Years ago when I was working with 3SI cars, my friend Matt bought one of those AFPR's.
They're complete garbage... they weren't adjustable in the least.
The rest of the kit look okay, except that's a Greddy (replica) exhaust manifold... which will require some modification to work.
I have one of them, and in my case the first runner hung high enough so I didn't have to cut it off. (didn't hit the oil filter housing)
However the WG flange is backwards... you'll need to cut it off and rotate it, or do what I did and make an identical flange, and welded it back on the manifold at a rotation of 90 degrees.
