I lol'd at this.
Like I said, I was in no way trying to be harsh. You have no idea how many idiots I have kept out of this site. For those that come and ask for genuine help, and conduct themselves accordingly, I'll offer all the help in the world. For those that come in and act like assholes or 9 year old kids, or better yet, 9 year old assholes, I'll dish out a bit of "pwn" that has run off more than a fair share of useless members, who didn't want to post anything constructive.
I have a nickname around here... Look me up. Believe me, I have been MUCH meaner, to less ignorant stuff. But, for the sake of me being in an awesome mood because I'm rebuilding my DA to be better than ever, after sitting in a building for a year after having a tree fall on it, I'm in an exceptionally good mood, and have opted against going off on the OP.
For what its worth, I'll even offer my $.02 on the topic at hand. What the others have told you is pretty much spot on. If the car is a J-spec imported motor, it won't have a US VIN number on it. Only thing you can go by is the serial number. If there is no paperwork to prove its legitimacy, its not worth the risk. Usually, if the deal sounds too good to be true, it usually is. Would you want to spend $x,000 on a nice swap, only to find out the motor is stolen if you get pulled over. Then, you'll be charged with possession of stolen property, have the motor taken out, get fined (or worse, jailed), and STILL be screwed out of your money for the swap. I know a good deal is hard to pass up. But sometimes, its best to just save up a little longer for a sure thing. Just save your cheddar until you find something that is "no questions asked" legit, and go that route. You'll be much happier. Then, God forbid, if you're motor is stolen, at least you'll have the paperwork on it to prove its yours, so if it ever turns up, you'll have the ability to get it back.
Now, to the OP, on a note relating to your bad grammar, etc. From guy to guy, what Jason (mirrorimg) said is true. If you want good help, from knowledgeable members here, please try to make your posts easier to read. With the kind of grammar in your current posts, you might get quick answers, but the question is, will they be right? 50/50. If you compose yourself like someone who seems, overall educated, you're likely to get attention from more "established" members who have been around the block when it comes to all things Integra.
best of luck to you...
