How easy to Install new manifold?

I'm looking into installing a new ls1/ls6 conversion manifold. How difficult is it under the trans am overhang over the manifold and is it really worth the headache?

Im doing mine this week bro. ive heard its not too bad. you just have to be careful with an oil sensor towards the back when you are taking the ls1 off. i have another thread on this somewhere. ii here there is a good gain from them. good luck.

i did mine and its not that difficult. Its kind of a bitch getting under the overhand to get some of the back bolts but not horrible. Wear some gloves so you don't get all cut up. When you have the old manifold off make sure you have the intake ports on the heads covered up, so nothing falls in them. Also, be careful with the oil sensor like mentioned above - i broke mine ($60 at dealer for new one)

And yes you will feel a nice gain. I really felt the extra power at the top of the powerband.

its real easy...just unbolt it, take out the fuel rail. Put the fuel rail in the new intake...bolt it back down. Take maybe an hour. And the back bolts are a pain in the ass...I recommend buying a 10mm speedwrench. Makes it a lot easier.

Its recommended to unhook the fuel rail completely. Something about a "special tool" to snap off the fuel line. Fuck it. I just pulled it aside, still attached. 4 times Ive done it now..
