Whats up I have a 2003 k20a3 base RSX. I have already put a turbonetics turbo kit in it with Kpro, a 3inch kteller exhaust, bigger injectors, short ram intake dual disc clutch ECT. you get the point I have a good amount of money in the car. I'm running currently 10psi and have been for a little over a year which is the max amount of boost those shitty k20a3 connecting rods can handle. I have been looking all over and cant seem to find forged connecting rods that has a center to center distance of 5.4720 IN. with a big end housing bore clearance of 2.0079-2.0087 IN. or in other words forged connecting rod that fits on a stock piston and a stock A3 crank. please don't tell me I should just go buy an A2/Z1 crank because I already know this I'm just short on cash and I'm pulling the motor to do some other work on it and wanted to through the rods in while I have it apart. thanks for the input

Just so you know, K20A3 rods have the same center to center distance (and diameters) as the K20A2, K20A, K20Z1 and K20Z3...

Right now I have a Manley spec sheet with exactly the dimensions you mentioned (Manley part #14404-4). I also had the Eagle info in front of me a few days ago and I'm quite certain it was the same. Can't recall if the wrist pin sizes were bigger or smaller than stock though.
