I had boost for a hot minute and now it is gone!!!!

[theboz]

I just rebuilt my stock T25 and it boosted just fine until I drove it. I rebuilt my motor as I had a bad piston. While the motor was out I rebuilt the T25 as it was starting to smoke. I put everything back together and turned the car over for a few minutes until I had oil pressure to circulate oil through the motor and the turbo. She fired right up. I set timing. Let her idle for a while while I checked for any anonymous leaks. No leaks good to go. She had been running for about 10 minutes at this time. I gave her a little gas using the throttle body and she revved just fine. I gave her a little more gas and I heard the blow off valve (SSQV) So finally I decided to take her for a spin. I shut her off and cleaned up my tools. Got in and no boost. My boost gauge will read zero and that is as much as she will boost. Now I don't have a boost controller I have the HKS wastegate actuator set at 12 psi. I have been driving the car like this for a year with no problems. Before I take everything apart to check the turbo does anybody have any ideas or has anybody run into this before. Any help will be appreciated. Thanks

pressure test the system for leaks

[Mistaken]

Sounds like a boost leak.

[nice_try]

boost leak would cause car to hardly idle! and run absolutely horrible! what is it doing??

[theboz]

I found the problem. The turbo seized. The compressor doesn't spin at all. So in essence I am now running a RWD SR20DE......lol I am in the process of trying to find a new turbo.

HEY i will hook you up 150 shipped for my t25 i need it gone asap. i have good rep on here. just ask diderson and wc and the guys i have done business with. here are some pics.

ZERO SHAFT PLAY....... and low miles. i upgraded to a gt2871r .64 that is th only reason i took it off. it spools great though.

[nice_try]

oh well i have a question for you..i have an sr20det..i got a faze boost gauge hooked up and i got exhaust put on finally and drove around it sounded awesome when it spooled it was so loud suckin in air! but i plugged my exhaust hole where the egr plugged in and now i can't hear the turbo at all anymore?!! but it still readin boost..i'm confused on what happened.

[idahotuner]

did you have the egr just venting if so then the sound you heard was most likely blowing of air went you hit boost and when you closed it then that stopped. nothing to be worried about.

[nice_try]

but its ok that its quiet and i can't hear it? thats normal?oh and sorry for the thread jack..

[idahotuner]

Quiet is good usually, means everything is working smoothly, haha yeah my t25 was pretty quiet unless i rompped on it. what kind of intake pipe are you using? if it is the stock rubber one you wont hear spool as loud, if you ant to hear spool i recommend getting a piping pro intake pipe or some other intake aluminum pipe.

as far as thread jack i haven seen the op around yet. i even emailed him. so lets hope he comes back and wants my turbo

[nice_try]

i was just makin sure. but yea its stock rubber.. i'm gettin a greddy m spec with alum pipe soon..with hks or greddy bov. will it run too rich with an atmospheric dumping bov?

[idahotuner]

the M spec is an FMIC isa good intercooler but i doubt you will be able to find one for sale that isnt used, seeing as how they are discontinued.

I wanted one but settled for the LS greddy intercooler. it was like 30 bucks more. i hada turbo xs bov vented to the atmospher and it only had it back fire twice in the whoel time i was driving it, and both of those times was going up a steep hill.

i have yet to test out my new HKS SSQ bov and see if it back fires at all when i drive it.

there is alot of conterversy over this but it works for soem and notfor others. so do it and if you experience problems then recirculate it.

[nice_try]

gotcha! you've been alot of help! thanx much!

[idahotuner]

hey no problem man.

[inkslingers13]

atmospheric blow off valves will also cause some nice fire balls i like them

[idahotuner]

i never reved mine at night to see. or had some oen rev it for me i will check it out when i start driving. it will be kickA$$ if it does. liek at a stop light haha. start the car on fire behind me ..

they might get mad but they will be on fire haha

LMAO!!!!! thats great LOL!!!!! ive got 2 step launch control so its like my rear bumper lites on fire cuz it miss fires the car!! up to 10psi at a stop lol, talk about blowing the tires off my car!!!

[idahotuner]

ive got 2 step launch control so its like my rear bumper lites on fire cuz it miss fires the car!!

is that like an avc-r? becasue i am getting one of those it has scramble and gear based boost setting which i think is the same thing.......

WTF it starts your bumper on fire. i dont want that to happen haha. might have to makea heat sheild or soemthing fancy.

[inkslingers13]

nah, you dont know what 2 step is??? lol, its a secondary rev limiter that allows you to build boost at a stop, its part of my AEM stand alone lol. so your at a light, someone revs at you, and you 2 step the **** outa them lol!!! then there like.... wtf mate... look it up on you tube. its bad to the bone for launching at a drag track. ima set mine to 3800rpms. floor it and your car red lines at 3800rpms at a stop and you just watch the boost go up and up. its the same thing a a BEE*R box.

[nice_try]

wow thats badass where do you get it whats it called and how much??

[inkslingers13]

there a full stand alone ECU, so you replace your ecu with it, AEM EMS sells for the sr20det for around 1700$... but its the best mod for your car.

[idahotuner]

if i built my motor for mor then 450 hps i would go stand alone but enthalpy will work fine for now.

[inkslingers13]

get the bee*r box... its fun

[srdub-t]

you can actually have enthalpy program in a 2 step into your tune. Itl be hookd up with your clutch switch so when your clutch is in it will be limited to what ever rpm you told him to set it at.

[idahotuner]

awesome. i might have that done when i get a reflash. well i was jsut out messing aroudn with my car and i am pretty sure it is shoting flames out when i let of the gas haha. will be kick ***. at a stop light.

[inkslingers13]

yep, flames kick ***!
