Any suggestions on a boost controller for Legacy GT-B?

[Guest]

Ok... Im now looking to buy a boost controller for my 2000 GT-B. And I wanted to check with you all to see if you have any suggestions.

I have no idea on which boost controller to buy and which one's reliable and yet affordable.

Below are a few trademe links of boost controllers I had a browse of.

Any comments greatly appreciated! Thanks!

Apexi AVC-r or Grready Profec Spec B are about the only ones suited to the twin turbo low/high boost curve

ie RPM based boost settings which means the ability to set boost up till about 4500rpm at a safe 12 psi? and raise it to 16 from then on'ish

AVC-rs are brilliant. i had one in my rex. Heapsa options but they can get a bit pricey. look for one second hand.

If your wanting something a bit simpler, the Gizmo IBC isnt too bad. Again probably best to be buying second hand.

I just looked at those boost tap style controllers you were looking at. I don't think they're the one.

I have a Grredy Profec B SpecII and am really happy with it.

The main benefit of an in cabin EBC is the ability to fine tune your boost control. I found it took a lot of

tweaking to find a setting I'm happy with and I still tweak more than I thought I would.

The boost I get seems to vary a lot with air temperature so I change the setting if I'm doing a long night

drive or day in the sun.

The Greddy isn't rpm based however if you look at another of my posts you can see dyno sheets showing

boost curves and they look pretty safe. http://www.clubsub.org.nz/forum/index.php?topic=160.msg43657#msg43657

At a standard setting I'm on 14.9 and 16.8psi and gives I'd guess 15kw of the 20kw I've got over stock.

This controller has been my best bang for buck mod so far.

I'll post my controller settings on that dyno sheet post this evening.

Hey thanks for that. Really appreciate it.

Well I have decided to get the Grredy profec SPEC B boost controller. My standard boost is between 1 and 1.15 bar(roughly 14 - 16.7 psi) SO hopefully this improve boost when and if I need it. ;D

plus 100 on that... or one of these first, maybe.. Zero Sports Sequential Controller but the Apexi AVC-r works well.

you could just disconect it and let it free boost go on you know you want to!
