There's too many ifs and buts to give you a definitive answer. We'd have to know the intimate details of exactly what you're planning to do and ask just the right questions to be able to give you the right information. Even then there's the potential for it to be completely incorrect. The process is the same with an engineer, except he's more qualified to answer the questions and will ultimately be the person that you have to please. This will give you the basics but its not comprehensive: http://www.tmr.qld.gov.au/~/media/c792a0c9-92b1-43ee-933b-7bdd8b20842f/pdf_modification_motor_vehicles2.pdf But if you want unqualified opinion and speculation here you go: -Mod plate (insufficient information) -No mod plate but there are rules to abide by for safety. Also a surge tank for carburetors is rather unnecessary. -You really need to have a better look around here -Mod plate for the brakes -No mod plate but rules to adhere to Do all your mod plating in one hit if possible. It gets messy otherwise.

For that price you'd live with the few extra grams. I can't see the Carillos being less than $500.

Looking at this the Carillos probably wouldn't be lighter than stock: http://www.scionlife.com/forums/showpost.php?p=2237303&postcount=11 Apparently they're forged (Toyota describes them as being made from "high-strength steel for weight reduction") but I was thinking along the lines of extra RPM capability. Those rods look pretty spindly!

Ah yes, of course and any failure will probably be in tension rather than compression too. Carillo make a super light A (I) beam. 496gm vs BCs 535 H beam.

Any plan for rods or at least rod bolts? I'd be doing it as a 'might as well'. Even if they're not stronger, stuff some lighter H beams in there?

Bout the only thing photobucket are good for is deleting useful images :down:

Eh, consoles on the whole are a bit....

But you had to buy a console at the very least. Also didn't they go down for like 20+ days?

Yea but don't you like... pay them something in the first place? :P

What are you trying to prove? I feel like I'm being straw manned. Either that or we're about to head down conspiracy theory lane.

oooh baby!

Haha, I thought that was an Aston at first. Not sure why I like the Tuscan, something about it does it for me.

So a few guys we having troubles getting RC this morning and this is the story behind it (copy/paste from the placeholder page I made quickly):

I guess the one huge advantage the 2AZs design has is that if you ever wanted to make something like the F20C main cap, you could. Everything is provided on the engine block for you to achieve the same design. Just fire up the CNC and away you go. OK, maybe a little oversimplified, but it'd be a damn sight easier to achieve than on a block with a skirt ala SR20. I should add too that I don't mean to hold the SR20 up as a shining example of the greatest engineering ever, its simply the engine I have the most experience with and knowledge of.

Its a capable 1000hp engine, so how much is too much? No denying the F20C, that's an awesome design. My thought process behind the skirt on the block was along the lines of, if you have a continuous structure below the the crank center line you provide extra resistance to the bending forces in the block above the crank center line. I can see how that force would be mitigated in the F20C design but less so in the 2AZ. Am I on the right track or am I imagining a force that isn't there? The VH45 goes a step further than the SR design, the girdle contacts the skirt higher up and is cross bolted through it. Having trouble finding a good pic though: http://npora.ipbhost.com/index.php?showtopic=18663

Yea? I would have thought a nice lip like this locating the crank girdle (or an even larger contact patch) would be preferred: http://www.sillbeer.com/blog/2009/10/ Even with those the SR has issues with the girdle walking necessitating larger diameter studs. But the block skirt is below the crank centerline so its unlikely to mess up your CofG. Why not? Whats the harm if you're going to bolt on a slab of cast alumn anyway? I quite like this design: (edit: essentially the same as an F20C ignoring the whole vee thing) Irrelevant anyway, the 2AZ is what it is.

Personally I would prefer them to be filled in, not somewhere I think you should skimp on strength for weight. The crank is also sitting 'on' the block rather than 'in' the block like you see in SR, RB, 4A, 3S and probably countless others. I'm not saying that means there's be something inherently wrong with it, there's plenty of results that say otherwise already, just not convinced that performance was at all in their minds when designing it. I know there's a sump extension that bolts on the bottom but its not the same as having continuous metal. I suspect NVH and economic manufacturing was higher on their list of design parameters than saving weight, especially with what is essentially a small second flywheel inside the engine. If you make a million engines and save $1 of alloy in each engine... With the RPM, I don't envy those rod bolts job. Gonna be some serious pressures at higher RPM.

Aww yeaaa! Thats awesome haha.

http://www.briancrower.com/makes/toyota/2azfe_rods.shtml Dayum! Look at the length of those rods! Edit: Looks like its a stock photograph anyway, d'oh Sam: I think 5600rpm and 6500rpm. Edit 2: http://www.scionlife.com/forums/showthread.php?t=202535 Wow, look at that crank! :|

The growler is absolutely stunning. Was the first and only car that ever made me blurt out 'WOW' when I first saw it. Well, the rendering anyway. Hopefully Jaguar built it exactly as it is in the renderings and don't cock up their perfectly good concept like almost every other halfwitted car manufacturer does. http://www.youtube.com/watch?v=KaE3HAjuUk8

What a load of bollocks. Science by definition is forever trying to prove itself wrong, correct itself and discover new knowledge.

Buddhism does great things eh? Though in a corporate sense, Apple would rate as one of the most totalitarian corporations I can think of. They seek complete and utter control of their devices in the hands of consumers and its really only law that is preventing that. Dave: Technocracy My suspicion is though that a technocracy would probably lead to a totalitarian technocracy.

:ban:

Google makes it really easy these days. E.g. search for "define antidisestablishmentarianism" The m!nt thing was getting a bit ridiculous. It was being used rather dishonestly in many cases.

Oh you've stumbled on a REALLY old one there. Like, circa 2004/5 I think! Someone kept misspelling nearly... I think I did d.ose -> does recently too.
