from a GM dealership? you would happen to have a part number would you? or what would the MAf originally go on?

 

Great write up. What kind of gains can you see from this swap? Thanks

 

LS1 15whp/20 lb-ft
LS6 20whp/25 lb-ft

You can expect these numbers across the power band. LS6 will pull a little harder past 5000 rpm.

 

David so the ls1 and ls6 you will need the same mods for them to work?

 

Yes

He's got most of the swap stuff forsale

 

thanks I can't buy the stuff now but I'm kinda really thinking of keeping the GXP and putting a cam in it or a turbo. There is a few things I need to check out yet on putting a cam in

 

Cool Thanks, I might be getting in contact with him.

 

I feel like driving my car to one of you guys to do this for me....

 

Does it matter what year intake manifold you get?

 

No. Just different part numbers.

01-02 LS1 F body
04 LS1 GTO
04-05 lS6 CTS-V
2002-2004 LS6 ZO6 Corvette

 

is there anyway someone could measure out the dimensions of the TB adapter for me? i need the LS1/6 intake side and LS4 TB side. Just have a idea i want to play with.

 

Does it matter which rails and injectors we get? LS1 or LS6? Are they the same? I've got a LS6 intake waiting for me when I get home.

I'm a newb at all of this and am just trying to get all the pieces together to take to my car guy!

 

Use 28lb or higher EV6 injectors with a LS1/LS6 rail.

I have a idea to possibly make the install easier. But need to know about how much clearance there is between the highest point on the fuel rail and the bottom of the hood. It may or may not work, but I won't know till I get some more info.

 

I somehow missed this post, but Brian was kind enough to PM me.

 

Plenty of clearance!

 

I am out of room on the first page, so.. I will have to start posting here.
Thought I would share my PCV solution. This mod works great and goes across the intake manifold in between the intake and rear valve cover.
Basically, I took a 5/8-3/4 hose adapter, and a 3/8 to 1/2" hose adapter, and made the
3/8" fit the 5/8" and glued the two pieces together. I cut the adapters with a hacksaw and sanded the mating pieces flat. After sanding, I attached the fittings with super glue and a layer of gasket maker once bonded. The pics should explain it's self and give a better idea.
I bought the fittings from NAPA.



Used a 2" piece of 5/8" hose to attach.

 

Good deal, I started working on the design this morning.

 

And another completed, ready to bolt-on, ported, LS6 intake. This is my 5th intake swap LOL!
