I want to add a bigger grin factor to my gt but I don't want to cut it up. So, the 2.4 seems the most obvious choice, I have a shop that will build me a turbo cheap so maybe a 2.4 turbo would be kind of interesting. But, there is a lot of buzz around rotarys. Lightweight, makes tons of power, and revs really really high. So, how much work is involved with putting one of these in? Do you simply grab a tranny out of an old rx7? How could you ever get that thing to fit, its pretty big if I remeber from when my friend had one (the tranny). You would have to make motor mounts. What about driveshafts, and linkage, etc. Are there kits, or do you simply have to make everything yourself? Also, which rotary is the most promising for a gt the 13B since there everywhere or a bigger rotary like the 20B (or would that one even fit?). My budget for the engine is going to be around $3000, and am not afraid to do the work myself, but am not going to have 300 hours of spare time this summer simply for the car (I wish I did). So what do you guys think, is it worth going to a rotary or should I stick with the simplicity of a 2.4?
