Anyone looking to buy a stillen gen3?

jwick 05-29-2017 09:49 AM

Post it in the sale thread. Somebody will buy it.

hc_416 07-21-2017 03:42 PM

so my car started to overheat when I was warming it up today; I was talking with my friend across the street and notice anti-freeze coming out. I turn her off ASAP. After I let it cool down I took her for a quick drive and noticed she was driving fine, but at lights she would get really hot so..... I went under the hood and noticed that my fans are working. Can anyone give me a direction on what I should look for first? I put on the ac to try to start the fans, but it comes out with hot air and the fans don't kick on. I want to check the fuses'/ relay next does anyone know which one they are?

Jayhovah 07-21-2017 03:48 PM

In before SouthArk directs you to FSM in his sig.

Constructively, I have nothing to offer. Hope you get it figured out! Ill bet its something stupid like a fuse.

hc_416 07-21-2017 03:57 PM

eh i hope not, just looking for advice. Both fans went out at the same time so it might be something in common with them. Maybe a fuse or a bad fan control module. Is there a way to check the module and the fuse?

2008 g37’s six speed coupe
Problem car is overheating due to fans not coming on.
Hey guys I have a question to the mechanic’s out there or anyone that could help!
1. The first questions is can I replace the pmw relay underneath the battier cover? I cracked it while trying to pull it out.
2. The second and bigger problem is my fans are not coming on at all, hence why I was looking for the fan relay to see if it is bad. Is the pwm relay that I cracked for the vvel motor or the fan relay? There is two relay’s and it is on the passenger side. I was/still am looking for the relay for the fan. Any help would be appreciated.

well it was a easy fix, my control module went out. I order one from z1 for 54 bucks and just swapped it out. Now its running as it should!!\

I did some research and watched this from YouTube. https://www.youtube.com/watch?v=HO7IQuRbDIU

Once I saw the fans were working it was pretty easy to fix. I guess this was a pretty common problem. It went after we had a week heat wave over here in CT.

A couple vids of the start to the season! I only hit about ten pounds, I am still getting used the car she can hit about 16-18 pounds.

hc_416 11-02-2018 07:34 PM

well an update... My turbo seems to have broke i have oil out of the tail pipe and oil leaking by the turbo... it now makes no boost. I'm thinking damage to one of the wheels inside. Maybe ill get that ATS - V!

solidus 11-02-2018 11:57 PM

If you're still running an exapump I have a damned near new 6466 1.32ar to sell for cheap.

hc_416 11-03-2018 10:11 AM

thanks for the offer, but i'm just looking to rebuild the turbo. I want to take it all apart and make sure its not just a blow seal first. If it is not, ill see if Sasha can get me a new cartridge.

Are you sure the exa pump is working?

If the scavenge pump failed that would explain oil getting down the exhaust but he should still be able to build boost ...now I would assume if the pump failed it could have blown the seals out ...prolly needs new turbo seals and check the scavenge pump

cool thanks for the advice, I will check that out!

hc_416 11-03-2018 03:39 PM

Hey does anyone have a link to the install kit? I want to make sure if I take it apart it will go back together.

solidus 11-03-2018 03:46 PM

I just went through this with the exapump. Check the exhaust , and also the intercooler. My wiring for the exapump got nicked during motor install. Had oil everywhere. Ended up having to soak the muffler in a bucket of gas to get rid of the smoke. Oh, and taking the turbo off is simple. It's just on the flange for the manifold, no need to take off anything other than oil lines and the lower charge pipe.

Jinxx 11-03-2018 04:23 PM

So with the issues you guys are having with the oil fed and scavenge pump why not switch to the comp oil less turbo

I took off the intake pipe at the main and didn't see any oil, I'm hoping it just shot int he exhaust. If so ill just get a new one, i need to put a cat in anyway to pass emissions. Gonna start next week, to much work and real life stuff. what do you guys think about the ats v ?

I would have right vefore I did the 6870 but I didn't even think of it till Sasha said something. Scavenge pump isn't really so much a problem as it is a temperamental bastard. First failure I had was from pieces in the system with my engine pop. Replacing it was easy. This last time a wire got snagged during the built block process.

There have been more issues with the Comp turbo than with the exa pump.

None of that is the pumps problem.

