My plan isn't to go above 1,000hp. I would strictly be putting this into a street car and be looking for around 600-650whp. I am finding mostly 00-02 engine in my area. anything newer people are wanting a premium on.
Sorry for getting off track, Getting 650whp is either going to take boost of some sort or your going to have to spin the crap out of it. Neither option is going to be cheap and a lot is going to depend on how much of the work you can do yourself. Paying someone will eat your budget fast.
The year of the block and crankshaft don't matter really they will all work.
So here are a couple questions for you.
What is your budget?
What do you plan on using the engine for? Street/strip/something else?
Talon, you made the statement, "They don't make 1000 HP" NO qualifiers, NO conditions.
When in fact they do. MANY do. Can't you ever admit being wrong? But above you just sidestep the whole premise, as usual.
That guy is offering $5000 to anybody who can make 1000 on his dyno for a reason. The point wasn't about the power #, which could be any number, it was about the dyno only being a tuning tool, and that the number is more or less meaningless.
Read it carefully
So this 1250 hp 5.3 is gonna run 4.80's@160 in a 3400 lbs car???
Do any SBE 5.3's go 5's @ 160 in 3400lbs or whatever?
but show up with a STOCK 5.3, and make 1001hp@ the wheel with the converter the car is gonna run with....and I will gladly give you the $5000.00 cash!!
I have nothing to side step, it wasn't me that said any of this. Acting like I care what number comes out of software on a screen? give me a break
Obviously they did and do... They made 1000hp or more and made over a 100 passes... That pretty damn repeatable in my book no matter what your eyes think end of story!
I make 127 passes, approx full wot runs per week in my vehicle. My 93 cost this week was $140 and it was a light week. If my 5.3 made 1000rwhp for 100 passes I would need to change the engine every 5 days. The way it is setup now it could last 5+ years.
I am not saying it isn't do-able. But I wouldn't call it reliable either. 240sx 5.3 engine with trans comes out in 2 hours, car is made around the idea. But it still doesn't mean I want to deal with that **** every week.
guy asking about 650:
To go 500-800 most V8 swaps include either E85 or meth/water injection along with 60-80lb injectors, and as much head/cam/intake work as you can afford on top of the turbo. Trans/Rear to handle it and thats everything

I have no issue doing the fab work myself. I don't have a budget set yet. The car is going to be a street car with the strip maybe once a year and an auto x once a year. I would like anywhere from 550-600rwhp..Do i need that much for the street no, but it feels good knowing its there

So are you planning on running turbo/supercharger or Naturally aspirated?
So are you planning on running turbo/supercharger or Naturally aspirated?
Either going to go LSA supercharger or a on3 7876 turbo. Those have been the two routes I have been looking at. I keep changing my mind on a daily basis with those two.
I'm running an LSA supercharged 6.0 with LS9 cam and TR6060 6spd, I haven't had it on the dyno but similar builds are around 500-550 to the wheels. Better cam and Ported heads plus pulley the supercharger would put it in the 600-650 range, Throw in a ported blower with the other mods and you could be at the 700+ rwhp range.
I'm happy with what I have, I have tons of low end torque and it pulls pretty hard until my self imposed 6,000rpm redline. I have to ease into in 1st and 2nd or it will break the tires loose and can't even think about using 100% throttle until I'm in 3rd gear and I'm running Nitto 325/30/19 tires. A turbo will get you more peak power and probably get you there cheaper. I have around $2600 in my brand new complete supercharger and factory accessory drive. I looked a couple days ago and prices have gone up considerably. Now to build the same thing would be closer to $3200 and that's with a used supercharger then add in the cost of injectors ( I bought ID850's $700) and a decent fuel system and you realize it takes a decent budget to get it done.

This is the route I keep coming to the most versus the turbo. I have not figured out a budget yet, but the engine wouldn't have to be built quickly as the car its going in won't be ready for a good amount of time. Frame on one side of the garage and body on the rotisserie on the other side.
With your 6.0, did you use ls6 heads to match the LSA or did you use adapters? Also, what year 6.0 are you using? I was looking at running the stock cts-v crank pulley and running a 2.40 blower pulley to give me 15lbs of boost.

Two more questions, did you use the stock 6.0 computer and harness and just have it reprogrammed? Your front accessory drive, did you piece it together or by a kit for it? Sorry for all the questions.
That looks nice. Unfortunately I will have to mount my A/C up high on the passenger side. If I try to keep my A/c down low I have to notch the front crossmember and I really don't want to do it.
Was there any specific reason for going with the Holley EFI versus stock?
At the time the Holley system was a little cheaper than it is now. I added the cost of a Harness/Computer/Wideband/added gauges and HPtuners software and I was within a few hundred dollars of the Holley system. The Holley system does so much more than the factory stuff can do but it's not really necessary, I like new toys so I bought it.
but it costs 100~ horsepower compared to turbo around 500-600rwhp
Show me 500rwhp supercharger car, that is a 600rwhp turbo car. the belt style rotating force absorbs what would have been rotational torque for the tires, that the engine had endure extra stress from axially applied pressure to the piston to produce. Important info if the bottom end has a limit related to piston stress.
Here is a comparison of roots and twin screw. Roots Red/ Twin Blue
There is actually a transducer used to measure the torque required to spin a supercharger or anything else that requires rotational force to function and twin screws are a lot more efficient than people realize.
No doubt a turbo will make more peak power if everything else is identical but we all know that never happens when you line up against someone elses car.
There are turbo cars making big power and also nitrous and cars with centrifugal/roots/twin screws. It all depends on what your personally preference is. For me a street vehicle with a manual trans and twin screw is my choice, My other build has a 6-71 roots on it and it will makes some decent power but also looks badass (to me anyway) I know I can make over a 1,000hp if I put a turbo on it but I'll settle for a big ole polished heat pump that I can barely see around that only makes 900hp because I think it's cool.
what do I look like, google? I have the same internet you do

The hp consumption is the product of a number of things, the blower will consume less power at a given speed if it is operating at a lower boost level (pressure ratio), provided it isn't way off to the right of the compressor map (blower too small for the engine).
That said, a centrifugal blower blower typically consumes the equivalent of 15-20% of your flywheel hp at elevated boost levels. That is to say if you're making 1000hp at the flywheel, the blower input power approximately 150-200hp.
