    Used engine from Japan?

    I’m not sure they even normally have engines, I may have just gotten very lucky. But here’s the seller just in case. https://ebay.com/usr/oemtradersintl Sent from my iPhone using Tapatalk

    Used engine from Japan?

    Yeah I thought so too man! It was so good that it had me worried but luckily it turned out to be legit. I had a shop that specializes in racing miatas do swap for me since I don’t really have a place for a job like that and even he was amazed and said he was going to contact them to see if they...

    Used engine from Japan?

    I looked and looked and was seeing a lot of $4,000+ prices. After a month of looking non stop I found a ebay seller that purchases warehouse overstock or something like that. Anyway he had a brand new long block still in the factory mazda crate. Ended up paying $2600 including freight. Sent...

    Used engine from Japan?

    Well it was a long road but he’s back in business! Brand new oem long block installed. New clutch and all the other stuff that made sense to change at the same time. Now he can finally enjoy it! Sent from my iPhone using Tapatalk

    Verify oem long block

    Nah not this time. It’s my sons first car. He will have to settle for stock power for a while. Think I’ll save the old motor and him and I can tinker with it and maybe build something over time. But for now, we just want it back on the road. Besides I can’t have him driving a faster car than...

    Verify oem long block

    Awesome. Finally something has gone right with this car! Lol seems like I got a pretty decent deal too from what I’m seeing. Ended up getting it for $2500. That’s why I was skeptical, it seemed too cheap honestly since used motors were practically the same price. But looks like it’s legit.

    Verify oem long block

    Can anyone tell me a way to verify the new oem long block I’m getting is actually what it’s suppose to be? Just wondering if there’s a difference in the speed3 and regular 3 long blocks so I can verify.

    Used engine from Japan?

    I ended up getting a new oem long block. But I’m wondering can anyone tell me a way to verify it being a motor designated for the speed 3 and not the regular mazda 3? Or are they the same?

    Used engine from Japan?

    I def agree, but I’m pretty sure the motor was toast when we bought it. Only put a few hundred miles on it. So it’s hard to base it off what happened prior to us. It’s obvious it wasn’t taken care of.

    Used engine from Japan?

    He said they don’t do a stock rebuild. Just built motors with forged internals etc. real nice guy though.

    Used engine from Japan?

    Thanks! Certainly sounds like a good company to deal with. I checked out there reviews and fb page. Unfortunately it looks like he’s 2-3 months backed up. I’ll reach out to them on some pricing. I don’t suppose you know what the stock rebuilds are going for do you?

    Used engine from Japan?

    Yeah man I slapped some rod bearings in and it ran absolutely perfect, but only for about 2 days. It never dawned on me and I feel stupid but now I’m sure the oil pump was prob full of metal or something crazy. So I have a hunch the oiling was compromised as well. It’s not “knocking” yet but...

    Used engine from Japan?

    It was a pos when he got it, of course we didn’t learn that until after the fact. Looks like the motor has been gone through by many people at many times. Rt now the rod bearings and crank are toast. Metal in the oil so I’m sure the oil pump and many other parts are damaged. Yes I could pull...

    Used engine from Japan?

    So unfortunately I’m in the market for a replacement engine. Bottom end is trashed. My 17 yr old son just bought it 3 months ago as his first car. Just trying to get him back on the road. I see a lot of used engines from different jdm sellers saying used from Japan with 55-65k miles. Anyone have...

    Do you know what this is?

    Glad I took your advice, ended up finding 2 more bad out of the 4. Crank wasn’t great on 2 of them but the shoestring sanding/polishing made it a lot better. Just buttoned it up this evening (took a break) and let me say it runs better than it did when we bought it! Idk if the Vvt can cause...

    Do you know what this is?

    Thanks man I appreciate it. Now my dilemma is do I change all the rod bearings or just the one and save the other 3 sets for replacing that one again if needed. I’ve only taken the one other cap off and the bottom half of the bearing and the crank looked fine on that one. The other 3 uniformly...

    Do you know what this is?

    Very well could be the case. I’m re-installing the balance shaft so I’m just glad to know it doesn’t seem to be a needed part. The reason I’m in there is because of a rod knocking. Vvt was bad and it starting knocking as he turned into the neighborhood. Been parked since. Did the Vvt not...

    Do you know what this is?

    Well I did just replace the whole Vvt set up so who knows. It does look just like the pic Johnny posted though.
