I Donated Too sigmafour Posted January 23, 2017 I Donated Too Share Posted January 23, 2017 Build number one which can be seen here ended in complete carnage and can be seen here There wasn't a lot left but this is the story of what was and what became of it all; And now because I do not want to do this again I have built a (fairly) reliable daily driver 500hp monster. Only I don't drive it every day because it won't always let me and it's just not that much fun in traffic. I'll get to that. http://www.sigmafour.net/lgt/build2/635894866431341.jpg Even the case halves were shot. Almost everything was junk so it was time to start again. Here's what I ended up with. A 1200hp block with a 500hp Turbo so the engine is a honey badger.

Meanwhile. The car too sat motionless, without an engine. http://www.sigmafour.net/lgt/build2/IMG_4194.jpg Where it would sit for just over a year until I could come and get it and finally get it back on the road. Even then, that wasn't going to be the end of the story. Link to comment Share on other sites More sharing options...
I Donated Too sigmafour Posted January 23, 2017 Author I Donated Too Share Posted January 23, 2017 My existing block was too damaged to use so a salvageable block was located by the machine shop for $500 and then these parts were sent along. http://www.sigmafour.net/lgt/build2/IMG_4353.jpg http://www.sigmafour.net/lgt/build2/IMG_4354.jpg http://www.sigmafour.net/lgt/build2/IMG_4355.jpg http://www.sigmafour.net/lgt/build2/IMG_4356.jpg http://www.sigmafour.net/lgt/build2/IMG_4357.jpg http://www.sigmafour.net/lgt/build2/IMG_4358.jpg http://www.sigmafour.net/lgt/build2/IMG_4360.jpg And then what was salvageable was sent to a local machine shop for cleaning. http://www.sigmafour.net/lgt/build2/IMG_4535.jpg But sadly... after cleaning this part was also found to be destroyed. http://www.sigmafour.net/lgt/build2/IMG_4537.jpg It is surprising to see just how much force the piece of the block came out, with enough to imprint it's shape in the water crossover pipe and cracked it. Could have been fixed? Didn't want to... Link to comment Share on other sites More sharing options...

I Donated Too sigmafour Posted January 23, 2017 Author I Donated Too Share Posted January 23, 2017 Looks a lot better than my last short block...

Rester5350 Posted January 25, 2017 Share Posted January 25, 2017 What materials are you using for the o-ring a and hg? In the pic it looks like the o-rings are ss? My rings are copper with mls hgs. I was under the impression you would need receiver grooves in the heads with ss/mls, and ss/copper hg were prone to seep. Link to comment Share on other sites More sharing options...
I Donated Too sigmafour Posted January 25, 2017 Author I Donated Too Share Posted January 25, 2017 o-rings are SS and the HG must be an MLS but I must admit I am not sure exactly what goes into a Cometic brand HG. I do remember we needed an 030 because of that piston with 0 deck and it was advised we use the Cometic brand by the machine shop (who build a LOT of these engines) so that's what we did. At this time the engine has well over 20K miles on it so far with no issues (with the engine). So far so good. This was the same machine shop who built the Subacabra engine and there are a lot of similarities with that build and mine. When my first engine blew up the Subacabra was the current talk of the forums and friends were all oooohing and ahhhing over youtube videos of that 700hp monster - It was an EFI built car but EFI don't have a machine shop, I soon found out where it really came from. The AEBS T sleeves were key for me in finding who machines those in this area. Rottler machines, big money and the guy who does it, very skilled and knows his stuff. The Subacabra has since vanished... I don't know where it is today. It was sold I guess but I wonder how many miles it has on it? The machine shop said to the engine can run 1000hp for about 15K miles but put just 500hp into it and the engine would see 100,000 miles. So that's what I did.

Rester5350 Posted January 25, 2017 Share Posted January 25, 2017 I always wondered where that car went. I am more than happy with my benson sb, even though I'm barely pushing it at 25 psi with my little 76hta lol. It's my dd right now has had 9k miles put on it since June.

I Donated Too sigmafour Posted January 25, 2017 Author I Donated Too Share Posted January 25, 2017 Yes on the valves. I gave the part numbers in the list up there and I have wondered if I should have done +1 but I still ended up where I wanted and the car is VERY quick. I didn't need them...

