Just saying.
I don't think JFOJ was bashing anyone in particular--how could he? I don't think he knows the guy. In general, we see these small companies come and go all the time. It's just the nature of the business.

As far as BMW AG taking a lesson... I don't think so. MJLavelle could explain this better, but the cost to implement those parts spread over millions of units would drive the cost up substantially.

even at $300, replacing it every 10 years is a bargain.

We're spoiled by cheap parts we get from all our vendors, but when it comes down to it remember you're driving a BMW and not your typical Camry/Corolla/Civic/Toaster.

Pay to play

I Don't consider tighter tolerance, improved design aluminum to be cheap parts by any means. If anything, the reason for my purchase was to upgrade from plastic BECAUSE I drive a BMW

You are correct. BMW stayed with plastic because of manufacturing costs. These DISA units would be over $500 from BMW if they were aluminum. Sure, it would make the car cost "only" $200 more from the factory, but you can't keep nickel and diming your car cost. You have to compromise somewhere otherwise you'll have a $100,000 230hp compact sports car.

You need to get an understanding of how stuff works. Every part of every car (even Ferraris) are a compromise. You can't spec parts made of the very finest material and design for every car otherwise you end up with a $1.2M super car like the Bugatti Veyron with $35,000 tires. Business is competitive and to remain competitive you can't spend all your beans in one area. I'd rather that extra money be spent on interior pieces than some obscure vacuum part that needs replacement (at WORST) every 10 years.

If replacement of a $200-300 part every 10 years is too much for you to handle, this is the wrong car for you. And trust me, you seem to be new to these cars, a $200+ DISA is the least of your worries. The DISA can affect performance but really isn't a crucial part. It won't leave you stranded and won't overheat your engine like a failed cooling system will. I suggest you concentrate your focus elsewhere.

Maybe GAS can offer that one!!

Thought about that as well. But the torque lost at lower RPMs is actually really noticeable. WOT all day long oyster only thing around it

Exactly.
Did I at ANY point say that it should have came on the car originally? You're outfielder ignorance is becoming unbearable. If anything else were to go bad, I would also upgrade to better parts that have been designed in the last ten years. Like drilled same slotted rotors or better you're tires. Improved intakes, water pumps, etc. Is it so hard for you too understand this?

I also intend to test it before I install it. I'll plug it in with the original DISA still in the engine and run it through the RPM range to see how it reacts. From what I've read, this is a two-position valve that changes position at 4200 rpm or so. I want to verify this. I'll post a video of its operation if I can talk my wife into operating the gas pedal while I film it.

All those parts you mention are either downgrades or are unnecessary. You shouldn't come on here and start talking about stuff you don't understand or criticizing parts whose life expectancy are 10+ years. you are just nitpicking over nothing.

How do you know your GAS rebuild kit will withstand the test of time? That's right, you don't.

For someone so critical of the stock part, you seem pretty sure of yourself. Hell, I might even go with the GAS upgrade myself, but I wouldn't for a second criticize the stock part for failing on me (if it ever did)

I'm all for improved parts, but I'm also a reasonable and efficient-minded person.

You're right. Brakes, tires and water pumps are totally unnecessary. You're intolerable.

Glad after all that ignorance, you say that you might use the kit. Incredible...
Hope my review helped

I've considered and used G.A.S. products well before you were even a member on this forum.

Mind your words.

DISA does not exactly work the way you think you will be trying to test it, so do not get to upset or condemn the unit if it does not react the way you expect it to.

The large boxy part of the DISA is a vacuum reservoir, you could try and connect/hold a vacuum hose over the small 1/16" or slightly larger vacuum source port and pull a vacuum and "charge" the reservoir, but it may not be worth the effort.

The way the DISA basically works is the vacuum reservoir is used to store enough vacuum to operate the DISA for some period of time. The solenoid purges the vacuum from the actuator to allow the DISA valve to open under spring pressure and the vacuum reservoir is then used to close the DISA valve again. Or some basic operating principal along that process.

What you really need to do is see if the vacuum hole is similar in size, if the flap shape and thickness are similar and if the 2 really look close in design.

What many do fail to realize that even the balance and weight of the parts can slightly impact how they behave. Not sure how much dyno and design time went into the DISA, but BMW did not even need to put a DISA in these engines, but they found some appreciable gains, that for the extra time, money and effort they determined if was worthwhile and somehow got the idea past the bean counters.

I am still amazed how good the fuel economy is for these engines and cars and how well they do perform. A lot of thought and effort has been put into systems to get more power, economy and improved emissions out of these engines. Things like Double VANOS, DISA, Heated Thermostat, Intake and Exhaust manifold, Combusion Chamber Design, and even all the way to the exhaust butterfly in the output of the muffler.

Each item by itself does not add up to much, but all the small tweaks added together makes for a better package and it why these cars are so popular and why we are all here.

Fuel economy isn't that great, and isn't the valve for sound?
