alright sounds good

 

Another update

Finished the DOD connector, here's a couple of pics with the lifter cover fully assembled:

Hmmm, need to replace the stock bolts with something a bit lower profile, I need to find something like the button top bolts that come with the FAST 90


Here's a bottom view that shows how the DOD connector plugs in:


And just for the hell of it, here's a shot of the bottom of the valley cover that provides a bit of detail of the DOD solenoids:

 

AWESOME JOB!!!! Keep us updated.

 

Just a bump.

Haven't worked on this or any of my other mods for a few months (boxes of parts are just gathering dust in the garage). I'm about 95% there on the intake, just have to figure out how to hook up the brake booster and MAP since I had to eliminate the fittings on the rear of the LS6 intake in order to clear the power steering resevoir.

Trying to decide if that can be relocated to the top of the intake like on the LS4.

 

Any new info on how the LS6 intake swap/build is shaping up?

 

I'm just about to get back to this project.

Spent some time a week or so ago replacing valve stem seals, valve springs, push rods and installiing 1.8 rocker arms...what a frigging pain in the *** that was on a FWD V8

At any rate, I've got a bit of tweaking to do to my tune, then I'll take it to a dyno for a baseline run.

Valley cover and intake manifold mods/adapter are all done and ready to go, so after the first visit to the dyno I'll do the swap, play with the tune some more and head back to the dyno to see what the difference is.

Work's kind of nuts at this time of year, so realistically there won't be any results to report until late September.

 

once you get the intake in and valley cover, list everything you had to do because i want to do the same once the weiand intake comes out.

 

How about an update???

 

Been busy with work - trying to wrap up a couple of out of town audits, so nothing to update yet.

 

Hurry.....I need this mod.

 

Maybe it'll be done by the 1yr anniversary of the thread.

 

Well?
How far did you get?

 

hopefully when the weather turns shitty he will finish it this winter...

 

That seems to be how things go. I get a bit stir crazy in the middle of our 7 month winter, and get more project related things done then

Somewhere earlier in this thread, I have pictures of the rear of the intake, I've shaved off the area where the MAP sensor would mount and have sealed off the area with a metal plate mounted on each side of the resulting hole, three bolts/nuts and generous amounts of RTV sealant between the plates. I have to order new seals for the intake runners since the ones that came with this unit look a bit rough.

I finally have my tune where I want it after installing the magnaflow, springs and rockers. The car's pulling consistent 0-60's of 5.5 seconds even on cold roads with all season tires (based on data logged using HPT). If I could ever get first gear traction, I'm sure 0-60's would be down to at least 5.3 seconds.

With the Comp 918 springs, I've bumped the first gear shift point to 6250 rpm (88 kmh or 55 mph), and am considering 6500, but I'm not sure what the DOD lifters can take (at 6500, that should be 96 kmh or 60 mph). Anyone bumped redline that far yet? I'm not sure that there's any point in bumping the redline any further until some airflow issues are resolved:
The question that remains unanswered is how much the manifold neck further restricts airflow. I suppose you could run a second MAP off the vacuum port located at the top of the manifold and see what pressure is present there. Maybe I should do that just to see if you can measure a pressure difference before and after the manifold neck.

 

when it is done I would love this mod as well....i never could do all this stuff though.

 

Ever think about retrofitting a kit and then selling them Tired? I'm sure there would be a solid 15 ordered from the LS4 section here, not even counting ClubGP.

 

Well, in my regular profession, I'm the equivalent of $70/hr. Don't think I could recover the 30 - 40 or so hours of screwing around with hand tools that it took me to get this far.

The thing is, tool wise all you need is a dremel/die grinder, drill press and a few bits to do this (and someone who can weld aluminum). The only part that is really fiddly is rebuilding the DOD connector.

If I was to do it again, I'd probably go with a LS2 valley cover, reposition the OPSU mount and add on a Fast 90 and LS2 TB. There's just a few wiring changes between the LS2 and LS4 TB's, and I've seen a LS7 valley cover modified to allow a 90mm TB to be mounted in this orientation.

I am willing to post up a 1:1 dimensioned drawing of the TB adapter for anyone who wants to give it a shot. The template is easy enough to make - I made my template by tracing the manifold flange and TB flange on different pieces of paper and then just overlaying one over the other with enough rotation to allow the electrical connector to clear the manifold flange.

 

Look at the truck 5.3 intakes, they are taller, and the mouting of the vacume lines might be differet, also look at the 5.3 on the trucks with DOD

 

Update Update Update Tired, in the dead of winter, you SHOULD be working on this

 

Ah, but all the nice comfy inside work is done. I'm not really into doing mechanical work in an unheated garage at -20*C (-4*F)
