OEM Engine Block

[orangeade]

Hey guys, just have a quick question. Wondering if a new OEM block can still be purchased from Mazda? I can't have any downtime with the car to rebuild my motor so would rather start with a fresh block to start my journey down the forged path. Thanks in advance.

I don't see a reason why not. But then again, I'm sure a call to Speedcircuit or Corksport would yield the same results.

Why not source a long block from a salvage yard? You are forging the motor right? The heat treating a used motor gets from use will help keep the block from warping.

Agreed, just rip. One out of a regular protege/p5, save urself some $$$ and rebuild from there or just order a built block straight from speedcircuit.com

ya dont waste ur money. Call around see if a junkyard has a used one. Mazda will guaranteed **** you on the price.

Thanks for all the responses. I didn't get a chance to call Mazda today to see if and how much. Was looking at the speed circuit site last night and it definitely seems like a viable option however wanted a bit of a project to take on over the winter months to build from scratch. Although in the end I might just go the speed ciruit route. I'll also give a few wreckers a call. There's got to be a ton of P5's kicking around.

Now above there was something mentioned about a "long block".....is there a different motor in these cars? Short block?

A "Long block" is a term used as an already assembled engine, crank, rods pistons, head, cams... almost complete

a "Short block" means just the bottom end alone, block crank rods and pistons... no head

thanks for all the info guys. ok, I did call a local Mazda parts dept along with one in the Seattle area. In case anyone else is wondering I figured i'd share the info I got.

Vancouver: Block alone $5300 "Long Block" just over $10,000!!!

Seattle: Block alone $1648/$1685 I didn't ask about other options. He couldn't tell me the difference between the two available blocks but said i'd need to figure out a part number for him to tell me which block is right.

additionaly I asked about the Factory Service Manuals:

Vancouver: $199 + $85 for the electrical

Seattle: $300....couldn't tell me if it included electrical or not.

I'll call around to a few wreckers to see if I can find a low mileage P5 and see how much to go that route......however, does anyone have the part # handy of the right block so I can confirm with the Seattle parts dept. Thanks again!

And I think we have a winner. Found a motor with 63k miles on it for $500. Now on to the other fun bits.

There is a How to Forged Motor that might help with some ideas...

 

[orangeade]

Sweet! Thanks for the link. Very helpful!

 

[BRIAN_MP5T]

It is incomplete..and requires to be updated...

The new motor used ARP studs vs the OEM. They torque differently.

Ask me what you want to know. in the future

i work at a mazda dealership and i priced a block... all i can say is if your getting a NEW oem block (wow)u have deep pockets... REAL DEEP my price is 10% over cost and a BARE BLOCK is still wicked expensive. get one from a junk yard and have it haned/checked.. much cheaper, just as reliable.
