EPP '03 Turbo GA

[GA SE/T]

I did a search for EPP and found nothing so this is just an FYI of what's out there. Sorry if this is a repost. Enjoy.

internal wastegate = ghey
cryo kit = waste of money (from dyno tests i've seen and what not)
big wing = ugly

that all i can think of right now....

[Mendoza]

Anybody know how much horse that GA was pushing? I like that setup i am really thinking about getting the rsm supercharger but i am debating on which setup to do.. Turbo or Supercharger hmmmmmmmmm...........

[99Alero_Boy]

turbo.......

[ganut]

I'd like to see those dyno tests of the cryo system...... from the looks of it, it dies a fairly good job cooling the IC down..... so why wouldn't it give a good gain?

[99Alero_Boy]

from talking on stock turboed cars forums (srt-4, evo8, sti, etc...) the results in real life are a hair in the 1/4 at best, most the intercoolers on these cars already work with enough efficiency that the system doesn't do ****, even if it is freezing cold and drops the temp 50+ degrees.........the only place people say it makes a difference is on the dyno because there is not the force of air on the intercooler, dyno results vs. street tests have shown that basically the spray during a dyno test gives you the best results as far as what your car really lays down horsepower wise on the street, but once you go out on the street you might as well ditch the kit..........besides like i said above, if you really wanted a kit like this you could make one yourself for $100 or less instead of spending $300-$500.........

just my $.02

internal wastegate works just fine on a 3.4 app, especially w/ packaging constraints. you'd be able to make plenty of power, and it wouldn't be hard to do an external wastegate setup...

cry kit is w/o a doubt a deleteable part of the setup

the wing comment shows your ignorance.


Go back to your room and think up something more intelligent to say.

Fact is, your car = the slower compared to that car w/ the kit on there.

Like spy said, for the amount of boost he's probably running the internal wastegate is just fine and makes the packaging much easier. I don't really like the way that kit is laid out though. The turbo is farther away from the engine than it needs to be, and using stock manifold is a cheap*** way to do it. Considering their comments about the flow of the stockers and the differences between the 3400/3100 manifolds, I'd say these guys either have no idea what they're talking about, or they simply didn't want to take the time or money to make it better.

yes an internal wastegate will probably work fine for him, but if you are looking to push some decent psi an external wastegate is the way to go

ok, how does the wing show my ignorance? I don't like wings other than stock ones, i think it is ugly, that's my opinion....

and yeah my car is slower than his for now....oh well.......all of us working on performance were slower at one point, my car was faster than yours before you turboed it, big deal, once my turbo is on my car i will be faster than his, it takes time and money though.......

and if you wanna bust on me again, go right ahead, i don't really care.....

i'm not gonna jump and start busting on other people for no reason......

he posted a link, i looked at the setup and i made my comments, it's my opinion...

[tejohnson]

I would be curious too see how much it costs...

[ganut]

I don't know..... it seems that the air flowing accross my intercooler is pretty hot air to begin with (100*+ temperatures here plus radiant heat from the pavement) so cooling that air down by a significant amount may prove worthwhile......... I'm not gonna say I know this for sure, but it sure seems like it.

ahhh skeet skeet skeet

[SofaKingLoud]

turbo you can do much more with a turbo and its cheaper

[GA SE/T]

The guy to talk to about this kit is Bob @ EPP. They are a vendor on LS1tech.com. I'm sorry guys, I don't have a whole lot of info about this kit/GA and how exactly they are doing their tuning but I thought it would spark some interest.

[2002GT]

is that a carbon fiber sc/t hood in the last pic?

[tejohnson]

Turbo

But I am slightly biased...

[tejohnson]

I don't believe there are any definitive numbers at this point. They do have a forum, perhaps that may be a good place to raise the question. I can say that it would be to the point where you would be concerned with the transmission holding up.

[Germ]

the level 2 kit is a 5psi and inercooled kit.

you should be around 250 wheel HP with that kit

as long as you dont drive like an idiot all the time, the tranny should be able to sustain the power for awhile. look at me, i am runnin 10+ psi most of the time and i have a stock 4t60e, so i would think the 4t4x's should be able to handle 5 for a while.

[bu01]

but you can adjust the boost up on the stage 2 kit.

[Germ]

well, you could, but you would need bigger injectors. thats why its limited to 5'ish psi

anything over that is a chance YOUR taking and we dont recomend unless you get larger injectors.

i am sure you could go higher, but i wouldnt even chance it.

the level 3 kit is the one that includes injectors to go up to around 15 psi but we recomend 12 on that setup (max)


anything over 12psi, i would consider looking into a high flow fuel pump from Walbro to help get the fuel there better.

i am running a Walbro 255 LPH and 42.5# injectors and i have PLENTY of room to go MUCH higher than i will ever need with these injectors and fuel pump.
