Been scratching my head while sorting out my engine build, I have a Cosworth 2wd red top 205 block engine to go in an escort cosworth shell.

I basically have the engine and manifolds, thats it. So no wiring loom, no water pump, no PAS pump no thermostat, no radiators and no intercooler etc etc

What im wondering is which ancillaries should i use? 2wd or 4x4? i assume the 4x4 radiator stuff will provide better cooling or am i wrong?

I dont want to mix and match unless there is a good reason to in terms of performance as i will have to mix and match hoses too.

So what should i do? 4x4 ancillaries or 2wd?
