well id say the JDM b18cR is the best. if im not mistaken the engine is 5 kw extra compared to audm b18cR. tuned it should give out some mad power not forgetting that you have altered your power to weight ratio and if its a eg breeze you cant go wrong since eg breeze had the lightest shell out of the eg range.

rex is a nice ride but as a daily ahhhhh i wouldnt settle for it. even with your engine swap in the eg your fuel comsumtion wont really be high and would serve as a good daily car and a beast when you want to let it rip.
