Any update on this?

I just got word back from the machine shop that the block I dropped off if perfectly good to use 99.5mm pistons with a very light hone. I will be going with CP 9.0:1 compression pistons. My crank and rods are good to be re-used. The machine shop will get the correct ACL bearings. I am going with Supertech standard size intake valves and standard size inconel exhaust valves. The heads are getting ported as well. I will be keeping my Tomei 252/252 cams. I am also swapping to a N/A aluminum intake manifold, then using AVO's N/A turbo kit piping from my FMIC to the intake manifold. So no custom piping has to be made. Everything should be easy to bolt together. After driving a 700whp STI with an Exedy triple disk unsprung clutch last night, I really want to put one in my car. That is by FAR the BEST feeling clutch I've ever driven. Feels like stock, or even slightly less pedal pressure. But since my twin disc is still perfectly good, I'll stick with that for now.

Thanks, but I already have one. I need to figure out my windage tray situation though

Awesome! Let me know if/when you want me to send out my broken one.

And my KillerB oil baffle tray broke. This is how it came off the block when I removed the oil pan. http://www.strizzyphoto.com/photos/i-8T7qSp9/0/L/i-8T7qSp9-L.jpg

So.... Where to start? I got about 10k miles into the motor. The last 3k miles were on E85. Was hitting a long straight (track) and around 130-140mph (high engine load), something hiccuped and lost power and boost. With all the symptoms, it looked to be a head gasket failure. After the engine was torn apart, things became more apparent. I had some sort of massive detonation in cylinder 2 that blew a hole through the side of the piston and blew out the head gasket. http://www.strizzyphoto.com/photos/i-6v3zSqT/0/L/i-6v3zSqT-L.jpg http://www.strizzyphoto.com/photos/i-9hc7hjg/1/L/i-9hc7hjg-L.jpg http://www.strizzyphoto.com/photos/i-XGVsJZn/0/L/i-XGVsJZn-L.jpg The tip of the spark plug melted http://www.strizzyphoto.com/photos/i-w29rFnQ/0/L/i-w29rFnQ-L.jpg And to top it off, one of my cams broke again. Exactly like the last one, but this one is a different cam. My car was tuned for 20psi, since my fueling at the moment couldn't handle the higher flow required for E85 at higher boost. I've got a couple stock EJ25 blocks on hand, and one of them looks good enough to do a light hone for a set of 99.5mm drop in pistons. I will also be going with new valves, springs, and retainers. I am looking at my options for larger cams. And I will probably do a mild port on my heads. My crank and rods are still perfect, so those will be reused. I just need to decide what compression ratio pistons I want to use with my D25 heads. I will exclusively be running E85.

How's your clutch?

Did it look like this? http://www.strizzyphoto.com/Other/Subaru/i-87X7wv6/0/L/IMG586234tonemapped-L.jpg If so, that's mine

Was it a 2008 in QSM?

Yes, stock location. But is WRX style, so it would need either Process West TMIC or FMIC. I welded the internal waste gate flapper and clocked the turbo for a direct fitment with my AVO FMIC, without the need for extra pipes. Perfect fit.

Probably should update my "clutch" issue. Clutch didn't go out. I snapped a rear axle. No one makes a stronger replacement for the specB's, so OEM axle went back in. There will be a stronger option coming soon though. My clutch is still acting a little funny since the track, so I have replacement discs in hand ready to swap when the time comes. Car is now at the body shop getting the driver side rear door fixed from my neighbor sliding into me during the winter.

OEM stopped holding stage 2 after 10k miles. Exedy HD stopped holding my 20G after about 1500 miles. Stage 3 Comp Clutch couldn't hold during my first logging pull. Exedy sprung twin disc stopped holding after 6k miles and 30ish launches. 4 engines if I include the original.

I was too, but my clutch was acting up (slipping quite a bit, then semi welded itself to the flywheel, as I couldn't get into gear unless the car was off. (Which also makes for a fun time starting the car )). Then yesterday the clutch finally gave out mid-shift 1st-2nd. I thought my trans dropped from the car. I'm either going to rebuild this one, or try an ACT 6 puck.

What are your AFRs at idle?

If that's the case, I would just need to find someone that can tune it. My tuner won't touch it. Not familiar with it and claims he's only heard horror stories with it.

Doesn't UTEC only take over open loop fueling? If that's the case, then I'd assume he got those injectors to idle fine with 93 on the stock ECU.

Stock ECU? I think you said it was, but I don't quite remember, and I don't feel like searching for the answer.

So just another OEM unit would be needed? Like this one? http://compare.ebay.com/like/280855097470?var=lv&ltyp=AllFixedPriceItemTypes&var=sbar&_lwgsi=y&cbt=y Along with a second Aeromotive 340 with dual in-tank pump setup like something from Full Blown? Was your friend able to run pump93 when needed? My friend with his stupid big build is running strictly E85 with ID2000s. But he has an Aeromotive 340 feeding a surge tank with two Bosch 044's. Our tuner was saying something about the 32-bit ECU can't lower the injector pulse width enough to get the car to idle on pump93. But because E85 requires ~30% more fuel, the injectors can idle the car just fine. I need to be able to run 93 when E isn't available, as I drive a lot.

ID1600s are discontinued. I have a friend with 1400s from Five-O Motorsports with a flowchart that shows them flowing like 1600s. Would you be able to point me in the direction of the fuel pump controller you mentioned? Switching to E is something I would like to do within the next month.

Here's a quick acceleration test. No, this was not done on an open road. I have access to a private airstrip. Yes, it's as fun as you think it would be. No, it's not like the Top Gear test course.

Stupidly long parts list that I'll have to get from him tomorrow. Here is his Dyno sheet from yesterday though. his second pull he blew the coolant reservoir and had to end the run early. We thought he separated his heads again. He's pushing 35psi. http://i2.photobucket.com/albums/y36/ddejaege/dyno05-06-12.jpg

A friend of mine built his motor to be very rev happy. He can rev to 9500 is desired, but around 8750, his oil pressure starts to drop. He destroked his 2.5 block with a 2.0 crank, sleeved the block, and bored it to bring his displacement back up to 2.5L. He made 610whp and 598wtq on the dyno yesterday. He's also running a massive HTA86. But he literally has a 5k RPM power band and can break the tires loose in 4th gear. That car is just plain scary.

I have some future plans for slighty bigger cams and some minor head work. Not sure when I'll get around to that though, as I am extremely happy with where I am now. I also feel that my 7k redline is perfect for this setup. I'm still debating on the switch to E85. I might just get a FPR and up the pressure and see where that can get me. I would like a bit more torque.
