i think its a vacuum pressure sensor bullshit thing

 

1. FPR-fuel pressure regulator?
2. blurry picture?
3. oil sensor? a wire is suppose to go there. i know that is where you tap it for an oil feed for a turbo.

if ur talking about the top piece in pic num. 1 its not a FPR, thats the piece at the bottom left of the pic...

1.vacumme(sp?) actuator for secondary butterflies
2. ?
3. oil pressure sender/sensor

 

sorry about the second pic....

ill give a little description...its under the intake mani and its a black box with a sensor plugged into it....

I'll try to get a better pic in the morning...

also, what vacume line hooks up into the thing in pic 1??

 

anybody???

 

#1 is secondary runner actuator
#2 is IAB (this controls #1)
#3 is knock sensor

 

#2 is Intake Air Bypass valve (plastic box) it should have one vacuum line coming
from it hanging around there somewhere...hook that to #1 picture...for # two
you have to run two wires to work that thing...one to the ecu A17 (pink and ...)
and the other is 12volts (yellow with black strip)
#3 is knock sensor...run one wire to you ecu D3

 

[QUOTE

#3 is oil pressure sender.

 

#1 is the actuator for the secondary's in the gsr intake manifold
#2 is where the vacuum lines go for the secondary's on the manifold\
#3 is the oil pressure sendor ( not positive on tech term, but i know green plug goes on there and its a bitch to get on and off

 

do all b series motors...ie b16??

or is this strictly a b18c thing???

lastly, would a rechipped p28 ecu run this b18c???

or do i need to get a p72 ecu???

The correct name for the pic #1 is diaphragm. The #3 pic is your oil sending unit, that’s where you plug in your oil pressure gauge if u have one.

 

if u have a skunk2 manifold then go with the chipped p28, if stock go with the p72

 

the #1 pic is the vaccuum actuator for the secondary butterfly valve system, which is only on the GS-R engine. thay open at higher RPMs for better low-end/high end torque/power. #2 is the IAB that valves vacuum to the actuator, and #3 it the oil pressure sender/sensor. the knock sensor is higher up on the block than that.
