Default Whole bunch of problems

My car has been running very poorly. Trying to self diagnose it and getting it healthy is a slow and frustrating process. It's a 2000 rs2.5 with an ej207 swap with matching ecu, mishimoto 02 wrx rad, AEM short ram, turbo xs BOV, invidia downpipe, cobb cbe, JDM 4 pots.

My current issues are:

1. Car will get hot when sitting still- Raising rpms to 2-3k doesn't noticeably drop heat (water pump). Cruising will cool it down.

2. Loud and obnoxious whine from engine bay, appears to be an idler or something in that area. I believe if a tensioner is bad or something belt driven. Might be causing the waterpump to not operate correctly.

3. High pitch squeeling downshifting into 2nd, it's a spinning metal on metal type of sound. It's very loud and feels a little violent.

4. "Total Ignition Timing" numbers from rom raider are completely erratic just at idle.

5. Exhaust leak, due to invidia downpipe having a flat gasket flange and cobb middpipe having a donut gasket flange ( Trading for n1 or turbo xs soon)

6. No CEL but there's a lingering code regarding Camshaft positioning sensor code P0390. ( Sensor passes visual inspection, not dirty or damaged at all)

7. Car doesn't roll up/down hill like it should. Going to throw new pads/rotors front and rear (they need it anyways) hoping that's the cause.

8. Pretty rough idle, I believe (or hope) it will fix itself after I tackle the rest of the list.

9. Chirping throw out bearing/something clutch related. When disengaged it'll make a constant chirping, when engaging/disegnaging there's a point you get a constant squeak out of it every shift or at idle.

10. Complete drop of boost if WOT accelerating 4th/5th gear sometimes. Feels like all boost drops and you will continue to accelerate NA

11. Front passenger suspension felt weird, found the boot torn and grease everywhere.

My plan of action is to tackle the worst of the problems first.
- Check belt,pulleys, tensioners, timing and address those as they come up. Going to have a gates kit ready as the motor has about 55k on it. Some say it's early but I don't know how it was treated before me and I'm just staying safe. Also have read that cam seals should be done now also, have to read more into what the process is for that.
- If overheating problem isn't fixed by waterpump/belt I don't know what else could be wrong. Less than 1k on the radiator, fluids and t stat.
- If timing issue with romraider still exists will get a replacement jdm cam sensor and check for further damage.
- Compression, boost leak and vacuum leak test.
-Replace front axles/repair boots undecided how to approach this still. If possible I would like sti axles, some say it'll fit no issues, others oppose this.
-Pads and rotors for rolling/dragging issue.
-6 speed swap for noisy clutch and 2nd gear issue.
-Get a correct fitting exhaust for leak.


If anyone has suggestions to my procedure I'll gladly take anything I can get. Ditching the car in a lake isn't an option. Will shortly get videos up of every sound I can recreate.

Burp your system. Make sure tstat is OEM subaru tstat. Hydrocarbon test to rule out head gaskets.

2. Loud and obnoxious whine from engine bay, appears to be an idler or something in that area. I believe if a tensioner is bad or something belt driven. Might be causing the waterpump to not operate correctly.
Inspect the pulleys/idlers/tensioner & replace with Gates timing kit

3. High pitch squeeling downshifting into 2nd, it's a spinning metal on metal type of sound. It's very loud and feels a little violent.
Post a video of sound. Clutch/trans/throwout bearing?

4. "Total Ignition Timing" numbers from rom raider are completely erratic just at idle.
Fix your cam position sensor issue.


5. Exhaust leak, due to invidia downpipe having a flat gasket flange and cobb middpipe having a donut gasket flange ( Trading for n1 or turbo xs soon)
Fix this, lol

6. No CEL but there's a lingering code regarding Camshaft positioning sensor code P0390. ( Sensor passes visual inspection, not dirty or damaged at all)
Are the wires loose? Visual inspecion? Did you just look at it or actually inspect it?

7. Car doesn't roll up/down hill like it should. Going to throw new pads/rotors front and rear (they need it anyways) hoping that's the cause.
WTF? My car doesn't roll up hills? What does this even mean?

8. Pretty rough idle, I believe (or hope) it will fix itself after I tackle the rest of the list.
Clean IACV, boost leak test, check for damaged vacuum lines, fix camshaft problem.

9. Chirping throw out bearing/something clutch related. When disengaged it'll make a constant chirping, when engaging/disegnaging there's a point you get a constant squeak out of it every shift or at idle.
Replace clutch, lol

10. Complete drop of boost if WOT accelerating 4th/5th gear sometimes. Feels like all boost drops and you will continue to accelerate NA
Boost leak test!!!!!!!! Failing bcs/vacuum lines

11. Front passenger suspension felt weird, found the boot torn and grease everywhere.
Replace struts lol

I think I have a JDM cam sensor from a JDM EJ205 if you want it. Send me a pm and I'll try and find it.

Good luck!

I'd really appreciate that, I'll PM you and we can work something out. The up/downhill statement meant at an incline I won't roll back, at a decline I won't roll forward. IACV was gross, cleaned it got a new gakset. When I said "visually inspected" I took it out and made sure there was no oil/debris. Wires aren't something I necessarily looked at but, nothing seemed out of the ordinary. Some where I read there's an actual test with a magnet and multimeter going to find the correct procedure for this.
