LS1 or LS2 intake manifold for LQ9?
I know I have to change water pump and the accesories brackets and on, but I need to go low profile to clear the hood.
Which one would be the best option for my LQ9 6.0L trcuk engine. LS1 or LS2 intake??
Thanks
Would I get better performance with a LS1 or LS2 intake? LS6 is not a option by now.
Please advice.
About the thottle body, the inlet on the Ls1 and Lq9 seems the same. Are they compatible? Can I use the LQ9 throtle body on the Ls1 intake?

The other issue would be compatibility of the LS2 TB with the LQ9 computer, harness and TAC module. It's easier to use the LQ9 original TB on the LS1 intake.
I would suggest finding an LS1 intake with injectors, it will probably be cheaper than buying parts separate.

Thanks for the good info!
I am going with the LS1 intake, or LS6 if I find a cheap one.
I also found this link which I think is very useful for anyone on this dilema.
LQ9 with car intake.
WITH THE $$$ I WILL BE SAVING BY NOT CHANGING THE ACCESORIES, I'M GONNA BUY A LS6 INTAKE INSTED OF A LS1.

The truck one will work just as well as the LS1/LS2/L6 on low and mid range RPM. But once you start pushing into the Higher RPM range and expecting to get every last bit of power out of your setup. then I would go with the LS6.
For most everyday applications and driving.. either the LS1 or LS2 will be ok and go with what is in your budget considering the fuel rails, injectors, front accessories and Throttle Body and of course driving usage.
Don't expect any gains with the LS6. Those with trucks that have done the swap, from the truck intake, noticed little to no gains. Most people don't bother with it now unless you just need it for clearance.
