Default LS2 into C5 questions

its out of a 2005 GTO, so it has the 24x reluctor fortunately.

is my list of things complete that i need to do?

LS1 to LS2 TB harness
Knock sensor extension harness
Cam position extension harness
MAP sensor extension harness
Drill out the side bolt holes and tap for your knock sensors
Cut out a lower bolt boss to clear your engine mount
Oil pressure sensor harness to extend 2 inches

will my LS1 pan bolt up?

also, its a long block with no accessories. will i be able to swap my accessories over? or do i need to get LS2 accessories?

and any vendors wanna hook me up? haha.

You may need individual injector wiring adapters. Depends on your setup, etc

Yeah, I saw that motor and was tempted to buy it too. I just don't have anymore space in the garage until I sell off a bunch of parts and finish repair the transmission in my Grand Cherokee.

Good Luck with the build. Some guys notch the motor mounts when fitting them up.

You can get the needed harnesses from Caspers. I would swap out injectors to LS1 style to make the swap easier.

Because they are plug and play, elsewise you'll have to buy adapter clips.

Why would you swap accessories as the Ls2/Ls3 stuff will work too, except for the alternator and A/C. They use the same alternator bracket.

I would put it in, just in case you move or sell the car as most buyers would want A/C.

The water pump is lighter and thinner pulley, the Power Steering Pump has a metal pulley with slots in it for easy access and the bracket is stronger.

True, but like my father taught me" if it ain't broke don't fix it". He probably wasn't the first one to say that.

To each their own, I would rather do right once than to keep going back as I have better things to do with my time.
