Z6 vs. Y7 rods! whats the difference
NEW QUESTION!!!! Ok should i use my stock rods, that have over 230,000, or buy some with less miles?
ARE z6 rods, the same as Y7????? Ok, i plan on rebuilding a y7 block that i have. Im using a y8 head on it. It has 230,000 on it?? approx? and it didnt burn oil. I have brand new pistons, and today i bought a y8 gasket, and timing belt. Im still looking for rods, and i need new rings, and bearings. My question is, will the compression ratio be to high for my future of boost???? I did the compression calculator, but im not quite sure what "piston to deck height" is? when i choose y7 the c/r is 9.9, then when i choose y8, its 9.3? help??? |
Re:Building my block (questions!)
no the comjp. is fine all you did was build a minime but with good tuning (fuel/spark) it will be find and unlike low comp turbo engines you'll have a little power in the low end

Re:Building my block (questions!)
Ok, thats cool, so is piston to deck height, from the top of the piston to the top of the cylinder??

Didnt want to start another thread so the question is at the top!
Thanks |
Re:Z6 vs. Y7 rods! whats the difference
Im thinking they are the same!??

Re:Z6 vs. Y7 rods! whats the difference
piston to deck height is how far away the piston is from the top of the cylinder wall, as you stated.
you don't want a positive number, that means it's out of the hole, and you'll be having fun with smashy smashy piston into head. |

Yea ok, thats what i thought but wasnt sure, so are z6 and y7 rods the same? or can they be used togehter?? let me know! thanks

Re:Z6 vs. Y7 rods! whats the difference
I would think that the rods are pretty much the same strength wise. I can't see a difference in 230k mile rods or new ones. IMO they are either broke, or good. ;)

Steve, its a proven fact that rods do stretch over time, not a whole lot or anything, but the stretching does weaken the rod and ---- up the CR.

get them checked for stretch. If you use different rods your bearings are going to be all different.

Re:Z6 vs. Y7 rods! whats the difference
Well im using a rod from a y7 that i have, and i looked and compared it to the z6 ones, and it has the same Underlined 6 on it? there isnt any engine codes or anything so im thinking they are the same??
Ill post pics up soon for your opinions! thanks |
Re:Z6 vs. Y7 rods! whats the difference
I thought that only aluminum rods stretched due to their low tolerence for heat???
|
Re:Z6 vs. Y7 rods! whats the difference
Im thinking that they are the same! ill have them checked out! I would think that any rod could stretch, i mena they can bend!! lol

Re:Z6 vs. Y7 rods! whats the difference
Highly doubt the rods are going to stretch, and even if they do its going to be incredibly minimal. Rod bolts are more likely to strecth than a entire rod.
I wouldnt doubt if Z6/Y8/Y7/A6 rods are all the same, I have a box full and they all look pretty much the same to me. Jeff |