Which is basically what I said. The thing with the pump is that it's one more thing to go wrong , and that wrong could come from any number of things unrelated to the pump itself. I'm not making stuff up I've lived it. With that said if it were that much of a big deal I wouldn't still be running the exapump. Going with a Procomp wasn't on my radar until Sasha himself mentioned it to me. It simply prompted the thought of the simplicity of the setup. But I will say that if I get a wild hair the exapump is a gonner.

A lot of them have been install related. I would say that the COMP turbos are performing better than the standard Precision JB turbos the kit came with.

The other REALLY BAD part about the Precision turbos, is that the manufacturer blamed any/all issues on "oil contamination" which I always thought was complete BS. COMP on the other hand repaired issues at no cost, even when it was an install error.

I have a Precision 6266 with a brand new scavenge pump in stock, as well as a COMP 6767. The COMP is what I'm putting in my car with the build this winter.

Jinxx 11-04-2018 06:56 PM

I haven’t had any issues with my comp turbo ... I’m at about 22k miles on it .. only thing I have noticed is you can hear the ball bearings at low speed and idle very faintly ... doesnt seem to affect performance or anything .. you can hear the turbo spin for about 20 secs after the car is turned off. And most research I can find on triple ball bearings people tend to say they that’s about normal. Not to imply that it’s better than an oil fed turbo but just the simplicity of not needing oil lines and scavenge pump to deal with is awesome

Hey Sasha, what do you think the problem could be? Also how much would it be to get a cartridge if i need one?

Well, I would start by pulling the turbo, or at least the down pipe to see if the rotating assembly spins freely. If all is good there, check the oiling system, and ensure the pumps pulling vacuum at the turbo oil discharge side.

Yeah, that is normal. My Precision ball bearing did the same thing. Once the COMP turbo is broken in, it spools fast/hard. Mechanical efficiency is extremely high with these units.

hc_416 11-09-2018 03:54 PM

So I took off the down pipe... Filled with oil. I look at the lower input on the inter-cooler and it has oil dripping from each joint. The turbo looks full of oil but it does spin, no shaft play. So what do you guys think should be the next step? Here are some pics for reference.

Same exact thing that I just went through. Turn on accesory power and see if the exapump is running. Mine had the wires jacked up during install or uninstall of the engine. Also afterwards oil was in the exhaust to the point that I had to dunk it in gas because trying to burn it out by driving was like a smoke generator on a tank.

hc_416 11-17-2018 05:52 PM

Well i did not get anything out of the pump so I pulled it. I got the relay too. Here are some pictures. Looks like the inter-cooler stopped the oil from going in the engine. Next week I am going to drop the turbo and drop the rest of the exhaust. I can then find someone to clean it out.

1. Is cleaning the inter-cooler a good idea, and how should it be done?

2. Were can I get a new oil pump, or should I have mine rebuilt?

solidus 11-17-2018 07:24 PM

If the exa is bad get a new one but first try to runbit on 12v. If it's still busted replace it. Sasha can probably source you one or do like I did and amazon prime that bastard. You can easily clean the intercooler and exhaust by yourself. You need a couple gallons of gas and a bucket. Degreaser didn't work worth a crap. I said it's easy but it's a pain in the ***. Or.....you can just smokebomb till it burns off. Been there, good luck.

hc_416 11-25-2018 03:46 PM

I am making good progress. I need to just get one bolt off the turbo.... but it is the hardest one. Does anyone have advice on how to get the top right one; when looking from the passenger side? I have some pictures of my progress and the last bolt i'm working on. I'm just doing it a few hours on a weekend day. I figured it would make it easier and not as stressful. Also does anyone have a link to the pdf download for the install guide? I will need to to put it back together. I'm bagging and tagging but will need the guide.

I'll PM you the install manual link.


As for the top bolt, pull the oil reservoir off the turbo, and use a wrench from the transmission side.

hc_416 12-22-2018 11:57 AM

Hey guys,

Was back at it again. After i got the pump off i took the bottom plate off to see what happened. I see no shear pin? in one of the gears; and if im correct that is what attach's the gears to the pump!! is there anyway to just get the pump rebuilt? it seems if you replace the shear pin it should work. Any ideas or info?

solidus 12-22-2018 03:31 PM

Same thing I saw I just bought a new pump after I saw they won't warranty or replace if you open it up.
