The vgt dead horse

I have a he300vgt on my bench that’s eventually destined for my 98 12 valve.
I don’t have huge power goals just towing and daily driving.
Being on a budget I’m thinking I’ll just do the waste gate actuator to control the veins.
Most threads died 4 years ago so there isn’t much new info.
My question is could I just set the veins at a desired exhaust housing size and run it like that until I get it fully setup?
Any one else still running a vgt on a 12 or 24 valve?

My truck has 4K springs and pump tuning, valve springs. Nothing to crazy. Eventually I’ll throw some injectors in it
I’d just run an he351 but I was given this he300
 
Buy the lil black box or some form of electronic controller. To do it with a wastegate you don't really gain what the vgt has to offer. At that point you are better off with an he351cw or an hx40. Same compressor, less mess on the exhaust side to dik with.
 
I ran a he451 with the exhaust housing just pinned in the middle for about a year.

Well, actually it's still like that.

There's not really an easy way to pin it in a single position, but it is doable. (I have this ultra-custom hose clamp wrapped around the duck foot along with a couple hex nuts and then safety wired to the compressor. I can provide pictures but it's pretty embarrassing.)

Moke Engineering at it’s best...:hehe:
 
I took the whole turbo to a machine shop because I didn't know how to disassemble it, and asked them if they could get a mounting point of some sort installed onto the duck foot. They drilled out the shaft and went to tap it, kept breaking their taps. It's made out of some super hard metal.

How is anybody else mounting mechanical control rigs onto the Holset VGT's?

They aren't. They are buying the $150 controller so they can actually use the exhaust brake and take advantage of how the vgt actually works.
 
I’ve done a ton of reading on the lil black box. It’s an option for sure but it started adding up and for me in poutine and pancakes(Canadian dollars)
That and computer coding is a hair out of my knowledge bank.

Ideally I’d like to mount the turbo and run it “fixed” untill I got around to going electric
 
It’s been on my radar for a bit but the banshee stand-alone is pretty good from what I’ve read.

I also agree that the waste gage actuator will not control a vgt turbo like they way most people want.

So, what is this $150 controller of which you speak?
 
Man, I really LOVE the way my VGT works! :cool:
But it's supposed to be there. LOL

lil black box. Works well and has enough support anybody could do it.

OP put on an HX40 or a 351cw if you are going to run it fixed. There is no point in doing it at that point.
 
If that turbo still has the actuator on it you should be able to core it out for more than an HE351CW in decent shape costs. After running one of those there's almost no need for a VGT unless you just want the exhaust brake.

X2 on the LBB. There's no reason at all to try and run this turbo without an electronic controller. Toss this thing on and your 12V (with AFC tuned right) will feel more responsive and get an exhaust brake. Do that and a lower stall torque converter, and you'll have a pretty nice, daily driver/tow truck IMO.
 
You guys are biased against stick shifts. I can tell. LOL

100%! Ever since my first built auto. :lolly:
Still fun in sports cars though.

Well, since I consider my 6 speed manual 2014 way more advanced than my arcane 1998 12 valve 5 speed, I suppose I could stretch that to "Sports Car" status. :cool:

Just never had an auto that lived, or even shifted worth a darn.
They all seem slushy to me.

I'm running a banshee controller on my VP Truck. Truck has a 6.7 VP in it with a stock HE300VGT. Only fuel mods are a set of 150hp Mach 4 injectors. It took me a while to dial in the turbo to how I like it but now that it's set up I absolutely love it. The exhaust brake is amazing. It will even come on when the truck goes into auto high idle for warm up. I use the truck for towing my dyno and other trailers around in the summer and it is a perfect setup for me.
 
The lilbb is what I’ll do. I’d swap it out for he351 for ease of use but the exhaust brake is one of the big reasons I’d like to run this.
