Fyi those settings were from the track

If you hit any of those on the street I would be amazed

Temps are normally like 190-205 for Oil and 180-200 for coolant for me on the street

ECT shouldnt be over 250, 180 to 230 preferred.
OILT, with my setup and oil choice, should be no higher than 350. 200 to 250 preferred.
Set both of those warnings to 210 and will call it good.
OILP shouldnt be less than 5.
Alarms set!
What are you concerned about? Daily driving or track days?

Thanks for the assistance.

Yeah, daily driving profile and autox profile.

We live in Seattle area and it's been hot lately. Got really nervous when I mistakenly got caught in traffic.

Keep an eye on your oil pressure, especially on super hot days. If it drops to around 25psi or lower at idle and below 65psi-ish at speed. Take it super easy until you get home and let the engine cool off with the hood open. You do this by turning the ignition key to the on position after shut off (but don't restart the engine), the fans should turn back on. Let the fans run until it turns off, remove the key, and close the hood.

You mean hot for Seattle... it's still not much.

Default What to do

So I have an EJ207 V7 dropped into my 04 WRX with the JDM 6 speed and R180 rear differential, 4 pot 2 pots for brakes with the sti axles and knuckles on the rear.

Was on the throttle good heading up the Route 2 WB hill out here and bam lost power started blowing white smoke out the rear. Towed it over to the mechanic and will do compression test tomorrow but its burning oil and he thinks I may not be getting compression on one or two cylinders the way it sounds when cranking.

Tryinging to weigh my options right now. Continue trouble shooting the block or just weigh options of dropping in another V7 or V9? Thoughts suggestions would be appreciated.

How much boost were you hitting and what turbo? I'd figure out why you blew it before you drop another engine in or you'll be right back where you started.

The stock turbo that came with the V7. The VF34. Boost was setup for peak of 21psi, with a dump at 25 if it ever over boosted.

Wicked Performance up in NH did the swap and tune when it went in originally back in 2014

Default Mechanic update

So the turbo blew on my v7. Oil all in the ic etc. Compression test shows 0 psi in cylinder 3. 145 to 150 on all others. So looks like I am into a rebuild. Had already gotten a dom 1.5 with fuel lines and rails a 3 inch inlet and new upipe as well as ID 1000s for a planned upgrade. Might as well salvage all this planned effort. Any advice appreicated on those that had rebuilt their v7.

Does anyone know if the killer B oil pan would clear the twin scroll manifold?

It does. I found more info here and there and got some from Killer B as well. I had the oil pan installed last month on my V9. You may have to trim some heat shielding.

Thank you for replying so quickly! I'm currently using a 2.5l pan and figured it would work. I'm not too worried about heat shielding. I was thinking about removing and changing it to BMW/Porsche waffle type anyway.

EJ207 already has what they call a 2.5L pan making it more confusing when doing the research.

2.5 pan and twin scroll should almost be the same pan. Now the killer b is designed on that same idea.

Its the same part number for the Twinscroll pan and the EJ257 pan , But that being said I would not put any Killer B part anywhere near my car.

From my experience the answer is...kinda. I had to take my dremel and cut out a bit of flange out of the factory header heatshield to clear the version 1 style pan.

Internet Myth, they are the same.

Jeff Sponaugle once posted the JDM Subaru part numbers that proved that the cams were the same. Ill see if I can find it.

This isnt Jeffs post, but this has corresponding information. https://forums.nasioc.com/forums/sho...6#post10671156
