Why won't the E05 turbo fit a B5?

**Rieger_RS4** · 08-08-2004 11:27 PM

It only fits the B6 A4s, but isn't the engine the same as in the B5? Why won't it work then?

the issue is not fitment. the E-05 is simply a modified k03 turbo that is not recommended to be run above 18 psi.... currently revo is the only company who makes software for it and the software is only available for B6's... i would not recommend it personally for the price the power is just not there.

damn... what makes it so good that it can't take more than 18psi? Why not just go KO4?

Reminds me the drama in B6 forum. haha, good stuff not to mention eurocode.

**derek2079** · 08-09-2004 02:59 AM

or go with the Garrett GT28RS "Disco Potato" Turbo

look here for best prices and shiot

I'd avoid that turbo, personally. Save up for something better

**EVIL-AUDI** · 08-09-2004 05:17 AM

E05 is simply not worth it. Save for a T28 and laugh at the E05 guys.

They sell the K04-015 for 725 shipped!

i didnt mention eurocode because other than installing the turbos they have nothing to do with them, they are a supplier. the producer of the turbo is eurospec and they will not warranty the turbo if it has run above 18psi. i will say that eurocode does tune their E-05 setups above that boost level. i would too on race gas, if not you wouldnt make any power at all. bottom line go big or go home.

**OverSpun** · 08-09-2004 12:47 PM

eh, personally if they offered it for the B5 i wouldnt pick it up because i like fries with my steak.. (customer service with the product)

I like mashed potatoes.

Those prices at
http://www.ctsturbo.com/turbochargers.php are great. I didn't know about that site before this. www.mjmturbos.com was the only one I saw, and they sell K04s for about $799.

**AudiMan** · 08-09-2004 01:38 PM

i like coke, but yah E05 or even K04 are not really worth the money. I'd rather save for a T28 or something like it. I see a six speed B6 with a GT28RS in my future. Time will tell.

**OverSpun** · 08-09-2004 03:19 PM

for the money, you cant beat a k04. honestly.

Why run that little thing when you can run something like this.
Vid of my boost gauge while making my last run on the dyno for the 1.8t challenge.

**bitterchild** · 08-09-2004 05:22 PM

Please tell me that was a 5th gear pull. Your spool time sucks. Sexy snail though, any topend work to get some overrev?

apparently you have never seen a dyno pull before.

E05 is a midified KO4 not KO3
it doe shave some pretty good power I recently saw one dyno 200 HP and 220 ft/lbs at the wheels
while my car w/ KO3 and chip/exhaust did 164 HP, 183 ft/lbs

I'm not so sure about that. Everything I read indicates the E05 is a modified K03. To my knowledge, the K03, K04, and E05 all share the same body. The main difference in the E05 is the modified wastegate, and has a larger exhaust wheel.

from ecodetuning:

"The E-05 utilizes the compressor wheel and housing from the S model K-03"

yet it can't handle the same amount of boost.

Probably because of the agressive larger blades.

Lon was running 1.3 bar on 100 octane, his turbo no longer has a warranty and its a little more then a week old. the E05 has by no means ever proven to be a stable turbo nor has it ever made really impressive power.... being that it is built from a k03 it would most likely have that signature boost fall off that the k03 has as well not to mention being a huge restriction from the small A/R of the wheel/housing.... if i would have to venture a guess it would be plagued by very high friction temperatures which is bad considering the inner walls of the compressor housing are very very thin.

omfg it supports 1 bar of boost for 1325.00 are you fvcking kidding me? who hit the bong before coming up with that price?

damn you think the B6 forum was bad last week wait until all these turbos grenade and there is a mob of foot soldiers with audi keys in their hands (and blown turbo A4's sitting in the driveway) looking for the guys who install these bombs....

*waits patiently for the rants in the B6 forums to begin*

Yeah, I just don't want it to spread here. KIll it while we are ahead and peopel start debating. JUST SAY NO.

Yes, please fellas, let's not go jumping to conclusions.

**excursion** · 08-10-2004 02:16 AM

'Boost' is no indication of power, it is a result of a number of things and not directly related to power output.

In laymans terms small turbos can seemingly make large boost even though they are at their limit and pushing a lot of hot air. The hotter the air, the more resistance to flow and boost rises while power drops off due to the lower specific oxygen content.

A large turbo can be flowing more air, at acooler temperature but at less pressure giving you far more power than the small turbo did at a high pressure.

Does that make sense?

As for the E05 it sounds like it has the std K03 exhaust housing, I dare say it's good for mid range power but it's still going to have the same resistance to high RPM that the K03 does.

Makes sense to me

.

I think the claim to fame of the E05 is that it produced similar flow to a K04, but with much faster spool up time due to the larger exhaust side wheel.

Whatever the case, I would pass on this product if I was a B6. I don't like being a lab rat for any company when it comes to my daily driver. New products are always dangerous. Most reported problems from chips/mods etc... come a year or so after they're released.

yes but the ability for a turbo to hold a given amount of pressure says something about the quality of construction and the engineering put into the design. though the K03 is small and low power unit, the fact remains that people run them for many many miles at pressure levels in excess of 20 psi, the same can be said for the K04. if they are noting that the turbo should be run at that level that puts a big red flag up for me. not to mention most of the Garrett turbos when tested for air flow are tested at 25 psi. I also know that this turbo only made 197 whp hp at 1.3 bar on race gas, so if you wanna back that number down to the specified 1 bar its not really making much more power than a regular k03 with an X-chip (say 160whp on RACE GAS). all that for whopping 1395 dollars. and yes i totally agree with you on the power fall off in the high range.

Although... the X chip is not for the regular K03, it's for the sport K03.

Back to what I think Excusion was trying to say -- Just because the turbo is not recommended that it's run at above 1 bar does not in itself mean the turbo is inferior. The issue is that the E05 is still a K03, with a bigger exhaust wheel, and more aggressive blade pitch. But it still has that wobbly shaft which can't handle high rpms. (at least that's what I gathered from the description of the E05)

Regardless, running a standard K03 at 20psi is silly, IMO. You're not making any more power, and just decreasing the life of your turbo.

Audi2 is running a gt35r/40 IIRC so it doesnt spool until around 5000rpm and peaks out somewhere around 6000rpm. It's a monster (500hp) but it does need some time to spool. cheers! mike
