Z20LET Vacuum lines HELP!

[zmayich]

I WANT TO USE ONLY FRONT BSC, AND ONLY AFTERMARKET BLOW so I DESIGNED A DIAGRAM LIKE THIS:


SO TURBO FEED FOR BSC, BSC Connected with Actuator, and the third pipe from BSC should be going back to AIR INTAKE PIPE Before turbo but i connected it (trough V.BOX ) with INLET MANIFOLD line to increase pressure for FPR AND BLOW...IN THIS WAY BSC have enough vacuum, and FPR and BLOW too...

I could put away this vacuum box but i think it's better this way???

IS IT GOING TO WORK??? ANYONE TRIED ONLY FRONT BSC WITHOUT REAR???
Thanks!

I run front BCS only, with a OE DV blanking plate and bailey dv...... All vacc supplys must T off from the FPR vacc. Make sure the FPR is first on the vacc otherwise the car may lean out.

I would remove the vacc box, as IMO its more space for the single vacc to have to suck on..... (if you get that)

Less space to vacuum = faster response

OK, only problem is that I don't have seperate vacuum feed for FPR and for BLOW... Where did you get feed for your Blow???
Can I do it like this: ?


One thing more? I don't have rear BSC, Is that a problem because the connector is now blank? Is it going to make Error or something???

[wkdkris]

Unplugging it altgether will bring the EML on yes

[zmayich]

EML? not so good in english shortcuts (I'm from Bosnia remember )

[wkdkris]

It will display an orange light on the dash, (fault/service/error).

You must have R/BCS plugged in, but un-used

[zmayich]

OK, thanks, very much!

[zmayich]

I finished lines and ordered one more boost solenoid so it's ok now... YOU MAY LOCK THIS THREAD!
Thanks EVERYONE!!!

after Speaking with a mate it's the map that controls boost, best to have them all plugged in and run a better map

[Gsilee91]

Do you have a standard diagram??

[zmayich]

Rear bsc is only on wiring loom because errors...everything else is like on a diagram... Stock map also, 200HP... everything is good

[wkdkris]

Do you have a standard diagram??

Leave the front BCS well alone mate while a standard turbo setup etc anywayz.... The rear one, ditch everything, leaving only the bcs itself plugged in for ecu. Run a T piece off the FPR for a BOV, and a guage. Block everything else.

Hi mate some one has messed with the front bcs and I need to know how to get it back to standard ??

[wkdkris]

Il take a pic of mine n explain if i can lol

[Gsilee91]

Spot on cheers mate

[wkdkris]

there ya go buddy sorry i took so long, top sticky up bit goes to actuator, bit from the side, goes to side of turbo. bit on the back near the connector runs to the back of the engine somewhere
