Sorry for the lack of updates. Been very busy with my new build and other stuff. Regardless, none of the other manufacturer's got back to me with any info :sleep:. I updated the K1 rods and Mahle pistons with the actual data from weighing mine. Pistons came in 21g heavier since they were quoting me for their 4032 version and not the 2618 version that I bought. But they are still lighter than others in the list when assuming the same pin thickness and everything else for total weight. I really wish someone with a new CP setup would weigh theirs since they are the most popular. Also, my K1 Rods came in 3g lighter than they were supposed to. Lastly, I added the Tomei H Beams that someone posted above. Thanks for the Tomei info!

Posting my findings
weisco pistons and k1 rods
Thanks for the adding to the thread. Those Wisecos sure do look really nice! I added the Wiseco info above, and adjusted the K1 weight down 1g to split the difference between yours and mine. Glad to see someone else trying out the K1's. Good luck with your build and take care sir!

just a qiick thought. Ive read that the vvti rods are smaller than the non vvti rods. Is there any weight difference?? If so what is it??



further research indicates they are the same
As someone mentioned, the non-turbo GE VVT-i rods are much lighter, but it's definitely not a good thing. Those things are twigs and will snap as early as 400whp!

I am not sure I understand all these numbers or where they fit in above? Please explain. Thanks!

a) is radial wall thicknes
b) is axial width

example Mahle 1ND ring a=1,2mm b=3,0mm this fitting to the piston ring groove

Mahle
1ND - 720 gram force
2ND - 740 gram force
--------------
1460 gram force X 6= 8760 gram force

OEM
1ND - 1460 gram force
2ND - 1120 gram force
---------------
2580 gram force X 6= 15480 gram force

this is a friction reduction of 43% on the rings in all 6 cylinders

Oh I see, and thanks for explaining, but I think thats a little more detail than I want to put into the charts above. My charts are really just for all the physical weights of all the rods and pistons. Thanks for adding the info though and take care!

Have you personally hand weighed these items, or did you just get the info from a website somewhere? Some of those numbers contradict what I have seen elsewhere is the only reason I am asking. I just bought Mahle and weighed them myself, and they are no where near 313g. Thanks!

yes i have personally weighed the parts, i have two sets of Mahle
with the JE Piston 86,50mm i mesure 330 gram what you mesuret to.

OK, your JE numbers match up on the piston. Did you happen to measure the rings, pin, clips weight?

On the Mahle, they make two different versions for the 2JZ. Do you know which model number you bought. They make a 4032 and a 2618. I bought the 2618 ones and they weigh 340g, so maybe you have the 4032 ones which should be lighter. Please check on that if you wouldnt mind. Thanks!
