hello guys,im looking some advance about EBC,i found on ebay .will by good ?thanks

That EBC !!! I smell soy sauce somewhat,when it comes to something so critical get a branded unit,ie Greddy,Blitz etc.

I wouldn't go anywhere that. Greddy Profec-B is the best one out there for the Z32. I'd rather have a used Greddy than a new unbranded unknown potential headache.

Greddy Profec-B spec 2 is the one i have and its decent.

My experience - the HKS EVC4 is a reliable "fit and forget" setup.

+1 for the Profec, You can get a new one for under £200 if you keep an eye out.

 

2nd Hand ones seem to go around £100-120 last time I looked (mine is silver and keep debating whether to get a black one to match my interior better, sad I know!!!)

I've worked with most EBCs, and the new GReddy Profec is one that stands out as being the best, and by "best" I mean the most accurate to dial in. It is also the best looking, but that is purely subjective. The Profec B Spec 2 is easy to use and very accurate, as is the e-01 but with a more involved GUI and E-Manage compatibility. All three GReddy models work very well and will give you quick spool and hit a specified boost target consistently when set up correctly.

 

Apexi AVC-R has grown on me a lot in the 8 years since first dialling one in on an S13. They work very well and have more options than the GReddy models, including boost by gear when wired fully into the loom. They are also more expensive than the Profec & Profec B Spec 2.

 

Blitz DSBC is a solid performer, as is the SBC-iD with its separate controller/display.

 

Turbosmart e-boost, I am partial to as I used one on my S13 drag car for a couple of years. Not worked with one since then, so pretty rare.

 

The most convoluted one to use was an early HKS EVC model.

 

The most annoying by far was a Gizzmo model where you have to press two buttons at once to change a setting. A part of me died that day. Mapped a Zed with an MS-IBC fitted the other day, and it was better, but still limited (no vac readout, flakey peak boost readout).

 

The most unreliable I've found to be is the HDi range.

Offer the guy £150 as a buy now and he will most likely accept.

 

I bought one a while back and its genuine and a few members have recently done the same.

 

here is the thread I put up when I bought it.

i got one more question about BLOW OFF,it make sense to install in auto gearbox?

It doesn't make sense to install it on any car

You win a million points sir! :) :bow:

 

Blow off valves are one of the worst things the aftermarket tuning world has been blighted with. Fitting them to an auto is comical, fitting them to manual car is awful.

 

As you can guess, I feckin' HATE the things and I use that word in the very strongest sense.

 

:)

I kinda like mine, if I'm honest.....

I like how mine sound, but don't like the stalling they introduce by dumping metered air.

 

As for boost controllers, I like the greddy e-01 that's tucked into my sun visor, hidden out of sight unless I need to look at it. :-)

 

Any reason why you want an EBC over an MBC?

Any reason he'd want to go for an MBC over and EBC? :confused:

Exactly, just wondering what's the basis of the choice either way. How many of us actually touch the thing once it's set up. Bit like electric seats, you set it up, you leave it alone...

Well you would do as the MBC has limitations. EBC does not.

Thats kinda like saying what's the point in engine management, when a carburettor can also put air and fuel in.

MBC on Jaffa's car. 1.4 bar and 692whp.

MBC on my car. 1.7 bar and 570bhp (fly).

 

Fitted MBCs to 3 Zeds in the last 5 days for mapping on the dyno.

 

BOVs are suitable for many turbocharged cars, ones with short intakes and MAFs (my own modified Impreza for example, running a GFB RFL), any with speed-density engine management. The one car they should never be fitted to is a Z32 with standard intake pipework length/configuration and stock MAF in the stock position.

 

Blow-through MAF means run whatever pressure relief valve(s) you wish upstream :)

Cheers for that Noel. Kinda high lights what I saying, they work.

 

It's not really like comparing engine management to carbs because engine management is far superior. Carbs are a a bit hit and miss. Yes with an MBC you have less controllability but unless you know exactly what to do with it its a bit gimmicky really.

 

I'm not attempting to say that manuals better, not at all. Just that when it costs 10xs more for an item, is the cost benefit ratio there? They both do the same job which is to control boost.

My understanding of one of the key benefits of EBC over MBC was described in the Sport Compact Car Project

300ZX part 2 published in 1998:

 

"The EVC works by monitoring manifold pressure and uses a cycling solenoid to limit the amount of pressure

that the wastegate sees - much like the old bleed valve method. One of the advantages the EVC has over the

old-school bleed valves is that the sophisticated microprocessor will not allow pressure from the intake manifold

to reach the wastegate until the set pressure has been reached. Once the set pressure is reached the EVC

commands the soleniod to open, allowing manifold pressure to reach the wastegate. This keeps the wastegate

shut until the last possible moment. If a bleed valve has been used to fool the wastegate, pressure would build

up, causing the wastegate to slowly open. This gradual opening of the wastegate valve causes soggy boost

response and reduced acceleration."

 

The article refers to bleed valves rather than MBCs, but the principle point remains the same?

MBCs "crack" open at a specified pressure, they don't "bleed" air in order to increase boost pressure by diverting pressure away from the actuator diaphragms. They are basically a mechanical solenoid.

 

With correctly specified springs, they work exactly the same as an EBC by not allowing the actuators to see any air until the set pressure is attained. They are, of course, lacking any sort of PID feedback :D

hi,i'm looking any advice how to install EBC profec b-spec II

thanks for any healp

Follow the instructions in the manual or online as a basic guide. Keep vac lines as short as possible, and equal lengths to each actuator from a t-piece you will likely need to buy. Use proper silicon blanks or small lengths of hose with bolts :cowboy:

 

The OEM Z32 ECU maps (all territories) have an inherent fault where the built-in fuel cut is programmed so high as to never actually be reached on stock turbos/injectors/fuel pressure. This means you can, and will, damage your engine if you run too much boost (don't rely on the knock sensor).

hi I found a tube running from the turbines to major mainfolds in both sides.it seems that there already was EBC.
