the VG is a terrible motor. Quite possibly one of the hardest motors to work on, and one of the most problematic. I suggest you get a 240 with an SR swap. Its definately bandwagon, but for a reason. SR parts are abundant, the motor itself is extremely light, and with a simple mod, like rocker arm stoppers, you can easily handle 400whp on stock internals. Sammy from Tiger Racing swapped an SR into his R32. The S13 and s14 chassis themselves are run of the mill, but thats the price you pay. Its the RWD civic. Not only is it the best budget drift car, its such a fun car to drive. Be expected to be harassed by grand am owners though, they tend to not like them. Oh and Civic owners will ***** and moan because its a bandwagon car. <--- I find that ironic lol. As if an EG hatch with a B series swap isnt?
But I love Z's and if you have money, or a lot of time to work on them, then go for the Z, they are more rare, and a Z definately holds a name. Good luck and let me know how it goes.
