OEM Conrods worth it?
Okay so my new build will be a bit on the cheap side. I'd LIKE to do full internals but I also know I'm really going budget where I can. I want to do the pistons to OEM spec or maybe even LAN's 11:1. IDK really, but I have low goals and this will get either rebuilt again in the future or I'll build another one to replace it. I just want to know how competent are the OEM rods? Just a PnP and a valvetrain rebuild for the most part with a light hone to the cylinder walls to make sure they aren't scored and slap it all together. I just want to know if I'm staying way below or at 300BHP will i run into issues with the OEM conrods? I'm not looking to make a monster and likely won't even see 275BHP but just in the off chance I wanted to know.

You may hear a lot of opinions of with and against right now. But I tell you this...
Never gamble with the engine's internals. What if one breaks? What would happen to your engine? It is up to you. |

stock rods with ARP fasteners will be good

Jack Laverty kicked out a stock 140,000+ mile rod only because he:
A) Was making 318 whp B) Was revving to 8200 rpms C) Lost oil pressure due to 1.5+ G's of lateral acceleration which starved the pump. A street car on street tires driving on the street will never see this kind of cornering force. For just about anything else I think you'd be fine. |

stock CR is 10:1 if I remember correctly...

Re: OEM Conrods worth it?
Are you doing anything for engine management? With the stock MAF maxing out in the 250 HP range there isn't a whole lot of room for improvement without going to a different support system. Although most of our engines are old and tired, so bringing them back to even stock power levels is an improvement.

Another alternative is going with STi rods and ARP bolts. Little more margin and you should be able to pick up some from over at NASIOC when they upgrade to aftermarket rods.

Bump for answer about the piston specs?

Re: OEM Conrods worth it?
stock pistons will be more than enough for what you are looking for.... Yes they are 10:1. I see no reason to use any other pistons with an engine you are basically keeping stock
