Rods/pistons recommendations
Seriousky toying with the idea of just beefing up the bottom end and freshening things up since i bought the car with almost 60k anyway and i know i will always want more power. Looking for stock compression, and bore size. As close to drop in as possible and sonething that is not prone to that "ring land failure" i read so much about.

My CP / Carrillo pkg is 10.5:1 CR, 77mm dia, and the pistons have the OEM dome configuration. Just be sure you change both rods and pistons, not pistons by themselves. Staying with OEM CR is "not advised" if you go for serious power, but I'm having great results so far.

Take a look at my build "journal" --- the last couple pages. https://www.northamericanmotoring.co...a-stuff-2.html You might have to scroll around a bit from this link to find the latest version.

I was finally able to finish what i believe is your last update. That all sounds like quite a bit of work. My hat is off to you. I think i will be happy with about 280 if i can get there. My idea behind rods/pistons is mainly peace of mind. I also just bought an air compressor and media blast gun to do my walnut blasting...i bought the vehicle with almost 60k so i figure best way to be sure what kind of state it is in is to start ripping into it.
"Ripping into it" can be a bunch of fun, also pricey with the special tools needed. Have fun ---

Interesting on your bottom end. How many miles and what kind of abuse> Its amazing how many varying testimonies one hears on these "forums" My motor with 108k was strong until turbo flange gasket blew out at track and super-heated everything incl #1 piston. I was impressed at its durability as it lasted 20k miles under 25 psi of boost driven very hard.
The only reliable source, IMO is empirical but one cannot experience everything for themselves.
I have heard from many sources the pistons cannot handle that much abuse (i.e. at the track) and OEM rods will and do fail. I remember seeing these sintered rods in the 90"s and thinking what garbage.
If going to rebuild, then do it right and costs cannot be an issue unless one is getting ripped off.
I'll find out about durability in the next 4 years and let you know. Haha.

those are supertech parts from the look of it. They write their part number right on the rods. Only down side is they only offer 10:1 and 10.5:1 pistons. We like to use 9.5:1 CP pistons for added safety with high boost cars.
Positive note Supertech sells their parts for very reasonable prices if you ask kindly for a discount.
Had a friend who acquired a full set of their pistons and rods for the price of CP rods.
