Ok well i just got paid and am gettin ready to go pick up my LS6 Intake manifold and keep hearing about plugs and coolant lines and all this other stuff and am starting to get nervous, im getting a brand new manifold from a guy and am only paying 300.00 for it but he didnt say anything about having plugs and lines and gaskets and all that stuff, am i going to tear into this project and then have it turn out a nightmare and have to spend a ton of money or can i just delete all my EGR stuff and bolt the thing on and go??

You can do 1 of 3 things from what Ive seen, for the coolant pipes. Plug the two rears and run one LS6 type pipe on the front, run two single pipes on the front and rear cross overs <----Like in the link(some people even run a rubber hose to link them), or just keep the LS1 coolant piping and grind down the tabs on the LS6 intake.

Heres a write up.

write up = Win but just grind on the LS6 the tabs and be careful not to break your OPS Unit at the back of the Intake.. If it doesnt come with gaskets use your old ones... These are the tabs you grind down.

so the coolant lines are underneath the intake manifold? also the gaskets that are missing off the one im buying are the round runner gaskets will my stock ones work? if not how much are those going to be

i would recommend replacing the crossover pipe gaskets,also if you run a rear pip you could just use a vacuum line rubber cap with a clamp to seal off that line instead of the bolt/rtv method,atleas that is the route i went.

Break all the tabs, and buy new gaskets there only 22 dollars at a local autoparts store. Dont mess with anything else

I chisled the fins from mine. No problem at all.

I have been reading a lot about LS6 intake installs as I have just recently ordered one as well. It seems like an easy job... the hardest part being 2 things:
1) Oil pressure sending unit. Seems nearly everyone breaks this regardless how careful they are. Best prepare and get a new OPSU ahead of time and dont forget the special socket needed to remove it. Both should be had from your local auto parts store.

2) Coolant lines and fins on ls6 intake. Unless you plan to go with plugs (which I gather isnt a good idea) you are going to have to break off the fins (like in the picture someone posted above). This seems to be easily do-able with a hammer and chisel though.

it can be done without breaking the OPSU,i can attest to that.

I think the OPSU gets brittle with age and heat cycles. I took my stock LS1 intake off last night with no issues to the OPSU. I physically touched it gently with my two fingers and it litterally snapped right off. I think anyone taking the intake off should just change it anyways no matter if it breaks or not.

the reason people break the OPSU is because they dont pay attention to the vacuum hose running from the back of the intake to the brake booster. it catches on the OPSU and when your trying to pull the intake forward, it breaks. ive had my intake off 3 times and never broke it.

Its better if you can get someone to help you, When they start pulling the intake .. you can reach and guide the brake booster line around it at the same time.. thats it, real simple.

just grind down the tabs like said above

I paid VERY close attention to the vacuum hose on the back and still broke my OPSU. It was just too brittle after 115k miles... I think from the dealer it cost me 50-70 bucks for a new one..

Thanks alot guys, everyone here on LS1 Tech so far has been awesome, living in Idaho like i do most people dont even know what an LS1 is, ive called machine shops and performance shops all over around Idaho and most of them have never heard of an LS1, i ended up having to call Texas Speed just to find out what cam im going to need.

So being an LS1 owner you probably now how rare they are in this area.

my parents moved away from there back to Ohio in '89 when i was a year old. but i have been out there a few times to visit family and the few LS1 cars i seen were either stock or riced out.
