Wow that other thread on IWSTI was harsh, but Epic Fail is a bit strong. I wouldn't agree with the statement. Anyway, they really bashed the hell out of you for owning a GTO, your quarter mile times, etc. A couple years back IWSTI was not that bad (maybe my memory is wrong). They have become very defensive about the new GDs. Really; you can disagree with the poster, but why attack them personally? Its just an opinion.

DGMSTiWagon, I appreciate your posts in here to bring a different point of view.

My experience with the EJ257 on my 04 STI did not go well though I loved the car dearly. If only I could have a STI with a 4G63.

Yes it was harsh. Based on my expectations for the car after driving the previous model years I think EPIC FAIL was well suited. I really like the outside of the car, but from the moment I got inside it till the moment I got out of it I was very let down. Maybe having drove the prior models and having seen the 36XXX dollar window sticker I had just set the bar too high.

GTO FTL apparantly.

just kiddin around about the .02 seconds thing dude.

but neway, i can feel that i've over stayed my welcome here. i'm gonna go back to where i belong. have fun with your cars!

Man, don't leave! We were just starting to get along! You're welcome to stay and get y0 post on.

great debate guys i am learning alot...

im back

i just did a search on Nasioc. It appears stock 2.5usdm ej25 can handle about 400-450whp on stock internals. has it failed? yes. has it not failed for thousands of miles. yes? i guess it's how you drive and maintain it.

i know you're entitled to your opinion, but lackluster? cmon now.

for 35k and you can load up the hatch with a bunch of shiz and go toe to toe with sports cars more expensive... far from lackluster.

DGMSTiWagon

just something if you haven't seen it.

not too bad right? i'd be satisfied with this.

also, the other night i was driving home, and i spot a WHITE EVO X from afar. I got excited because this is the second one i've seen. anyway, i speed up to, obviously, do a quick pull... and. it wasnt an EVOX. it was a regular lancer with a wing and everything. looked good, but i was disappointed. i've only seen 1 EVOX around MD. it was red. I've seen 4 08STi's. 3 grey ones and a black driving around. what's the deal?

Agree what a ****ty stock turbo Yet a lot of people forget about it and compare how their evos with their 41-42 lb min turbos put down better numbers on bolt-ons than sti's with their 35 lb/min turbos... lol You to do it at the end of this post. (how you haven't seen 08 STi get close to the X power )

Oh really? a 79mm crank will have a higher piston speed than a 86mm crank The EJ257 do not rev that well because of many factors... oiling issues at high speed, piston weights (large bores)... Also our heads are not the greatest... So if we don't make power at 9,000 rpm then why take it there. But we in PR (I'm from there) have made great progress with this engine, enough to be competitive with anything else. 800+ WHP all boost and running low 9's like most streetable evos on 42R. Even streetable 40R subies in the mid 9's all boost.

This I don't agree with this to a certain extend... You see we have mounted turbos in front of the engine and the benefits were minimal. Maybe when you have small turbos < 50 lb/min you might see some benefits... Other than that just look at the drag cars from AMS, Buschur and so on... Why they have those long manifolds Optimal turbo manifolds could be somewhere between 2-3 ft in lenghts, ours are just a little longer (by default). Anyway I could spool a 55 lb/min turbo (to 22 psi) by 3,500 rpm once I took the crappy unequal length manifold out of the picture. Oh and with that went the overrated boxer rumble.

Again the difference in lag between a FMIC and shorter pipes is minimal, especially with bigger turbos. Seen it many times in my own car (I have a big FMIC). Cams have more impact on boost threadhold than pipes that are 2 to 3 feet longer. Is like those rear turbo F bodies and OP car those suffer from so much lag (you can't get much further away than that!)

All in the tune man...

<--- 507WHP (dynojet) 457 WHP (low reading MD dyno) stock block... high 10's at upper 120's.

Hypereutectic pistons got to love 'em. Brittle as hell yet strong as long as you don't get any detonation. We manage 634WHP and low 10's on the stock block (stock long block record, stock cams ECT...)

The rod bearing failures comes with detonation... Subaru engine have very small tolerances... you get some know and your bearings will suffer.

As far as the 4B11 trust me... eventually you will see 700WHP on the stock block in extreme applications. Definitely it will beat the stock 4G63 block record (The 4B11 is just a very stout engine). You guys might laugh (4G63 fans) or fanboy's might cheer... but in time you will see. Now of course a built 4G63 is tougher due to the block, but the 4B11T is truly a marvelous aluminum turbo engine.

Agree


Anyway I just wanted to clear some points.

You totally got me here. I had my 99.5 x 79.0 flipped in my AWD Excel data file as 79 x 99. These things have coffee can sized pistons, wow!

I do think the main contributor to lag is the pre-turbo piping. but the unequal length on the Subie from the driver's side makes an abnormally long crossover pipe and hurts spool.

We mapped an 05 STi on a green with an uprated TMIC, switched to an APS FMIC and made 25whp immediately post remap, but lost almost 500rpm of spool trying to charge that big core. Even with the power gain, the car slowed in the quarter mile due to less area under the curve. I think a smaller FMIC might have been the ticket.


I'm not trying to play down your accomplishments. They are very good. My point is was that mid ten second and faster Subarus are an exception rather than a rule. There are just a lot more fast Evos (CT9A 4G63s).

Great post and flawless victory on my piston speed goof.

i wish more people on forums are like this. it's good to see EVO and STi guys talk about serious car shiz without it becoming a bash fest. I'm actually learning more just by reading.

i dont know much about cars, the most i've ever done myself was swapping an EJ205 from an 03 WRX into my 2000 Impreza 2.5rs coupe. took a good 2 months and the wiring was a big headache, but hey, the car was a beast IMO for what it was. aside from that, all this stuff about internals, i dont know jack.

We may forget about the smaller turbo's in STI's... But we do not forget about the 2.5 liters vs our 2.0.

Personally speaking though, I love Subaru's. Like almost everyone else, I looked into the 2005 STI when I was shopping for my VIII. I really like the company in general and my local dealer. My decision was mostly financial at that time. I ended up getting an 04 evo in early 05 for around $1,500 under invoice. I traded my VIII for a X for problems related to crappy installs and a horrible tranny build, that's another story. I didn't really like the direction Subaru went with on the 08 STI, but I still respect it for what it is.

JGC

Yeah that's the APS FMIC, the core itself it's good... but everything else is like most APS products (Headers that crack, turbos that don't perform and Intercooler piping that completly sucks )

I lost about 100-200 RPM of spool from a spearco TMIC to my FMIC.

RS-0

ACTUALLY, to be technical, all of those failed examples were brought to you by failed EBC trigger fingers + knock + a sprinkle of weaksauce.


The EJ205 is not that old, btw. The EJ20G is...

I love my turbo Forester, and so does my wife, but that XMR is chomping at the bit...bad.
