Boost Controllers

[BZG Wagon]

Is one type better than the other? I've read a couple posts saying the second type is less reliable & more prone to spikes.

Any experiences with either (or recommendations of another type)?

Turbosmart > China

The GFB ones are pretty good and I didnt notice any spiking using one on the skyline when I had that

Ummm the 2nd type I used on my gt4 and it would spike and blow vac lines etc

Was really hard to get stable boost so sometimes it would run 12psi and then just start going to 16psi

[BZG Wagon]

Huge price difference though; $25 vs. $110 (hence asking). But blowing a vac line is pretty intense and a wast of $25 (won't be going that route at least).

Looks like there are immitation(or unbranded?) turbosmart valves on Trademe for $45. Hmm... do I risk it?

if you get the GFB ones on special you can get them for around the $75 mark

Do it once do it right

2nd hand Profec B!!

Mine cost about $120 and is awesome - 3 dials - Old model

Agree, did some research on this a month ago but decided that the wastegate limited 12psi is enough for my old engine.

Was going to get GFB - the extra 50-100 could save you thousands.

used the turbosmart one myself, big price difference, but that's usually a good indication of quality, eh.

held boost well till I ran the bottom end

Try this and call it a day it blows those Turbosmart valves into the weeds.

I have a Turbosmart dual stage boost controller. Had it 5 years, never had any issues with it. No spikes and holds boost well. Love having the ability to just flick a switch to change boost settings.

This! Electronic is worth it. Was getting spike with my manual turbosmart, no problems since going gizmo ebc once it got tuned.

I should add it's for my 1993 2.7L Diesel Nissan Terrano to help get up the dunes.

It only puts out 79kw @ 10psi and not exactly a speed machine so I'm tyring to do it somewhat on the cheap. If it were my other car I'd be throwing wheelbarrows of cash at it.

I'll sleep on it - either the GFB, Turbosmart or Turbosmart copy (electronic seems like overkill / too much effort on my low performance vehicle ).

I'm using the Turbosmart Boost Tee, way more reliable than the Racepro manual boost controller, doesn't spike like the Racepro did, and alot more finer adjustment. Would definatly recomend the Turbosmart over any other cheap brand.

If you want a tap go with the turbosmart.

if you want an electronic go with turbosmart.

Moral of the story, turbosmart = win

[BZG Wagon]

Bowed to pressure and got the Turbosmart...

Need to install the boost gauge first - any recomendations on where to plumb it? I was thinking of one of the following three areas:
1 & 2: Drill a hole throught the pipe and insert a join.
3: Plumb it off an existing line (although I do not know what it is used for? Suspect it could be a fuel vac or EGR vac?

Electronic not always win.

In some cases the manual boost tap setups are very good.

How ever we do sell the HDi Electronic controllers which are VERY easy to use and install. Prob one of the easiest electronic controllers to setup on the market.

Electronic not always win.

I've never encountered a situation where they are any worse than a manual one though, and are typically substantially better.

[Al]

^ Pretty much.

My Blitz DSBC was awesome. LCD display, peak boost reading, audible overboost warning and flashing red screen for when you lose a hose Four different boost settings. Got it second hand for $150 and sold it for the same money.

Why even bother with a new manual controller?

[Bazda]

I use a tap on my externals. Can adjust boost in 1s. So simple and so effective. Only works on externals though.

I had an electronic one and it was a pain to setup duty cycle etc etc to get it right. Had to do it on the dyno as on the road id be going near 200kph to get it done as there isnt any traction. Then I could only set up points. What if I want to use something in between. That was REALLY annoying.
The self learn functions always over boosted on my setup and could never set it self right.

Have seen guys have settings on theirs at say 15 psi 20psi then 30psi.
Then they cant get traction on 30psi at the drags, 20psi too low but they cant tune the 25psi because they need to go onto the motor way to do so. And you need 5 runs at the minimum to set it nicely.

My tap always brought on boost faster than any of my electronic ones could. And held it Rock stable.

Just turn my little tap a little and done. Out at the race track its super handy I can set boost say 15, or 16, 17 18 etc in just a small turn of the knob.
Rather than playing with my electronic controller lap after lap. :S

I used GFB atomic on my old MR2. Reliable as, held steady 18 psi, no issues.
