Right, I had a Nissan Sunny GTI-R for about a month some 2 years ago...
It was supposed to be a group N rallycar but I guess with a proper group A shell, big AP brakes, Proflex group A suspension and a very illegal engine it was what we call a mini-group A car...
The engine was a full group a engine with silly cams, God knows what compression and a restrictor on the turbo.
It would FUCK OFF at an alarming rate untill you hit 5-5500 rpm and it's like hitting a brick wall The way it catapults out of corners from on 2000 rpm defies belief but you are forever changing gears...I used to love hammering it around town wich is fun as you have loads and loads of corners and jumps (some people refer to them as speedbumps) but it's thirst, constant need for fettling (the cams or followers needed some specific maintenance, can't remember) and the lack of top end killed it for me. On the motorway you'd be in top and topspeed in a second and next thing you know is you're droning away whilst every mondeo passes you...
Oh, and it broke several gearboxes and diffs, had a whole case full of them in the garage wich were destroyed by the previous owner!

So I would advise against it and recommend a nice 400-400 engine with shorter final drive for more resonsive feel (less laggy) and proper accelleration!

Oh dear...a sensible response to a post by Phil from me...what is the world coming to???
