I did say
uprate brakes and suspension.

Still not sure if it's such a good idea though. MG did do a V8 version of the BGT, but never the roadster, I should really take that as a clue.

Alternatives are the 2.5l engine from a Triumph 2500 into a Spitfire, which is basically a soft-top GT6, or just buy an MGC roadster, which is a straight 6 version of the B. Not much of a challenge, except for the fact a good one is over 10 grand.

And the handling on a C is fucking awful becuase the engine weighs so much
and sits further forward in the chassis, giving a horrible nose-heavy pendulum effect. See also: every hot Audi saloon built from 2000-2006 ish.

I heard this too.
Apparently a bag of cement in the boot helps. Except if you need to put anything in the boot.
