My Speed6 threw a rod back in October and I have been fighting with Mazda ever since. As the legal bills climb, it makes more sense to fix the car. So, I did some research and I believe I can do it for less than $2.5k (labor included). The dealerships are known to charge more than $8k. Yes, there's a catch.

I found a mechanic in MO that really (REALLY) wants to get rid of a complete MS6 motor for $1500. He's willing to part it and I believe I can get the shortblock for ~$500-700 . The catch being that piston number 1 is scratched. Of course, this is okay because I *probably* have 3 good ones (I shut my car down immediately when it threw the rod). My motor has 11.9k on it while the used one is at about 30k. Questions for the mechanically inclined:

Is my Frankenstein setup possible? What are some possible shortcomings?

Is it likely that I'll have to replace to head also?

Should I offer less for the shortblock?

I've also had a mechanic quote me $800 for just a shortblock install (not including the above idea). Does this seem fair?

Any tips on shipping something like this from MO to FL? Seller wants me to arrange shipping.

Thanks for taking a look. Here's some pics of the motor I'm looking to purchase:

ok just because i'm feeling generous and you're totally clueless, here's a bit of advice. pull the motor yourself, take the block to someone who knows how to rebuild engines and have them replace the fucked up piston. get motor back, slap it back in, and voila. i'd be surprised if that costs you more than a grand, plus who knows... you might actually learn something about cars. replacing a motor isn't hard, so sack up.

Get it fixed properly instead of trying to bandaid it. While slight, there's always the slight chance that the pistons/rods/etc aren't the same weight from motor to motor and you'd end up with a half-assed mismatched boat anchor that never ran right again.

A cracked piston isn't fatal - it's something that can be replaced.

Not everyone has the time, tools and space to pull a motor.

It's unlikely that there will be a lot of weight variance as we're talking about two relatively identical and new motors. I don't really want to buy a new set of pistons/rods as the situation is already costly enough.

Edit: and thanks for actually adding some content.

Warranty was voided for DSM BOV and an aftermarket test pipe. Attorney costs make it not worth fighting anymore.

If you do go this route at least you'll have another block to play with/beef up when time allows. I don't think its a bad idea but if your going through the hassle of arranging shipping I'd offer less.

You probably don't have much of a case anyways. Modifying a car under warranty is a sure fire denial from any car maker. The test pipe could arguably raise the boost beyond the factory rated limit... claim denied. Sorry to hear about it.

Have you taken your engine apart yet to see what actually happened? By "threw a rod" are we talking the rod cap came off and the rod went through the oil pan? Or did it just start knocking?

So your plan would be to buy the motor from MO with a severely cracked piston, disassemble the rotating assembly, hone the damaged cylinder, and reassemble with one of your good pistons?

Why not have your current motor rebuilt? Get someone with a Mazda Motorsports membership (or get one yourself) and get the parts at a discount, and have a shop rebuild the engine thats in the car.

Unfortunately, as I did enjoy driving this car, I will have to sell it for a few reasons. My priorities are changing fast and having a car to play with is falling. Also, I want to get out of this while incurring the smallest losses possible! I do, however, want it in par condition for when I sell it.

I think I will offer lower, especially if I am arranging shipping. I really don't know exactly how much something like this goes for as I don't modify cars extensively.

Why rebuild it when there's a hole in the block? I'm basically replacing the part that is messed up.

I've never heard of the Mazda Motorsports Membership - looks like it's for racing teams and requires approval from Mazda.

I've already said that. I'm sure I have the ability to read up on it and do it; but it's not something I know I can do right as I don't have any experience in the area.

well as long as you're realistic about it...

what about buying a bare block from mazda and swap the guts, replacing the rod and piston? that seems cheaper

Seems sound to me. Talk to an engine builder. Shit, you could probably order new bearings, rings, a gasket kit and have a refresh done on this engine without any issues.

Sucks man, I know the pain. It cost me a lot of money to fix my FXT and it was never the same since reputable shops still aren't reputable. Guys could buy shit of them and praise it.

If I were the greatest mechanic ever (you) and didn't have to pay for labor, that would be affordable. ;\)

Purchasing separately - the short block, pistons, rods, bearings, etc. come to about $2800 (after shipping). It's something I am considering if this all seems way out in left field (after I speak to some experienced mechanics - this is the step after "post on internet").

Talk the guy down on the engine w/ the cracked piston. Take all of your bad parts to the machine shop and have them match it up. You should have them balance it, this will be in the $150-200 range and should be done any time internal components are exchanged. Take you will need a new set of rings and all rotating bearings just to be safe. as long as the cracked piston didn't crack a ring and scuff the bore you'll be ok.
I think it can be done for under $2k if all goes well.

Since you already took it to the dealer and have a record of a voided warranty, wouldn't it show up on carfax already? So that will make is harder to sell right? Even if it is fixed.... I say just sell it as is and move on.

Good luck

I didn't know you holed the block. Buying that engine, rebuilding it, and starting fresh is probably the best idea. Maybe with beefy aftermarket rods. Or see how much Mazdaspeed wants for the engines after joining the motorsports program.

The Motorsports program is for racers, including autocross. How long will it take you to get the engine back together? From the membership info page:
 Quote:
If you are building your car.

If your race car is currently under construction, the race results requirement will be temporarily waived if you can provide a copy of your racing club membership card (SCCA, NASA, etc.). You will be required to provide a completion date for the first race you plan to compete in. You will need to provide race results from your first event within 30 days after the competition.


http://www.mazdamotorsports.com/pages/membership.html

You've already voided the warranty, and you've already decided to fix it. What more can you lose by signing up for the program and getting the rebuild parts at reduced cost for the price of an SCCA membership and an autocross entry fee?

i have another suggestion... this one is from interpol's best-selling book titled "the art of scamming people"

step 1: swap in some shitty mazda6 n/a motor
step 2: sell car
step 3: profit
step 4: high fives all around

sorry this is a dick move
I may be in the minority here but if you fuck up a car and just try to bandaid it to get rid of it that's some pussy stuff

Of course if you are going to fully disclose "rebuilt" motor then it's all good

How so? If he gets it back to the way it was before it cracked the piston using OEM parts and everything checks out, how is that any different from any other used car out there?

Is Impulsive a dick for trading a car in that didn't have a stock short block? Do you let dealerships know that, at one time or another, your car was NOT completely stock before handing over the keys? Or that you've taken it to the track a few times and blew the clutch, for instance?

Give me a break...I mean private party is one thing, but if a dealership gives you black book for what they will more than likely send through auction anyway, oh well.

FWIW, mine had a stock OEM untouched Subaru longblock, it just wasn't the one that came with the car \:\) But yeah, you can never have full disclosure on car history since many of us hit the drag strip and have a mod or three. I was extremely honest when listing my car for sale though - likely to my detriment.

In a situation like this, if I was to fire sale the car, I would at least find a solid OEM replacement. That was part of the reason I went with an OEM, assembled longblock instead of swapping shortblocks or rebuilding. Less chance for error, poor work, misc. hours finding gremlins, blowing the engine again in a few more months etc.

Fuck me, it hurt the wallet though.

Ive never done anything you describe above, and yes it's a bitch move to fuck up a car and throw some duct tape and a band-aid on it and try to pass it off as if nothing was ever wrong.

you fuck up, you deal with it, don't make your problems someone elses headache.



ps blowing a clutch and sending a rod through the block are 2 completely different things

And carfax doesnt show when my celica was stolen, in 2 wrecks, had its engine replaced due to hydrolock and my spec-vs wreck even though they were all repaired at dealerships.
