Another exhaust manifold option for stock setups.

[n7plus1]

If you are talking about the black b6 I am building, then hey, i can only go as far as the money i am given will allow.

rich was stupid in throwing all of that money into it...shouldve bought a b8.....

there is a plethora of used BEX manifolds. wonder if they ship to the states?

I contacted them and will know a shipping rate by Monday. Pretty good deal on the part...as long as the shipping isn't too expensive. Those are all pretty low mileage cars. Lots of Avant's in Sweden apparently! My kind of place...

[Bische]

Let me know if you guys need any help with translation, i would be happy to help

[boy412]

Thanks Bische! I have a pretty decent translating "widget" on my Mac...good enough for basic communication anyway. But I'll let you know if I get stuck.

PS - Let me know if you see anyone over there selling a turbo from a BEX motor.

[Don Supreme]

Sort of an unrelated question, but how do you get access to ETKA ? i'd love to be able to look up part numbers and diagrams.

Timing on a N/A motor and a high boost turbo motor are not even in the same zip code.

k03s? just look up the part number and search on the first page, im sure theres plenty of them on there. But it would probably run you x2 the price of a k04 however

[EErie B6]

so whos testing?

I have been running one with a FT. What do you wanna know?

Highest EGT i have seen is 865*C and that was on the second of two 3rd gear pulls back to back.

[widgget]

^^ and comparisons stock vs the BEX one?

don't know if i would sacrifice spool for more top on my GTRS at this point since i rarely do any highway driving.

[EErie B6]

Logs or Pics?

I don't have logs cause I never bothered to log my 1+. Pics didnt happen cause I forgot at the time. I'll get some pics of my stock one from the same angles with measurements so people can see.

Are you running the stock one right now Widgget?

[widgget]

yeah, never changed out my mani.

did you replace just the manifold or did you do other things while you were in there?

really looking for log comparisons of a stock mani vs the BEX one (ideally on a GTRS) but since you didn't log next best thing would be what difference did you notice in spool times?

[EErie B6]

No, I went from a 1+ tune on a stock turbo to a Uni630 tune on a FrankenTurbo. Lmao, I think I hit 20psi at just before 2600rpm in 3rd (in the summer heat). And that's faster than my 1+ used to. Evidently I had a leak somewhere.

(read my first fucking comment, idiot) you have issues dude. you need to pull your head out of your ass. i dont give 2 fucks what setup you go with, bc youll change your mind and annoy everyone on the forum with your 16 different decisions before anything touches your car. if you are talking about the b6 not running, then read my thread its not my car and i can only go as far as the $$ the owner has.. which hes been broke for like 8 months. Its not any of your business but if you wanna comment on something that doesnt pertain to you.

Waaa wa weee waaa, I guess teh interwebz iz serius bizness. As for the F4L being a glorified K04, I'd have to say that's a bit of a misconception. While I've never had a F4L, I've ran a K04-015, a very similar (to the F4L) hybrid K04 and then a GTRS. So I've experienced them all first hand in the same car. All in all my hybrid K04 was a good little turbo. The only reason I went with the GTRS is because I had an EGT issue from a misfire that cooked the turbine. That said, that little hybrid on a FWD tip transmission ran neck and neck with a 6 speed stage 1 S4.

Anyhoo, Black99.5 I'm not aiming the turbo commentary at you per-se. I just figured that having been one of the few that have actually experienced all three K04 and GTRS setups, that I'd weigh in on the matter.

Good luck with the exhaust manifold options Eerie.

[boy412]

@Zimbu - What hybrid did you have?

[ZimbutheMonkey]

It used the 32 lb/min 2280 compressor and compressor housing from a Mazdaspeed 3 and a larger turbine with a 15 degree clip. It retained the K04-015 turbine housing though. I don't know exactly what the turbine was from though. It was bigger than the K04-02X one. However it didn't match any K04 specs that I know of. Here's a video clip of it while I was still running my tip transmission. It was reasonably quick despite being at 3500 ft with and running 10.5-10.8 :1 A/F ratios at the time http://www.youtube.com/watch?v=3DqgHmyTiec

[Dan[FN]6262]

Pics didnt happen cause I forgot at the time.

because it was hot as a mother ****** that day. and I already had it installed when we remembered LOL

but the BEX is definitely larger than the stock manifold. the runners are larger in diameter, but the collector appeared to be essentially the same size, maybe just barely larger.

