as long as you don't have the oil cooler in front like 04 + E55's.. and the bolt pattern is the same as the E55...since the HE bolts on to your bumper frame. After thinking about it closer,theres no way it will work.The Sl55 has the upright HE that is flat against the radiator,also the factory oil cooler is alot bigger than the 55's and its sits on an angle in front of the lower section of the radiator..

I originally did angled tanks on the C32, but there was no difference over the square tank with the size of ours. Most of the fluid is in the passages, not the end tanks, which is where we want it to be.

Any thoughts on the integrated oil cooler? There is plenty of room to move the unit. If it will clear, then I will not bother, unless people are interested.

i'd watch out about the combocooler. Having lower temp coolant and higher temp TOC (as much as 30-40C swings) can cause some thermo-cycling issues at the tube/header locations. All aluminum tanks will thermally deform more than Plastic tanks, and with the TOC tubes expanding more, and CAC tubes less, you may get some issues. it probably wont show up in initial testing, but either do some OEM validation tests or FEA to see this issues.

have experience in this - PM me if you want to know details.
