Any big numbers on 5.3 turbo, with forged internals? So we keep on reading about stock or junkyard 5.3's. Has anyone built one, and what power are you making, maybe what times. Im in the process of building a 5.3 turbo, with rods and pistons, a very similar setup to my previous 406 ci, that went 8.45@ 164 mph, in my street car that weighs 3200lbs.

OP, I'm not really sure what you're trying to accomplish here. Stock 5.3 internals have been pushed to 1000 whp. Obviously forged internals are going to withstand more than that.

I'm just confused as to what the purpose is. If you want, I'll link you to a few stock bottom 5.3s making around 1000 HP and even a couple making 1300-1400. Do you not think it can be done or something? With all of the 8 second 5.3s out there, there shouldn't be any doubt that you can go faster than 8.45 with forged internals.

These ones that you are talking about, are the wheel hp or flyhp?
Im not asking for builds, or coulda woulda shoulda, but guys that have made more than a thousand.thanks

UOTE=snip;18246021]So, i know you can make 1000hp with a stock engine, although obviously it has a short life. What i want to hear about is these 1300-1500 hp 5.3 with built internals. Is it possible? Because i havnt been able to find one of these anywhere on the net. I was thinking it maybe because guys generally spend their money on bigger cubes, hence why i cant seem to find them.

What everyone's trying to tell you is yes , It can, and has been done numerous times (with the Oem parts).
All that means is with forged internals it will last a lot longer at 1000+ hp.
A stronger rotating assembly shouldn't affect the outcome with everything else being equal.
You see, Its kind of confusing when you ask can it be done?
Now it would be interesting to see if someone has pushed the limits with forged internals.

I'm really struggling here. Is it possible? Why wouldn't it be? Why wouldn't it be possible to make 200 HP more with forged internals? If you can make 1300 HP with stock internals, why exactly couldn't you make 1500 with forged internals? There are dozens (if not more) of LS motors well above 1500 HP. I guess I'm still not following the purpose of your question.
Are you thinking the block itself won't handle 1500?
Do you think that the forged internals themselves won't handle 1500?
Do you think a 5.3 is too small to make 1500 HP?
There are literally thousands of engines out there making well over 1500 HP on forged internals.
Here is the current stock bottom end record holder:
https://ls1tech.com/forums/drag-raci...3-results.html
He has ran for 2 seasons on the stock bottom end.
Plus his ET and MPH into a calculator and you come up with these power figures:
Your HP computed from your vehicle ET is 1,295.17 flywheel HP and 1,165.65 rear wheel HP.
Your HP computed from your vehicle MPH is 1,479.16 flywheel HP and 1,331.25 rear wheel HP.
http://www.wallaceracing.com/hpcalculatoreigth.php
Here is another stock bottom end 5.3. 50 dyno pulls at 1200+ HP. Turned it up at the track and made 1400hp, and raced it that way for an entire season before swapping out the rods and pistons, and pushing it repeatedly over 1400HP.

Like I said, if you don't think that forged internals will handle 1500 HP, what are the literally thousands of 2000+ HP engines out there doing for internals? I'm baffled by your logic.

Joenova, thanks for trying to help.
What im trying to find out is ,has someone with forged internals made between 1300-1500hp with a a 5.3 capacity engine. I know what stock bottom ends can do,and that forged internals will take more, thats logic, and that bigger ls's have made a milloion hp, but i havnt really found 1 built 5.3 that makes this hp.
Im building a 5.3 here in australia for something different, cos they arnt easy to come by, but id be full of hope if i knew that they can make at least 1100 rwhp.i asked if it was possible because of the small cubes.
These 2 examples you showed does answer my question.

I can name a dozen 4 cylinders and about 50 3 liter inline 6s within a couple of hundred miles of me making more than 1500 HP. When adding boost, the cubic inches becomes irrelevant. In fact, smaller engines tend to keep large turbo chargers inside of their efficiency range longer, therefore able to squeeze more power out of a given turbo than a larger engine.
Therefore, I'm still deeply confused as to why you think a 5.3 can't make 1500 HP.

Sbe 5.3 + F1x + methanol= 1259 hp.

1500 HP on 4 bolt heads without 1/2 Studs or heck even with 1/2 studs is not a smart option to chase after. 6 bolt heads and proper internals no limit on HP really as ling as the first number out of four is a 1.
4 bolt heads and small studs I would set 1100whp as max goal.

4 bolt heads will hold more than 1100 to the tire with ease.... as long as the person doing the tuning knows what they are doing.... People are giving alot more credit to those little 5/16's bolts that torque to 22 ft lbs than they really deserve.
Small block ford guys have been going fast with 4 bolt setups for years.
