as i stated, i was just wondering if it was doeable.....funny thing is my ej25d has no leaks, compression, oil, or otherwise. still has factory head gaskets. what about boosting the n/a at a light boost, say less than 8psi? grenade? maybe i'll, nope, no more fog for me! nitrous is the devil!

 

you have no idea how good that makes me feel

 

i was THIIIIIIS close to getting a zex kit

 

im turbocharging my ej22 instead. the thread is idling somewhere in the n/a forum

 

edit- found it

i'm just wondering....for reasons that are unknown to me, i can't find any info on this...maybe i'm retarded. if that's the case, yeah, they have a name for it! can a eg33 from, say, a 1996 or 97 svx be transplanted into a 96 bd? not that i'm doing it, but, i might.....still on the fence about a lot of things with my ride. so many different avenues....what to do.....this quote keeps coming up when i think about turbo or not......btw, been in foggyland(which is no fun until you dump at least 75shot or higher) done with the 40 dollar bottle refill...back to the quote..."there is no replacement for displacement"-corky bell. what to do?

 

I have been on a tear about EG33 engine info... I got a splinter in my brain to mentally plan out an EG33 twin turbocharged mid-engined car.

 

All of the information that I get about EG33 engine swaps is that they can be done, but it takes some fabrication to fit them into any other Subaru engine bay, aside from the SVX.

 

The Legacy and Impreza engine bays are shorter, and the crank pulleys try to occupy the same space as the radiator, when the longer EG33 engine is used. Some folks have re-located the radiator a few inches forward with pusher fans, instead of pullers.

 

But that is a lot of work when an EJ-series turbo 4 fits right away, and makes as much power as a normal EG33.

a mid engine subaru?

 

that would be SICK

I was browsing for potential upgrades for Legacy L '98, and stumbled upon this page:

http://www.yourhotcar.com/product/list/1998/Subaru/Legacy/Performance_Parts/Performance_Chips/

 

It looks like something one could get off eBay and make anyone who sees it under the hood laugh out loud. Or is it something that is worth looking at? They make pretty bold statements, like +35HP and +40HP, so bottom two alone theoretically give around additional 70HP.

Does anyone have them? What's the common wisdom on such upgrades?

nobody has those.

 

i imagine theyre total bunk but..

IF they do what they say they do (intercept/trick sensor readings) then theyre WAAAY over priced. you can make those adjustments on your ecu for <$100 and tune for those things the right way

On eBay, anything can sell, because majority of consumers buy things on impulse, before doing due diligence check. And what is even worse, they still leave a positive feedback, because of concern for the feedback that seller will leave.

There should be a dedicated thread for eBay, internet junk/semijunk and misleading products in general.

i wonder where ppl come up with this crap..

 

with good imagination ANY performance mod is possible, for example,

 

"easiest way to improve your car milage! Save money on gas! This upgrade creates very high frequency vibrations of air within car tire, forming a thin region of lower viscosity air on inner surface of your tires, thus reducing the energy required to overcome rotating momentum (due to shear stresses) of the air by reducing friction between tire surface and air inside"

 

Notice how here it doesn't even matter if any of mentioned physics principles have anything to do with reality. In fact, I'm pretty sure, that if someone would come up with a flashy name for that "mod" and some convincing method of inducing tire vibrations, without making it look like a too obvious scam, I guarantee it would sell.

"Sign me up!" lol

 

 

Napping's got the right idea. :-0

 

Here's another one, came up with it this morning:

Disclaimer: Below is a load of BS, such product does not exist, will not exist, and physically cannot exist, though some day, someone, might try to sell it anyway :).

 

"Why spend 1000s of hard earn $$$ on expensive intakes, noisy turbos and other last century technology. We live in 21st century! There are modern high tech ways of improving your car performance, while reducing emissions.Try the new product of our next generation car tech, the H2Infusser sticker.

Product requires no professional installation. All you have to do, is to fill up full tank of gas, take a soft lint-free cloth, soak it in cleaning solution and clean a patch of your gas tank on outside of the tank. Than peel of protective layer off H2Infusser sticker, and apply the sticker to cleaned gas tank area. On inside of the sticker is a hydrogen saturated surface. Once it comes into contact with metal, gas tank surface acts as a catalyst for reaction and hydrogen is released from the sticker.

