I’ve pretty much settled on building a 2.3L Stroker engine using my 4G63 6 Bolt block which increases the displacement of my engine by 0.3 Liters just by adding a more aggressive crank, which in turn lengthens the stroke and increases the displacement. My biggest reason for this is that my Talon will always primarily be a street car, but I see myself doing more track type racing than drag racing in the future, and I’d like the extra torque of a larger engine to have a reasonable exit speed on turns. Also, it allows me to throw a good sized turbo on with a custom intake manifold and aggressive cams without losing too much bottom end, or having to worry as much about turbo spool-up time. Since I’m not looking to build a high revving engine and have to pay the expense of having things such as titanium valve springs for such an engine, I think this is the way to go for me.

Essentially the easiest and least expensive way to do this is to stick a 4G64 Crank into a 4G63 block with some custom made pistons, and you should be good to go. I found a Stroker FAQ which talks about this a bit more in length. The 2.3L Stroker seems a lot easier than the 2.4L Stroker, which requires you to track down a 4G64 block, drill oil squirters into it, and order a bunch of other odds and ends to get it to work correctly. No thanks!
