Answered you over in the "build" thread.

Of course not, we always build in stages expecting these types of failures. It's the only way to learn how to build around and solve them!

Also I'd LOVE more information on the rebuild after the fire!!! Extremely interested in your decisions you've made (been following your subie builds for a loooong time), as they've influenced my buying and setup decisions before.

I posted pics in the build thread but more details over on Facebook. I have a plan to help the steering with a cooler I made but we have yet to test it. We are just so busy with our client engines it was a real struggle to get the FRS back from the dead.

I basically took only a few warm up laps at Road Atlanta to heat the tires and as soon as I turned it up it didn't make it a full lap. It was the same for our STi once we pushed pasted a certain g load andwent dry sump to solve it and make it reliable for extended high g tracks.

We'll get the engine together again quickly and on the dyno for more controlled testing. If rpm oil pressure to 9k rpm is good I'll be very happy. Then I'll just make a 2 stage scavenge dry sump.

Thanks,
Phil Grabow

ya id bet. good for me im on so4 pole positions but spending so long near redlinw makes me wonder about 0w-20

Factory redline and N.A. on "street" class tires should not be a problem. If your not starving the fuel pickup at Lightening you're likely just fine on the oil pickup.

Super high oil temps will effect the oil pressure with 0w20 from what others have recorded but pressure demands are a lot lower for 180 whp than what turbo guys will see. Last season 10w40 worked well for me up to 350 whp and 7500 rpm.

I can't believe I am seeing this, but is that a functional Rocket Bunny kit? I think I am in love.

Ha ha I know, right? She's "hella" flush when I'm pulling through a turn a 120mph

[Element Tuning]

It was a hot mess!





This is what was in the pan of the stock engine. Serious carnage when I blows at 120 mph!

Glad to see you back Phil!

I'll be getting a Hydra from you as soon as I sell my WRX one.

If you need a new engine, I have a factory fresh complete engine.

ya im planning to get a oil psi gauge and maybe a oem forester oil cooler. on a ~70 degree day it was tracking at 230deg oil temp and coolant at 200 so i think a little coolant ring around the filter should cut it

@D K I might be interested in a spare motor.
@Grip Ronin if you water temp is stable those water coolers can work decently well. That's may plan also as I run a massive radiator. Also typically with a dry sump tank you have a ton more oil to help with heat. 230f is totally good for oil temp!

My rod bearings coming from Japan due to a national backorder? Must be a lot more busted bottom ends than we know about.

Managed to get mine from Subaru UK in a day.

Interested in your plans for dry sump.

I jumped ship to Toyota and I was able to source some faster from Ohio. I'm keeping the Subaru ones on backorder though

I want to do the dry sump with a CNC pan so it's going to take little time to get that all sorted.
