The spoon tb is also 70mm. Also, the science of speed s2k bore is also to 70mm. I think the main problem here is that your gas mileage would drop. If everyone makes them to 70mm, i don't think you should have a problem. Ill post back after I put mine on to tell if it changes anything.

Stock is 62.5mm and the standard overbore is 64mm. Proflow does a reasonable overbore quickly for about $200. I had lots of success with mine.
