Default ls2 intake vs ls1 intake

I have just bought an F.A.S.T. 90 off a friend with an ls2. it has the lower part of the intake(not sure what its called) that is black. he also threw in the fuel injectors he has which are stock and im not sure if they will work on my car or if they are any different at all. i was wondering if the intake and injectors would bolt right up to my ls1 or if i would have to make any type of adjustments. if it wont bolt up, what modification need to be made to make it fit from an ls2 motor to an ls1 motor? thanks in advance.

injectors and, i believe, the fuel rail mount differently between the two.

The 90mm will bolt on, use your rail and injectors. The LS2 injectors are 34lb/hr and are a different length and require a tune to make them work correctly.

Keep the injectors for later upgrades or sell them.

Don't forget to change the valley cover bolts or your will crack the bottom of the intake.
