400 rwhp NA LS1 F-body...how much? How much does it need to build a 400+ rwhp NA LS1? Remember, NO FORCE INDUCTION, NO N2O, NO ALKY....ALL MOTOR. It don't matter short block or long block, as long as it's all motor.
Also, what parts will be needed?

auto or m6? its a little harder to get 400 to the rear out of an auto without heads, a nice stall converter and gears will soak up dyno numbers, but will drastically improve track times. M6s can make 400 on a dyno a lot easier cam only...i'm not saying its not possible with an auto, with the right combo, it is...i think detox is makin 420 cam only in an A4...
Yeah, it depends on your tranny. A M6 car should see 400whp with full bolt-ons and a medium sized cam. Price depends of what sorts of parts you want to put in it and where you get them. Some cams can simply be installed, while other require springs, rods, and other additions here and there. I'm sure someone who is more knowledgeable and hasn't been studying accounting for 5 hours will chime in soon.

It'll most likely M6. But I'm not sure yet. The story behind this is.....
my V6 was total loss last month b4 I start my build. I still have all the performance parts for my V6. Those parts are good for a race build V6 motor (head to buttom). I also have a V6 Performabuild 4L60E tranny and some of the turbo part. Put them all together can do a race build turbo V6 that almost guarantee 400+ rwhp.
So far I spent about $2500 in parts. And I'll need roughly another $4000 to complete the build, that's included a GT4088 turbo and all the necessary labor/part cost. So for about $6500, I'll have a newly rebuild race engine with turbo/IC and a race A4 tranny. That's my original plan.
New I've another chance to do it again, I'm thinking either do a turbo V6 as planned, or NA LS1 with 400 rwhp. That's why I wanna compare the cost to each other. What's your opinions?

ls1 now, turbo ls1 later
I dunno, the other route just isnt for me...theres a kid at work who just got a v6 camaro and keeps talking about all the stuff he wants to do to try to get it up to 300rwhp
He could have gotten a friends lt1 z28 for over a grand less than he paid for his v6, been close to his goal and have a nice exhaust note on top of it
but to each his own, variety is good but v6s aren't for me

wow, 8 posts and no one answered your question.
a stock 346 ls1 will make 400rwhp with an m6, lid, ls6 intake, longtube headers, off road y-pipe, free flowing y back exhaust, a 230/230ish cam with supporting valve springs and pushrods assuming your oil pump is in good shape (most are). all said and done you'd be looking at right around 400 rwhp for about $2000 from a bone stock m6 f-body. shopping through the classified section will cut your cost considerably.
it is late so i may have forgotten small bits, but thats about all you'll need. after you get the engine done you'll probably want to invest in a 12 bolt or 9 inch rear and upgraded suspension components with polyurethane bushings.

Just buy the parts in my sig for a bad *** street ride!! 
Here is a post of my first time at the track. I still need to pull the converter out, have it reworked and put on a set of 28" tall tires. After that I should be low 11's for sure. I do have the hook up on parts, if you need anything just pm me..

sorry, I assumed "how much" was mods not $$$
I have $4k in my motor, tranny, upgrades, and the parts to swap them into my car...I would say you should be able to get 400 rwhp for $1500 or less if you shop smart
my headers were $600 which is a lot more than you can get fbody headers for if you shop around
granted I won't likely hit 400rwhp with my cam, the a4, and 12 bolt but hopefully it won't be far off once an ls6 intake comes into play

I would sell the parts to someone that is already stuck with a V6. I could understand adding a turbo to a V6 that you already own but now that you have the option to get an LS1 I would go for it.
400rwhp is very easy to get with an LS1 and leaves room to grow

then 2 people get faster cars they can enjoy and everyone is happy lol
stall and 4.10's REALLY wake up an auto.
i would be afraid of 4.10s making first gear completely useless, I have 3.42s and its already short...3.73 might be a better compromise? (just based on speculation from my experience though haha)
with 6500 you could deff have a 400+ whp ls1 car a4 or m6 just pick your poison.
You will need basic stuff like headers,lid, maybe intake but not 100% needed, and a nice cam if you go with stock heads. Such as the ms4 or trex or in that range and you will have a nice cam only 400+hp car. which can be done for around 2k or 3k depends on how well you shop around.

There's another reason I reconsider this; with same 100k miles on clock, a V6 is about $3000 and a LS1 is at least $7000. There's at least $4000 gap here. That's why I bought my V6 for $2500 at the beginning. For the same money I'll have a full rebuild motor and tranny.
Here's another question if any of you guys know. Did the V6 rear-end same as a LS1? My V6 rear-end has a stock LSD and 3.42 gear. Should I keep it for future use? If I'll go for an A4, I'll drop a 3500 stall verter for sure.