I Donated Too sigmafour Posted January 31, 2017 Author I Donated Too Share Posted January 31, 2017 I lost track of time but months and months passed. The block had sat in the garage and the heads were sat at Motive. In the back of the dead car the intercooler had been stored but now it was time to start getting things done. http://www.sigmafour.net/lgt/b2/IMG_8103.jpg This came out and went to a machine shop for some bungs to be welded in. http://www.sigmafour.net/lgt/b2/IMG_8230.jpg One on the front for methanol injection and the first one in the exit elbow was plugged and welded over. One more added in the top for the IAT sensor. The block was dusted off and taken down to Motive for assembly in the shop. Seeing these parts put together definitely made me feel better but this was still a very slow process the plan was only bring the car down once the engine was ready to go in. It was still going to be a couple more months until that happened. http://www.sigmafour.net/lgt/b2/IMG_7513.jpg http://www.sigmafour.net/lgt/b2/IMG_7600.jpg http://www.sigmafour.net/lgt/b2/IMG_7741.jpg http://www.sigmafour.net/lgt/b2/IMG_8023.jpg http://www.sigmafour.net/lgt/b2/IMG_8109.jpg http://www.sigmafour.net/lgt/b2/IMG_8110.jpg http://www.sigmafour.net/lgt/b2/IMG_8111.jpg The Cometic head gasket http://www.sigmafour.net/lgt/b2/IMG_8164.jpg http://www.sigmafour.net/lgt/b2/IMG_8165.jpg http://www.sigmafour.net/lgt/b2/IMG_8166.jpg http://www.sigmafour.net/lgt/b2/IMG_8167.jpg http://www.sigmafour.net/lgt/b2/IMG_8168.jpg The timing belt was reused from the first build because there was not very many miles on it. At all... because the BOOM happened about 2000 miles after the install of the forged pistons. And that nice red AMR Turbo. Well - I have been wondering about how to do this but that AMR almost needs it's own thread but I am just going to put it in with this thread, because there are so many twists and turns so try and keep up.

I Donated Too sigmafour Posted January 31, 2017 Author I Donated Too Share Posted January 31, 2017 The AMR story... where do I start with this one? Well... When the last engine went boom I took the turbo off and I actually ended up in person down to AMR to their old place in Center Ave, Mamaroneck. I explained the situation with the failure and while I was very confident the FP filter had caught any debris I wanted the turbo to be clean and safe. I met with Rob (He and his father own AMR) and we discussed what was to be done. It would get an inspection and we discussed a new larger compressor wheel, depending on what size he could fit in the housing. I was seriously excited about what AMR could do after being told how they do all the work in house. It went in looking like this: http://www.sigmafour.net/boom/IMG_3767.jpg and came back THREE months later looking like this: http://www.sigmafour.net/lgt/b2/IMG_6900.jpg http://www.sigmafour.net/lgt/b2/IMG_6901.jpg http://www.sigmafour.net/lgt/b2/IMG_6902.jpg http://www.sigmafour.net/lgt/b2/IMG_6909.jpg http://www.sigmafour.net/lgt/b2/IMG_6888.jpg http://www.sigmafour.net/lgt/b2/IMG_6899.jpg Looks good right? Better be... It cost $700 and AMR were careful not to include a receipt but I was told there would be a surprise and BOY they were right. I thought it was the red housing but I think they fitted that out of guilt. I would call Rob from time to time to find out how the turbo was getting on. I was always told he would be in touch but it was always me having to chase him. There was always a story about why it wasn't ready. Rob had told me they would be making me a custom compressor wheel and it had been flowed in CAD and it would be terrific. I was excited and believed him. I called again and there had been issues with the first billet material from the foundry and so they ordered another, there was some story about the type of material they were using and the billet cost $300 alone! I felt I was in good hands and there was always a story, a new cutting tip for their 5 axis CNC machine and how they would be extruding the material deeper than before and, well I was a sucker. I have at this point forgotten most of it and I wouldn't make too much fuss about them because at this point I don't think AMR make their own turbos anymore so who cares? I was proud though, I had high hopes for the AMR turbo - even when Alberto at Motive pointed out the side to side play in the freshly built turbo. Even when Josh at Motive who is a master Subaru tech and avid Subaru engine builder told me the dire stories about AMR - I thought and hoped it would be fine. Everyone warned me and I even rang Rob about the concerns and he told me that as soon as the oil comes on, the turbo would center and there would be no problems. I liked Rob at AMR - I believed him and I wanted to be proud of AMR - I felt good about it. I was warned to abandon the AMR and get something else but it was my choice to continue and Alberto said OK! We pressed on, the AMR was fitted and the intake was fetched from storage. Things were coming together quickly now. http://www.sigmafour.net/lgt/b2/IMG_8206.jpg http://www.sigmafour.net/lgt/b2/IMG_8207.jpg http://www.sigmafour.net/lgt/b2/IMG_8208.jpg http://www.sigmafour.net/lgt/b2/IMG_8209.jpg It was time to fetch the car. My boss helped me as I needed to rent a trailer to haul the car and so it was dragged out of it's resting place where it had sat for over a year. http://www.sigmafour.net/lgt/b2/IMG_8217.jpg And put up onto the trailer. http://www.sigmafour.net/lgt/b2/IMG_8221.jpg http://www.sigmafour.net/lgt/b2/IMG_8222.jpg http://www.sigmafour.net/lgt/b2/IMG_8223.jpg http://www.sigmafour.net/lgt/b2/IMG_8224.jpg http://www.sigmafour.net/lgt/b2/IMG_8225.jpg http://www.sigmafour.net/lgt/b2/IMG_8227.jpg And finally it was outside of Motive Auto Works ready for the engine install http://www.sigmafour.net/lgt/b2/IMG_8229.jpg Link to comment Share on other sites More sharing options...

