MPi Mini throttle bodies

[Cooper1999]

Does anyone know if the throttle body fitted to the MGF / MG TF is the same as fitted to the MPi Classic Mini (48mm)?

I can't answer the specific query exactly but do know that 52mm throttle body is available as an upgrade for the MPi through Burlen fuel systems and the usual Mini traders.

FWD, thats why I'm asking - I've seen a couple of 52mm MGF / MG TF throttle bodies on ebay which are 52mm jobs (so perhaps my initial question, are they the same, was a bit misleading!). But before I start looking seriously for one, I thought I'd try and make sure it would fit easily.
Anyone else know? It could work out half the price of the Burlon unit.
