yea I was planning 91 and water/meth. no 93 here that ive seen!
here is what ive found. everything else is 91.

found 2 e85 stations. about 20 mi away from me(not proven that they still sell it). the others are 50-100+ away

I agree. I may reconsider CR, but we'll see as it gets closer. Reason I went with 11:1 is if I really wanted to I could stay NA and push nitrous instead. not the best for max power on boost, but it should handle decently if built properly. I may try and get tuned on 100+ octane since its more available than e85 here..

What pistons did you actually buy?
Because 11:1 is typically designed for NA... Meaning the piston strength won't be up to boost requirements. From what I understand, most NA pistons get material removed from them vs their boost counter parts, to save as much weight as possible. I'm not sure if the material changes too, because I know they put a priority on making the piston lighter. VS for boost you have to deal with a much greater thermal load, and pressure load.
If it's a NA piston not designed for boost, you might flat out break it.
If it's one of the custom high comp boost pistons then you'd be ok. But even then I don't like the idea of above 10:1 on boost. It works, but the extra power... I don't think is really worth it. There are other ways to get better response, and more power/spool that don't put your engine on the knife edge.

thanks for the input resmarted. They are wiseco 11:1 and actually heavier than the 8.8:1 pistons. so extra material and nothing removed and same material as the low comp version. With the tomei 280/11mm cams, that should help out on the compression a bit i'm guessing.
Here is the current parts list of what I Actually have now:
Wiseco 11:1 96mm pistons
HKS headgasket
ARP main studs
ARP l19 head studs
Tomei 280/11mm intake and exhaust cams
I also plan to call up wiseco to see if I can buy upgraded wrist pins if they make a heavy duty version.

Definitely should call wiseco and ask them what to do for clearances and to order those wrist pins. They know what they're talking about.

havent called wiseco yet, but they have the pin upgrade listed in their catalog. It is the same material, just 1mm thicker walls. still worth it for the $80 that it costs though for a little more safety. will definitely pick them up.
I need to call them about bore sizing and wristpin/piston power handling at the same time.

Wiseco's off the shelf wrist pin upgrade is the same material as their standard wrist pin, just 1mm thicker, I think they're $20 a pin.

Bumping this up again as i am back in the market for rods. Its been a while but still working on the build
Car has just been on the back burner sitting on a lift in my garage collecting dust. Also added a few more parts to the inventory though.
between pauter and carillo not sure which rods are the strongest.
