They have 6 different rods for the f20.

Im wondering which one or ones would be used for a built bottom end for a boosted situation?

his is a set of four matching Carrillo H-beam rods that came out of a local's F20C S2000 project. I got them in a trade, and don't need them so I'm putting them up for sale. The guy was using these rods in his F20 with K20 88mm forged pistons (30mm comp height vs. 28 of f20c), but only ran the motor aabout 40 miles before his piston skirts galded up due to him boring out the stock FRM sleeves and not re-sleeving it for forged pistons. You can definately tell that these rods only have very little run time by not only looking at the bearings, but you can still see where the builder wrote the measurements on one of the rods in sharpie (hadn't faded off yet). The rods have bearings in them, and they are for a 1.85" rod journal (which is a .030" cut on a f20c crank). They are clevite H bearings, and they are totally re-usable --- I would reuse them if I was building a motor with these, you can barely even see any wear. If these didn't have markings/numbers or bearings in them, you would think they were new out of the box! These are REAL carrillo rods, not some chinese knock offs.

These rods are 6.040" (153.4mm) in length, and use a piston with a 1.180" (30mm) compression height.


This is the ad for the guy selling them and Im wondering if I cxan used these

 

wrong tread and BTW how much are they.?
Expect the Admins to shut the tread off.

 

Peanut, please clarify. Are you considering buying them from this guy or is this an ad for a sale?

 

I am considering buying them, this is the ad of the guy selling them and I want to make sure these are for my applications.

Just like it says in my original thread

 

Used rods are not a good choice. At minimum you will need new rod bolts. Rods have to be clearanced for the crank you are using. Not a good idea to reuse bearings. Also I think you would be better off using factory bearings.

 

In general Carillo rods are good quality. If the rod bolts were not torqued properly, they may not be reusuable.

 

Sorry reading your post in bits and pieces on my phone. It is never a good idea to turn the crank or take any metal off a factory crank. the crank has a coating from the factory to harden the surface. turning the crank will lead to the crank being subject to premature wear and bearing clearances to increase. this will lead to a spun bearing and/or throwing a rod.

 

most rebuilders usually polish the crank and machine the rods to fit the bearing & crank

Carillo is one of the best rod manufacturers. They are usually very expensive too. I did not realise they make rod for the s2k though

 

I realise that, but apparently several others who sent reports didn't.

 

My crank was polished for my rebuild but came out in spec.



Polishing removes very little material. It just moves it around a bit.
