Ls1 -> ls2
I am almost ready to switch over to a fresh forged LS2 402.
Need some help with what fits / doesn't fit in LS1 to LS2.
Do I need a new oil pan or will my LS1 pan fit the LS2?
Do I need any new/different brackets for things like water pump / alternator / A&A SC currently on LS1?
Is there a extension required for the knock sensor - seems I heard they are mounted in different places on LS2 vs LS1?
Will the clutch / LS1 bell housing mount ok with the "old" style torque tube - to the new LS2 engine?
I have changed the intake manifold years ago to LS6 on the old LS1 engine - will that intake plenum work on the LS2 without issues?
Thanks for you help!
