Default Cosworth rods same as Carrillo !?

Hi there, I came accross a fact where it seems that Cosworth rods would be the same as Carrillo ?

They do look quite the same... Even the laser imprint is very similar.

Cosworth Part#: 20002587 :









Carrillo Pro-H SB-2LTR>-65137S:





Anyone has info on that ?

I've seen in another post where the compare rod specs that they had the same weight ... so might there be something there ?

If they are the same. anyone advises against using a Carillo to complete a set since 1 Cosworth burned ?

I'm not going to say completely identical, but yes cosworth does outsource some of their manufacturing and it is my impression that cp/carillo makes their rods, and that arrow does the cranks.

And ACL do thier bearings.

And if you look at thier online website description for the head gaskets, it is word for word identicle to that of RCM description. But RCM gaskets look different. Perhaps both made on order by the same manufacturer.

sometimes things in this world are all manufactured to one drawing/specification.

More expensive companies tend to accept and sell things based on higher quality requirements and/or additional testing

Less expensive companies have lesser acceptance criteria.

So, you could be getting the same "thing" but more acceptable/consistent/conforming to quality standards.

I talked to the guys at cp Carrillo at sema about this and they said that they are made by them. Cosworth sets the specs and Carrillo makes them. He said the cosworth ones are better.

I’m in the same boat and need 1 cosworth rod too.

I don't know how cosworth is better than Carrillo, but I won't be using cosworth rods again, they bend too easy

if you need a single rod, call Rallispec, Dave helped me out when I bent a rod

More than likely, cosworth has an agreement that they want the conrods in a certain spec, balanced, matched, etc... Then, Carrillo can sell the "out of spec" parts (which are probably just fine, they just don't meet cosworth spec) and sell them in their name.

This is fairly common in manufacturing.

If you can get a single cosworth rod, that should be fine. Although from what i hear, its pretty hard to buy a single rod from cosworth. I know a guy thqt did it with an engine over here. Cant remember where he got the rod from in the end though.

Looking at them even from photos, they are clearly different all over.

And I'd sooner be buying Carrillo than Cosworth, no matter what claims Cosworth are making.
I'd be sceptical that those Cosworth rods are made by Carrillo.

Interestingly I see Callies are now starting to offer Subaru stuff for those who like US made parts.

Carrillo did make the Cosworth rods. I'd spoken directly with them about several years back.

As for Callies coming in, yeah, seen that too. Turn In Concepts got them to come on board and then ****...also their H-beam +2 rods crash on some forgings crown.

Just to play devil's advocate, how many more people buy Cosworth rods than Carrillo? From a percentage standpoint what's the number of failures to purchases for each company? Clearly we don't know, but also take into account Cosworth is a big-name company, so if a Cosy rod fails the buyer is more likely to complain about it than with a Carrillo rod.

That being said I went with Cosworth pistons but Manley turbo-tuff I beam rods. They might be a bit heavier but they're definitely not going to bend.

I'm more curious to what will fail first? The rods or the open desk? If closed desk what's the next failure point?

Carrillo was widely used in UK, so I am getting my data from there
Cosworth sold more stuff in the States (which is clearly a bigger market, I have to agree with you here) however I have personally bent a cosworth rod, so did my friend, I've seen other issues with them too.... their pistons are overpriced junk that take much less timing in an identical build (swapped from Diamonds to Cosworth with everything else left the same)

The only Cosworth part I owned that I love is the billet crank... but then again, its not made by them

don't get my wrong - I have much respect for cosworth engineering, they have done outstanding things, just no in the mass market field
