Hey,

 

Can anyone tell me, or even better, show me with a pic, where the clutch booster vacuum pipe connects to on the plenum?

 

I'm using an NA engine in a turbo shell, and utilising the original clutch booster, but I don't know where it should connect to, as I didn't disconnect it having an NA clutch in my NA shell.

 

I'd assume it would connect somewhere near where the brake servo connects...I'm also worried the turbo plenum is different and I don't have the required connection...

 

Cheers!

...almost by accident really, but it appears to connect a vacuum canister, which I hope I still have, lol. I couldn't have sworn that it had one of those metal hex intake bolts on it...

 

I remember someone telling me I didn't need to use the canisters, and I can install some kind of one-way valve and use the brake vacuum pipes. I think for now I'll stick with the original plumbing, I don't want to make too many alterations until I have everything up and running.

The turbo manual balance bar has an extra take off for the clutch vacuum, therefore you wont find it on a na engine.

 

Simplest way is to T piece of the brake feed, make sure as a minimum you fit a one way valve after the t piece, or a clutch booster failure also kills your brakes

Thanks!

 

Could I also replace my NA balance bar with a manual turbo one?

 

I assume the extra 'take off' is the bit at the back of the bar -

 

The turbo bar has extra take offs for turbo things, which you would need to cap off

 

It's the curved one at the left hand end of your picture for the clutch

I see, I thought that might be the case.

 

Looks like a T and a non-return value it is then!

 

Wish I'd remembered to measure the pipe diameter today...

 

id be happy to do a swap with you on balance bars.

 

im doing a minimalist thing in the engine bay so one less connection the better for me

Like Ianl said though, it also has other turbo type connections, and its and NA engine, so I'd end up causing myself more work plugging up all the other holes...

 

Sorry, looks like I'm sticking with my NA bar, and finding a T and valve.

Hey, went to measure my bore today and came across this, in the booster pipe connections -

 

 

 

 

Do you think it's a non return valve?

That's exactly what it is mate, required to stop back pressure I believe.

Great! Then all I need is a T connector!
