They have been machined to fit perfectly on the 5S-FE crankshaft (honed bores for proper oil clearance, lightly milled big end bore faces for better side clearance), and are compatible with 5S-FE, 3S-GTE, or 300ZX pistons. I paid $550 shipped for these new(shipping from HK to PR was pretty expensive), plus $150 worth of machining for a perfect fit. They were also balanced to within 0.4grams, which was an extra $10 per rod.
Asking price is $420+stock rods, you pay shipping my way, I pay shipping your way.
I can also include a brand new set of NPR .020" over (87.5mm) pistons and rings for $500 total shipped if desired.
Here's a pic against stockers for comparison:

Reason for selling is I was going to do a 5S-GTE but I've decided against it for $$$ reasons. They have less than a thousand miles on them.
