fightinchunk Posted October 15, 2012 Share Posted October 15, 2012 UPDATED courtesy of superbitchstorm sandy So i've been building this legacy, an 05 GRP LGT non limited in 5speed. Got the car for 3k with blown turbo. A friend of mine from manley has been working on this boxer motor that's theoritically supposed to be the most effecient boxer than the apparently highly inefficient 2.5 and 2.0 motors. The block is 1. pinned for additional cylinder rigidity 2. oringed 3. built with all manley forged internals. both the piston and rods are prototypes made specificially for my HC motor. It effectively destrokes the motor to 2.35... 4. bored to 100mm 5. killer b pickup 6. 850cc DW injectors will be running a 20g and FMIC for the time being... will be dynoing with both that and a stock location 35r to see which would be better for the application the theory behind the motor is that it'll spin to close to 9k with the proper headwork, 11:1 compression will give great NA performance off boost. but boost lag will be reduced tremendously by the faster spool that 11:1 compression gives. It gives the motor a perfectly square bore to stroke ratio. have no idea what to expect but the car made 550ish with a smaller hta68 at around 19psi when the motor was run briefly on a forester. car should be getting tuned in the next couple of weeks by Dave Brown from MSPT(autoperformance solutions) when I bought her http://sphotos-a.xx.fbcdn.net/hphotos-prn1/74121_710762718779_4075279_n.jpg you can see the block is pinned in the water jacket around the cylinder. as close to a closed deck block as a subaru can get, but with the benifits of cooling of an open/semiopen deck would provide! Also oringed for custom headgaskets http://sphotos-b.xx.fbcdn.net/hphotos-ash3/559211_10100268031664319_1620770264_n.jpg getting the car all put together at broken motorsports! http://sphotos-a.xx.fbcdn.net/hphotos-ash3/541991_10100332446466539_230590137_n.jpg http://sphotos-b.xx.fbcdn.net/hphotos-prn1/155140_10100332494370539_1727391918_n.jpg stay tuned for dyno numbers! the numbers wont be high i think... but according to both dave brown and tom(manley)... the motor should "smack me in the face like a v8" Link to comment Share on other sites More sharing options...

Berzerklo Posted October 15, 2012 Share Posted October 15, 2012 11:1 compression ratio in a turbo? What is your boost target going to be?!? Link to comment Share on other sites More sharing options...
GEE-OTTO Posted October 15, 2012 Share Posted October 15, 2012 With such a high CR, 93 OCT, timing and high rev you could get away with not too large snail and still make insane power. Cool idea, we 2.5i guys get the benefits of higher CR and the AVO turbo kit. Link to comment Share on other sites More sharing options...

fightinchunk Posted October 15, 2012 Author Share Posted October 15, 2012 11:1 compression ratio in a turbo? What is your boost target going to be?!? hoping for close to 18psi like the previous prototype that went into the forester With such a high CR, 93 OCT, timing and high rev you could get away with not too large snail and still make insane power. Cool idea, we 2.5i guys get the benefits of higher CR and the AVO turbo kit. i kinda wanted to see how it'll respond to a quick spooling turbo but the tuner to not be scared with a turbo that would typically be laggy on stock compression sti's... for it wont be laggy at all. damn...an LGT for 3k...crazy yeah... saw the guy at the post office, told him i loved the car and that i'd buy it... asked me to make an offer. threw 3k out there and we settled on 3.5k. the car was mine by the end of the day Link to comment Share on other sites More sharing options...

BAC5.2 Posted October 15, 2012 Share Posted October 15, 2012 You can't "destroke" the engine with pistons and rods. You must have an EJ20 crank in there. A 35R is going to be too much for that high CR, low displacement, and pump fuel. You'll fight det the whole way. If you use E85 or race fuel, then you might be able to hold onto it and make that turbo rip. If it's a street car, I'd look into the GTX3076. Hopefully those pins keep the stock sleeves from bursting. I have my doubts, however. Stock sleeves almost invariably fail with 100mm pistons, and the engines become VERY det sensitive with that little sleeve remaining. The closest you can get to a closed deck block in a Subaru, is the OEM closed deck block from the 91-94 Legacy Turbo (EJ22T). And this all begs the question - What are you doing for transmission? That much power will vaporize the stock 5MT if you drive it like it should be. If you go for 600+, even a stock 6MT will be ill suited for the power (not to mention short-legged in the ratio department). What's your plan?

Max Capacity Posted October 15, 2012 Share Posted October 15, 2012 I was also thinking about the tranny after he get's the engine to hold itself together. I hope you have a Great tuuner, You might want to contact Devin Perice at AEM. I see your in central NJ. There are a lot of great tuners there. Is the car going on Motec ? May be look up Jeff Evans of Evans tuning, or Felix Media off the Honda forums, like Honda-Tech.com I can't remember whats the name of the shop Felix works at. What my main point is you need a great tuner. Here, I did some searching for you. http://www.google.com/search?q=gato+tuning+nj&sourceid=ie7&rls=com.microsoft:en-us:IE-ContextMenu&ie=&oe=&safe=active I know Felix has tuned other cars as well, I know theres a Ford GT40 he has done. At least ask them for help and if they won't touch the car ask them if they know who would. Mike at AZPinstalls.com may be of some help too. I'm trying to find a better link to Felix but it's hard here at work... 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD).

ripemeat Posted October 15, 2012 Share Posted October 15, 2012 interested to hear the results. I do know that people that try to go north of 9:1 CR run into det issues as BAC5.2 said, it would be a challenge on 93 i think. I'd say to get the best results would be to introduce meth injection in this scenario.... that will help with running a somewhat average timing advance as it will be tough on 93 if i had to guess. and boost, well, i dunno, we'll have to see Link to comment Share on other sites More sharing options...
Max Capacity Posted October 15, 2012 Share Posted October 15, 2012 You may want to check out FTW race fuel too. Some of the import drag race guy's are having great luck with it.

Kevin from speedfactory is insanely fast. His civic was pushing 900whp last year. His turbo is upfront with the fmic, connected directly to the hot side of the fmic. It is an amazing setup to see in person. I took some classes with him at TCC in tacoma. His brother James and him are wicked smart. Link to comment Share on other sites More sharing options...

Their shop is pretty intense now. James is tuning like crazy nowadays. I've heard from Kevin that they are having a difficult time keeping steady numbers above 1100whp.
