Piston Swap
Hey guys, I am thinking about going with forged pistons. I called my shop and they said it would cost about 1800-2grand. Not including the parts. Obviously I would grab the parts from a vendor here. They did say however if I wanted to install a new clutch at this time, or stage 2 axles, they would do it for free since the parts would already be off the car. I'm not really sure why the axles would be off for the piston swap, but...whatever works. They said the machining part would cost about 500 since they are going to hone it and balance it and then the rest is labor.
Do you guys think this is a reasonable price? I was just getting an estimate, its pretty rough, but I can't do the work myself, so I need to have someone do it.
*I broke my back in a car accident, I don't have the tools and I don't have the knowledge, please don't tell me to do it myself.*

im wondering that same thing about the price, sounds abit to me though. And if im not mistaken they have to pull the engine out of the car to do the pistons so the clutch and axles would be accessable

well that sounds a little bit higher than normal. id say about 1500 would be right. if they're gonna bore, balance, port, and the entire engine and install the pistons then it should be right around 1500. thats what i've seen other people around here talk about. but if they install a clutch, then 1800 wouldn't be bad.
and yea, i understand on not doing that yourself. i wouldn't either. too much can go wrong.
dont forget you also gotta get pistons, rods, and head studs.
thats around 1200 bucks or so. clutch can range from 600-1000 depending on which one and you need the flywheel too.

swapping pistons is a 8-10 hour job , if your just swapping pistons . so even if they charge you 100 dollars an hour like the dealership its still only 800-1k your getting robbed. and if they are your shop you should get a discount so i have no idea why they quote you 2k , find a new shop. clutch is 500-800 dollars if your gonna get bored and get a clutch done and all that other stuff then it makes sense but if your just swapping pistons its too high.

Yea they said they would install a clutch/axles and anything else that I wanted for free since the parts would be out of the car anyways. Yea I believe they are taking the engine out, since there going to get it honed and balanced. I was also thinking about putting on new valves and springs for the head, so that revving higher wouldn't be a problem. But if I do that, I will want to port the head too. All of this is pretty pricey though, and I don't know if I should just skip this plan and go straight for the turbo! Although, if I did do this, I could run a 100shot no problem =D.
Thanks darkmanx, it was a really rough quote but that was for the machining+labor. They have been my shop for a long time now and they are really good guys, generally they give me great deals and free installs etc.

are you going with a higher or lower compression ratio? if not you should have to hone out the cylinder and thats alot of money and in my opinion with all that done i dont think your gonna see the power staying with the charger, def. go turbo too actually use what you just dropped like 4g's on, thats just my opinion

I haven't spent any money on the pistons/install/turbo kit yet. This is only an idea running through my head. I was going to stay with stock compression. I realize that I wouldn't be seeing much over 300whp without head work on the m62 without spraying, but a 100shot with forged internals would be nice, and hopefully help me reach 400whp.

well iam pretty positive the diamond pistons fall right into place and connect right to the rods, iam staying with the stock compression ratio, IMO not really needed to change cuase iam shooting for 350-400hp, i dont like spray, "cheating" i think. id go turbo if your going to spend the money good luck hope to hear about the progress

How can there be cheating in making your car faster? That's like saying a power adder is cheating, so your turbo is cheating, my s/c is cheating. That's a really stupid statement in my opinion, adding power isn't cheating.

A slight hone is recommended for two reason.
1. It removes any scarring or damage to the cylinder walls.
2. Forged pistons will expand more, causing increased wear on the sleeves.
Now, you don't absolutely HAVE to, but it's a good idea. A hone shouldn't cost you more than about $50 per cylinder. That's obviously not including the rest of the labor in taking the engine out and R&R.
