I am building a 'street truck' based on the L92 block/heads and the L76 intake. I don't need either DoD or VVT. Question: What do I need to remove and replace to lose both DoD and VVT in the L92?

 

I am working on an L92 now. So far, cam, chaange 8 lifters, plug some oil holes, LS2 Timing set. As I get further I will have a complete list.

I have a GMPP L92 Crate engine that I will change the cam, add the L76 Intake and see how she runs.

The guys at SDPC might have this info right now.

Thanks Robin...my L92 block and heads are downstairs now. I just ordered the L76 intake 'kit' from SDPC and plan on selling the 'drive-by-wire' TB on ebay. Could you share info and p/n on your build?

I had torn into the L92 expecting to find the Active Fuel Managment (DOD). It turns out this engine didn't have the DOD installed. I talked to several people who are working with this deal. They say that some have it and some don't. I am told that they dropped it from some of the L92's at some point.

I have been collecting more information. I had talked to some cam guys about a cam specifically for the Active Fuel Management enabled and trucks.

This engine did have a cam phaser. It's going to be difficult getting a passenger car water pump over that cover. I have heard about a soloutin and will check it out.

Right now I am busy on the LSX engines for our Nostalgia Pro Street car. The L92 has to be on the back burner for a little bit.

There is no way of controlling the phaser right now so you may as well ditch it, and replace it with an LS2 double timing chain. Then you can use an LS2 timing cover and an unmolested water pump. Or if you want to keep it the way it is here is a link to wegner motorsports water pump spacers, only $30:

There is a company that has a stand alone system that allows you to control the phaser. It's a complete fuel management system. I will be talking with them about some testing and a article to talk about their system.

More later

Wow. Please post up when you figure this out. It would have some amazing potential.

 

Unless you're talking about some crazy expensive BIG STUFF 3 with some serious custom OS, I'm pretty skeptical. And even if you could get it to work, then you have to worry about ptv clearance like no one else. Which may end up hampering the amount of lift/duration you can use till there isn't any benefit overall. Until some one else does the R&D I say Ditch it and go regular LS2 stuff.

 

Are they now producing an L92 crate engine? Thats what I would like to have in my car, a stock, or as close to stack as you can get, complete L92 crate engine. Of course I would consider an L76 intake. Where, and/or when, can I get one? JB

 

Any updates Robin?

 

hello

 

Mast Motorsports will be releasing a L92 crate engine for sale within a couple months. We are currently finishing up development on our stock L92 and L92 HO crate engines. Our wiring harness and controller package is the VVT capable standalone system that Robin mentioned and is available with our turnkey crate engine packages.
