Nah,,, you guys have it all wrong,,, you will definately need to totally re-design the entire front end of the car,,, fit lowered P76 MacPherson struts & Lowered yellow King Springs,,, then fabricate a decent steering rack position mounts ,,, remove the entire rear suspension assy & replace it with a lightweight version of the Datsun independant rear end,,, then swap the engine over the a Twin turbo charged, injected, bored & stroked 5lite alloy V8 from the late injected Range Rover with the 4 bolts mains... add some fuzzy dice from the interior mirror & some clubman GT stripes & then both your mouse & your pussy will become best friends with very neutral handling
easy-peasy
Edit---> Oh & by the way,,, all the above is only to be attempted on the coupe,,, whatever you do, just please don`t try this on a sedan kids,,, Please just the coupe

& fit some decent Phat wheels & tyres so it at least looks half tough
& By the way Sam,,, if you want to make that engine work (better) then forget using that engine all together,,, but if you insist on trying, then just stuff a turbo onto it,,, the head design is just pure YUK!!!
