perhaps you guys need to take economics 101.

people left and right build ls1 thus companies that pay tons of money for the machines that build them are compensated faster.

whos going to buy these rods? only a hand full a year. so they need to charge more to pay for the cost of building them

 

please, like they have to buy a whole new cnc or lathe or whatever mold..... NOT! its all computerized. and they own all their equipment, its just good old fashion gouging. how much are SRT4 rods?

 

Wrong, They have to design the rods (CAD/CAE), that costs money. They need to build fixtures for machining and inspection (minimum). They need to pay someone (CAM) to write the program for the CNC machines. There is more than you think that goes into the CNC mfg of a part like this, and all of these things cost money. Unless you have worked somewhere that produces high quality, tight tolerance components such as these you don't know what you are talking about.

They don't just slap a slab of steel on a machining table and press the easy button

 

true, and if they see a high demand for the parts, prices will go down. other companies will see the demand, and start offering parts as well. that will mean competition, and good 'ol capitalism will take over from there.

 

Forged parts require parts specific dies. They have to be designed / manufactured / tested / adjusted etc... Then you must figure the cost to design the rods themselves, the setup cost for each process they go trough, the cost for the burnishing or honing tools used for both the big and small end. You also need to train your employees for these new parts, make more quality controls at each production stages when making a new part...

Honestly, people always underestimate how hard it is to release a new product. I am a mechanical engineer who works in design and manufacturing and I know that every time we setup a new type of part I have to work 2x as much as usual...

 

This made me lawlz

 

In Carrillo's product lineup they actually have 3 part numbers for the LNF rods. 2 appear to be H beam and one is an A beam.......what are the differences and why did TTR chose to stock only 1 style?(or are they all the same $ for each style?)

 

IIRC, the only major differences between the ecotec rods are the lengths and wrist pin hole diameters. Thus, the LNF and LSJ rods should be pretty much compatable, but switching lengths will change your compressioni ratio and your piston to valve clearance. Seems to me that using LSJ rods in a built LNF would be a decent way to pick up a little more compression...

Edit: Wow, the length isn't really much different either. I wonder why GM bothered to make four different lengths instead of sticking with just two...

 

Yes but for how long?

 

Same price for both H's, just a different 1/2" cap bolt... Only Difference...

The A beam is a bit cheaper (~$50 for the complete set)

Most want "H"

So yes, there are 3 different rods available for each engine (LSJ and LNF) 6 total rods.

H style and A style

 

We now added an option for the tool steel (H-11) and multi phase bolts for the H beam here. In addition we added the SA (Super A) style rods.

 

i think he means pistons. even though there are aftermarket pistons already.

 

I dont see why you guys are complaining over these, if the GA would have had a aftermarket support like the CSS id still be in my GA

 

theres aftermarket pistons....yes but they are for the stock bore size.

 

If my GA, you mean Grand Am, then, there is a lot of aftermarket support, it just depends very specifically on what year and engine you wanted. Their are a lot of components for the 2.5L Iron Duke motors, the 2.3L & 2.4L quad four motors, and the 2.2L ecotec, in the last few years of the Grand Am. Not to mention, there are a lot of Funny-Car based Grand Am Rwd kits, designed for your choice of v8. Suspension wise, a lot of the "upgrade" parts for the cobalt started as OEM Grand Am parts, such as the knuckles and hub/bearing assemblies. Personally, I think a '04 Grand Am with the 2.2L ecotec could be a lot of fun, but, I don't really need another project car right now.

Edit: I should mention that there is no point in messing with a GM 60 degree pushrod V6, thus, the lack of any mention of the 2.8L, 3.1L, or 3.4L engines...

 

hmmm I wonder how many people will be getting these anytime soon.

 

already sold 1 set of the H style LNF with the CARR bolts...

 

oooo ooooo oooo I know who bought it! They'll be installed soon after he gets them. I'm sure he'll post up how he likes them.

 

If he wishes to post, he may, but we do not share customer information of any kind public.

 

Oh I know. I wasn't going to post who bought them. Depending on how he likes them you might see me ordering a set soon as well.

Do these need to be tuned for on a stock turbo car?

 

Tuned? Meaning computer ECU tuned? No.... Not for replacing the stock rods.

 

If ZZP doesn't release their stroker kit next winter, I will be going this route. With Clevite Bearings, ARP studs, Bates sleeves... yeah, should be an ok setup.

 

LOL that would be a sweet setup.

 

What are the differences (besides price, of course) between the H and A?

After trying to do some research, it seems that H is seen as a superior rod to most, but I can't find any mention of an A type for any vender besides Carrillo.

 

I believe H is stronger and lighter. I have only used H in aftermarket builds myself.
