I'll be completely honest, I don't really know all that much about Mazda motors. But, when I was trying to find the weight of my iron 6.0 on Google and I came across an RX7 forum that said an LS1/T56 combo weighs the same as 13BT? and it respective transmission. The iron motors weigh 70-80lbs more, IIRC. 5.3s can be had all day long for $300-400 throttle body to oil pan. Where you'll be spending you money. I spent $1200 for my 6.0 LQ9. This was with 47k miles, fresh rebuild with no miles, and an LS6 cam and spring set. I even talked the guy into giving me some random front accessory pieces to turn in as cores for my f-body accessory drive (since I was planning on going EFI later with a car intake manifold). I spent $530 for my headers, $60 for my mount plates, $60 for the pilot spacer and flywheel bolts to mate it up to an automatic (TH-350). I have spent probably like $500 on the front accessory drive with new/reman parts from Autozone and brackets from Chevrolet. If you're will to run the truck intake and get the truck accessory drive with the 5.3, it makes things significantly cheaper. Then if you wanna go bigger later on, you can bolt in any LSx based engine.