I Donated Too sigmafour Posted January 31, 2017 Author I Donated Too Share Posted January 31, 2017 What happened to the Turbo Dujo? What happened indeed... you will have to stay tuned to find out. Some of this is in chronological order or it will make much less sense than it already does! As a sneak preview... it doesn't end well. So where are we now? Ah yes. Time to install the engine. http://www.sigmafour.net/lgt/b2/IMG_8247.jpg The engine was ready to go in. http://www.sigmafour.net/lgt/b2/IMG_8252.jpg http://www.sigmafour.net/lgt/b2/IMG_8253.jpg http://www.sigmafour.net/lgt/b2/IMG_8254.jpg http://www.sigmafour.net/lgt/b2/IMG_8259.jpg http://www.sigmafour.net/lgt/b2/IMG_8260.jpg Engine bay was prepped http://www.sigmafour.net/lgt/b2/IMG_8261.jpg http://www.sigmafour.net/lgt/b2/IMG_8256.jpg And then Alberto told me to put the camera down and get on with it. It was a late night and we got it done. Some of it was vague because of libations and because we were working as friends. No rush, no clock. Woke up the next morning and it was at least in the car. http://www.sigmafour.net/lgt/b2/IMG_8264.jpg http://www.sigmafour.net/lgt/b2/IMG_8265.jpg Because of the damage to the previous engine. Anything suspicious where debris could hide was tossed. There was too much spent on this engine to risk anything. New AVCS components and new oil cooler. http://www.sigmafour.net/lgt/b2/IMG_8266.jpg http://www.sigmafour.net/lgt/b2/IMG_8610.jpg I am not one to paint things that don't need it (Shout out to JMP!) but it is nice to see a clean block under there.

I Donated Too sigmafour Posted January 31, 2017 Author I Donated Too Share Posted January 31, 2017 The car sat for a few more days until I was able to come back when the garage was not too busy and carry on. Car went back on the lift and I set about installing the rest of the engine parts. http://www.sigmafour.net/lgt/b2/IMG_8273.jpg http://www.sigmafour.net/lgt/b2/IMG_8459.jpg http://www.sigmafour.net/lgt/b2/IMG_8460.jpg http://www.sigmafour.net/lgt/b2/IMG_8461.jpg http://www.sigmafour.net/lgt/b2/IMG_8462.jpg A mix of Devil's Own Methanol parts and the original AEM components. More on this later too! http://www.sigmafour.net/lgt/b2/IMG_8531.jpg It's starting to look alright! http://www.sigmafour.net/lgt/b2/IMG_8532.jpg Filling it with coolant next... http://www.sigmafour.net/lgt/b2/IMG_8534.jpg http://www.sigmafour.net/lgt/b2/IMG_8535.jpg And then it unfilled itself. http://www.sigmafour.net/lgt/b2/IMG_8558.jpg http://www.sigmafour.net/lgt/b2/IMG_8559.jpg Finally it was time! The engine started... After quite a few tries. It worked a lot better when we remembered we had pulled the fuel injection fuse. I have a video of it starting but it's not that exciting. I will stick that in here when I figure out how without putting it on youtube. It's an engine... starting... you know how that goes! It started, it ran, we quickly drained the oil and we put in some special stuff. http://www.sigmafour.net/lgt/b2/IMG_8544.jpg And then I was able to start driving it again. But since it had been over a year since it had been on the road - the first stop was to get a safety inspection so it had a current sticker. The previous one had LONG since expired! http://www.sigmafour.net/lgt/b2/IMG_8557.jpg After some careful break in miles. The next stop was going to be the dyno! http://www.sigmafour.net/lgt/b2/IMG_8724.jpg Link to comment Share on other sites More sharing options...
Dujo Posted February 1, 2017 Share Posted February 1, 2017 I can tell how old some of those pictures are by what's not in Alberto's shop. That clear blank wall next to the lift is freaking me out. There's a huge shelving system and tables and transmissions and engine blocks and all kinds of stuff there now that's not there in the pix. And that stuff has been there for a while. I can see this story progressing in time in the photo evidence of somewhere I've been. Neat. Keep it up. Don't recognize the dyno room though. Where is that? That's not Bren's new place, is it? Pretty sure it's not EFI. Love the blue Subaru on the timing belt cover. And I totally recognize all that blue nail polish on the torqued bolts. Got lots of that in my engine bay. Got any pink? They love that for the alternating color. Also, I'm a little surprised at the 850 sidefeeds. Especially with all the changes you made with the fueling system. Any reason why you wouldn't go to ID1000s? Is 850 really enough to feed 500awhp? Or is it 500hp at the crank? In which case, do you even really need meth? Thanks for sharing.

