'Tis not the forum to discuss it, but from what I know (and narrowing down the Suby models can be tricky, year to year variances etc) the V-limited, STi RA is the cream of the crop.
The STI and STI RA engines are the same, but the RA engine has some little changes, eg the valve lifters which enables it to rev higher;RA engine has 7,800 rpm red line in comparison with the Standard STI that has only 7,200;The RA has slightly stronger internals. bhp should be about 21 more than the STi .The RA ECU has a fifth injector, and is lightened so the power increase makes even more of a difference. The RA has different gearbox ratios than all other STi's, for harder acceleration and less difference between gears.
I've piloted the thing a fair bit, and it's quite a thrill....until I get back on my much cheaper and much more factory standard motorcycle. Then the Suby feels slow as a retarded elephant.![]()
