ecoflame Posted January 2, 2013 Share Posted January 2, 2013 In October I spun a rod bearing, cylinder 1 I believe. After much deliberation and forum browsing I have decided on my course of action; 1. I am keeping her N/A. She's going to be my DD. 2. I want to rebuild the motor I have. 3. I want to build it better than stock. 4. I want to keep all "upgrades" within the stock ECU parameters. I have done some basic research bouncing around forums, and this is where I'm at parts wise. Of course this is speculative, and I welcome additional information or opinions. BUT PLEASE KEEP IN MIND MY 4 OBJECTIVES ABOVE. STI oil pump or after market oil pump (I forget the name, I have it written down somewhere). Anything bigger then 7mm. Port the oil pick up lines for smoother flow. Eagle piston rods (they'll be needed down the road) Pistons I'm not sure on, hoping for insight from yall. '04-'06 EJ257/255 head gasket -p/n 11044AA642 Port and polish heads, intake and header to match. Delta cams - stage 2 regrinds? Valve train leave alone? New valves and stem seals '05 RS engine mounts, GrPN trans mount, urethane filled differential mounts. This will ease the bucking when letting off the throttle? Yes? Hypersingle clutch with spring hub and lighter flywheel Oh and light weight pulleys. I welcome all opinions and advice, so what do yall think?

ripemeat Posted January 2, 2013 Share Posted January 2, 2013 why? and who's/how are you going to tune it once you do all these mods? it's been tried and tested to the point of diarrhea & vomiting on NASIOC and 2.5RS. building n/a subaru motors comes out to be widely not worth the cost for what you gain from it. that is why so many GC8 guys do bolt-on turbo kits at like 3psi, and why 3rd gen legacy guys do sti swaps.

FJuan Posted January 2, 2013 Share Posted January 2, 2013 ^^ Exactly Without upgrading your ECU to recalculate for the additional air/fuel, the motor is going to run rougher than you think. My wife's balls are delicious. Link to comment Share on other sites More sharing options...
ecoflame Posted January 2, 2013 Author Share Posted January 2, 2013 Why - because I don't have +8k for a STI swap. I'd like to maintain a DD aspect. And I don't feel like spending one too two months merging the two harnesses. Most of what I have compiled came from a guy on RS25 who did a N/A build and made some decent power at the wheels. Now I far from expect the output he made, he did some serious and respectable work on his ride. I just want this motor to be the best it can be. Also I'm not a huge fan of boosting vehicles that didn't come with a stock turbo. Personal preference. I'm trying do to as much as I can with out tuning. From what I've come to understand my ECU isn't tuneable and piggy backs just cause problems. Link to comment Share on other sites More sharing options...
ecoflame Posted January 2, 2013 Author Share Posted January 2, 2013 Also aren't the cams the only mod that would require tuning? Link to comment Share on other sites More sharing options...
ripemeat Posted January 2, 2013 Share Posted January 2, 2013 cams, pnp head, and pistons(which would mean your CR would probably change a little) are all issues that need to be tuned for. plus, how do you think the engine is going to make power for these mods? the engine isn't magically going to be faster with physical upgrades, you need a tune in order to allow for the performance to happen. it's just not a good thing to dump money into. you'd be better off just finding a suitable replacement and DD'ing it.

ecoflame Posted January 2, 2013 Author Share Posted January 2, 2013 Cams and Pistons I can agree with, PnP eh I dunno about that. I'm not trying to start an argument, but how can you say the engine wouldn't be faster with physical changes??? Different cams means a longer or shorter duration of the valves opening, direct effect to performance. A change in CR, direct effect to performance. Granted you do need to tune to maximize the changes made, but to say simply changing the parts won't benefit the performance is naive. Having said that I thank you for your input.

compsurge Posted January 3, 2013 Share Posted January 3, 2013 What you want is a completely stock engine. </thread> I'm not bashing you. I'm being completely serious. If anything, get groupN motor and transmission mounts, but skip the pitch stop, as it's not any different with the groupN. Don't get a lightweight flywheel or a crazy clutch setup on a car that doesn't need it. You will hate yourself every time you have to change gear in your daily drive. You can't build that engine better than Subaru did, especially since you aren't going to run a standalone/tune. Link to comment Share on other sites More sharing options...

bomberlegacy Posted January 3, 2013 Share Posted January 3, 2013 I saw a show one time, they took an Impreza and put a high flow intake and exhaust on it and lost horsepower. Then had it tuned and it was well over the stock level. Point being, our ECUs are picky and any little change in airflow needs to ecu work. tuning all of that plus higher octane would be good plus removing the drive by wire delay is nice. What are your plans for it in the future? All the mods you have mentioned even with a tune won't help the n/a all that much. You need forced induction.

ecoflame Posted January 5, 2013 Author Share Posted January 5, 2013 Future plans are just keep it DD. Now if something horrible happens to the motor (knock on wood) that's opens up new options. EZ30 more then likely. I'm just trying to give her more pep in her step. Without shoving air down her throat. Link to comment Share on other sites More sharing options...
bomberlegacy Posted January 5, 2013 Share Posted January 5, 2013 Only my opinion, but if it is just going to be a daily driver, rebuild it without spending extra on beefy rods and pistons. Delta cams would be nice and cheap. I am not sure if the OEM valvetrain will be sufficient. Then tune it for the best gas you have in your area. The tune will make the biggest difference, performance will be worse if you don't.

Brprs Posted January 5, 2013 Share Posted January 5, 2013 H6 swap. Done. The whole n/a 4 cylinder high comp bs has been beaten to death. Yes its cool to say you have a decent amount of power naturally, but you'll be out of money very fast. Being able to drive it every day comfortably is most important in a daily driver. Best to leave it as is. Link to comment Share on other sites More sharing options...

Swap in a rebuilt EJ251 The build idea is great but I doubt it will "wow" you as much as you think. The DD aspect is essential and a properly maintained EJ will run for 100K's of miles You could also swap in a EG33D like someone mentioned above would be a great engine to run with a MT. There is a decent amount of work involved but you seem to be up for the task. Link to comment Share on other sites More sharing options...

You wouldn't believe the overall cynicism I've encountered trying to get this project rolling. I would love to throw a EZ30 in to her but I've decided I don't want to mess around with merging harnesses. Honestly I'm not looking for a huge WOW factor with her, my "WOW" car is my Accord. AKA the V8 eater . I just want a lil more umpf when I accelerate through turns and curves. Link to comment Share on other sites More sharing options...

Nice and for a nice WOW out of a N/A H4 you could go with a EJ25 bottom end, EJ222 (thats a phase 2 EJ22 not the EJ22E version 2)heads, Delta 1500's (the 2000s aren't as "streetable"), thinner HG to bump the CR up to 10.5:1-ish and run 93 OCT, slap some EL headers on there for a few more ponies and youll have a nice screamer! Yeah the H6 drop in would be nice but the harness merge can be mean things like making the tach work properly and speed sensors are often overlooked by folks wanting to take the swap by the horns Link to comment Share on other sites More sharing options...

I was contemplating all that but I don't want to mess with tuning or swapping the ECU. There's a guy on RS25 who did all that and made one badass mofo motor. Future build maybe . For now I'm just going to; PNP the heads and header. Maybe the intake mani. upgrade the oil pump and smooth out the oil pick/ return lines Delta 1000 cams and haven't fully decided about the valve train and springs. I love these lil emoticons!
