will intake part number 12573572 fit on my 99 Z28 with no modifications.. egr, reloction of any mountings, etc..

 

Will have to delete the egr setup.Bolts up the same though!

 

cool thankyou

 

you will have to replace the coolant line that is under the LS1 manifold with the LS6 type that rerouts it around the manifold.

 

You can continue to use the LS1 coolant lines if you modify the underside of the LS6 intake.

 

any part #'s for the appropriate LS6 coolant lines? Also they do make the LS6 intake with the EGR hookup.

 

Nevermind, Texas-Speed has a kit to convert to LS6 for $40.

 

IMO you are better off leaving the LS1 style coolant tube or using both with a crossover, both ways you need to grind the ribs off the bottom of the intake manifold. The reason for this is that the LS1 crossover tube does a better job of cooling the #7 cylinder whereas the LS6 tube does not and as you may or may not know the #7 cylinder is usually the "problem" cylinder.

Save your money and just grind the ribs off the bottom of the intake and cool that trouble #7 better!

 

luna- did you grind the bottom of your ls6 intake? have you had any problems with this, do you have any pics of what areas need to be ground down?

 

I just installed my LS6 intake and I used a dremel to cut the fins off the bottom. Took about an hour to cut them off and clean everything up. Worked out great. Saved $40.00 on a new coolant pipe and plugs. And the #7 cylinder can stay cool!

did you cut all the fins off or just those in a certain area?

 

can someone post up a pic of the cutting of the LS6 fins to keep the LS1 coolant lines there? Thanx

 

I'm bringing this back to the top, I know I have seen the picture of the bottom of the ls6 where to grind the fins, but i've been searching for an hour and can't find it . If anyone can post it up, that would be kick ***

 

I installed the slp ls6 intake manifold this weekend and just used the blockoffs in the back. When people are saying there is a problem with the number 7 cylinder, how would i know? Does it misfire? Throw code? Just curious.
