Does it seem to you that buying a j-spec sounds too good to be true???

Has anyone got one for their FC and had total horror stories about it???

I know they have warranties, but still it sounds too good to be true.

You just need to remember, it is a used motor. If you expect some surprises, it's not so bad.

I have seen some Jspec motors that looked like they had 100k miles on them and I have seen some pristine as if they had only 3000 miles on them.

Luck of the draw.

They last one I got was very clean inside, and although I could have used the same seals again, when I rebuilt it (I wanted to make sure it was perfect and didn't have to drop it in asap), I used fresh and returned the motor to like new factory condition.

But I have seen them just plain bad, that there was no way the compression test was done.

Just luck of the draw.

why buy a j-spec,,they are no different than american ones from what i have heard,,,if i am wrong tell me why so

ponykiller

Buying a Jspec is good because Japanese car owners must replace the engine after it has so many miles. This means that the wrecked cars the engines are being pulled out of shouldn't have excess (I mean over like 60K) miles. But again, it is luck of the draw.

I will be ordering one from FC3S.org this march. Hopefully I will be feeling lucky!!!

you have to remember, the j spec engines just sit out on the ports waiting to be shipped, so if it rains all the water and stuff gets in them.

water and stuff gets on your engine anywat, just make sure it was sealed right. JSpec sound too good to be true b/c its from Japan and they start out w/ way better cars than here, its like the old muscle(sp) cars, the ones that came stock w/ 400 or more HP and the BB Fords, Hemis, and Chevys. Same idea just newer motors, we would have all the cool JSpec stuff if there wernt so many tree huggers here. stupid emissions.

I don't know how this ever got started, but why do people believe the engines have to be replaced after a certain amount of miles in Japan? This is not true. Not even a little bit. My car had over 160k kilometers on it's original engine.

i don't think its that you HAVE to get a new motor after a certain amount of years...but from my understanding that if you keep a car an older car for a few years your insurance (and taxes possibly?) on that car go up. so maybe most people don't wanna bother and just get a newer car...at least thats what my gf tells me, straight outta Abiko, Japan

i put in a turbo j-spec, found out a month later it was corroded internally, leading to failure of the housings. Oh, and it didnt have a warranty.

You can buy them from www.Corksport.com I know.

i heard that in japan they have to replace there engine very 30-40k miles due to smog or insurence or something. i wouldn't recommend a j-spec because we all know that they have like 30k miles on it so the motor was not maintained. probbaly the guys in japan say" the motor is coming out anyway, so why change oil and baby the motor?" they probbally dawg the *** out thier ****. also there cars run on like 110 octane all the time and ****. thats just my two pennies.....

Erik

lol...riiiiiiiiight...so you were born and raised in japan right? and know their habits in and out right?

fLyiNgOuFeR

no i don't. i didn't say i did. i said that was my $.02. so thats just my opinion.

soul assassin

well your opinon is your opinion but that is not true, and yes i live in japan

Uh oh, the man finally stepped in to lay tha SMACK DOWN! Hey soul assassin, so what is the deal on the engines in japan? To my knoweledge, I thought it was required by law(emissions crap) that yall had to replace the engine at 30K kilometers.

soul assassin

not true, you can keep your car and engine as long as you like just have to go ge it checked every 2 years (jci) insurance thats when they look at the whole vehicle from bumper to bumper, but they also have under the table jci which is what i do, since there is no way in hell my **** would pass emmisions! lol

I got burned this year. Bought one and it took me so long to get it running right it only had 4000 kms in the car before it failed one week out of warranty. I think it was already screwed or on the brink when I got it and that's part of why I had such a hard time. But lucky me they gave me half price for the next one. But ohh noo I'm not bitter. You'd be better off (in my humble opinion) to get a rebuilt one from Mazda, which was 2250 CDN as opposed to 1800 CDN for the jspec which REALLY cost me 2700. I don't think the actual shortblock is different but the vacuum lines and some other stuff was. I know what I'd do if I had to start over.

PSIGOD

well my jspec just came in and the mechanic is putting it in of tuesday so I will let you all know first hand if they are **** or not. Lets just hope that this is a good one.

Jerk_Racer

WTF, am I writing to myself here? I can't say why so many engines come out of Japan on a regular basis, but it's not because they are required by law to replace them at certain intervals. Like soul assassin, many dudes over there that tweak there stuff get their shaken taken care of via the hook up system. The other drivers that don't pay for the hook ups do get reamed on the bi-annual inspection. But replace the engine every 30k miles or so no matter how good of shape it is? Think about that for a minute and realize how crazy it sounds. JSpec rotaries are a crap shoot. You might get burned, you might not. Most guys I knew over there ragged the hell out of their cars, but they also maintained them all the time. Many times when I call up old friends they are usually elbow deep in grease taking care of stuff. I worry about the engines that come from people that never maintained their car as they should have.
So far I know one person that has bought a "JSpec" 13BT. He got it through corksport.com and was pleased with them. He still is working on this project so I have yet to see it in action. It should be good considering what he has done so far.

I purchased a J-Spec 13BT motor from Nippon Motors in CA 800-416-3626 for my 87TII. It took a while to get it running right, because a lot of vacuum leaks. Runs strong, has 85psi on all three sides of each rotor. This was done without the throttle blades at the WOT position. I paid $650 for the motor and $150 for shipping. It came with everything from Intercooler to oil pan.

What I would recommend doing is having everything ready to install when the motor arrives. Have old motor out and all new gaskets, vacuum lines, injectors seals etc, ready for the new motor. This way you will have more time to run the motor under warranty. Maybe even try and do a compression check before install.

I am still having a hot start issue, but I have ordered the anti flood module and hope this will cure the problem without the need for a fuel pump switch.

People buy j-specs becuase they are fucken cheap. Thats it.
If everone could afford it we would all have rebuilds built out of all new parts for the perfect engine... But thats too expensive.
With a j-spec you get a whle long block for under $1k and can probably make back at least $200 selling the parts you take off the short block.

SpeedRacer

www.fc3s.org also sells J-specs
