It's always sucks to build a nice, clean motor then put it in a car to use it and let it get filthy... But then you step on the go pedal and all is forgotten.


I did get a new plate for the car... Since all Subaru's are Stage 2 and all:

The motor is pretty well ready to go back in. I just need to replace the shifter bushings while the transmission is more easily movable in order to get the shifter out.

Instead of making a new thread, ill ask you right here. What is the exact purpose of an uppipe? Havent learned this yet. :tdown:

Thanks for the pics! Very nice with the colors! :tup:

Better flow and in my case, to add an external wastegate.

So whats the difference between an uppipe external wastegate and a downpipe external wastegate?

A wastgate on the downpipe will do nothing. Wastegates bypass exhaust gasses AROUND the turbo.

An internal wastegate, such as what is found on the factory turbo, will bypass the exhaust gasses around the turbine, however, the exhaust housing still has to 'process' all that flow. An EWG bypasses the turbo completely leaving the exhaust (pre-turbo) less choked up.

Awesome! :ty:

Fired up on the first try! The pistons are quieter than I thought they'd be. I fired it up, topped off the coolant, then went out for about 10-15 miles giving it 10 PSI up to 5,500 - 6,000 RPM and lots of engine braking in between. Vacuum at idle is sitting at 22+ in/Hg.

Already on the second oil change too!

After a bath.

I do have a few temporary items I need to sort out from waiting on a couple more small parts, but I had ways of making everything work with what I have. Feels good to drive again. 1/4 throttle is faster than my S2000.

I am pretty amazed with this clutch so far (South Bend Stage 3 Street). I figured it would be stiff and shudder a lot like my buddies ACT XTSS, but this one isn't much stiffer than stock and doesn't shudder. I was worried about that and was planning on deleting the CDV prior to putting the motor in, but I never got around to it. I will still probably do it, but it really drives like normal.

I found my DAM dropping last night while rigorously exercising the car. It's not knocking, the knock sensory is picking up the noises from the forged pistons and labeling them as knock. Tonight after work, I will reduce the sensitivity and try again. My plan is to take it to the drag strip on Friday and see what it will do on my break-in tune. :)

To this after the DAM dropped to .1.

I got an itch this past Friday and decided to take the car to the drag strip after a full day on the road course with my S2000... I guess I needed some torque in my life. :)

I'm reminded why I don't drag race... I suck at it. Even as the car sat, I should have gotten it into the 7's in the 1/8th mile, but meh. I was and still am on my break-in tune, which consisted of me turning the boost down to 18 PSI (from 23) and using the AP to remove 3 degrees of timing, globally. I also found on my most recent map, I hadn't changed the throttle to keep it from closing as I neared redline. Coming from the DBC and soft clutch S2000, I had a difficult time banging gears and coming back onto the throttle in the STi, which resulted in no boost coming into the next gear.

With about 1,200 miles on the new motor as of yesterday, I changed over from Rotella T to Motul 300v (5w40). I've got several track and AutoX events lined up with my S2000, so I am hoping to be able to get some time to go through the car (boost leak test and such), and turn up the power and take it back.

Anyway... I brought my GoPro, but didn't think my times were worth setting it up. However, a buddy I ended up running against had a camera in his C5 Z06 and his friends also took video from the stands. It was a fairly warm and very humid night. This run is one of my worst times of the night, with my best being an 8.0 @ 88mph.
