I am building a VQ35DE motor for a project and was looking at rods and pistons. I would like a VERY light rotating assembly. So, I thought I would start a thread, hopefully we can get all rods and pistons weights availible for the VQ35DE. Please chime in if you have info on aftermarket or stock.

Carrillo 'I' Beam ======= 493g
Manley 'H' Beam ====== 510g
Carrillo Pro-Sa 'I' Beam = 517g
Carrillo 'H' Beam ====== 544g
Eagle 'H' Beam ======= 555g
Manley 'I' Beam ====== 605g
Pauter 'X' Beam ====== 645g
----------------------------------------
JE 10.5cr 95.5mm ==== 363g

Thank you.
I never looked in the forced induction.

 

Don't drive yourself crazy gram counting. Its important to choose good strong products when dealing with the bottom end. Failures are costly to repair. Also note the crank and flywheel can negate any gram counting you've done.

 

I am 'gram' counting due to the fact that my motor will be N/A. Also, I dont see the point in cutting my crank and getting light weight pullies and flywheel/clutch if I am going to just heavy rods and pistons. My thinking and practice with all the motors I have built is, If I have to get rods and pistons then why not have all information vs just picking whatever. also the heviest combo is 13.9lb+/- vs the lightest 11.23lb+/-. Thats almost 3lb the motor doesnt have to throw around. This is alot of savings by doing alittle research.

 

That's true, but if you knock out the Pauter and Manely I rods and compare the others the difference is closer to 1 and 1/2 Lbs, which is still a sizable amount to consider but not so crucial. As long as your counting for the right reasons I see no problems, but I've seen people obsessed with gram counting the oddest items and only get into trouble later because of the weight conscience choices they made. Just my 2 cents.
