don't you mean 4G63? if so, then that's the engine code for the mitsubishi cars such as the eclipse turbo and the evolution. these are very strong engines and can take a hell of a lot of punishment before beginning to break, and might i add this is in pretty much stock form. i think though that a semi-closed EJ block could take just as much punishment, no doubt.

yeah but i mean u do kno that the 4g63 used in the lancer is significantly different from the 4g63 (that showed massive amounts of crank walk) in the gsx and gst. The 4g63 is quite possibly the best built 4 cylinder ever just because of the sheer punishment it can handle. That's not saying other blocks are poorly made, the SR20DET is an amazing engine, albeit that it is aluminum block with iron sleeves and breaks at about 400 HP, the EJ20 engine can handle much more past that with the right reinforcing. And about a US emissions legal 300 + HP motor, my turbo mr2 is running at 313 hp and passed emissions about two weeks ago

2.0L turbo engine, 3s-gte
it's mostly a stock jdm engine. '97 3rd gen 3s-gte engine. CT-20B turbo, water injection, S-AFC controller, dynoed at 313 horsepower (was a while ago, not sure if i still have dyno sheets, but dun really matter to me if you believe me, i kno, it's all that matters). I ran on 93 octane, and it ran fine without detonation. So i mean, i don't think it's impossible for subaru to do it. I think subaru drop the EJ25 here for their own reasons that they probably won't release. IMHO, i believe they dropped the EJ25 not as a lower quality engine or a higher quality engine, but a different application engine. In america, most of import racing and popular import racing is dominated by the quarter miles, and fast cars are rated by 1/4 mile times. You drop a 2.5L turbo engine and AWD, all the quarter mile junkies are gonna jump all over it. AWD, rev it to 7K and dump the clutch. Little spin and you're gone. In Japan, it's a different kind of racing, more turns, more freeway runs with lots of turns and the junx. A turbo 2.0L which revs high would be much more practical in this sense, allowing you to stay in your power band longer and more controlled cornering. Does one outrank the other? I dunno, i don't think so, b/c we haven't seen the true potential of the USDM STi yet...

Enthusiasts always like more speed. Anyone saying doesn’t care about power and only care handling is fooling themselves. JDM or not.
A question for you, can you tell me your modified 3SGTE is reliable enough to last about 5 year/60,000 miles? Even let’s say you can, what about this set up in other common driver’s hand? Also you said you are running on 93 octane gas, tell me you can get reliable 313whp from 91 with same set up and I call you are da man.
The aftermarket company do not have to handle any engine related warranty problem at all, however, car manufacture has to thus increase small displacement is the safest way.
HP is not a big problem. Just look Hyundai’s Pro-Rally AWD Tiburon; that little things pump out about 300hp, but why Hyundai never made it to production? They are not stupid, I am sure there is a market for 300hp AWD Tiburon.
Engine with high HP is not hard, but engine with high HP, high reliability for common driver and reasonable price is hard. Right?

how much hp is considered "high HP" for the common driver? I can think of multitudes of drivers who would consider 200 HP as high HP. and my modified 3s-gte hasn't had any modification that would tear down the reliability. WI is mostly for anti-detonation, as well as the S-AFC controller. There are scores of MR2's who are running 12's, who have unopened internals and almost 200k on their motors. I think that's reliability. If to run on 91 octane, you can always set the alcohol level in the WI system up more, tho it would be more of a custom WI system.
Of course enthusiasts like speed, but can you really effectively put to use a car with over 1000 hp on a street car? CAN you put 1000 HP on a street car? No, of course not. (street car as in car running on pump gas that's not pump gas at the local track =P)
And the things is, that even with 313 hp, i don't have to boost 20 psi each time i drive, i usually stay at vacuum, thus never putting addition stress on the engine...
hehe my mind wanders here and there, so forgive the inconsistency

that's where the WRX's, evolutions, STi's, etc. come into effect. i think it was JUN's super lemon that had about 500 or so whp and had the ultimate handling package to make that car one of the fastest track cars. what good is turning at 1000hp, when all you're going do is either spin out or lose control. it's just physics. i agree, what is "high hp" for the common driver. supras and skylines can get up to 600 to 800 whp and still be a daily driver, as far as reliability goes, i'm not sure, but it is still considered a street car.
exactly! everyone here always wants the absolute best car out there. i mean, it all shows when the evolution and the STi both came out. everyone wanted to know "which one is better" and the answer to that was that they were absolutely the same, they are both great cars, and have their ups and downs. and there were those that were nitpicky about 1/4mile times, this and that, some even got pissed off when one magazine or few said the evolution was actually better when in fact, it was just simply a matter of opinion. it was simple. drive them both and produce your own opinion, or just simply pick one. both the STi and evolution are so close in comparison and have and will be for many years and years to come, which is the reason for the on- going historical battle between the two, pushing each other company to the top. now, where there's one thing, there's always one better. just make a choice and stick to it. and yes, every car is different, just pick one that you feel is best suited for you. that's the reason i chose the WRX and not the STi. and i'm sticking to the WRX.
