Nice. I'd imagine it is nice to drive and the power on the freeway is good?
Any notable concerns or issues? Can someone with a 150,000 mile rig slap a kit on and be OK? What would you recommend someone do to their rig prior to installing a turbo kit?
cough cough... Don't mind me imma just add an extra 100hp and an extra 100 lb-ft at the wheels - no Bigee, almost doubling the power.
Also curious to see reliability and extra stress on the engine, I would love to have one but I would imagine my 280,000mile motor wouldn't be to happy with me if I tried?
Any concerns with extra heat? especially down here in Dallas, negative effect on the A/C efficiency (Condenser no longer in the front) or other drawbacks from a DD position?
Obviously not even remotely close to the efficiency island of that turbo. How far you going to push it? And this will get the stroker down the road, right? I love dyno numbers!
I don't think there is a turbo that is efficient at 6-7 psi. I have looked at a lot of maps and it seems that efficiency doesn't start getting good until 20 psi. Bottom line is the significant power gain.
That is probably it for this shippable kit. It has an external wastegate, so it would not be difficult to turn up the boost. Also each kit will come with the manufacturer supplied wastegate replacement springs. The spring installed right now is a 8 psi, and we were seeing between 7-8 psi at the manifold. Realistically with proper tuning you could probably run the 10 psi spring and make closer to 275.

Your layout in the engine bay is perfect. It is very similar to what I was planning but you definitely have some better ideas than some of mine. I like your intercooler better than the ones I found for sure, the 90 degree inlet/outlet is perfect for that location.
What were people paying for the banks kit? Wasn't it something like 4K and then another 2K if you added the A2W? And the only Super Charger Kits available right now that I know of are 5-7K. I think your average person that still owns a TJ 17 years later is willing to spend the extra dough for a quality product, however your average TJ owner probably isn't looking into forced induction. There is definitely a demand with those of us who want the power but are unable or unwilling to do a V8 swap, and most of us see the shortcomings of the current available options for forced induction.
One more question. The little reservoir on the firewall just to the right of the intercooler, is that your fill point for the A2W system?
I lied when I said one more question because I almost immediately thought of another. And this is mostly my lack of knowledge with turbos. Why did you choose an external wastegate vs internal? I know external can be better in high boost applications, but I would think in the psi ranges we are looking at on our tired old 4.0s the internal would have the advantage simply due to saving a little space under the hood and a little less complexity for your average end user.
