im a little worried about my stock manley rods though...

just don't wanna drop 1500 for billet i-beam rods but may just say to hell with it and do it.

your thoughts?


before I had billet rods but trying to keep it a little more budget friendly this time

 

[ugotbit03]

You should upgrade rods for the power goals you want to achieve.

yea I cant seem to get that off my mind. also the stock crank is not as good as the replacement cranks from Kellogg either....

I just don't really want have to pay for all this stuff over again

ive heard of several people running my power levels on stock stuff so I believe it will hold but its just so stressful because of all the failures I have had.

 

[brian97cobra]

anyone ever ran or seen these rods before??

k1 technology

its a billet steel H-beam rod for $665 for all 8.

Tons of guys making 1000+ on stock crank and rods. How often have we ever seen a Manley rod failure in these cars? Get your crank and rods cryo treated if you are really that concerned. I really think you are over-thinking it.

The rods you posted look nice, but I am betting they are made in China with Chinese steel and that's why they are so cheap. I would steer clear unless you can find out if they are american made.

[badcobra]

But where are they made? I would find out. Eagle is an American company that makes their shit in China.

 

[brian97cobra]

im just not sure the stock h-beams will be good enough...

I like insurance.

so maybe ill get the oliver billet I-beam rods

damn I hate they are so expensive.

 

[svtshadow]

Unless you like going through what you have been through, then you should upgrade to the appropriate parts.

If you can drum up the cash for the Oliver rods, by all means do it. All I can tell you is I have beat my stock cryo treated rods to death on an every week basis for years with the last two being just about 1000whp through an auto and I've never had an issue. If I still had a stick, I'd be at about 1050-1100HP at my boost level. My car's only job is to drive to where the fast cars and liter bikes are and deliver beatdowns. Oh, and I drove it to work today

Anyway, I understand why you are nervous. I too had a lot of issues with breakage when I first went turbo and let the car sit for several years. Last effort was to build another teksid block, reuse my stock crank and rods, JE flat top pistons, fix the fuel system and switch to e85. Been rock solid since. Good luck man.
