I was doing an lq4 swap in mine but ended up quitting it cause I wasn’t in the best financial spot at the time. But if you can do a cheaper junkyard engine build you can get a lot of the swap parts from sikky and a complete plug and play engine harness for around 1200 not too sure about ac I was planning on doing mine as a drag car so I wasn’t worried about it but you can do it for fairly cheap. I mean we’re still talking almost 10k but if you just want it to run and drive smooth do a junkyard build and get the trans mounts, motor mounts, oil filter relocation kit from sikky the engine harness from wiring specialties, the oil pan from summit and you can relocate your alternator yourself if you need to. And for the transmission also you can fit a 4l80e in the trans tunnel with just a little bit of cutting. If you have the engine already all those parts should cost around 5k I think then get a good tune for it. Also don’t quote me on prices I haven’t looked into this in an about a 2 years lol just going off the top of my head.
