Touchy subject for me, some i love, the majority i hate, all the twats that drive around with their clutch in, rutting away, in badly panelled 626s and DXs with retina destroyingly bright paint, chinese knock off modgies, 7 million inch drain pipe exhausts that scrape on everything and deafen peope a mile away and their fiters sticking out the bonnet on top of a horribly ''tuned'' IDA i cant stand, theyre just posers imo, in it for the trendiness and nothing else.
As an engine, i think theyre genius, not the most efficient or powerful, but damn clever and the noise (when combined with a good exhaust of course) is awesome

Small size and relatively light weight is also an advantage which makes them an idea engine for a track car.
Would love a jet-black widebody Series 4 RX7, 20B turbo with far too much power on massively wide JDM rims

, or a gunmetal 13BPP N/A carb'd RX4 on Equip MkIIs as a bit of a backroad weapon, half the reason being Series 4's and RX4's seem to be the most disliked of the RX family, and theyre a bit less common than the usual S1-5, RX2s and 3s etc.
