With that kind of perspective you will definitely have to go for triple
DCOE Webers.
But why not go for Lucas injection? With a TR5 camshaft, porting, CR
and exhaust system to match you may get up to 155 bhp on the 2 litre. But
you'll definitely need the Mk II engine with large valves as basis
for any serious tuning, the Mk I is simply too hard to find parts for.

You'd have to watch the GT6 gearbox, though. It will live a hard life.
