Piston Slap: Ease of Right Hand Drive Conversion?

 

Sure, why not?

Hi Sajeev,

Greetings (again) from Australia. I've got a question regarding converting from left- to right-hand-drive. No idea if you're the right person to send this to (you could do worse – SM) but I'll send it anyway.

My question is this – is it (relatively) easier converting a mid- or rear-engined car from LHD to RHD? My very limited understanding is that, aside from things like the dash and trim that would need to be made, the biggest technical problem is where to feed the steering column, as it's generally got a nice path through/under the engine/ancillaries etc etc. So would it be theoretically easier if the engine wasn't there in the first place?

I'm assuming that things like the pedal box etc are easier to shift over.

This all came to my head looking at the new Ford GT, and lamenting on the fact that even if I had the money, I doubt I'd ever see one in our part of the world. That makes me sad.

Take care,
Jeremy

From what I've seen while upgrading my RHD Ford Sierra with engine/transmission/suspension components from LHD vehicles available stateside, the engine's location doesn't matter. Cars are modular, especially those with steering (rack) and chassis (subframe?) parts specifically engineered for RHD markets. The location of the engine bay on the body doesn't matter.

Steering columns, shafts and boxes/racks are never in the way of an engine, they mount to one side and the engine's in the center.  The hard part is making or possibly procuring right hand drive conversion parts that mirror the LHD ones.

Since the new Ford GT is far from a Ford-based initiative, odds are it uses steering, suspension and maybe even chassis components previously designed, tested and road legal in another life. This saves time and money, the last Ford GT was full of screwball parts: Focus steering column and engine air filters, Econoline inside door releases, signal lights from the 2001-2002 Cougar headlight assembly, etc.  Granted this new GT is far more expensive, it's probably far more bespoke.

But odds are the steering rack is made by a third-party that also offers a RHD counterpart. And it's designed to bolt into the same place as a LHD steering rack. Probably.

Now if you wanted to convert to center drive on a front engine vehicle, that's a whole 'nother story.