Dang...

[ZimbutheMonkey]

Good dang or bad dang?

[Doug@FrankenTurbo]

Mmmm. I had the good fortune to watch that clip while wearing headphones. That car sounds really good. Have you gone and torn all that out with your big ole turbo, T? I hope not...

[ZimbutheMonkey]

That's with the 2.5in exhaust, techtonics cat and Magnaflow muffler. Unfortunately I had to ditch it when I went to my 3 in setup on my elim. It was actually really nice. Quiet at cruise but it made a nice exhaust note under full throttle. Oh well, I guess that's the price to be payed for more power.

[boy412]

Good dang or bad dang?

Good dang. Roll your own K04 hybrid! Pretty interesting choices...

[boy412]

http://www.bildelsbasen.se/?link=lis...ry=06B253033AH

I cant tell what language, what currency, or whether they ship to USA...or even if its a good deal.

I heard back from them today. Shipping a manifold to the US is 600 SEK...or about $93. This is also excluding VAT, so not sure how much that would add. Not a bad deal for a low mileage BEX manifold...

[boy412]

k03s? just look up the part number and search on the first page, im sure theres plenty of them on there. But it would probably run you x2 the price of a k04 however

The K03s is the KKK03-029. The turbo on the BEX motor is a KKK03-73. Slightly different size compressor:

K03-029 (K03s)
Compressor Size: 36/50mm
Turbine Size: 40/45mm

K03-073
Compressor Size: 38/51mm
Turbine Size: 40/45mm

If I can't find a good deal on a used one I'd certainly just cut to the chase and pick up a K04 or FT.

[audinuts]

bump from the dead... any update on this one?

[davkav]

I actually have my BEX manifold off of my car now so I will take some measurements of the ports tomorrow and post them up.

[FoRbAnNa]

davkav, any updates on the measurements?

[davkav]

Finally received my calipers in the post yesterday so apologies for the delay in posting pictures and measurements.

I would take the measurements to the nearest millimetre as the calipers I bought is pretty cheap. Ill have to fork out and get myself a better one.

BEX Manifold:



I took measurements of #1 runner as well.



Diameter of Collector


Diameter of the runners

[Turbo_Whip]

Does anyone have the comparative measurements/pics of the AMB and the BEX exhaust manifold?

[EErie B6]

Does anyone have the comparative measurements/pics of the AMB/AEB exhaust manifold?

They are the same p/n.

[Turbo_Whip]

They are the same p/n.

According to ECS, the part number for the AMB is 058253033E and the part number for the BEX is 06B253033AH.

For reference, information from ETKA:

[EErie B6]

Shit. Read your statement wrong. I somehow read it as amb vs aeb.

Amb aeb is the same the bex is different. I have a bex on mine and it is indeed a little larger ...but nothing crazy. I didnt think to get pics of it when i had them both in hand.

Did you need to get a different exhaust manifold gasket or do any porting to make the manifold line up...or was it a straight bolt-on?

Same gaskets, no porting needed.

[RLB6]

Hate to be the bearer of bad news and deflation of hopes..BUT........

stock AMB exhaust manifold:


...collector:


.....and runner:

[613B6]

Lol porting the stocker it is!

[Turbo_Whip]

F*#K,I was hoping the BEX manifold was bigger :(
Thanks for sharing your findings, you saved me wasting some money at least!

Anyone know where I can get the stock manifold ported and polished?

[RLB6]

No problem. This thread had been going on so long and it was hard to believe that no one had a stock AMB/AEB mani or time on hand to take measurements.

Finally, someone with a bright idea and a set of calipers. Bummer, but at least we know.

Besides the internal size and shape of the port runners, the only other reason for a different part number for the BEX manifold, compared to the AMB PN, is if the BEX is cast with a better higher temp rated alloy to withstand the higher exhaust gas temps of the BEX setup, to resist cracking better, and have increased high temp operating strength. For tuned setups, expecially if ported, the BEX manifold still has advantages over the AMB manifold.
