My LS2 intake install Installing the ls2 intake was just as easy as the LS1/6, All the same things need to be done except the ls2 already has a map sensor port up front. But using the stock ls4 fuel rail and injectors was awesome especially for those not wanting to cut your alternator bracket, like you would the ls1/6.
Cutting the VLOM was a breeze, being the soft aluminum that it is a dremel will easily handle the reworking of the oil passage. If i could do it all over again id just drill throgh the non cut tower into the feed port and tap it. but thats another story. Next time this valley cover cover comes off itll be because im pulling the heads etc...
Its good to know the DT headers crossover pipe fit but barley. the crossover was damn near touching the coupler so i had the crossover shortened 1/8 inch and rewelded at the ball flage joint. now i have plenty of space.
Side note. Yes I know how shitty these things are factory and assosiated issues
This however is no stock ls2 intake. Its been plastic welded around the seems on the outside. Inlet is 92mm runners are port matched to the heads. And beams have been taken out. This is the same as the stage 2 port job. And holds its own against the ls6 if not better. I'm also using the 90mm tb with that's ported polished as well.
here are the pics from my LS2 swap hope this can help give a visual.
the VLOM cover rough pic of what i was doing the inside.
all welded up
my modified oil cooler block off plate **note The corvette OFAC is not a bolt on item. the holes arent aligned the internal shape is smaller.
here is where the plate is located
Picture of the modified brake booster fitting and additional fitting i added to the front of the manifold
everything mounted up
Also note 05-06 GXP's can use the longer oil filter PF61 acdelco for more oil capacity.
Misc notes.
you will probably either have to peel your map harness out the loom or use an extension, The TB and factory wiring harness can be a tight squeeze with the hoses in the area, my loom pressed against thdogbone mount to the cylinder head, which carries alot of heat. I made sure to wrap with some cloth friction tape then reflectix material so my loom wouldnt burn against that hot *** aluminum
Thanks for looking and if you have anything for me please feel free to ask.

Nice! Did you use a screen on the ls7 maf ? My tune was way off when I did my ls2 swap. My setup is close to yours difference being I used the ls2 injector , truck tb,and cam.

[QUOTE=91parkave;17621889]Absolutely but in stock form the ls2 manifold has its downfalls. Which I'm sure you're aware of.
Oh yeah which is why I'm going with a FAST but I'll probably do a little porting on it for the SS. Thanks for the info man.

i just had peak speed port a ls2 intake and i bought a 92mm fast tb. I have a 1999 ls1 and the map sensor was in the back. is this going to throw my tune way off? also there is a vacuum line that normally goes in the back of a stock ls1 intake do i just break off the ls2 vacuum line plug drill it and use that or is there something else i do? Im two days away from install>
