hey guys im just not quite sure if this would be the correct section but i was wondering when running a FI setup ive seen a lot of people recently getting 5.3 vortecs. unless im missing something wouldnt you rather have the extra displacement from the lq4-9? someone please fill me in!

 

Because they are cheaper.

 

What he said^^^ and they are tough as nails!

 

Dirt cheap to replace and about as boost friendly as they come.

 

The last stress test I seen was 1200hp stock block. If it blows depending where you live 500-1000 bucks for another junk yard motor and drop it in and the way you goooooooo.

 

Agreed! Search here on the FI setups. You will see some crazy power made with these 5.3L Ive decided to switch my build from a turbo 6.0 to a 5.3L turbo because it's cheaper and it handles boost very well.

 

Which is weird because you can find 6.0's for not much more. I got one complete for 650 with 105k on it and the other for 700 bucks

 

i paid $660 for my low mileage 4.8.... 5.3's were about the same but they didnt have any in stock....6.0's were $1200 at a minimum......IMO not really worth the price since you could put that money into a 4.8 or a 5.3 and mop the floor with the 6.0

 

As everyone said there cheaper, some have gotten block for as lil as 300, but its not uncommon to pay alot more, if your not going boost and staying na go for the 6.0,

 

Supply/demand. That's where the price difference comes from.
My local supplier has 15 4.8/5.3's on the shelf. He has 3 6.0's. This reflected in the price:
4.8/5.3's All you want, dressed, for $600.
6.0 $850, dressed.
None are what one would call "low miles". Most well over 100K.

 

I dont see the point in going small because once you get the feel of a turbo on a v8 you will ALWAYS want more so might as well spend 200 bucks more to get the 6L

 

You want more just turn the boost up

 

Exactly.
Read my Sig.

 

well by me it was either $350 for the 5.3 or $1200 for the 6.0..... guess which one I went with.

 

The $1200? haha obv choice is 350 since you can get 3 for the price of 1 lol

 

both 6.0 and 5.3 in the stock form can handle the same hp..obviously the 6.0 will make more power with less boost.
but why not go for the cheaper one if your on a budget.

 

In stock form they will both hold the same power and the 5.3 is half the price and more plentiful. LKQ on ebay has had them for $299. with a warranty...lol.

 

I agree with that. Problem is maybe i'm wrong but if your on a budged Don't do a Turbo motor haha This **** adds up so fast!

 

Truer words have never been typed

 

Wait the 6.0 will hold same power as 5.3? Id rather use bigger motor if thats the case. Can get both real cheap in junkyards with 60k miles range.

I was going 5.3 cause though pistons rod combo was unique for boost. Is there any disadvantage other than the few hundred dollars?
