Ls1 intake on Lq4?
Would i run into any problems if i put an Ls1 intake on my Lq4 truck motor. I'm new to all this ls motor stuff, but i do know that i want to get rid of that ugly truck intake asap... are thier different years of ls1 intakes or are the all the same? i read a little about the coolant crossover tubes... are those an issue? my Lq4 is an '03 and it's the cable driven 3 bolt throttle body... also, will i be able to use my truck fuel rails and injectors?
Thanks.
Thanks.

yea, i wondered about the truck intake making more power... this is going into a 68 bel air wagon... yes the truck intake is ugly, but it's not the end of the world and if it makes more power then it make it worth it... all i would need to find is a truck intake cover cause my motor came out of a van that didn't have room for a cover.

Someone correct me so its clear but I was under the impression from other ppl on here that the truck intake does not flow aswell as the ls6 intake does up top and makes less peak hp but does make more low/midrange torque?
The ls1 intake on the lq4 would just be taking a step backwards I think.

There is flow data on the intake on the truck site.

If you look at the data, basically LS1 intake equals the truck intakes so you really gain nothing! The LS6 flows little better than the truck one. But the LS2 90mm 4 bolt truck intake flows as well as the LS6 and it bolts in place of the 3bolt truck intake.
The truck guys quit the LS1/6 intake swap years ago as it wasn't worth the trouble for minimal gains.
You have to run a LS1 car WP with spacers or swap the pulleys. Then you have to relocate the idle pulley for TB clearance. As well as run the LS injector rails and injectors. Then you have to switch the injector plugs to the car style or buy pigtails as the connectors are different between the intakes for the injectors.
