52mm TB be ported into a 54mm?
why couldn't i just port my 52mm TB into the same size as the 54 or 58? is there not enough meat on the tb or are the sensors different?

I believe both are different. What 52mm TB do you have? Why do you need one larger than 52mm?

you should be able to sell your 52mm and pick up a 58mm at the same price, if not a bit more...

I have seen some 52mm throttle bodies be ported out to a 53.5mm, but that would be a waste of time in my opinion. I agree with Flusz28, just sell your 52mm and buy another one for almost the same price
