anybody else have replacement engine sites?

They are not "new" engines.
It sounds like you're looking at imported J-spec, used engines.
Like with anything used, you take your chances.

^^^ What RETed said. You're going to end up having to rebuild 99% of the time. If you want a new or already rebuilt core, it's going to cost a lot more than $1,000.00

Yeah, but roughly 35k miles surely cant be in horrible shape......COmpared to my 210k.:beatdeadhorse5:

i cant remember who it was but they went to tigerjapanese that they went to to get a motor and had the ability to do a comp test and out of something like 15 engines 12 were blown.... low mileage dosnt mean jack.

IMHO DO NOT DO THIS get a rebuilt motor from a reputable vendor on the site it WILL SAVE YOU MONEY in the long run.

a buddy of mine did this used j-spec once paid shipping through them and all got the motor shipper needed shipping cost... and then the motor was trashed on top of that so he eneded up with a blown motor and then paid double shipping....... but hey go ahead everybody likes the lottery take a gamble you could be the million dollar winner :)

JDM are not new motors. This is really one of my peaves, people come in with blown motors and they say that they just installed a new motor. This relates to MANA rebuilds or JDM's. The problem with jdm motors is that they are sitting for who knows how long when pulled then they can sit in a container on a ship for 6 months. The worst thing for a used round motor. Just about every one that I have taken apart has been pretty beat up internally. I will only warranty labor on my motors.
As you said though, a 35k core is better than the 210K, that motor is a good mud anchor. Will not be much of anything in it that will be useable. That is if you are one of the lucky ones as proz07 states.

rebuild your motor. Send it to RotaryResurrection or buy one of his GOOD motors to drop in.

If you're GONNA buy a used motor get it off a car that RAN not a motor that set for who knows how long

They comes out of junked cars.
Some of these cars were wrecked due to accidents.
Some of these cars blew their engines - that's why they were junked!

...then...

These motors sit around, sometimes outside in the rain, before they get shipped over to the USA.

...then...

These motors sit around, sometimes outside in the rain, before they get sold to some schmuck like you.

You take your chances.
"Low mileage" don't mean jack when rainwater gets inside the engine.
Yes, that's right - some of these engines sit outside in puddles of water.
Don't be fooled by the super clean look just by eyeballing the engine on the pallet - these engines have been pressure washed and sprayed with clear coat (paint) to make them look really pretty.

i have personally seen some pretty bad off engines from importers.

[rx4ur7]

What part of the country are you in? I build those things also. But with over 200k like I said you will be lucky to get an eccentric shaft out of it. Especially turbo motors. Out here they are near replacement spec at 120K. That is why I recommend new housings after 100. I do not think it is worth all the time and $$$ for something that is going to start loosing power driving out the door. Unless you just want to get it running to sell. There are a few places you can buy 1200 rebuilds but that is what they are. If you have priced the parts you know that nothing much has been replaced. Anyone can throw one of these together and make it run, for a short time. Any reputable builder is going to be up there in price. I think just about everyone on any forum will tell you, "you get what you pay for."
Apex seal lands are probably spladed and out of specifications. Rotors will not be usable unless you spend the bucks to have them oversized to 3mm.
Count on all 5 housings. All seals, two rotors or modification. (At least you should be able to find a couple of decent used rotors), oil pump, chain.
Front cover, oil pan, flywheel, front shaft bits and hardware will be the only things that will be salvaged.
If you want something to last and be reliable, bite the bullet call Ray and get all new housings and seals from Malloy.
That is how I am doing new builds now. Because the markup is not really great I give the client a list and have them buy all the big ticket items if not all the parts. That way I do not have to deal with the paper work, charge and then pay sales tax. Makes it easier to go for some port and intake modifications also.

The engine I put in my '86 was from a guy who bought a JSPEC engine for $1200 to put in his '88 turbo. It worked very well for him (good compression, not dirty, no vacuum leaks, ran great right out of the crate).

I rebuilt his old engine for $750.00 (Including purchasing the engine) and have had very good success with it.

At the same time. Every one has their own limits and acceptable practices. I highly doubt that any reputable rebuilder would have re-used the parts that I did in my engine. I would never have re-used them in someone else's engine.

[rx4ur7]

That was the exception JSPEC from my experience.

[classicauto]

Generally speaking, the only thing a JSPEC is *any* good for is getting a rebuildable core.

Or at least, will have a few parts you can use combined with whatever can be used from your existing engine if you're after a floor sweeper that will run for a while.

I have had some decent JSPEC's that I've rebuilt though. Never ever bought one and installed it straight from the importer. And also NEVER EVER EVER. EVER. Buy a used engine (especially rotary,....) online. For the love of god if you want ANY chance of not wasting your money on it, pull the plugs, spin it over, go around it with a fine tooth comb and pick the best one that the importers in your area have (yes, go to more then one)

Rule number one about these things is never buy sight unseen.

[NoDOHC]

I agree with ClassicAuto. This guy I was talking about took a road trip to a import engine warehouse and picked his engine out. He did have it shipped to him (because he doesn't have a pickup truck to haul the engine with), but he hand-picked it.

He did tell me that it was the first S4 turbo in the entire place that he found (there were not many S4s, most were S5s) and he compression tested it and all was good (so it's not like he rooted through 15 engines to find a good one).

eBay is not a good option for engines, they take a "representative" picture of a nice one and then send you one that looks like it was dragged behind a train (I'm talking broken mounts, oil filter pedestals, spark plugs, shifters on the transmission, etc.)

I have not personally purchased one, but I have heard horror stories from several who have.

When you said JSPEC engine, I didn't realize that you meant eBay JSPEC engine.

EDIT: I did actually buy an eBay JSPEC Transmission once. That was the worst Idea I ever had. It had bad synchros in every gear and bad counter shaft bearings.
