I was wondering if you can throw in a bigger engine into the 1.9 Z. I suppose the 2.5 L would probably fit, was wondering if anyone did it. How about a completely new motor, a buddy of mine can get my the 3.5 L V6 from Chrysler 253 HP for $2000, but it seems rather large. Anyone know what it takes? To preempt some typical responses, I can't afford to get a better Z. I wish... perhaps if I had a tax cut. If anyone wants to trade with me for a tip-top 1.9, just let me know. (ps: it's got awesome customizations!!)

Much bigger engines WILL fit, there was a Roundel article about a Z3 with a 5 liter V12 in it. It fit with few body modifications. Get the tape measure out!

But, keep this in mind: engine swaps are REALLY hard these days with DME etc. Unless you're a real genius I bet it would take 6 months to a year to do the Chrysler swap. Plus figure in lots of hidden costs, motor mounts, cabling, adapters for wiring, etc. In the long run I bet it would be cheaper to upgrade to an M.

I would also point you towards the Downing Atlanta supercharger, I've had mine for over a year with excellent results. Figure $3500 and a weekend or so of work for the average guy.
