piston help

[talon55]

does the 1 g 6 bolt pistons and rods are the same as 7 bolt

 

[luvmygst]

no. The 1g has better rods, the 2g's have the better pistons(higher compression). rods and pistons are diff from a 1g to a 2g.

No does 6 bolt not = same 7 bolt.

Translation- No the 6 bolt pistons and rods are NOT the same at 7 bolt.

6 bolt rods are bigger then the 7 bolt therefore they hold more. While the 6 bolt pistons are not worse but not recomended. There compression is lower its 7:8.
7 bolt rods are thinner. While the pistons can hold more punishement usually. With a high compression as well.... weighing in at a whole 8:5.

can i put the 7 bolt pistons in the 6 bolt block?

Yea its quite common now. You have to have the 1g rods modified to fit the 2g pistons. The pin end has to be narrowed .100" and the pin hole opened up by 1mm. I am having a set done now at a machine shop for $75. Its a good cheap combo for the power it will hold

I just cant put the 7 bolt piston and rods in the 6 bolt block

I guess you could if you wanted the weaker rods. The crank end of the rods are the same dimensions. You would gain some compression and give up some strength.

k thank you.... NO this is for someone elses car....
MY car has
Eagle Rods w/ ARP rod bolts
Wiseco 7-Bolt Stroker Pistons w/ Rings
Clevite main bearings
Clevite rod bearings
4G64 Crank

Wiseco 7 Bolt Stroker Piston Compression Ratio - 8.8:1

Eagle 7 Bolt Rod Length - 5.900"
2.3 stoke


did anyone use this kind and how much can you boost the most but safe
