Highest HP 4g63 engine (from 2007)
http://www.gohypermax.com/Catalog.as...5-7bafa7d100dc
I know it has different cams, pistons, rods, yada yada.. everything is revised pretty much. Ive built my evo from BR Assembled shortblock on up two times now, and owned older dsm's so i know how the 4g63 "evolved" over the years.
Mitsubishi took what they had and made it better.. if there was a flaw in the frontcase, they revised it.. if there was a flaw in the oil squirters, they revised it.. they revised pretty much everything.. the evo 8/9 is pretty much a fine polished 89-92 6 bolt dsm engine with a 7 bolt crank. (Power handling wise, looking at it from a USA perspective - Because we did not get any evos until 2003)
The funny thing is look what they did in 89-92 .. they had bigger rods (nicknamed the 1g Big Rods Handling 500WHP+ back in the day, which was astronomical back then for a import with a little 2L to handle that kind of power with stock internals) and a stronger design in general.. then later down the years they introduced the 7 bolt with smaller rods, weaker internals.. and also had a flaw in the "check valve style" oil squirters introduced in i believe 95.. which some believe (magnus motorsports) caused the crankwalk issues. (DSM side of the 4g63) When the crank got excessive play, it would move the trigger plate (attached to the crank) enough to dig up the crank angle sensor and then your car would no longer operate anymore after it destroyed the crank angle sensor.
Why are you quoting a 5 year old magazine, when its 2011 now. AMS was constantly changing their Evo's, and current (since i live in current state and not past) it is a gutted out evo as we all pointed out.

Hi,
I had to much work, sorry i late to show u the GTX test we have done, but i have good news.
We test the standar GTX3582R and a modified one to our test car, so as to compare.
The modified one is not for sale till spring, just for our test.
The test car uses our high efficiency race engine with 13:1 and stage 2 cams.
We will not test smaller gtx3071 and 3076 to this engine as will outflow them at 14psi. We will propably use lower efficiency engine for these tests.
We used to this test: a speed sensor monitoring the shaft speed per boost. a boost gauge to the exhaust manifold to see turbine wheel and housing efficiency, and temperature sensor to compare to the therm comp map.
Here are some quick pics.
Give me 1 hour to upload the dyno plots and pics of the 2 turbos we test.

Ya i was only referring to the block.. Thanks.
So the lancer evo since 2000 till present are all pretty much built the same minus pistons, crank, cams, misc gasket redesigns / sensors, etc? same rods? I remember seeing an article comparing rods, and they were slightly different / smaller between each year.
I only know the dsm side history of the 4g63 2003 on down, we never got evos in us until 2003 so i do not know any info from then on down with evo's.
its very apparent tho that the internals in the evos to date are comparable to the oldschool 6 bolt 89-92 blocks that were notorious in the dsm's for making nasty power. Its what got people realizing the 4g63 was a stout *** motor, and set itself apart from the other 2L turbo engines out there. I also know the joint venture was dissolved in 93.
Not sure if you follow the dsm side of things being in germany?

I also know that Evo7 Valves work in DSM heads, so not much of a different's here either.
I just know DSM stuff because I own one, but you can also find a few Evo1-2-3 (4-5-6) here, so its easy to compare the cars side bye side.
Evo1-2-3 does have the same block as 1G DSMs with a crank like the 2G DSMs and an head like the 2Gs.
In my opinion headrunners where never bigger than in the 1G or Galant VR4.
For streetcars thats not important, but when it comes to peak power, that is where the 1G head shines.
Evo heads are just build to give massive mid range torque, like you need when doing a rally

I suppose it just comes down to the perception of "light years apart." To me, and most everyone here, to be light year's apart would imply different measurments, different crank and a different block design. All the advancements you named are tweaks on the same basic design, and because of that the 4G63T in the Evo can trace it's roots as bark as the mid 80's I think, before the DSM, before the Galant VR-4 and all the way back to the Lancer EX 2000 RWD like other have said.
