One of the fastest cars at the local events is a C5 with a Roots. You want the boost to come on fairly soon.
The LS block is pretty stout
The weight advantage with an LS isn't as much as you think.
I know someone that weighed them, forget the #'s

When Directv used to be able to run Youtube I had a buddy over and ended up watching tire smoking NRE videos all afternoon.Its like **** for gearheads.If he did all that work in some kind of cad-cam I am sure he could send you all the engine and parts to do your own-If you have the bucks.Probably $100k+.

There is no doubt NRE has a solid settup.
I have personal experience with similar power numbers in my C4, that when sitting in 90F weather in Atlanta on 93 octane, wants to melt to the ground. After 2 years of thermoscans, shrowding, and $$ in parts, I have finally managed to reliably reject the kind of BTU's these motors make, while maintaining the stock hood, and stock appearance.
A true anything beater on the highway
Next, this owner has the Dana 44 still in. It is really unsafe trying to run 1500 ftlbs into that rear settup, I hope some attention is given.
His journey is out of the gate and just beginning.
Nice Job NRE World Class work you guys do. I really respect the time and effort to build reliable turbo platforms!

I am certainly no guru but I agree here. My 90' has a semi serious motor in it and it is not taking a tune. One of the seriously respected tuners on here is tuning it and it won't work. Stock won't do it.
I ended up with a Gen7 now just to run N/A sbc.
OTOH if I could get a reasonably priced bolt on turbo / blower kit I would have to buy one.
We have a handful of ECS kits in C4's, they are just bolted to an LS swap. 
Guys the biggest problem here in my humble opinion is not the car or making a kit, it's the engine management. The computer in the car is relative to it's time frame. Think of what a cell phone was in that time frame, now compare it to today.
I know it can be done, I just do not feel it can be done consistently, nor would I want to be the one tuning it. How can I sell a product and offer no support for the tuning of it? So a C4 kit will never be made here, again terribly sorry, but there is a good reason why the big name tuning software companies do not support these PCM's.
