Ok, so I have a 99 Z28 M6 with Heads, Cam, and the norm bolt ons... I was going to buy a LS6 Intake coupled with a ported stock LS1 TB, but then I came across my buddy about to turn his Trailblazer SS Lease in... If Im not mistaken thats got the LS2 Intake and I think a 90mm TB or at least bigger than the stock LS1 TB... Which route should I go... Better gains with the LS6 intake or LS2??? Will that even bolt up do you think??? Any feedback is greatly appreciated... Thanks Guys...

 

I don't know what the specs between the two are but my buddy has an ls2 & put a ls6 intake in his. I'd say the ls6 is better according his actions but i dont know.

 

I ha ask this question before and was told the ls6 is better.

 

Yes the LS6 is better overall.
Also I'm not sure if the Trailblazer SS has the passenger car intake or if it has the Regular Truck intake. I've looked at them before but I never really paid that much Attention.

 

Awesome... Glad I asked... Thanks for the info... I'll be sure to go with the LS6...

 

passenger car intake i believe

 

If both are ported, then the LS2 is better. The LS6 is better than an off the shelf LS2 though.

 

DITTO

 

I thought I read that an LS2 intake won't fit on an LS1?

 

well ls6 fits an ls2 so i cant figure y a ls2 wouldnt fit a ls1??? injectors are slightly differant tho.

 

the tbss has a l76 intake which is a truck intake it is 7-8inches tall.

 

A ported LS2 intake will out flow a LS6 as well as a out-of-the-box Fast 90. All you need is a 90mm TB and the LS2 rails, and it will work on a LS1 motor.
