Advice: Boost controller
 

I have a '94 S14 SR20DET, Zenki model.

I'm completing a stage 1 managed by a MINE'S control unit that allows me to raise the turbo pressure through a boost controller.

this is a temporary solution because subsequently I have to mount the following components to get to a stage 1.5: PowerFc + integrated boost controller + solenoide valve + PowerFc controller + nismo 555 + z32 flow meter and other components...

I would like to buy a boost controller now, for stage 1 set up:
I am undecided between the following 2
-GFB (Go Fast Bits) G-Force III Electronic Boost Controller
-GREDDY profec B Spec II

Do you have any advice?
do you recommend other boost controllers?

THANK YOU

Where are you getting these "stage requirements" from? There's no such thing.


I'd recommend either something from AEM or Innovate.

directly from Mine's

So the Mine's ecu can't control the boost pressure with the factory boost solenoid?

no... it can't

Go on the website for the parts distributor of your choice, find their boost controllers, choose the one that you think looks the coolest. They all work.

I bought a AEM 30-4350 for my setup. Nice looking gauge comes with all the goodies.

^^^ AEM Tru Boost +1

Innovate SCG-1 is also nice - includes WB AFR and failsafe features - very compact for a lot of functions:

ive had the AEM tru boost and the Greddy Profec b spec II and i gotta say, i love the greddy one better. idk if its my settings or not, but Tru boost doesn't seem to have a boost reduction setting incase of over boost, The greddy one does.

I only got a truboost after my greddy one stopped sending signal to the solenoid. Apparently it has happened to a lot of people.
