All '01 and '02's LS6 Intake?
 

Do all ls1 cars after 2000 have an ls6 intake, including formys and z28's?

Yes they do

:stupid:

Is there any way to tell the LS1 from the LS6 while still installed on the car? I have a 2000 TransAm that was built very late in 2000. The build date of the car was 6/16/2000.

yup! Do you see a big ass tube going through your intake?? Or do you have a pump bolted on the passanger side head? If so you have an LS1 intake.

i dont think it matters when in the year the car was built, as long as its listed as a 2000, it should have ls1 intake. could be wrong, but im 99% sure im right.

but checking to see if you have egr will definatley give yo uthe answer

as stated ls1 intakes have a egr valve right before the tb (and egr pump on the cyllinder head)

also the coolant tube on a ls1 is different and the intake has a bigger space under it to facilitate the 2 coolant tubes (ls6's have only 1 up front)

keep n mind the vally cover under the intake is also different many change this out at the same time to imporve the pcv system

finally a ls6 intake is a bit bigger as in the dunners arnt so flat (mor curve to it) but less their syde by side its hard to tell

pretty sure the 2000's did not have egr, but it is still a ls1 intake, like the vettes...

the easiest ways to tell are the coolant lines, and the part number on the intake...

I've heard of a few very few factory intalled ls6 intakes on late build 00's.

Just verify the part number right on the side of the intake.

2000s did have egr, i pulled mine off last year,

and lack/possesion of egr or part# is only way to tell short of pulling it off

:nod:

is it true some late 2000 cars can have the ls1 intake and the smaller cam, because i know they used the smaller cam in 2001 and 2002 but they also installed the LS6 intake

2001 started with the ls6 intake. the 98 and 99's are ls1s and the 2000 has the ls6 block with the ls1 intake

2000's had egr and the ls1 intake. there is a line that goes in right after the throttle body on the ls1 intakes, that hole is not there with the ls6 intakes. just changed my intake to an ls6, makes 17rwhp and is a great upgrade. on mine i just smashed the coolant lines but you are supposed to remove them. be careful when installing because its easy to crack your Oil pressure guage (which i did). with my ls1 intake my fastest run was 13.55 and with the ls6 my fastest was 12.75, maybe i learned the track but alot came from the intake

The runners have a noticeable hump on the LS6. On the LS1, when looking across the runners it's a lot flatter.

Here is a side by side photo:

It's better if you can get down lower to look at the intake. You can see in that photo best by looking at the very back runner.

Looking at the LS1 intake, the high spot on the back runner is a little higher than the low spot on the runner in front of it. On an LS6 intake, that high spot on a runner is noticeably higher compared to the low spot of a runner next to it.

They used the LQ9 cam if i'm not mistaken in 01 and 02 to enhance low end torque.
