The putty is POR 2 part putty stuff. The problem was I couldn't weld all the way around the bottom of the runners to the intake flanges because the bolt spacer got in the way, so I tried to putty it. My brother said the POR stuff was great, and he had some left over, so I gave it a shot. The stuff is pretty crappy, so I'll be grinding it off. It claimed it was 'machineable like steel', but its weak as hell. Grinding it off will take 20 minutes. I could probably just hit it with a torch(outdoors of course, I learned my lesson with the galvanized...) and it'd discintigrate.
I'll probably finish cleaning up the ports on the intake flanges then weld them on from the inside. Maybe put a little line of epoxy around the bases just to make it look pretty.
I also have some very good high temp iron based silicon adhesive that I bought for filling my exhaust ports, that stuff will surely do a better job than the POR crap. POR is good for patching cracks in sheetmetal, terrible for any kind of filling or mechanical strength.
I'll be putting on the injector bungs in a few days, thats probably the next thing I'll do. I haven't decided where I'm going to mount the injectors. Either on top of the runners, or on the inside, over the valley. I'd have to angle the injectors towards the back of the motor to fit them. Rails will be individual 'caps' mounted on each injector with an aluminum fuel lines combining into two lines, tri-y style. Those lines will go to my fuel pressure reg. Thats my preferred method. Injector is firing towards the port, rather than across it. It'd probably help low end, which is what I'm concerned with building power at. I'm trying for peak torque if the engine were N/A to occur at around 2750-3000rpm. Simply because I read in a book, either Turbochargers by Hugh Macinnes or Maximum Boost by Corky Bell that you should shoot for max N/A torque at where you want the turbos to spool. Makes sense to me.
Throttle body is either a '02 or '04 Cobra BBK throttle body, twin 62mm plates. BBK really needs better quality control. But I got it for $125 so I can't complain, it'll work.
I was using galvanized because I was lazy.. Needed some 16guage exhaust tubing, it was late so the only place that was open was Autozone, so I just used a couple of their 18" long 2.5" dia exhaust pipe. This is the first time I welded it in a closed garage, I only welded a little bit, just patching/finishing.
