RA2# features a longer wider front end with wider track to overcome 18R install. Also uses different crossmember, fits motor towards rear of bay.
In TA22 18R will give minimal clearance to radiator and position more weight further forward, increasing TA22 stock propensity to understeer.
2T-G can be good. 2T-GEU (EFI) will require modification to fuel system (more expense/work) where 2T-G (carburettor-fed) will utilise standard fuel system. In good power in standard form I prefer dual sidedraft carburettors to factory 2T-GEU EFI.
EFI allows for custom management and redeployment to suit forced induction applications. Factory 2T-GEU compression is conducive to mild forced induction applications, perhaps with 3T-GTEU manifold and CT20 if you want to minimise financial outlay.
2T-G can be built to 1770 with 3T crank and pistons (3T, flycut to suit, ~10:1). 1mm over is 1813, OEM replacement pistons are available in this size. 88.5mm/89mm pistons are available but forged and approximately $1200 per set. 88.5mm on 3T (78mm) crank yields 1919.
2T-G bolts in and fits standard transmission.
3T-GT will require relocation of one engine mount. Factory parts bin can be used to fit 3T-GT 'W' box, or standard T50 can fit but may fail. Again, ECU wiring and fuel system upgrade will be required, intercooler desirable for optimum performance, oil cooler and/or modification to coolant delivery may be required, and other small adjustments.
Beyond this other engine series require more work to fit engine/box and often custom tailshaft, etc. 4A isn't probably worth the work (dollar for dollar perfromance wise) as the costs spent on installation of 4A 1600 could develop a higher tune 2T-3T at 1770+/1919+ or turbo 2T-3T based motor.
3S motor (2L) could be good, though no experience here myself, PM Cool1. Probably a lot of work, not sure how it'd affect chassis balance etc.

Yes. It won't make a rocketship but it's a substantial technological and real-world performance/driveability improvement with scope to develop in N/A or forced induction form.
