VGT turbo controller for lb7??

[Djm71199]

Title basically explains what I’m looking for... I know what hardware I need, but I’m not sure what I have to do in order for the turbo controller. All I’m chasing with this swap is the sound. It’s not going to be a tow rig, race truck, or anything like that. I plan to do a swap into my escalade once I buy my new truck and want it to sound good, lol. Also if this isn’t in the right place please let me know or move it...

Moved to Turbo Talk. Cant say Ive heard many people put a VVT on an LB7. Good luck.

Thank you sorry, didn't see a turbo talk sub forum! But I saw a youtube video of it and they sound amazing! I'm sure people will call it stupid, but I personally enjoy the sound of a VGT Duramax , especially for what I have planned!

The VGT do sound awesome! I have heard a LB7 with a exhaust brake and it had a hint of sound like VGT turbo at idle.

It is doable with either a small PLC (Stamp for instance) or a feedback analog circuit. Making it "smart" would require a lot of work, but a simple boost control is rather easy. These are non-ECM stand alone solutions.

It’s been done. Never done to work like factory.

You’d be better off putting an lly top end on your truck or selling it and getting another truck.

Fleece sold a controller years back, but I don't think they sold many. You might be able to find a used one.

So I've decided to take the lly top end route lol, does it have to be lly or can it be lbz? New to this whole thing, but not to engines. I've worked on a lot of gas vehicles but not diesels. Heads, injectors, ecm, ficm, turbo, what else would I need..?

 

[Djm71199]

Quick question actually, ideally would it be more reliable to just get an lly? Or is the lb7 transmission/drivetrain just as reliable?

 

[clrussell]

It would be a hell of a lot easier to just get an lly truck. Overall the same drivetrain as the lb7, but better

I'm curious to see if DPS will release a kit for the duramax? They have VVT kits for cummins currently on the s300 and s400 turbo platforms that may be an option

I believe if you have a s300/400 then it should work.

 

[bigmackmiller]

No . It's all different l5p vs previous years. The only way to do that is how banks is currently doing it cummins style with the notched fluid dampr.

I have modified my plans a little, but I did get a sub box ordered from MTI Acoustics. I got a stage 1 with up firing and recessed subs. I had it finished in black carpet and picked up an emblem to figure out something cool to the front of the box. I’m hoping to have the box next week.

Believe you are correct, wonder how hard it would be to dial in

That uses a mechanical wastegate controller on a vgt turbo. It works, but would defeat the purpose of having an on demand turbo brake, and have you running sky high boost killing your mpg's at cruise I would think.

As far as I know DPS offers it with an electronic actuator that can be programmed.

That was my understanding as well

Seems they offer both. When I looked they only show a picture of a mechanical wastegate version, but in the lower description they say they offer both.
