ProjectLambda: I give them credit + they know legacies in and out, they have helped to bring my built to live for BE5-RevA: 1. Water-meth injection tune. 2. Safe (Hose 10 mod) 3. 2-step launch control. 4. Extending speed limit to 260kph 5. VF26/VF27 mapping for 1.4 bars - VF26 is another breed of Turbo, I think no IHI series for Legacy beats it. 6. Decel pops 7. etc

Hi, A_J_T By the way, I solved the issue. Actually, the metal pipe with hose 10 (bleed/recirc for the ECV duty solenoid (coming from BBOD)) should not be blocked but instead it should be the one going straight to the Pre-turbo intake then the hose 10 from behind the battery (bleed/recirc from the primary boost solenoid) should Tee on it. I think that is the secret and now my primary turbo is boosting at 0.8bar and secondary turbo is boosting at 1.1bar. With upgraded fuel pump to Walbro 340 LPH, now am planning to install water-methanol injection kit with AEM X-Series UEGO 30-0300 wideband 4.9LSU next week then dyno-tune with ECUTek in order to achieve 1.3 bar = 18.9 PSI safely (Project Car (pics attached)).

Hey, Buddy Thanks a lot for the reply. By the way, see below diagram: The part confusing me is how to handle the line 10 which runs as per green line drawn herein. It runs from manifold to BBoD then from BBoD, it terminates on a metal line (bleed/recirc for the ECV duty solenoid (coming from BBOD)) which then get connected to the line 10 coming from behind the battery (bleed/recirc from the primary boost solenoid (coming from behind battery)) through a T piece (yellow encircle) and finally terminates to the pre-turbo intake. Should I do below three steps ? ========================== 1. Run a straight hose from BOV to intake manifold (block first T piece). 2. Connect bleed/recirc from the primary boost solenoid (coming from behind battery) directly to pre-turbo intake. 2. Block the line for bleed/recirc for the ECV duty solenoid (coming from BBOD) ?

Hello guys, I read all about Hose 10 Mod threads on Legacy Twin Turbo and I 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?
