MAPerformance FA20 Short Block

What would be the reason for one to choose the Carrillo rods over the Manley rods?

Among other reasons, I believe the H-beam should be stronger than the I-beam which is lighter. Not to say the Manley is weak at all. Carrillo has been producing quality race stuff for a long time and they tend to have immaculate attention to detail.

Interested in this and the TB!

I believe it is actually the other way around. H beams are lighter, but an inherently weaker design. I beams tend to be heavier, albeit naturally stronger. That said, Carillo's are still very strong H beams, and I don't think anyone currently makes enough power on an FA20 to really even realize the strength limitations on those rods, much less a high quality I beam.

A long while back, Ferrea stated that they would be making a valve set and maybe a cam set for the FA20. Do you plan to consider these as choices for a build?

I think you might have it backwards. I beams are lighter, H beams are heavier.

That would be true if both rods had the same thickness, material etc. However, the H beams I've seen have had much thinner walls, and were a lot lighter. If manufacturers of H beams made them to the same thickness as the standard I beam offerings then yes, they'd be both heavier and stiffer, but they generally do not. I have yet to see an H beam offering for a Subaru that is heavier than a comparable I beam offering :P


In any case I don't go to Summit for engineering enlightenment

A little bit more data as well: http://forums.nasioc.com/forums/show....php?t=1902135

I apologize, I simply did a quick query and found that video that stated the opposite of what you had said.

The Summit video did speak generally and seemed informative though.

MAPerformance could maybe give the weight of both rods in their short block offering versus the stock rods?

[DeliciousTuning]

What is going to be a big improvement in general over stock is the fact that just about any aftermarket rod you get is going to be either forged or billet machined from a forged blank. Not only should this be lighter than stock regardless or H or I beam, it will be much stronger and fatigue resistant.

On a side note, I am noticing a interesting trend among failed motors. Seen 2 at Infamous now that came in blown with really terrible bearing wear. Common link was both a lightweight flywheel and lightweight crank pulley. I was skeptical until I read of yet another one on Facebook today, car was relatively stock except for a lightweight flywheel and crank pulley; motor just gave out. It is a bit interesting.

But hey, that's getting off topic.

The engines most likely to give out are the ones owned by enthusiests.

I think as time goes on we'll find the common links to motor failures. It would be a bit odd because the EJ doesn't really have any issues with lightened flywheels and pulleys. It is a different engine though so you never know, if something throws things out of balance a little bit. Could even be flywheels not being completely balanced correctly.

Anyways, always good to see more component options for the engines. I would also agree any aftermarket rod is going to be way better than stock and likely beefy enough people would never break them on this engine.

Then I beam it is!!!
