My ultimate wish would be a flat6 build, but quite frankly it's way out my budget. Now I am on the fence as to whether I should just sell my car as a roller/part it out, or search for a low mileage 3.2 to swap in.
I have read a couple of conversion threads and articles about swapping a 3.4 into the car, but it appears to be less straightforward than I thought. I didn't know there was much involved in the ways of intake plumbing, MAF, DME, trans mount, etc
Is it really worth the hassle, or should I look for a 3.2?

2000 or 2001 996 3.4 is the easiest engine to swap. After listening to the engine run, perform a compression &/or leakdown test to check for excessively worn cylinders since the 3.4 engine has the thinnest cylinder walls. If the engine passes you still need to remove the cam covers & replace the VarioCam actuator wear pads. While you have the lifters out clean & test them. Reassemble the cams & covers & set cam timing. Now you are ready to do the LNengineering IMSB retrofit. Now you should have a reliable engine ready to swap. The long blocks are nearly identical so remove original engine & position 3.4 side by side & swap external parts that are different for 996. This swap will run great without reprograming the DME.
There is a rebuilt engine in the classified thread designed for this application.
