So I bought a s4 TII jsec and opan delivery, found it to be trash. I took it back to who I got it from and he hooked me up with an s5. I just tore into it only to find the rotor housings to be scared and two broken apex seals and one missing corner plug. other than that shes sweet. No but really, my question is what type of tollerance is their for groves or gashes in the house, has any one out their being as cheap as i'm going to have to be and use one of these gashed (scrapped) units. P.S I know what FSM says I want to know if their is some hillbilly way to get it going ,thanks Corbit.

Depends on how bad they are, but if the housing is scarred, it is more than likely trash.

I don't know how bad the scarring is, but since it has broken apex seals, its probably pretty bad. Generally, using scarred housings is a bad idea, and will just cost you more time and money down the road than doing it right the first time would.

Corbit

The apex seal'swere still in place just broke. I took it to Atkins rotor and Dave said it looked like a turbo fin ate it he said that he would not run it. But I'm pretty broke, and really would like to get this thing up.

hybridracer

Youll only do further damage to the engine, which in the end will cost you more money.

Edit
Also if the apex seals are cracked its not gonna run for ****.

So if a turbo fin went, what are you going to do about the turbo?

Corbit

I picked up new Atkins rebuild for it and it appears to have a new turbo on it .

where did you get your motor from?

BigTone

It would be pointless to use a scarred housing. If the apex seals went or cracked, the housing is pretty much useless. Sorry man. Just buy a good used housing, it will save you money, time, and ALOT of headaches down the road.

Get your money back,

Broken Apex seals...ok

Bad Housing:...BADDD

Screw that......Everyone is so hell bent on getting a rebuild, if you are poor buy a used motor for $200-300 swap everything over and say **** it...it'll get you around untill you can afford a $2300 block from Mazdatrix or wherevever.....GET A USED BONEYARD MOTOR PUT IT IN AND DRIVE THE DAMN THING!

Who sold you this motor? Take it back, they obviously are trashed. Mine came with everything, the inside was beautiful! no scraches, minor carbon, the only thing that was worn to any extent was the apex seals and they still had plenty of life left in them, decided to try the rotary aviation ones instead though, my side seals will probally wear out before the apex now

SDrotary-FC

yea where did you get the motor from?

cymfc3s

what i do, and what i recommend alot of people do if they buy JSPECs, is hand turn the motor over with the plugs out and make sure you get consistant "puffs" on each chamber of each rotor. I also take a flashlight and peer through the leading spark plug holes and check the apex seal. If i feel frisky ill remove the exhaust manifold and look through the exhaust port to get a better look.

Um yeah buddy. You have the part about saying **** it right because most likely a month or two later that's all you can do with a dead car.

The engines you got sound like they are for rebuilds only.

If you are getting a Jspec and plan to run it then you need to get compression numbers with it to see what your up against. I'm guessing that engine will only run for a month if your lucky.

SDRotary got me a pretty good Jspec. So far the external parts are nice.

I peeked into it through the exhaust and the front housiong had some topical rust from some water getting in while shipping but the rear housing was fine.

If cleaned out it could probably start up but I'm sending it to Kevin Landers hopefully this week to get rebuilt.

only problem wiith this is sometimes you dont see it till it is delivered to your door. If you mean do this as soon as you meet it, then I would agree.

Ok ^, what you said is the stupidest thing i have read on the boards all week.... ( and i visit the lounge!)If your logic is true then no one should buy a used car because the motor is trash because it is used..Right? A used car has a "used" motor........There is nothing wrong with a used motor at all!!! Don't give me the whole "well it's been sitting there for a long time and the seals blah blah blah....".I took a "Used" motor out of a 81 rx-7 that had 132k on the clock, hadn't been turned over in 5 years put it in another car and ran it HARD for another 100k untill the apex seal finally gave out. Even remanufactured engines MAY only last a couple months, yes they may have a warrantee but many boneyards will give you a 90 day warrantee too.. so Digi7tech stop pretending to be an expert...if you are going to continue then at least post something that has some actual factual merit. USED Motors are a good way for someone without a lot of time or money to get the car running UNTILL THEY CAN AFFORD A REBUILD!

cymfc3s

yah, with most companies that sell JSPECs, they have some sort of guaranteed to not be bad out of the box. So even if it shows up at your door bad, you can still get a replacement sent out.

