dude i was going to try and find a polite way to say this but struggled, so.... stop getting so hooked up on performance vs other cars. the ZR is a new car and despite the higher power figure it aint that special. dont forget, the GA series engine was designed in the 80's, with no changes bar fuel injection. aus got vtc but they're jammy fuckers. the mg/rover engines have gone with the times due to being more popular, to the point of making a 'performance' 1.4, the 105. id say, out in the twisties you'd whip him. in a straight line there wouldnt be a lot in it. all boils down to how big your balls are. i mean, you wouldnt expect a 1.3 micra to beat a mazda 323f v6 down a 1/4 mile would ya? according to parkers? raceworx pasted one at shakeys years ago. get it on track and you'll be surprised, theres more to cars than parkers price guide dude... rant over.