Hydrogen gas has ability do diffuse through metals. Thus, since other side of the sticker is special film, that is impermeable for hydrogen, it has nowhere to go but into gas tank. Unlike in water, hydrogen gas will no accumulate at the top of the tank, but will attach itself to benzene molecules by weak nuclear forces and stay diffused in gasoline. after gasoline takes its trip to engine cylinder, compression stroke of the engine will compress gas mixture, which will raise mixture temperature to a point at which hydrogen breaks off benzene molecules and then, after spark is fired, it burns just like gasoline does, except it produces significantly more energy, causing much more powerful push on a piston head, thus more power, and of course, since it's hydrogen, it produces water as byproduct. However, the amount of that water in so small, that there is no need to change catalytic converters or muffler. Amount of hydrogen per 6.25 sq. inch sticker is enough to 'upgrade' ~200 liters of gasoline. How often you have to change stickers, depends on your car gas tank and car millage (which is now going to be much better thanks to sticker). Avoid using other fuel additives while using H2Infusser:cool:"

nah, I'm not evil enough. and speaking of material science abuse, I know, my conscience had hard time letting me even type it..., But that's exactly the point, if yo throw some cool words into an ad, regardless of the legibility of content, there's always someone who will think "I don't know WTF does any of that mean, but it sounds too cool to be fake"

 

on other hand, this one isn't much different in terms of BS per square inch of page.. http://www.fuelmags.com/index.php .... just sad :(.. I mean, if you are an auto mechanic, and you see a customer, who came into garage complaining about some engine problem he or she is having, and then you see a magnet clamped to fuel line, would you pass an opportunity to charge 10x and justify it by "need to tune up the Carma field of solenoid" or something...

 

Isn't there a law or something that prohibits scams like that???

Depends on what they claim. If they put that lil "results not typical, individual results may vary" thing in there, for most stuff they would be ok. It is sad that in the heat of high gas prices people will believe almost anything.

 

I mean, we still have people that think they can take a pill / cream to enlarge certain parts of their bodies.

 

But they are talking all "technical" it must be true! Also some shady mechanics (not shade tree) have been doing this for years (headlight fluid, second transmission for reverse.....)

Add to that a new midpipe. Some people throw on throttle body spacers (apparently good for a few HP), grounding kits (may not create power, but helps smooth the motor out and some claim MPG increases), maybe some Sea Foam to clean it out if there's a lot of mileage on the motor (regain some lost power of a dirty motor).

seafoam:

use varying amounts on the bottle for each application ('X'oz threats 'y'oz)

-put in it your gas (dump it in the filler neck)

-put it in your oil (run it for one tank of gas [w. seafoam!!11]) and change your oil out when you're done (swap the filter too)

-pour it into a vacum line that feeds all cylinders (brake booster, etc. i used the pcv) while the engine runs and keep your hand on the throttle as you pour (or keep your buddy in the car) to keep the revs up (you dont want it to stall with this fluid inside). let the car sit after it smokes out your garage and you need to leave. fire the engine back up and go for a drive with plumes of smoke bnehind you (do it on a sidestreet for safety sake)

Sure, straight from our pm's :lol:

 

Yes, Delta doesn't keep cores like Cobb or TWE, so you have to send your cams in, or buy a used set of cams (that's what I did, the seller offered to send it straight to delta so I save some on the shipping) and sell yours later when you install it. you can check out RS25.com's NA tuning section and NASIOC NA tuning about the delta cams too.

 

They offer two grind profiles now, one mild and one race (or spicy as Cobb puts them). http://www.deltacam.com/ is the website. You'll need to call them up and talk to them about your engine and stuff so they can recommend to you what profile will suit your needs.

 

And yeah, regrind just means they change the timing of the cams by grinding down/adding some material on the nubs that open and close the valves. According to their website, they also inspect the cam before and after the grind on a cam-reading machine of some sort (it's like a follower that traces the profile on the cam nub).

 

Their setups isn't as aggressive as comparable profiles from TWE or Cobb though, but I'm guessing since Delta isn't a Subaru specialist (they seem to do a lot more V8's and the like) they didn't want to push the envelope too much, but I got my SOHC cams reground for $161 for the mild profile, with the return shipping included (I had the guy I bought my set from send it straight to delta)

 

http://forums.nasioc.com/forums/showthread.php?t=1224817&highlight=skidd

 

See that link for a quick vid clip and impressions from someone who installed it on his RS.

 

Typically for the mild cams it's around 12-15hp+ gain by itself. The typical route is add the supporting bolt-ons, exhaust, intake, equal-length header, and you're looking at around an honest 200bhp from 165bhp.

 

Add highflow heads to that ($$) and you're making a reliable 220bhp out of your NA car.

 

Thanks and a lot of good info there. A few things have changed since the writing of this though. We have several grinds on the shelf and ready to go. We still prefer that you call us about your build so we can get you the right grind that suits you best.

 

We also now do Subaru heads. Which include, new stock sized valves, oversized valves, porting and polishing, complete packages for all you performance needs.

Unfortunately both sites are being reconstructed. We are trying to get more user friendly pages that are fully functional. You input your choices and the site will give you a quote right at that moment.

 

Feel free to call us @ 1-800-562-5500