Damn. You got me. I'm a poser. I don't know **** about Rx7's!!!!!

Where's your Jspec? Mines sitting in my garage. I've stripped the Jspec down to short block and know what they look like.

I had my 88 SE sit for 6 months and it started up like a champ. I never use the sitting for a long time slant. I understand that US used engines have a good chance of still running.

Have you seen the Jspec Nightmare threads?

The Jspecs sit in junk yards usually until they are shipped here. They get abused by weather and then sometimes "cleaned" by the importers to make them look good. Mine seemed to be cleaned or maybe just weather abused because the turbo had rust and a weird calcium like deposit on the turbo and exterior.

As for any used engine unless you can see the car it was in or know the owner you have no idea what happened to it in it's life time. You also don't know the mileage unless you get the front clip from Japan.

There was a guy I met at Sevenstock which had gone through a few Jspecs. One lasted him 2-3 months and another lasted 2 years. It's a gamble with them.
I came across some extra money and decide to go the right way now instead of pulling a engine later.

In the end you still have a USED engine. A Rebuild is going to have a much higher chance for longevity than a Used. You can't debate that.

Bleh **** you and the horse you came in on. Being pissed off at people just reduces your life span.

Check the post-------HE IS BROKE!!!!!! I was giving him a sudjestion about how to get his car to drive, the motor he bought is TRASH! I don't know a damn thing about "jspec" motors and don't care to. All i know is he has a motor that is basically worthless and wants his car to run! I think swapping a JSPEC is STUPID- UNLESS YOU HAVE A TON OF MONEY to do it right. He is looking to Jerry rig it. Can't make a car run great on empty pockets.... P.S. if everyone is having do much trouble with JSPEC motors stop buying them......You don't have to go JApaneese because SUPERSTREET says it's cool. There are other ways to extract 25 HP out of a US spec motor instead of spending $1200-$2500 on a Stupid "USED" J-spec mOTOR. By the way I am not into beastiality so i will not be Screwing the horse i came in on, leave that filth in the lounge. SICKO!

ps.digi- Both your cars are broken bad seals....I have 3 rx-7 that are running...and 2 that are for parts....so while you sit there staring at your cars I am out driving mine.....poser and to check out my life span check this link. I am going to be fine don't worry..

OMFG I have a dead FC I'm am soo jealous yours is driving!!!!!!!
I'll be driving my 88 GTU with a rebuilt TII engine in under a month. It'll have RB DP/Presilencer/CS Single catback/Apex BOV/Redone injectors/Walbro pump and Mazdatrix Hybrid driveshaft.

Don't call me a ******* poser. The only thing I haven't done myself on my cars is a clutch. Which I'll be doing on the new engine. I've even welded the damn diff mount done a PD swap.

My cars blowing seals just proves used cars can go at any time. My 88 GTU went with 102k on the clock and the 88 SE went with 155k on it

The Jspecs have no difference in horse power.
They are cheap cores to get. I got mine because I am doing a Series 4 NA to Series 5 Turbo conversion. It came long block so I have everything needed to swap it.

I live in AZ and there are NO FC's to get parts and engines from so this was a viable option.

Sorry Corbit for kinda going off topic.

I've built my own motors from just used, mix and match what ever gose together. And I'm ceap,what ever it takes to get a piel of used motors, Like Johnny Cash and his Cad. A long the one way one picks up tricks to get by and one to just sand out the scores in the houseing by useing a cly of 2'' warped sand paper, yep the crome gets thin but then I'm only going to the drags

YOUR WORDS NOT MINE.....SLick...

Corbit

ah yea anyways BRO'S I am broke but not broken I'm taking a trip to the dude I got it from and I'm going to get some money back or another motor cuz this is bad ****. he did give me the hand shake warrenty ,so I'm sure it all be good if not we'll see how he like a rotor up his ***. After futher examination of the rotors it looks like one is as fd. I could be wrong but it has the groves on the rotor and the other one is smooth hey thanks for your input and you 2 are on a time out.

Corbit

anyway I talked to the guy I bought it from and he said he'd tighten me up fro a housing. But the rotors have a few scratches or gouges in them ,how critticle are sratches Atkins said I could sand them down that sounds great I was just wondering if anyone has done this thanks Corbit
