Hmm that's very confusing then as it would appear after reading through all 10 pages in this thread that people with Rev D have done it...

 

Well, the thing is that you're changing of the hoses on the revisions A/B/C to match what Rev. D should be. 

 

So if you're changing something on the Rev. D, then something ain't right haha. 

Also, since Rev. D is reflashable, just take it to SAS and get a tune  Safer and better than doing a mod to bring boost pressure up haha

Hi!

 

i did the Hose 10

mod in a BE5 D 2001/12 with re-written ECU BOV Center pipe and Back pipe changed, i was running almost the same as without the mod with the difference of when hitting 4.000+ rpm the engine started to knock, so I reverted it again. But no idea why it was knocking too much boost? Vacuum leak?

 

i live in Japan and petrol is 96 to 100 Ron so I wouldn’t  say it was caused by low quality petrol, and after i reverted it works totally fine solid boost all range and knocking is gone! 

 

Shall i try the Hose #1 mod? 

 

Cheers from Japan!

Hiya! 

 

The Hose 10 mod only works on earlier gen legacys. The reason being, is because the hose 10 mod, actually brings the cars in line with how the revision D is setup

Hello guys,

I read all the threads line by line and was eager to implement the hose 10 mod on my 1999 GF-BE5 (BE5A48T). So, I did exactly that. What I noticed:

1. Boost is good at lower rev range and it was really fun, however, I only got 0.4bar = 8psi on primary.

2. But boost tend to drop soft at higher rev range, looks like secondary Turbo not kicking after the mode.

 

I noticed, there is also another T piece (as encircled red in attached image) connecting three lines: hose 10 that goes into a metal piece (encircled yellow) and another hose 10 which comes from behind the battery side and then to third hose that comes from Turbo intake beneath as shown.

The blue hose is the one I have disconnected and blocked from first T between BOV and intake Manifold then ran straight grey hose as highlighted green.

().

 

How do we handle the second T piece? Could it be the one making me not achieve the best end result?

So the atmosphere no.10 hose and the no.10 hose from bbod line both t off and go into inlet. so do you leave that little t section in place and run both atnosphrre line and bbod into t piece. Because you cant just run bbod no.10 line straight to inlet as that would expose atmosphere line that comes from guard?

mine is a 1997 bh5 automatic, can this be done ? the  BOV has 2 lines out of it ?

[Joker]

I have never meddled with this sort of thing but that is not a 1997 car : 98 maybe?

 

eg 98 was the change over year in May

I was messing around with this the other day and found out something interesting.

 

If you swap lines 5 & 6 (if I remember correctly)

And then do the hose 10 mod.

 

You will see the turbos boost up to 23-24 psi, it did not trigger error 66 either.

 

Obviously running this high boost on a stock engine is tempting fate, but it did absolutely rip

 

This was on my rev a gtb

Thanks for this. I read through this and a few other related threads. It sure sounded complicated!

 

I removed the hoses, capped the one T top way back and in with a 1/4" vacuum cap and a black Zip Tie, and used a single hose to replace the one on the top. Did I fail at any of that? Took 2 minutes. Car seemed to drive just fine. i'm not sure if I noticed any difference on my B-version car though.

I read a lot about the hose 1 mod and .8mm restrictor (which I ordered for $6) but it isn't clear to me where it goes, inside of the BBOD, which I need to get in to check/clean anyway, or on the same hose outside of it. Any help/pics would be great, as it will be here on Tuesday. 

 

Have there been any negatives to either of these mods now that some time has passed for you guys? 

 

Again, thanks.
