Took to a family mechcanic. Now it spudders, the blowoff doesnt left off.. boost is..
It starts up right away. The idle is from 1,000 rpm to 2300 rpm, and when i try to throttle it suppers JUST a lil bit then the turbo hits and it takes off, when i left off now the greddy blow off downs left off the preasure with no noise, it use to be very loud, and i hear it release very slowly.
what he did was take off my turbo, replace a oil ring there because it was leaking coolant.
removed the exhaust, put a new starter on.
i just bought this RX7 and it ran great, now ive lost my blow off and it runs like ****. This mech seemly is good and it would be the type of guy to put it back together just as it was.

i will check the vac lines tomorrow. Anything else i should look for? Would back preasure be a problem. he remove the down pipe, can cat. and the cat was real rust out and doing 140+ at 22 psi really put some heat down it more then enough times.. I dunno if that would have a factor seeing it ran PERFECT before it came in. Just had a leak from the O ring in the turbo manfold. He replaced both. It was leaking coolant. now it runs like .. well ****, unless i floor it and the turbo forces it to go but it feels nasty, and it wont ride smooth at low rpm speeds. I just bought new NGK's for it to. It has a custom intercooler system

I do have a Greedy boost controller. and he replaced my starter... and the seals that's it.
i wish it was leaking coolant like before and he had never touched it. I have a $502 invoice.

Do you have emissions equipment still on the car? Check all the vac lines, it sounds like he left one off. I would start with the blow off valve, I bet thats your problem.

Anyone have a picture or idea of how my vac lines should look from my blow off to the motor?
again the turbo manfold was taken off, and put back on, now car runs like ****, blow off barely lets off.

First things first: get a refund from the mechanic. He broke your car and now you have to spend time and money to fix it.
Second, check all vacuum lines in that area. Start with the line to the FPR, and the one to the pressure sensor. Make sure the TID is installed correctly and not creating leaks.
Third, 22 PSI?! On what turbo? On the stock ECU?!?

the car is running better now, the only problem is the blow off vavule will not blow off! it just barely releases it and my boost guage just tidders down when i let off like its barely letting off preasure, and trying to drive it real slow is almost impossible. I checked the vac lines...

Is the blow off valve getting a good vacuum source? That amount of boost is way out of that turbos efficiency range. You should really dial that boost controller back before something breaks.

i run the boost at its lowest, the greddy gauge never goes over 0.8 - sometimes i put it on high boost and it goes to 1.0 . trying to keep it at 8 psi max.

Ok, I call shenanigans. First you say that you were running 22psi. Then you say you are running .8 bar..... thats a big difference.... really really really really big difference. And there are no O-rings on the turbo manifold. And you havent checked all of your vac lines, ALL of them. You are experienceing a vac leak, same thing happened to me. Find it, fix it, woosh.

I am going to try again tomorrow to check the vac lines. and no its not the stock ECU, i don't know what they have it setup as. I didn't do all this work. So its hard for me to know how they have the vac lines set right, and the HKS blowoff directions i got with the car are 100% in japanses. ...
I wish i could see a pick of how it should look.

Your story has some serious holes in it.
348 RWHP at 14 PSI on a stock turbo? Not possible. 348 RWHP on a stock turbo isn't possible at all.
22 PSI is a ridiculous amount of boost and probably makes less power then 12 PSI.
If your BOV isn't BOV'ing, then simply check that the vacuum line is connected to a vacuum source after the throttle bodies. Check the adjustment to see if it isn't too tight. Finally, is the turbo even making boost? 22 PSI and the stock turbo won't last more then a week.

F**K THE SYSTEM!!
The BOV is suppost to have a hose attached to the nipple on the BOV!!..
ALSO. U should check that all hoses/nipples on the compressor side of the turbo are hooked up. ANd go GEt your money back from your "mechanic"

all the vac lines are tight and not leaking.. I guess its just hooked back up wrong. But the car is so modded and all the stock parts and emissions have been taken off and the greddy boost controller is hooked into the lines.. I am lost on what todo ... I have noticed if i take the line off the nipple of the BOV the intake shakes like its blowing off through there, ..lol.. wow.. So I have been advised to take it to 2fastautosports.com they are close and i talked to them on the phone.. $35 an hour... but I am scared Ill mess my rx7 up more.

Not really that complicated man, just do what Aaron said and follow the line from the BOV to make sure it goes to a vac source after the TB. If all the emissions are gone then it should be even more clear. You could probably post a pic and we could tell you if the BOV is hooked up correctly to rule that out.
