I don't understand why it cost so much to build this motor and go forged??

I totally built my 351W with eagle H beam rods, new cam, springs,nitrite hardened 4340 crank,good pushrods, good forged pistons, file fit rings, studded the heads and crank , main girdle, new oil pump new sfi approved balancer , all machine work, polished out crank, good bearings, shot peened block,line bored, .030 over bore, cometic gaskets the whole 9 yards and I had $5300 invested This motor has 4 less of everything I even had to buy a used F4TE block for my rebuild on the Ford I mean what do 4 good rods cost for this motor $600??? 8 H beams cost $535.00 why so much???

Well, it is basic supply and demand. There are millions of 351Ws and less than 20k DISI turbo motors. Even less that want aftermarket forgery....

Exactly, the manufacturers are still recovering the cost of the engineering and tooling, which are probably about the same for any given con-rod of similar manufacturing. Figure many tens of thousands of dollars (maybe even 100k+) to develop the design and tooling spread over the couple thousand con-rods a company might sell, and you've got a $100 price increase per rod. If they sell twice as many it's only a $50 bump per part. Bear in mind that alloy steel is only a couple bucks per pound, so almost all of the cost is in design, tooling, and manufacturing. Even a marginal increase in volume has a very big impact on price.

Yep, @ 3,600 miles I'd only had one oil change at the dealer. Mazda NAO said the dealer screwed up and denied the warranty. That was seven months ago. I still have a car with a hole in the block sitting in the driveway.

Are they repairing your car under warranty?

UH, would not MNA be rquired to back their dealers actions??

Damn, spending that much, why not start with a cleveland??

I have spent $10K just to harden a 1500cc Suzuki motor to handle the HP mods for a 400hp DRAGBIKE motor so $4-$5K is nothing to some of us.

You would think so.

Verbally, the reps from Mazda NAO tell me that because the dealer is an independent business they don't guarantee the work performed there.

After I cited the language in the replacement parts section of the warranty booklet that includes dealer workmanship in the warranty coverage, the reps from Mazda NAO just refuse to respond.

The moral of the story is, If you think you're protecting your warranty by having a Mazda dealer service your car, think again...

We'll see who the jury decides agrees with!

Your case will probably never get to a jury; The issue is a question of law rather than fact, and I can't imagine any judge will buy Mazda's argument. If you get the right judge you may even receive punitive damages.

Heh, thanks.

I'd just like to mention that I read an article fairly recently about Road and Track's long-term MazdaSpeed3 test:

http://www.roadandtrack.com/article.asp?section_id=4&article_id=7360

Highlights are basically that there were a fair number of relatively minor repairs (at least in my eyes) but with 50,000 press-car miles on it, and probably a fair share of dyno pulls, the engine and power train were still solid. Granted the car is stock, but I cannot imagine a car seeing more abuse than a press car; just a slim ray of hope for those worried out there!
