I was thinking of saving some money and just buying some aluminum and comparing them to some high end aftermarket ones. Then cutting some pistons out of the aluminum in a machine shop. Also connection rods could be made in a similiar fashion, although this would be time consuming and a risk, it would save some money.

Has anyone done this besides the piston manufacteres??

This is why friends should not let friends drink and post.WTF
 
This idea is ridiculous, not to mention you will hardly save any money.
 
if you think you can do it and can afford a new motor if everything gets wrecked then try it. if it works it would be cool to say you made your own rods and pistons. i personally wouldnt try it.
 
There is a ton of presion machining that would have to be done in order to make a pistion from a solid piece of aluminium, not to mention backdraft. For what new ones cost it wouldnt be worth the effort.
 
You would have to have it mapped into CAM and sent to CNC. If you were making hundreds of them, it may be worth it, cost-per-piece. Otherwise, no. And having the average machine shop do it would probably end up in engine damage.
 
yup... waste of time unless you are mass producing them.... Buy new pistons... buy new rods.... but DONT STOP thinking outside the box... thats how great discoveries are made...
 
Yeah, and yours won't be forged either. Forging is where they take the aluminum and use tons of force to push it into a die which is shaped close to the piston size, then it is precision machined. By forging the piston, it raises it's strength considerably. Yours would be much much weaker.
 
IN my opinion my time is worth more than the time it would take to make a set of pistons and rods. Just to see if it would work. Im not saying its impossable, just impractical. for exaple the ring grooves have to be perfect among other things. Stick with what works. JUst my .02
 
How would get them heat treated? Not many machine shop have ablity to do it heat treating can make or break some aluminum alloys.
 
No offense but making your own pistons is ridiculous, and IF you manage to succeed you'd most likely blow up the engine. Buy them and save your self the head ache. My $0.02. Cheers.
 
i was thinking i dont have the knowledge to do such things. I was thinking of using a block that I made out of hardened clay. ceramic coated of coarse, that should withstand the extreme punishment im going to put the block through. For example I think that This will save some money and do the damn thing, maybe not on this motor but for sure when I get a 1G.

I was thinking of covering the pistons with some kind of oil and calling it a day. That would coat them and I dont think piston rings are that important so im just not going to use them,

your advice and input is invaluable.

Piston rings are what make pistons work, thats why EVERY piston has then. DO you think they call them compression rings, oil control rings etc for nothing?WTF Rings are what make pistons work. You must be planning on using some kinda clay that I have never heard of. Do you know what pressures are inside a combustion chamber(especiallt a boosted motor)????? Im not trying to be an a$$ about it but listen to what everyone has told you. Its no practical, nor feasable. Pistons are not that expensive. I like to see people thiking outside the box but this is out side the universe.:sneaky:
 
Is this guy an idiot, a little kid, or maybe just joking around? WTF If this is a joke, why in the newbie section, place it in the hangout where we can actually have a laugh.
 
This is why I browse the forums drunk sometimes... thank you fo making my night!

Can I have whatever made you post this? my god man... there's outside the box, and then there's left field!

Edit: LOL
 
I am rofl.

Keeps me coming back to this site [that and the bastard DSM in my garage LOL].

On a slightly eschew note, I'd like to machine my own 4-rotor eccentric shaft and get another Rx7. :thumb:
 
I can't believe you guys are stupid enough to think he's being serious.
