I saw that Audi with WRX driveline.
Don't get me wrong,it is fairly simple especially if you have access to fabricating tools, space,and fabricating skills.
But after all I would say it would be at least 2x more expensive than 2JZ swap into some uncommon car. I have pretty good idea about it because I was considering either i5 24v or 2JZ into some more modern audi or bmw body for my next car.
Considering my lack of big budget I think I'll go with 2JZ.
I wanted best of both worlds for a daily driver(so no crappy,noisy,basic interiors and better looks). If I wanted a raw weekend toy I would go with Audi CQ and just swap a built AAN or 3B with BIG turbo. CQ's come with inline 5's just without the turbo so it would be easy fit and electrical harness would require little to no modifications. That could be done for $10k easy
