As you asked:
Forged 4340 Steel I Beam connecting rods. Shot peened for improved fatigue life. Sizes held to +/- .0001” , finish honed in the USA. Bronze wrist pin bushings. Weight matched +/- 1 gram on each end. Exclusively using ARP fasteners.

Billet 4340 Steel H Beam connecting rods. Closely monitored material mechanical properties for optimum performance. Designed and finish honed in the USA. Sizes held to some of the tightest tolerances in the industry, +/- .0001” and +/- 1 gram per end. Shot peened for improved fatigue life. Bronze wrist pin bushings. Exclusively using ARP 2000 fasteners.

The rods are good anywhere up to the neighborhood of about 400hp. I have yet to my knowledge of any lancer reaching that high. Highest right now is Robert and he is at 339whp.

+1

K1 rods are an economic alternative in exchange for a lower HP rating. Even though they are "rated to 400hp", they may/may not fail at 350hp, 375hp, etc. If you're gonna get forged rods to build your engine, do it right the first time.

K-1 makes great quality parts. I believe the forgings are made in China. I know they are machined, shot peened and finished honed in the god ol' USA. I have yet to see a set of these rods fail. I have seen guys using these rods destroy the pistons and the rods were left intact. All these mis-informed forum guru's make me laugh.

Also, you would be surprised how many of your big name brand parts are actually made in China. Would you stop buying them? I doubt it.

I'm not disputing the fact they are made stateside or in China, I'm saying that I'll stick with my Crower 4340 rods before using a set of K1 "econo billet" rods. They are even listed as "lightweight" rods right on the parts sheet on K1's site. Crower or Pauter is the ONLY way to go if you want strength and want to do it right the first time. Both Crower and Pauter forged rods will handle numbers the 4G94 will likely never achieve.

Lancers are beginning to close in on the 400whp barrier and soon 500whp may be in sight if a big enough turbo is used. K1 rods will NOT be an option for those flirting with those numbers.

Well, I helped designed these rods with help from Tom at K-1. The whole idea behind these rods was to make buidling a block to handle decent power a reachable goal for the budget minded. They are a few grams heavier than the oem rods, we wanted to keep them as close to stock weight as possible and still be strong enough for decent power. I believe these rods could handle over 400. I agree that IF someone was to exceed well over 400hp, they will probably want a beefier rod. But I think don't think the OP is looking for that kind of power since he uses the word "budget" is in his sig. There's nothing wrong with budget rods, I don't believe anyone needs to break the bank in order to build a decent motor. So making a general statement that people shouldn't buy these rods is ignorant.

The majority of Lancer owners going turbo are going to utilize the word "budget" in their builds and these rods will be fine for them. If you say they'll hold more than 400 then so be it. I NEVER said "people shouldn't buy these rods", so calm down. I stated that people building an engine with the goal of exceeding the rating of these rods will want to go with Crower or Pauter.

You said, "If you're gonna get forged rods to build your engine, do it right the first time." So K-1's are the wrong choice? That's what I'm reading. You talk like every single Lancer owner is shooting for 400+ hp. I guess you speak for all Lancer owners.

*02Lancer* · Sep 13, 2009, 08:42 AM

I am doing a budget turbo build. But since im going to be building my spare motor i want the rods and pistons to hold up. I want to try and get to the 400 hp goal. That is with boost and NO2. So i want to make sure they are not going to break. And those using the crower rods do you have the part number of them? Thank you for all the responses and does anyone have any ideas for pistons.

lets just say.. average lancer wanting to run 12-14psi safely.. these rods r great. anyone wantin to be able to make well over 300hp is better off spending it on a little better product for longevity of the motor. but i would have to say that if i was gunna build my car to a surtain point and stop, it would be at the limits of these rods, i would rather have something i know will handle the power compared to them suppose to be able to it. i have debaited a few times on picking up a set of these rods, great price, but i didnt think it would be the smartest idea, building a motor isnt cheap, exspecially not if your have to do it twice! i want to push my motor pretty hard, might as well spend the extra money to make sure i can get home after running it all night

I couldn't agree more. If you're gonna build your Lancer for a nice 300-400whp then the K1 rods will be right up your alley. But If you're gonna try to get the most out of your engine and shoot for a constant 400whp+ and constantly push your motor to its limits with much higher boost, then you might need to look at other vendors for forged rods. Seeing as 400whp is uncharted territory right now for turbo'd Lancers, the K1 rods will be the right choice for people to go with for those that want a turbo'd Lancer with a built engine.

I got one other question. I was on wiseco site the other day and speedcorps site looking into pistons for my build. What i noticed was the k1 rods are good to 400hp but so are thee wiseco pistons. So what i would like to know is what other pistons are out there for our engine. I tried doing a search but found nothing.

cincy · Sep 14, 2009, 12:28 PM

I highly doubt a set of 4340 H beam rods will break at a mear 400hp. If they were stated as such, they were being conservative. Being forged in china and finished in the US is what most people do.

Wiseco's shouldnt have a problem either.
