OK, so now I've got the mod bug for the '97 Mounty. While I am considering a remote turbo install for the Mounty (and that comes with about 20 years of painful Saab turbo experience), I do have one question. I did a search on this one, but didn't find anything concrete:
Are there any significant downsides to relocating the oil filter (actually, I'm considering a dual filter option) to the rear of the Mounty via an adapter and relocation kit? The reason that I'm asking is that for a oil/water turbo, there's already lines running back and forth from the front to the rear in doing a remote turbo install. Squires has done that well, but I see a lot of their applications indicate a need for the remote oil pump, but nothing isolated for the water circulation issues.
Do you think the reason for the remote oil pump is because some of the turbos are gravity fed for their oil?
I'm thinking that if I relocate the filter to the back and add in a loop to include the turbo oil line, I might be OK.
On the other hand, because of the extra couple of quarts of oil need for the extra long lines and a couple of filters - plus the push into a smaller oil line linked via a banjo bolt into a turbo - the restrictions here may impact the overall oil pump performance from the front of the Mounty.
Now, as I recall hydraulics from college, the leading pressure prior to the restrictions (i.e., read one extra filter in a dual filter set-up, extra weight of the extra oil in the links and one of the filters, and a restriction to a smaller oil line to feed the turbo) would inherently increase the front loaded line pressure - with a peak building at the junction of the smaller oil line running to the turbo. Pressure would be inherently LESS after the turbo when the smaller outlet -- and this is the line that will eventually feed back to the original oil filter location which now has an adapter in it's place.
Now, if most oil banjo bolts are in the 12mm/14mm/16mm range, that's about the same size of the 1/2" inside diameter oil lines that would run in the majority of the remote oil filter relocation - so my restrictions may be minimal at best.
I've read other items regarding the remote turbo install for V8's - and most have the remote oil pump - and none had a remote oil filter relocated to the rear to take advantage of the existing oil line pressure readily available in this type of set-up.
If anyone has thoughts on this, I'm open... In fact, open enough just to take STS's proven deployment and plop it in without much more thought on this subject.
