Extremely nice build with little restorations here and there! And the shed is awesome, I can imagine how nice it is to have your own time-out in there.
About the manifold, it's almost like mine, except I have it on the RB25. Just be careful when fiddling around with injectors. Had some E85 pissing all over the manifold runners from cracked injector o-ring. Needles to say, paint peeled off like candy paper..
Keep up the awesome work, looking forward seeing updates on this build!
