Good Plan - Keep AC, 500hp/500tq?
Good Plan - Keep AC, 500hp/500tq? Okay, been on the forums for quite a while now, and am just getting interested in going FI. I don't have any hesitation regarding doing simple fab work, and I have been browsing way too many cast manifold turbo threads, lol.
So tell me what you think of my goals, and if they are easily doable:
1. Keep Air Conditioning -this is a must, no way around it!
2. Close to stock reliability.
3. 500hp/500tq. This will be a quick street car, it will likely never see any track time. I really am not aiming for more, although more would be gravy.
4. Use cast iron manifolds, for reliability and ease of service.
I figure I will need to switch to a BMR turbo cross-member, and do the c6 manifold setup, from all the reading I have done so far. Of course all the associated fuel and tuning upgrades.
Input or advice from anyone? Thanks in advance!

Hi, thanks for the reply. I know that you can make that power on just motor, but I would like to have tons of torque down low (below 3000 rpm). I just don't think one can get a very streetable 500/500 with a stock displacement ls1, NA.
With a stock cube LS1 to the tires? Doubtful.
I'm doing a C6/truck manifold turbo setup with a TC78. Welding up my own plumbing, stock radiator location, etc. It can be done. I'm running e85, 4L80e, stock 10 bolt rear (for now) and 500 to the tires should be completely reasonable from what I've seen.
Here's my build thread (evolved a good bit since my initial planning)

And the "Official C6 manifold turbo" thread (though a bit old)

I have the APS kit on my car. Running the stock 7psi. It first dyno'd at 508hp/513tq to the tire when I got it installed in 2007. Last year after lots of miles (I DD it & roadtrip it all the time) it dyno'd at 524hp/514tq so it stayed consistent. I did have to rebuild the turbo's (true mitsu center cartridges). I still have A/C and love it. I went to one track rental, hotlapped 8 passes and cruised home with the AC blowing cold. As of this year I have 30,000 miles on the set-up. Kit went on at 89k, rolled 120k a week or so ago. The car is a blast to drive and plenty of power for street tires. I can drive it rain or shine and it's always been reliable. So yes it is possible. Just plan our your build carefully. You can get there.

Since you only want 500rwhp /500tq, How bout a used QMP/TTi log manifold kit? You can get them dirt cheap in the for sale section and they will make the power you want and keep the AC.
My best is a 12.3@126 on street tires. Built to drive so it runs what it runs.
If you stick to street tires, the rear will be fine. Mine has survived with no issues so far.

run like stock but good power and a torque curve that cannot be beat 
I built a setup using a custom built motor mount and a pass truck and pass f body manifold. Kept ac. There is a thread with pictures. I would suggest you go this route. Stock k member too.
Oh, and hello from jersey
If I go larger than that, I would need a sleeved block, larger port heads, and also a fast intake probably.
Either NA or FI is going to cost cash. Not too concerned with the final bill, I just want to have a really fast street car with a really nice torque curve.

I'm not saying it will be the top of a table from 2000rpm up or anything...but if your goal is at or near that level i dont see the point (no offense) of going FI unless you really just want FI (or the later expandability to higher HP totals).
You'll roast tires on the highway with a big-inch motor. it'll have enough torque.
Do this. Think about what you may spend on an FI set up -- double it...cause that's the way it goes...ask around. Then take that total and figure out what NA combo you can get. I bet its reliable, drives close to stock, and puts down 500+rwhp.
