jdm motors any good?
iv been looking into swapping a jdm TII motor and tranny into an N/A....does anybody know anything about these jdm motors, they seem pretty cheap and come with warranties, also are there any considerations i should think about for the swap?

You may wish to use the search function next time. It is found in the upper right hand corner and can help you find threads like this that have been covered quite a few times.
The long and short of it, is that most Jspecs have been sitting in Japanese Junkyards for 12+ years now and getting a decent one is a crap shoot. Getting a decent one that drops in and works perfect for more than 6 months is even more unlikely.
The upside is that generally the are great for rebuilding. After being rebuilt they can last years.
As far as swap info please search on that. It has been covered to death. There are links on this and other information found in the FAQ for FC sticky thread at the top of this section.

Starting and running well enough to drive on are 2 different things. I've bought 2 Jspec engines in the last 8 months. One ran like a champ until it threw a seal 4 months into it. I never even pushed it hard. The next one I bought, I could tell would be trouble. Putting a finger into the exaust port, I felt DEEP scratches in the housings. DEEP. I'm rebuilding that one and the previous one now, hoping to assemble as soon as my oil seal springs come in. BTW, the only reusable parts on the last one were the irons and one rotor. Both housings and one rotor were not usable. I did get a partial refund from the company because of this, but it was just a huge pain in the ***....

well I got my motor from www.japanmotorimport.com and it's a good motor, nothing was broken. The total was like $1175 for motor and tranny. The only thing I didn't like was the metal shards in my turbo from them chopping off the downpipe too close. But it could take a dump on me down the road who knows.

why is it when someone asks a question you idiots want to jump all over them for not searching on it why do all that when someone new may be on and have different things to say about the topic and if you dont want to give an answer there is nothing wrong with hitting the back button and let somebody else give an answer geez not everyone wants to search for an hour its better to just ask and see what they say
next time just remember the back button

First, nothing like crapping all over this guys thread. Next time PM someone if you are unhappy instead of side tracking his or her thread.
#2 I answered his question as well as pointed him towards being able to help himself.
#3 If you have a problem with answering his questions (which I guess you do) as well as telling someone how easy it is to help themself, you should perhaps find another board.
One where you can be a stupied as you want and ask all the dumb questions you want. This board is for actually helping people; helping them by reading past posts and present ones.

Keep Right Except to Pass
Gosh, I certainly hope this isn't considered hijacking or crapping on the thread.
This got me to thinking about something. I've alway's assumed that the majority of the jspec/jdm engines were virgin factory engines. You know, factory built, run to whatever limits the Japanese bureaucracy have determined, then pulled and sent to the other markets. The last one I installed seems consistent with this as it's in great shape, just worn more than I would think 30k mi. would indicate (85psi).
One flaw in my theory I've already come up with. They must keep some or what would the rebuilders do for cores?
What does syklone's second engine tell us? Was it just my assumed virgin engine that was chunked in Japan and sent to us or was it a rebuild with nasty housings?
I don't know. What do you guys think?

CosmoTT, you're new, so unlike you may not be fully aware of Mark's massive contribution to this board and the wider rotary community. Take my advice: shut up now before you make even more of a fool of yourself, particularly if you hope to get help or advice in the future. Perhaps you should go read the FAQ too, and also the sticky entitiled "ATTN NEW MEMBERS, Read here before posting". Those threads are there so that frequently asked questions like this don't take up valuable space.

Here is my answer to that.

In November I ordered a JSPEC motor from Japanstarmotor. I've done my searching and realized that no one has had a problem with them. I paid $1000 for motor+tranny shipped to my door. I had the motor in 2 days. I wanted to do the misc tuning. The motor was drained of all fluids and was not seized when I received it. Dude told me he would warranty it for 30 days and pay for return shipping if motor did not run. It (by chance) came with a Blitz BOV and a OS Giken Twin Plate. Neither aftermarket part was removed. To make a long story short. It fired right up and I have not had one problem with the motor or tranny, turbo is great and compression is great also.
Keep in mind one thing, this is MY experience and not everyone will have the same one. I say go for it, and if you are worried about whether if it will start or not, send your motor to Kevin at Rotary Resurrection. He will definitely rebuild that badboy for the best price. It is a hit or miss risk you have to be willing to take. But the way I look at it, if you pay the money, you can have your self a great running motor for $1000 (if it works) or a perfect rebiuld w/tranny for $2000 through Kevin.
Those are my 2 cents so take it for what it's worth and how you want.

The reason J-spec motors have such low mileage is simply because people don't drive their cars in Japan as much as we do in America. Gas is expensive, maintenance is expensive, theres bad traffic in the cities, and there's an excellent public transportation system.
The countryside is different though. There, many more people have cars, and the lack of a tightly-woven train and bus system makes driving more nessicary.
Hmm, Japan Star Motors and Japan Motor Import... I'll have to keep those in mind if I end up getting an NA.