I Donated Too sigmafour Posted February 1, 2017 Author I Donated Too Share Posted February 1, 2017 You are correct - some of these pictures are now 3 years or more old. I lost track of time. I think I had pink or red on the bolts for the flywheel... None on the engine block. Good question about the 850's - and yes it's 500 or so at the crank I have been dyno'd at 420whp and then 400whp and the car was faster and smoother and I was told that it's 450whp "on the street" by the tuner. I don't know what the number actually is it seems neither do they and so I have no idea what the actual number might be because all these dyno's are different. Bren's old place with the Dynapack would definitely give high numbers and the Mustangs are much lower - ~405 on the Dynapack was ~350 on the Mustang in one case... different dyno, different day. WTFK?! And it is because I have meth I would not benefit from larger injectors. I just had a chat with Fahr_side about this and you can see some of his posts on the subject. Injectors need to be running at a certain duty cycle to be working properly, if you have too large of an injector then you aren't near that duty cycle, no efficiancy and you have more trouble low down too because of too much fuel. The 850's have not been a problem - except one time and it was actually during this dyno pictured above (which is ShopCT) and a part of the story I was getting to next, so read on when I next post! Do I need meth? No. But it adds so much additional torque and it provides a safety blanket on detonation. It's so much fun! At this point fuel is not my limitation. The limitation is exactly where it was planned to be - the Turbo. I built a 1000hp type engine with a 500hp turbo, that was always my plan and I stuck to it. I can assure you the car does not need to be faster and there would be a certain amount of I could make more with a bigger turbo to have a bigger bragging number but I would have a slower car. I have a good balance between power and lag and the car is an easy "daily driver" - reliable too, for the most part. I have been told if I have an external wastegate we could get more out of the current turbo - but that's not happening, I can tell you that now. I am done with making large jumps in power but the car will probably get re-tuned each year for finessing and to make sure all is well. Link to comment Share on other sites More sharing options...

fahr_side Posted February 4, 2017 Share Posted February 4, 2017 Mmm. That TMIC looks strangely familiar! And it is because I have meth I would not benefit from larger injectors. I just had a chat with Fahr_side about this and you can see some of his posts on the subject. Injectors need to be running at a certain duty cycle to be working properly, if you have too large of an injector then you aren't near that duty cycle, no efficiancy and you have more trouble low down too because of too much fuel. The 850's have not been a problem - except one time and it was actually during this dyno pictured above (which is ShopCT) and a part of the story I was getting to next, so read on when I next post! What I meant (which isn't necessarily what I typed) is that it is okay to run IDC up to about 95% on good top-feed injectors, as long as that's the highest they're going to go, which means that coldest night in the dead of winter etc. Since no matter what turbos we fit, the air flow doesn't change much (if any) at idle, fitting 1000cc+ injectors always requires quite some fiddling with idle and low-load fueling which most people just don't have the patience for. Fitting such large injectors and then only ever running them up to 70% IDC is pointless and usually makes for a lumpy, unpleasant drive in traffic. There's nothing 'wrong' in doing this, in that it's not bad for the injectors or for the engine, it's just wasted headroom you don't need and more difficulty getting to a perfect tune. Obligatory '[URL="http://legacygt.com/forums/showthread.php/2008-gh8-238668.html?t=238668"]build thread[/URL]' Increased capacity to 2.7 liters, still turbo, but no longer need spark plugs.
