If anyone can help me with this it be greatly appreciated! Ok I want to swap my ls1 engine on my 2000 trans am for a GTO's ls2 what must be done for the engine swap other than the ECU change, will i need to re locate the engine mounts, transmission mounts ect. ????

They had an article about this in the last issue of GMHTP. It didn't seem like that bad of a swap. No motor or tranny mount changes. The reluctor wheel for the crank position sensor, knock sensors, and a couple other things are different. You dont even need a different pcm. I forget which company sells all the harness adapters but they are available.

Thanks for all the responses they all helped. What I am going to do is get a salvaged GTO for really sheep (I found one for 5600 rear ended so it should be good) and do the direct swap. THANKS FOR THE HELP!

why would i swap the engine? If that is your question well its for various reasons. I have a 2000 Pontiac Trans Am, it has 145000 miles on it its an automatic and i blew the transmission. An ls2 engine has 400hp about 95 hp more than the ls1, manual transmission, 30000 miles(I want a manual transmission because i have been doing lots of rolling races). I think that should answer the question why I'm swapping the engine.

You will have to have some changes done tot he GTO T56 to use it in a F body. I know the shifter setup is different and I'm not sure if it has the tourque arm mount on the tail shaft housing. Other than that, just use the GTO PCM and harness and you'll be fine.

what he was saying is that the ls2 makes 400 crank HP, not RWHP (to the rear wheels, through a transmission, etc) And for the ls2 to make that much more power than your ls1, you'd be making only 305 crank HP. Your car probably has 305 RWHP (to the wheels) and closer to 350 crank HP.
Thats there the 95 hp difference he was referring to comes from.
So no, you didn't write that, but it IS what is implied.

oh ok. I did not have my info right I thought the ls1 engines had 305 to the crank not to the wheels. Wow. hmm. lots of things to consider now.Either way I am going to pick up the salvage GTO this weekend. So it would only be about a 50 hp gain with the swap?
