NA series to l32 swap parts Question

So as I get closer to dropping my l32 motor from a 06 GP. I am growing nervous of wondering if I have all the correct parts. What pulleys can I swap over to the l32? I heard the fueling system is different as well so I will have to get series 2 SC fuel rails and injectors correct? Do I need a alternator relocation bracket cause I know the alternator sits in a different spot on a SC car to a NA car. Wiring harness is that different as well? I imagine I'm forgetting some things. Any info is great. I just want to be fully prepared and not needing more parts while in the middle of the swap
 


Leave all the pulleys on the l32. Yes you need a l67 fuel rail and l67 injectors. The alt is in the same place on a supercharged car and an n/a car. The alts on 97-98 cars were in a slightly different spot but that is the only difference. I don't remember what you will need for a wiring harness. You will need a Gen 5 to Gen 3 TB adapter along with a l67 tb and you will need to have a custom tune done as well. I recommend reading through this thread. http://www.grandprixforums.net/threads/7763-Top-Swap-Info-and-Faqs-Also-lots-of-3800-Info
 
you reuse your rail and injectors, the alt is in the same place. what pulleys? you use what came on the l32. its there already.

and a tb adapter plate cause you cant your the l32 tb. its dbw. you got cables on the l67

Scotty his car is n/a so he has l36.
 


I also grabbed fuel rails and injectors off another l32. But I cannot use them correct sense my car is in 03 and fuel system is different?
 
you cant use the l32 tb. its drive by wire. you need a to get a l67 tb and a adapter plate.

you want l67 fuel rail and injectors.

and all the pulleys are all the same from your n/a engine, all but the sc belts pulleys. you'll need a sc tensioner, and two idlers, and one needs the pedestal by the crank. 3, 8, and 9 needs the stand under it

It would be super helpful if you told us what year you had. If you have a 97 or 98, you will need to do more. Not much more..but more.

99+ Swap:
Fuel Rails
Fuel injectors
Rear exhaust manifold
AC brackets if different
Alternator
Knock sensors (14 ft lbs)
Coolant sensor

Now the fun part, you need a TB adapter because you can not use a drive by wire on a cable driven car w/o a lot more work. Then choose your TB as well. I'd suggest an L67 aka cable driven SC TB. Plug your map sensor plug into the map sensor that has the vacuum line going to it. Ignore the 2nd sensor. Hook your evap connections to the new evap on the SC. Only things left is loading your new tune and reading up on removing the soleniod from the BCA

My car is an 03 N/A. So is everything u said what I need? And what is the solenoid from the BCA?
 
The boost control solenoid, controls the boost control actuator aka BCS and BCA respectively. You can unhook the soleniod and allow the actuator to work off vacuum. This keeps you from having to wire it in. Or you can get a kit from ZZP to add it it.

Yes.. you should then be good.

why knock sensors. i used an L32 bottom end in my car 2001 NA and didnt swap them out? i havent had issues
 
They are different. Don't tell anyone..but I'm running the L26 ones in my 2000 NA as well, but to be correct...I suggested it. At this point, I don't remember what it is that was different (sensitivity etc) but there was something that did make sense to change them.
