Took one piston and conrod out of both the RS2 and the 2.5L Tdi blocks today.
I was really curious about how conrods looked.
Unfortunatly, since I crashed my digital camera a couple of weeks ago, until I buy a new one (or somebody will present me with one
) I'm not able to post pictures.
Anyway here are some numbers and comments:
1) center to center lenght: both 144 mm
2) total weight (with bearings):
- RS2 636 gr;
- AEL 692 gr;
3) big end weight (with bearings):
- RS2 470 gr;
- AEL 495 gr;
4) small end weight (with bearing):
- RS2 166 gr;
- AEL 197 gr;
(weights might have a small percentage of error due to not "professional" scale and small amounts of oil left over them)
5) RS2 pin hole diameter (with bearing) is 20 mm; AEL is 26 mm;
6) RS2 conrod has "end to end" oil hole through it. AEL has two oil holes on top of small end, feeding pin's bearing.
7) AEL conrod has significantly bigger center longitudinal (end to end) reinforcement;
8) RS2 conrod tapers from big to small end from 25mm of width to 20 mm, while AEL is 25mm all the way.
By the way RS2 piston with rings, pin and pin clips (+ some small carbon depots and oil
) weights 496 gr.

P.S. If some of the guys running strokers use ths Tdi conrods, how do they manage the bigger pin's diameter? custom pistons?

They do look beefier dont they! Mark H ! Rods for you mate! (maybe?)
Could the TDi piston be machined down to establish a suitable compression ratio? Or is it completly differnet dimensions? i.e bore? If they worked i could see 5 plugs poping like corkes out of bottles!
