No matter what you decide to do, you either need somebody really good who can help you or you need to be really good at reading plugs. They are the only thing that tells you whats going on inside the engine.

Just slap at 80mm+ t6 based turbo on there with a big hot-side housing and all the supporting hardware (BOV/WG/Carb/Pump), let it eat and report back on how the nascar engine holds up. dumber stuff has been done and held together. you probably wont make 1000+ but you'll get your feet wet, see what flys apart and go from there. These are uncharted waters in mopar-land, even more so with ex-cup parts.
I'm going to throw a BW 75mm($400 @ ebay) on a small block MP 3.454in crank($50 @ Carlisle), Lentz 6.2in. roundy-round takeout rods ($150 @ ebay) and custom pistons in a free 318 block. Shooting for 10's for $5k including whatever kind of disposable a-body/f-body/dakota I find on craigslist for cheap.
Why would I do that? I bought my stuff before it was cheap. I've got a lot in it. I'm not gonna grenade it just because I want to see what will fail first. My block has bushed keyway lifters, no way am I spending money to do that again on a count of stupidity.
You have fun blowing up your 318 diplomat...

You need to get on a turbo specific site since you are brand new to this to answer a lot of questions and look at other peoples builds reguardles of brand..a engine is a engine reguardless of brand. Turbomustangs.com is full of info and will answer all your question all you need to do is read alot

As bigtime pointed out, the EFI doesn't (ok... can but shouldn't) control the fuel based on live O2 information. If the car goes lean, the EFI is usually in "open loop" under full throttle. This means any lean/rich spikes WON'T be compensated for. Works just like a carb.
Also, anyone who thinks setting up EFI to work is easier then a carb is fooling themselves. Yes once you get it dialed in, changing A/F ratio is as simple as a few key strokes, but I can tell you that I've made 2 jet changes on my blow through carb, and it idles and drives perfect with that little effort.
As for the turbo, yes you have a ton of room for a T6. However, if you're going to use that motor, a T4 would probably work (just because it's only 358"). As others have suggested, get on some turbo forums.
The turbo information on here is sparse and you've got a LONG way to go before you start buying parts. No offense, but if you don't know the difference between a BOV and a WG, you're not ready to buy any parts. Don't take that the wrong way, it's just there is a lot to learn about turbo's that is a lot different from NA stuff.
Seriously though, you need to pick a real HP goal. That is the biggest problem that gets people into trouble. Saying I want to make 1200 or more doesn't help anyone point you in the right direction. Remember that you need a chassis, rear axle, fuel system, etc to support the power. Set a plan and stick with it. 1200hp is A LOT more then what you have now, and you certainly don't need a R5/P7 motor to make that happen. You could sell it off and be miles ahead with the project if you did something more conventional.
BTW... one word of advice, E85 is probably not going to work at the ice drags. It doesn't start very good at E85, and in the cold states it gets watered down to E70 just to get cars to start/run/idle right in the cold. I think you'd be better off sticking with pump gas and an intercooler. The cold air will work great, and you can make all the power in the world on 93 and a good intercooler.

There are things that I agree and disagree with on diz's post. First, the wg/ bov question. Yes- you need to spend some time learning the whys and hows of boosting an engine. Again, no disrespect but anything you aren't sure about should be discussed(like we are doing now) before you make your plan and start collecting parts. I also agree with the e85 advice. I don't think it's for you. I don't agree with getting rid of that engine. It's a sweet piece, and with a bit of changes, will work great. No way will a t4 based single turbo work for this application. This engine will need the highest exhaust flow available. I would keep the cam thats in it, and select turbos that will keep the pressure ratios as close to 1:1 as you can get. Efi will give you absolute fuel control over a much wider dynamic range than a carb will be able to control. A blowthru carb on a 700 hp engine will be able to be tuned acceptably, but when you are trying to strech the curve out over almost double the fuel demand, and still maintain nice driveability, I feel the work to get a carb to work anywhere close to efi would be like chasing a rainbow. I will suggest picking an efi system capable of dis ignition. If driveability AND power are important to you, take into consideration the fact that there are ignition events that are needed to happen from 0 degrees to 50. Try to control and phase a distributor between those ranges. Good luck, that will be one bad mambo-jahambo with a set of hair driers on it. My suggestion about turbos down by the starter was more of an example of what you can get away with with a dry sump. Normally turbos need a gravity feed to a level much above the pan level. You are free to do as you wish with placement.

are you building for a class?
No, the car is really not built for any class. I built it and use it at the ice drags, which have few to no rules for modified or time classes. But since going to the strip last fall I'd like to start racing asphalt. Not really sure on what classes I'd even fit into.
