What heat shield is that above? Would love to know where to source one... Great thread! Also, with the IACV that you installed, did it come with a gasket? Or did you re-use the old gasket from your old IACV? I am having issues with my idle on cold start, when you installed the new IACV, what did you need to do to settle down the rpm from 3000 down to 850?

Yep. 
Haven't had much time to update, especially right now. Work has been crazy busy (make sure you are extra nice to your UPS driver right now... we don't see our families much until February).
GSC S1s went in a few weeks back. PCV side Radium Auto catch can went in and is working. Checked it yesterday and it needs emptied. Intake side has been dry for months. I'm building a better boost leak tester and ordered a different set of plugs. Car is strong but might be getting some spark break up on occasion.
Injectors and suspension are next on the list. Slowly working on my intake manifold before sending it in with a throttle body for porting. I want to do the 84mm FP cover and a 4 inch velocity stack intake with SD this next year. Going to try to push as much as I can out of the IX turbo.
For those that have asked, the exhaust manifold cover was off eBay. You can get whatever you want stenciled in there, but I just like what it said in the stock photo. I have gold reflective tape on the back and my exhaust manifold is Swain coated. Underhood temps seem better than before, honestly.

Really interested in the process you followed for settling down your rpm when you installed your new IACV. Could you give us a really quick run down on what was needed to be done? I do not have evoscan etc so unsure if I should attempt to install a new IACV myself without it...

This is a very positive, inspirational, motivating thread !!
The power of persistence, and you have overcome every obstacle so far.

My hat is off to you...

You want updates? We got updates!
Car is running pretty dang nice right now.
Purchased these from a fellow board member. Thanks for the killer deal! MR Bilsteins and Race Comp Engineering springs.
I wish it were a little lower, but I'm overall very happy with the setup.
Cleaner pic:
Took it in for alignment and ended up having to replace a toe adjustment bolt and both Whiteline tie rod ends. Expensive trip to Firestone, but the handling is amazing.
Got this for Christmas. Nice little improvement in sound quality. Direct plug and play with Alpine head units. I'll probably get some new speakers soon.
Still ironing out the tune since the cams went in. Virtual Dyno had me at 356 the other night in 3rd gear at 98% IDC. I really don't want to spend money on new injectors, but I know that's my next choking point.

Well, I emptied my catch can this weekend and decided to inspect my timing belt (as I'm coming up on 60k with it). Seeing some cracks. Ordered a new Gates blue belt, tensioner, and pulleys. Also ordered a few odds and ends that I needed and a new set of plugs. Car is getting all that done next weekend.
I've been playing with my tune and haven't been happy with the progress I'm making. I upped the boost a tad and can't seem to run more than 4 degrees of timing at 5-6000 rpm (270s on load). Either I've run out of steam on the stock turbo or I have a boost leak. Going to check all that out, soon, but I'm going to take it really easy on the car until I get the timing belt changed.

Turbine Housing
100 3708
Not only did my housing crack, a chunk came out and went through the turbine. Now the turbo used no oil, made no weird noises, but it would not make expected power. This is one of the downsides with the stock turbo and the known issue of that divider cracking.

Yikes. That's not good.
The divider was fine when I installed it after having the housing ported. I was considering a 71HTA later this year as a drop-in. I guess I might need to check the housing out again soon.
Now, my last VD was making right at 350 before I started trying to add boost. So, it's making power, I just thought I'd be able to push for a little more since I've added cams.

I am kicking myself in the *** for selling the HTA 71 CHRA I had bought but never put in, I have heard that is a great power adder for the money. Unfortunately I got hooked on dirt oval racing and every cent and spare minute of time has gone into my sportsman modified. Get the HTA71 in there and hit the rollers!
