I need one elbow for Skyline twin blowa. I'm fitting it to an S13 it fits on a five stud pattern but different spacing to S13/14 don't know about 14a/15. I think the single turbo uses six stud fitting.Maybe I'd be better getting flange made up for my elbow think I'm out on my own with this one as I've searched the forums and on SXOC. The turbo is a Garrett TE27D1 part no is 466071-2. After market elbow preffered as I'm going to use a polished turd. Sorry an XS Pooher cheers. Oh yeah that bonnet posted on SRB's ad for S14 isn't on my car but I did toy with the Idea as my bonnets horrible so thanks for input on that.
