do you think is a good idea to replace my Honda CRV 2004 2.4 I-Vtech with 2007 Acura RDX 2.3L turbocharge Engine. I want to improve my performance and acceleration too or what about the Honda S2000 engine is that also a good idea but the S2000 engine as manual my CRV is automatic so please let me know thank you.
i dont know as much bout the rdx but i can tell you that the s2 motor will not fit because the s2 motor goes front to back and the crv motor goes side to side and the only cars that have had the same motor as the s2 (f22) are the accords and they were side to side but their are usually older accords or preludes and are not as fast as the s2000
the s2000 is rear drive and the crx is either front or awd, either way no transmission will work for you. your best bet is to find an rsx type S cylinder head and ecu and put it on your block.
