Im done wasting my time..We could sit here and go back n forth all night with you taking me out of context to make your point and get nowhere. If someone is lazy enough to half *** something so serious as the internals in there engine then do it up there playboy.

I guess I just believe the motto do it right the FIRST time a lil to strongly.

Just because a piston is used does not mean it is bad.
Too many people don't know jack about anything anymore and think you have to put new stuff in any time you change anything.
There is nothing lazy or half assed about it. If you don't need the powergoals justified by forged pistons/rods, why spend the money just so you can be a poser and run around with your forged engine only producing 200hp.
If you have a properly tuned engine with knock sensor you will be way better off than trying to over engineer an engine for potential shitty tuning that will kill it. 95% of engines that granade are not granading when running as intended, power loading very rarely destroys the engine, its detonation that can kill even the best damn engine you can throw money at.

I am a nuclear engineer by profession and have worked on helicopters for many years before that. I have access to all the equipment needed to measure and check pistons or any engine parts for that matter, including access to equipment to check for microcracking and other material damage.

I have done my homework and made an educated decision. So, dont tell me I am halfassing any thing or am lazy.

Oh by the way, I would love to know what your mechanical experience is. Not that it really matters because you will probably come back and tell me that your grand daddy was Henry Ford and you rebuil your first engine when you were five and you recieved the Nobel Prize for engine design. Seriously, think about what you say in the future. How old are you by the way? I think this should be shown with everyone's ID!

This is the kind of thing that is killing our country! Just because you have a damn opinion, doesn't mean we all have to hear about it, especially when it's none of your business.

Sounds like you know what you're doing; you've done it before; and have the tools/micrometers/etc to do it. So go for it. As you said, most people don't know what they're doing, which is why I would discourage them them from doing what you're doing.
I'm an engineering student, Ive built a few engines, and I know my way around a machine shop; but I don't have the experience you do, and because of this I personally would be uncomfortable doing what you're doing.
Tw34k is a good friend of mine, and I know he wasn't trying to be an ******* or anything. He's no idiot though, hes done some engine building himself, and does some work tuning. I learned a lot of what I know about tuning from him, and the whole reason he joined this forum is because I told him about all the great tech talk on here, which he wants to learn from and contribute to.

This whole things is just a bit of a misunderstanding, so lets just let it is slide on. No hard feelings.

Thats fine. Im sorry for getting IRATE!

My biggest point is simply that this is a WANT TO BUY section and all I wanted is to get some usable pistons. 23 posts later, I still want my pistons and have not goten any relavant posts or messages. Instead I have to deal with unneeded comments. And on top of that to be called lazy and accused of doing something half assed, those terms make it personal.

As you can tell by my low post count even though I have been a member for over three years, I read a ton of posts and only post if I have something usefull to add in order to help or educate someone. Too many people post just to say something or to run up an insane post count while not helping a single person.

Ok, I better stop.

Full_Tilt, are you a mechanical engineering student by any chance? Not that you have to be, but you might want to look into the SAE BAJA or Formula competitions. You can learn a buttload on those projects and it looks awesome on a resume. I was the Co-captain of our team during my senioir year (BAJA). I designed the suspension and did 90% of the construction work with the captain of the team. You learn alot from actually doing the stuff instead of just hearing about the concepts in class. The best part is you will get on the good side of the machine shop guys (if you have one on campus). I still get to go over to the shop and they let me use the machines. I just went over there a few weeks to turn down some used valves to make valve seat protectors for when I deshroud the valves on my head.

I am actually, Im still in my early years so I havent had a whole lot of classes specific to my major, but Im looking forward to doing so. Ill have to look into those programs, Ive heard of them and they sounds very, very interesting. I was actually supposed to be working crew for Scott Lagasea's Busch stock car, but he lost his ride.
Which sucks because that would have been some serious race car engineering experience for me.

OK so back to your original post. I have a set of three of four Supertech 9.5:1 pistons I pulled from my 1.8L motor due to detonation damage to the remaining piston. The other three appear to be undamaged. I probably could have reused them. The remaining three have wristpins too IIRC.

Let me know if you are interested. I'll sell them cheap since they are just taking up garage space. They have very low mileage on them. Presumably you could get just one piston and complete the set. You would also need rods and rings; I reused the rods since they were fine.

wow that's some off topic nutsacking.

I just sold some 01 pistons out of a spare motor that previously was turboed. they were in perfect condition. the rods.... not so much. all of them were slightly crooked.

Just curious Matt, and it is relevant to the thread, what does a set of used 01 pistons fetch these days?

Dang it. I cannot find mine. They might have been tossed but I'll keep looking.

Roberts' Law of Clutter. The items that have been stored for months are not likely to be reused. Conversely, the items disposed of immediately will likely be needed soon after disposal.

y8s, you don't have access to any other 99-05 pistons by chance do you?

Not to bash or be off topic but make sure your new piston weighs the same as the old one or it will through the rotating assembly out of balance. I only mention this because I didnt see anyone else do so and I wish you the best on your rebuild!

If I get a set of pistons I will be checking their weights and balancing them the best that I can. I have already balanced the set I have now and am considering just putting them in unless I find a used set soon.

I have a set here that I'd give you for $100+ship if that sounds reasonable. I just opened the engine up today. Had ~85K miles and made 130HP on the dyno. I'm in South Carolina.

joliveira at sc.rr.com

Edit: WTF. Scratch that. $100 delivered. Where in Lexington are you? I'm right across from Lexington 1 High School.

OK I found the pistons after all. All but one look fantastic. Supertech 9.5:1
