What Size Boost Jets Do I Need To Run

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.

we tried it on my uncles 300z last year. but it only works with an aftermarket ecu

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.

T peices are the latest technology. As used by NASA even!
