Hi Guys

I am currently converting my Spi to a carb turbo setup and I just wanted to find out on the Inlet manifold there is a banjo and screw type nipple fitting I know Ive seen people use the nipple to go into a dump valve on the Plenum via a silicon tube


By battleroc at 2012-09-03


As my mini was originally an Spi, so has the Servo brake cylinder will the other pipe that comes out of the inlet manifold with the banjo be used as the vacum to brake servo?

Or do I need a 1 way valve ftting?

Use the banjo on the turbo manifold. If you unscrew that valve from the bolt, the thread is 1/8bsp so perfect for a barbed fitting for your boost gauge etc

I hear you on the valve bolt for boost gauge

are you saying plum the servo though the banjo because i ithought i need a 1 way valve as if i come on boost i will have no brakes?

Your existing servo hose should have a one way valve in it (round thing part way down the hose). Just fit your existing banjo onto the turbo manifold.

What Andy said, you can also junk the ugly looking valve and use a 90 deg fuel fitting or similar as they are the same thread.

If I were to do it all again, Id start with an SPi, fuel tank, fuel lines and fuel pumps already there for you.

Ahhh

Ah, that's interesting Brett.

It was always a concern for me as I was about to build a turbo spi till recently.

it has alot to do with the cam good news for us though turbo cams dont have alot of valve overlap...but i found whilst on the machine set fueling to be a tad lean (15:1) 25-30 deg advance 1200 rpm idle 90degC water temp and the emissions dropped to almost nothing

Yes i moved to the darkside *happy*

But if you use a carb engine in a spi car you wont have the spi emissions test anyway :)
