GTO LS2 into Iroc I'm having trouble finding info on LS2 GTO engines,
I'm getting ready to swap an LS1 into my Iroc but decided to go to an LS2 6 speed from a GTO,
am I going to run into issues that I wouldn't with the LS1,
I know they are a similar engine and trans but the little differences can throw you for a loop
I plan on using a spohn LS swap k-member, and trans cross member,
I know I'll have to get an Fbody oil pan, but am not 100% sure if its a direct swap on to the LS2, I'm assuming it is,
the accessories look similar where it counts
Thanks for any help,
hopefully I can start getting parts ordered next week

Will be similar to the LS1 swap, but you will need an aftermarket Throttle body (90mm cable driven style).
The LS2's Throttlebody is electronic.
Note: if you already have the wiring setup for an LS1 you will need a cam sensor cable extension (LS2 reads the cam from the front gear, where LS1's read from a sensor on the cam close to the back of the motor).
Most of the accessories, if not all of them that you will need are interchangeable with the LS1.
Also the GTO LS2 have a 24x crank timing gear, which is the same as the LS1's. If you would have gotten one out of a 07 or later blazer or vette it would have a 58x crank gear...
Good luck and enjoy the weight loss (iron 305 or 350 weights more then aluminum 364)
