Scat Rods

[Alpine TSi]

I have been looking more and more into the cost of building a motor. I am pretty much set with Wiseco pistons, but am debating wether I want Eagle rods or Scat rods. I have been reading a decent amount about them and am finding that the Scats are very similar to the Eagles with an exception where the Scats add an extra oiling path, which seems better to me at least. The Scats are a little cheaper and they come with the appropriate ARP hardware, which brings down the cost more.

My question is, I have seen and heard good experiences with the Eagles, but have heard very little about the Scats in a real world application, does anyone here have any advice on the choice? I am not going to exceed 500 HP so either rod would hold up. It will be a 4G63, and probably see 30~psi with a 75 shot of nawz. If that helps.

Thanks in advance.

Eagles come with ARP hardware also.

How do you plan on not making over 500hp with 30psi and a 75 shot? If you are serious about running that much boost with that big of a shot then you might want to skip right to some Crowers. A 75 shot on top of 30psi isn't a mild setup. You might want to get the block O-ringed also to try to help keep the nitrous in the cylinders. I would feel much safer running 35psi all day vs 30psi with a 75 shot ontop of it.

I don't know much about the Scat rods besides that they are inexpensive and have a questionable name.

If you dont break 500hp on that much boost and the N20 you got some issues or a really shitty tuner...

I guess I was a little off with that. Those settings would be track/dyno only. And I am thinking that 30psi is a bit high now that I look back. The car is mainly going to be daily driven. But I suppose that the crowers might do me well as to not limit me if I decide to slap a bigger turbo on there.

Thanks for your input on the rods Shane, I too questioned the name and price. Now I just gotta find a good price on Crowers.

Scat makes decent rods for chevy small blocks but I dunno if their 4 cyl stuff is any good. I'd go with Eagle or Crower.

[slowbubblecar]

have people had problems breaking the eagle rods with over 500hp?

Eagles are fine, Crowers are excellent but spendy however if you want a solid setup with big power, I would run the crowers. I don't think I would trust the Scat stuff, I have heard a few issues with there parts with domestics, more the cranks, but quality control is a company wide issue so you have to wonder.

Someone can break 500hp with a 75 shot on a 14b.
He never specified what turbo he was going to use ;).
I've heard of the issue that mike was talking about, probably at the same time, lol.
Ghettostyle-
No-one has broken an eagle from 'power' yet as far as I know. John is using eagles (500+whp), as well as a few others.

If Eagles broke @ 500whp that'd be sad. I've been using stock rods for years making 500+ and reving to 8200.

I'd just save the $$ and get Eagles if you only plan to make 500whp. I've heard of that nation wide problem w/ the Scat products bu it hink that was awhile back now and problems have been fixed. There's also guys who race about the Scat rods as well. Either way @ 500whp i dont think you'll be breaking any rods. Seen a couple threads on some Honda boards of guys overring motors and the pistons shattering but the Eagle rods were all still straight and in spec after hitting 12k+ rpm.

The problems I have heard with Scats products were poor quality control related. The cranks were coming out all over the spectrum for tolerances and way out of balance etc. Not just one, but most of them. And this was recent (within the last year or two) That tells me the company doesn't do enough for quality control and if that is the case, I would call it a risk to use their stuff, no matter how cheap it was. Breakage isn't the only form of failure, poor performance from inconsistant parts etc is a worse failure in my book. When something breaks, you know it has failed, but if it isn't performing to design, you end up with a ghost in the machine you may never be aware of.. People should be able to identify issues like that on assembly, but there are just too many out there who don't check anything or at best just use that infernal plastigauge crap so finding those kinds of things will be unlikely. Stick with companies that use good methods across the board, they maintain good reps because of this and are worth the extra money because they take the extra time to make sure they are putting out their best.
