question about external WG

[cvcsmkr]

i have a mini gate on its way. i will be installing on crossover.
what did you guys do to disable internal gate on stock turbo.
i know some have welded the puck shut. but is that a lot of work? does turbo have to be removed? if i just pull off the the tube to WG actuator shouldn't that work? and can i use the the stock boost solenoid, does it work good? or should i just get a manual controller? thanks...chad

Most people tack weld the puck shut, or just wire the arm up so it can't move. You need to force it to stay shut somehow. Unless I'm mistaken, "base boost" is determined by when the exhaust pressure overcomes the actuator's pressure, i.e. the exhaust would force the wastegate open if you just unhooked the actuator.

You can control an external wastegate with the stock stuff, but you either have to set the external up so that base boost and stuff are similar to stock, or reprogram the chip to match the external's characteristics. The stock setup is far from ideal, so configuring an external to mimic it isn't the best way to go (though I did consider it myself). You'd basically just be replacing the stocker with a stocker that flows better.

you can take the fender well out and weld the puck in the truck ( you just welding the arm that the wg attaches to in place)

Other ( and not as good) options are to 'wire' it shut by using some metal wire or clips or clamps or bands of some sort, by wrapping the band from the arm around the wastegate bracket on the turbo.

(I had my stocker like this for some time with metal wire keeping it shut)

Also, you can disconnect the vacuum lines for the stock wastegate (dont want it trying to push against your wire/weld).
You can remove the connector from the wastegate solenoid, and zip tie it out of the way (wont set codes)

If you weld it, you can remove the wastegate actuator and brackets.

what should i do as far as controlling the New Minigate.
i dont have to keep the stock setup, i just like to keep a nice stock clean setup, and i would be able to set boost in cab via ultimate. But if its going to be difficult can i just put a manual controller in series with wastegate?

is base boost the spring press. in WG?

i will not put an electronic controller in, i think they are to expensive, where as i can put that money into more mods. anyways it would be over kill for what i have.

I used a $20 pressure regulator from home depot. Locks into position. Now Im using an electronic controler, which although expensive, has some fantastic boost control.

DO NOT WELD!!! It's obvious you're into performance which mean that you'll be wanting an upgraded turbo soon. at which time you'll want to sell your stock turbo (you see were I'm going here) IMHO it's much esier to sell with no welding on it. I used safety wire and never had a problem

just my .02 worth.

i wired mine shut too. looks ghetto, but it works just fine and I haven't had any problems with it. the minigate has given me very good boost control using the $20 regulator from home depot that Ian referenced. i had a blitz electronic unit, but I sold it before I ever got to try it.

I hear ya on that, but if you inform the welder (or do it yourself) the tack weld could easily be removed since its external on the arm itself...
