for the dipstick. If your dipstick is leaking it can be retrofitted.
We don't know if the oil starvation problem was because of the early sump design or just low on oil. Perhaps the leaking dipstick???
There are differences between Raceline sumps depending on which engine it is for. 2.0L & 2.3L Focus and 2.3L Ranger.
If you are building a Duratec with the Raceline wetsump - call them first to be sure you get the right one.
