Where do u guys recommend to get J-specs from? I preferably want a company that has some type of guarantee and maybe a comp. test. The oil seals are going on my car, so its time to get some real power. I'm also going to order a haltech, a walbro fuel pump, and buy a TII w/ a blow engine, that way i can yank the other **** i need
|
Maybe http://www.fc3s.org and http://www.corksport.com .
|
if you are going to go for a good turbo and computer, why not do it right and buy a T2 and port the motor? I know it is more expensive but you will have a good motor with more pwer when done.
|
Um, if he puts the T2 motor in his car, he'll have a motor that is just as powerful, lol....
...Also, after my ordeal, I DON'T recommend a Jspec. I mean, I got mine from FC3S.org, and I am not at all bad mouthing Dave Gibson, or his associates there...they are great, but the vendor they get their motors from say that the motors are compression tested before shipping out of Japan, and they are tested again when they arrive to California, HOWEVER, if this was true...my motor would RUN!!! Also, since I took about 4 months to put the motor in the car, the vendor wouldn't honor his warranty, so I'm stuck w/ a $1K motor that doesn't run! So anyways...if I were you, buy a blown T2 motor for like $300 to $400 and just rebuild it, then transplant that...its way less aggrivating, and its what I wish I would have done in the first place.... |
Now to only find a blown TII motor for $300, or even a TII parts car for that matter.
|
I see blown '87-'88 T2 motors for under $500 all the time....sometimes its just the block though. Thats the only problem, you'll still need everything else. However, if you wanted to, for about $1200 you can convert to a carb setup, and not have to worry about swapping your ECU, harness, or anything like that...you won't even need to buy most of the other T2 stuff to go w/ the motor. I mean, think of it this way....$1200 to convert to carb and less headache, or over $1200 for the haltech...its your call....(personally I still prefer fuel injected)....
|
i have considered just buying the blown TII, but if i can't find one i'll have to go J-spec. And rx7s are rare up here in MN. And i plan on doing the transplany because my 7 is cherry and i spent too much to get it that way.
|
My j-spec had 120 psi on both rotors. From fc3s.org.
Rotaryman's ordeal is pretty crappy, yet I still have to recommend fc3s.org. Getting a j-spec is like playing russian roulette, methinks. Mine was a good one, but you never know what you'll end up getting. |
J=specs are like a box of chocolates

i'll give you guys getting jspecs the same tip i gave turborotor that prevented him from installing a blown jspec into his car. all you have to do is pull the plugs and spin the flywheel or front eshaft bolt. you should hear loud even whooshes. if you get whooosh.............whooosh........ that means one rotor is gone. that is how i determined for sure my TII engine was dead https://www.nopistons.com/forums/pub...IR#>/smile.png

you mean having no apex seals makes it easier to spin ? :P |
Do what Vosko says, I did. It is a great way to tell if you have an apex seal amiss. I took out the plugs in the front housing and had my mom bump the car over with the FI fuse removed. You could hear each seal go by: swoosh, swoosh, swoosh etc. Then I put the plugs back in and took out the ones in the rear housing. It sounded completely different with only one definite swoosh since one toasted apex seal caused loss of compression on two of the rotor facings. I started tearing apart the engine after that. I think you should take that refund money and put it towards rebuild materials. This way you can port the motor or do whatever and get a good look at internals that might need to be replaced. Sucks you haven't driven your car for 4 or 5 months though, I can't waite to see the SEX machine tearing it up!

Yea, I wasn't trying to dis FC3S.org...I'm just saying, be careful. When I got the motor, it was pretty easy to turn over w/ the flywheel, and I sensed something wasnt right, but Dave said that the protectant they put in the motors can sometimes stick and it'll take some ATF to free it up. I mean, he was right, I had no compression on either rotor when I first installed it, but w/ ATF...the front rotor freed up and has great compression now...but the rear rotor is a bitch!!!! Oh well, I was only using the Jspec for a quick fix, I was planning on porting the thing anyways.....

Sorry, I couldnt resist. Im still shaking my head at some of this rotory talk, and I have had a RX-7s for about 8 years now. Good thing they are reliable - - did I say that out loud?, I probably cursed myself now ! :ph34r:. I edited it, I took the word **** out https://www.nopistons.com/forums/pub...#>/biggrin.png
