forget the term boost jet and call it what it actually is. A "Restrictor"

its a small piece of steel tube that is fittted snuggly inside the actuator supply line from the manifold.

it has a smaller hole in the middle approx 2.5 - 3mm compared to the 6mm rubber line.

im running one in conjunction with my PFCBC and a 18psi actuator and i have no issues controlling boost up to 27psi.

ramps onto boost hard, and then stays within 1psi to redline.

and just to clarify an earlier remark in regards to increasing boost can make it come on sooner.

if your target level is close or just past your actuator tension, then your internal gate flap will allready be opening before you reach your target boost as to control the clime in pressure. If you were to run a heavier actuator and run higher boost then the flap will stay completely shut for longer causing it to ramp up harder and earlier.

not 1000rpm sooner but certainly 100 - 300rpm sooner.

What I do is I start with a brass t piece. Solder the third leg closed. Then I use my micro drill bits used for drilling electronics like printed circuit boards. I just start drilling bigger until I get the right boost. Either that, or start big and solder it and go smaller.

soldering the brass is very easy. that way you don't have to keep buying nozels.

the t piece costs like $2.

It works without an aftermarket ecu. Just get rid of the stock solenoid.

Either that, or get a jaycar iebc and use it to control the solenoid (and use a restrictor to control the boost level).

The jaycar iebc will allow you to have the quickest possible boost build and best control over the boost curve compared to any ebc out there.

my gtr runs a Tee'd off little peice of silicone hose with a utilux bullet head clamped inside with a hole in the end. 13 psi.

Now thats a cheap ass controller!

"Clamped" Huh

look like zip ties to me.

back yard racing FTW.. lol

mine is an internal restricor inside the feed line. i dont have a T peice.

    • So, what did you decide? If these items were going in and out of stock, you could at least order the two in-stock pieces. Also, I'd say the stock bit of airbox isn't that restrictive to your NA motor. To test if it is, fit a vacuum gauge between the airbox and throttle body. At WOT do you measure any vacuum?
    • Hey guys I have a 2001 Nissan stagea vq25det, I don't have any engine lights and not really any issues running but I was curious to see if I could use my obd II scanner to find anything that was hidden and I plugged my scanner in and it just said "Low voltage cannot scan" does anyone know how to fix this or what this could be?
    • Sadly we have something in common, our Skyline's like blowing up electrically 😢
    • So, no videos, but, the FAB9 Elite manifold and 68mm Bosch throttle bodies are in stock, but, not the rear part of the air box The FAB9 rear airbox thingie is made with a 3" intake pipe, to suit the 3" intake pipe size of a 68mm throttle body  When they get some more in stock is currently unknown as I'm waiting for FAB9 to reply with a ETA on resupply, my assumption is they outsource their plastic printing stuff to "china", and with the current "tariff war" going on in 'Merica it could be on hold for an undisclosed time Should I pull the pin on the Intake and throttle body, and wait for the airbox?????, that's what I'm thinking... 1. Would the standard 2.75" OEM intake on the air box really be that much of a restriction compared to the 3" naturally aspirated?????? 2. If I don't get the 3" FAB9 airbox fitted at the same time as the intake and throttle body will it need a retune, when/if it eventually turns up?????? As I'm impulsive, to a fault, decisions will be made within....."what's the time now"???....let's say 12 hours......LOL
