Hey guys, I have been running an NOS 5151 kit on my car for 15 years. The plate that came with it back then was a 48mm. I now have a 52 mm throttle body and its flow it blocked by the 48mm plate. Does any one know of a 58 mm nitrous plate? I found this one for an LT1 and was wondering if it would work. Also is it true that the newer NOS 5151 plates are 58 mm?

Thanks

 

You might want to check on ebay. A while back there were some plates by a company that wasn't N.O.S. but they would work anyway. The only downfall to the plates I saw, was the price.

EDIT: The ones I saw on ebay were also Nitrous Outlet but they had size specific plates like a 58mm one but it is $300:O
