Default LQ4 HP Limits

I have a chance to buy an 03 LQ4 with low miles. After doing some research I am wondering if I should hold out for a later model with floating wrist pins and what I am told are better rods.

My goal is 800HP. Is there a big difference in the strength of the rods between years and what is considered the best year?

Thanks for all the help!

What adder are you going to use to get that power?

Do you plan on changing the rods/pistons or trying to use the stock stuff?

I would go for the one thats the most complete for what you need for the best deal b/c I would put rods/pistons in it for insurance sake.

I'm going with a turbo and was planning on using the stock stuff if it will work.

On my 2nd 2001 model lq4, turning 7200 on both. 1st one dies after 4 or 5 years, spun #1 rod bearing because I ran it too low on oil, not the engines fault, but several bottles through it at 150 jetting and never complained. The stock lq4 are supposedto hold 800 all day.

If the tune is on, should be able to hold 800. I would swing a 05 with the LS2 connecting rods and full floating pins.
