It's been a little while since I found time to play with my VR2, ever since my gearbox broke (left diff bearing busted). This week I replaced the knackered gearbox with a brand new one (!). Now that I could drive it for the first time in almost 2 months the mod bug bit me immediately. So first thing I wanted to do is install the Perrin boost solenoid I had waiting in the box for months.
Now... that got me a bit confused. The original OEM solenoid has 2 lines connected to it, the Perrin offers 3 available ports and one more at the bottom.
I couldn't find out exactly what and how it needs to be installed.
Then I looked at the original routing of the OEM solenoid and:
1. hose ends up in the intake elbow (with the red tip)
2. hose ends in the big plastic T-join piece for the air routing

So er... how to hook up this Perrin with it's 3 ports (and what about that port at the bottom of the Perrin? In the manual they show different options to select from:
1. internal wastegate
2. external wastegate

I assume this second one is the one to choose.
Okay, then these 3 ports on the Perrin:
1. NC -> Normally Closed
2. COM> Common (to wastegate)
3. NO -> Normally Open
I assume there is a NC situation for VR4, so I connect:
- the original OEM hose nr1 (with the red tip) to this NC port
- the original OEM hose nr2 (to the big t-join piece)
- close port NO with a supplied blank screw
Can anyone confirm my assumptions? Nick Mann possibly?
And what about this 4th port that is not mentioned but is 'open' as far as I see?
Thanks guys!
