pi swap

Labor is about 18 hours for a mechanic. Doing it yourself is possible but you really need to know what you are doing, have the tools and time. I paid to have mine done. I have no where to do it nor could I have my car down for a long time.
 
Mine is a daily driver, and for some weird reason it took me 3 weeks!
Not just because of the swap, but I as doing longtubes and a bunch of other stuff at the same time. But yeah, know what you are doing.
I had only done pidly nada bolt-ons, and this was some serious car tweakage.
I can barely believe I got it back together, and it hasnt blown up yet. But, you can do it. There are some good write-ups, but they all have a few holes, at least they did 2-3 years ago.

I did it all with out air tools..they would have been nice. Anyway,
Go for it! Or call me and I'll come help!
 
Install time depends on what you do while the heads are off, and how many times you have to go to sears for tools mid install. I painted my intake, valve covers, coolant reservoir, radiator cover while the heads were off, and installed an autometer temp sensor. All the prep for this took extra time, so all in all I took about three weeks, working mostly on weekends.

If you have basic metric sockets, deep well and standard, and know someone that has a torque wrench, then I would say do it yourself, you will save a ton of money and you will learn more about your engine than you ever could otherwise.
