2G Are these pistons ok?

[Nick456]

So im looking at a 2g to purchase. Everything looks great but this is the info on the engine build/rebuild. Does the piston choice seem ok?
"Stock rods wesico 10:5:1 stock bore pistons cal race bearings all arp hardware except flywheel bolts. Rebuild t28 turbo"

The 10.5:1 ratio is what concerns me personally. Would this setup be good to start a 16g pump gas daily driver build on? Looks like way too high of compression to me but im asking the more educated fellas on this one. Thanks everyone.

That C/R is high IMO . Up to you tho in most cases just limits you on boost, Higher C/R lower boost What are your plans just a DD??

Should be a good off boost car and good for low boost on 93 octane.

If you buy it you should looking at going E-85 if its available to you. And with high compression you'll want to stay with lower boost. But you will make more power on lower boost with the high compression compared to the same boost level on a lower compression piston.

Not a fan of high compression builds with these cars. Most of them end up so boost limited that they make a good deal less power than a low compression build.

9:1 seems to be the point of diminishing returns for a pump gas car.

im with wiseman donniekak but not everyone is limited by pump gas. in my area 91 oct is the best i can do.

I agree, 10.5:1 is for race cars chasing ever last hp. Not for street pump gas cars. I have a 9.5:1 setup in my beater gallant and it sucks.
