No such thing as decent and cheap.

What car is it going into?
What parts do you need?
For intercooler piping, check out http://burnsstainless.com . order tubing and elbows as needed. Cut and weld as necessary. Measure twice, cut once...

If you’ve not worked with this engine before and have to fab to make it fit, I’d stop trying to make it fit and run it on a stand. Rig and weld a temp bench to bolt it on, weight it and you can run the engine there to see if everything is ok.

Also would be good idea to measure compression & do leak-down once you've got it running on stand and fully warmed-up.

And easy enough to pull oil-pan and measure rod-bearing and main clearances. Replace with new bearings while you're there. Heck, might as well pull head and pistons and replace rings too while you're there. Minimal efforts for brand-new engine.
