Turbotech V's Turbosmart

[Get EPIC]

Hi guys.I currently have a turbosmart boost T ,one of the latest type with the ball and spring and was just wondering if a turbotech would be any better? I will be getting a retune soon with bigger injectors and z32 afm to go with my current turbo which is a apexi ax53b70p25.The common trend with these internal wastegate turbos is that they tend to drop a few pounds of boost towards redline. Cheers

turbotech ones are better and cheaper. but if the turbosmart is working fine its up to you if its worth changing or not

there is a thread on here some where thats like 70 hundred pages long about the turbotech boost controller being the best so i brought one in short it was shit. i now have a turbosmart T and think it is heaps better.

I'd say that will come down to installation issues.

The turbotech simply be design, is better.

Turbo tech, when i was 18 and first got my 33, did heaps of research, got my self a Turbo Tech , it was the best thing i ever did! holds boots good on stock turbos

I had a better boost curve running the Turbosmart than the blitz ebc I upgraded to, although the ebc does ramp on the boost a little quicker.

Either of these cheap manual regulator style controllers should do the job perfectly. If your boost curve still drops off it wont be the controller, more likely you would need a stronger wastegate actuator.

+1 to turbotech!

Had a GFB bleed installed set to 12psi,

then switched to a turbotech (just to test) and the car hit 12psi so much quicker then the GFB, ditched the GFB immediately.

turbotech will be my only manual bleed valve choice, other then that, EBC it is

Thanks for the replies guys. I think i will look into getting a stronger actuator to suit my turbo.Does anybody know if a hks or garrett actuator will fit my apexi turbo?The actuator on it is apparently a 12psi.Cheers.

if you are having problems with boost up high get a stronger spring, be easier to control and will require less air to be bleed and hence work better.

better investment imo

Buy an EBC. The cheapness of skyline owners never ceases to amaze me. It is scrooge season though I suppose.

So do you believe an EBC will stop my boost dropping at high Rpm,cause if so that is all i'm looking for?

A decent electronic boost controller is always going to be better then a bleed valve if set up right.

Just Jap have the Blitz Dual SBC Spec R boost conrollers going for $599. Its not cheap but you will get great results....

here is my boost graph its holding 22psi with a 15psi actuator.

[JonnoHR31]

you have a .2psi spike in the middle there, no good. seriously tho thats a nice graph

if your on the cheaper side and want a decent ebc profec b II is a good ebc when set up properly

The actuator is doing most of the work in your setup, try that with a 7psi spring. I have the same Blitz unit, it wont hold boost any better than the Turbosmart as my actuator is blowing open.

The Turbosmart and Turbotech ones are not bleed valves, they are regulators that are run in line, just like an ebc. They are great if hooked up correctly, not just for tight arses.

Buy an eBoost Street for < $500 and you'll be right. Bleed valves suck the fat one.

not if the spring is not strong enough and the gate is blowing open.

There's more to EBC's than just a flat boost curve.

[Munkyb0y]

and a turbotech is not a bleed valve. it's a ball and spring type that blocks the pressure to the actuator until desired boost is reached, at which point the pressure is passed through.

very simple. very effective. very cheap.

but it only holds one boost level throughout the rpm range, and isnt configurable in any other parameters, obviously.

so depending what you need. ebc may be better, or may be a waste of money.

I know I have one, but they aren't magic.

yeah,e-boost street is what i was looking at actually.So i think i'll go for that.Cheers.
