Spoolin06XT

Looking for rear upper control arms if you have them?? Shipped?

Ok, will get a set of NGK's, the Denso was the only one available at the parts store I was at the time. Yes intake and cabin filters were the first 2 things I did when I bought it, so its about 5 months old. Thanks for that video too, it made the job easier though the engine was hot

So update on my testing today. Checked compression with the oscilloscope and found a minute dip in revolutions. So it took it for a road test while he read the parameters on his Snap On scan tool. Nothing abnormal, fuel trims were good. Bought some plugs and came back to the garage. Performed a clear flood mode and checked compression on cal #4, I got 149psi. Performed a leak down and they were within 3-4 psi of each other. With the car being so hot and being outside in the 95 degree weather I only changed #4 plug. It looked like the original plug and the car idled and drove a lot better. I think I will change the harness, coils and plugs and drive it again. I was able to use a denso but should I switch it to a NGK? I had some slight cylinder roughness in #4. I will post up Feedback Knock -4.00/0.00 Fine Knock Learn -5.02/0.64 Roughness Cyl #4 0/2 DAM 0.875/0.875 So far the car drives with no misses or hesitation. I drove it for over 2 hours and no issues. Could this all have been the result of a bad spark plug/lack of tune up? I was planning of doing a full maintenance and only had the timing belt/water pump done and tune up was next.

It seems to be happening just around 1500-2k and as I build up speed if feels like the car goes faster in increments if that make sense. As I accelerate the car seems like it is jerking(timing being pulled) trying to build speed, the turbo is however spooling strong as I can hear it. I will check using the AP.

Ok, I will go out for a drive tonight and monitor these parameters and see what I get. I need to get some plugs to replace while I am in there.

Will you have more parts for sale?

With the AP I can configure 6 parameters. My boost vac is still at 9/10 at idle which I know it should be around -20inhg. I will drive using boost,AFR,DAM,RPM, roughness #4 when I drive to my buddy's garage. I took it on a good 25 mile road test this morning and here's what I got. All of this at idle Boost -9.46psi Coolant 205F Knock Count 27 count DAM 0.750 Roughness #4 0/2

Yea, my buddy is pretty good with diagnosing and I am mediocre at best. So between us hopefully we figure things out.

@samuel082799 that would be great if you can post a link. I asked for a leakdown/compression test when I got the T-Belt done but the shop was too busy to do it. I wanted to know what was going on with Cyl #4. It make sense what the DAM/IAM does and the way you explained. I definitely believe timing IS being pulled. When I briefly drove it tonight I can hear the turbo spool but the car wasn't moving any faster. The more I accelerated, the turbo spooled, the car hesitated then I would feel it pick up speed. I will go over to my buddy's and do some work on it this weekend. He has an oscillioscope and can do a relative compression test. If I find a low cylinder then I can do the static compression/leak down tests. I will also pull the IC and see if I find any oil in there as well. Thanks for stirring up the juices, that video link would be helpful. I think I will get some new plugs and swap the left side bank coils to see if that knock follows to the next cylinder.

Took the car out on a short drive, thought I would be able to drive longer but the skies went completely black from the thunderstorm coming. Knock sum >> 0/28 count DAM>> 0.000(driving/idle) Coolant temp>> 200F (sitting at light) Roughness Cyl 4 >> 0/2 Boost(vac) @ idle>> -9.4psi Does this give an indication of where to look other than the infamous #4 cylinder?

Ok will monitor the DAM. I recently had a timing belt service but didn't replace the OCVS. I think with the mileage I will replace them just for peace of mind. 8lbs is low as when I did the Cobb tune I believe I was somewhere around 12ish pounds. This is the generic Cobb Tune. I will search for the vac source thread and the fuel hose length and see what I come up with. I will check for leaks as well. What is a good method of finding a vac leak. Doing it from the intake hose with a gauge or smoke tester? Thanks for your input everyone, I appreciate your help.

I will check the AP for those parameters and give it a try. This hesitation(which could be called a stumble) happens when I accelerate and at idle. I did notice it at idle when I got the car but it never effected anything else. So I wonder if I may have 2 separate issues going on here. The hesitation while driving would only happen when I accelerate then it would go away. As another member stated and what it felt like was timing being pulled(maybe knock) and then it releases. The last time I drove it it was not as abrupt but the car did not feel a peppy as before. And I am only getting 8psi at full throttle in 4th. Is there an on car test for the OCVS, such as resistance? Or can I use the AP and it give me an indication to look at the OCVS? I will attack this this weekend to see what i can come up with. Still have the same gas from the last time, once I reach quarter tank I will put fresh gas and see if that helps as someone suggested.

The parameters of the AP does not go that far in depth. I did drive the car yesterday and it does not hold back as bad as the other day but it still hold back. I’m at half tank of fuel so I will wait till quarter tank and run some fresh gas and an additive to see if it helps. Turbo spools good, no noises parked or driving. I do have knock summary of 27 after about 20 mins of driving. I do have a #4 cylinder giving me knock feedback. Doesn’t seem turbo related however. Will take a look at #4 coil/plug this weekend.

Next time I drive it I will connect the AP. I usually don't drive with it. I am not getting any noises and it spools great, matter of fact most of my driving is with the radio off just to listen to the turbo spool. Just for peace of mind I previously acquired a VF52 and just waiting for JMP to give me the go ahead to ship it to him for a rebuild. This is my first Subaru, not new to turbo cars, but I am still learning this platform.

Hey guys, I have a 06 OBXT 5MT with 137k on it. I picked it up with 134k, and slowly doing all maintenance to it. First thing I did was the T-belt/H2o pump and associated seals/hoses along with the P/S pump all OEM. I had a fluctuating temp gauge and ended up doing the upper hose and both coolant caps. Drove the car to work yesterday and on the way home everything seemed fine. I still think the temp gauge moves a little towards hot but barely. So on the way home I noticed the car lacked power. When I changed gears and started to accelerate the car would kind of hesitate and feel like it has a restriction then all of a sudden it takes off and I hear the turbo spool. I didn't want to cause any further damage so I drove home and parked it. Do you guys think this is a failing turbo? No check engine light but, I am going to check with my AP if there are any. Oh btw I have a stage 1 tune on it. Any ideas or suggestions to what I should check? TIA for any help......

Ok, keep me in mind for that set por favor.

Cyber R or Cleared extended CF since someone sold my cleared CF

Are the rear upper control arms still available?

@kingsebastian.....awesome news.....hope as well this continues to work good for you and solves your issue.

That's great news! Hope it remains that way for you. I too ordered a set of hoses and caps. I will be trying the same in a few days with fingers crossed.

@m sprank Looks like a good kit and it seems like they resurrected the price too:lol:

@RI spec b PM'd.

@EB'sOBXT that's awesome. You just confirmed it for me and I will opt to go TMIC instead of FMIC since I am only looking for 300awhp. Sounds like you have a good cast of supporting mods as well. Have you considered upgrading your fuel pump as well?

@EB'sOXT did you ever get your TMIC?
