What year did the JDM squaretop start?
 

Hi-ho folks,
I think I'm going to plug a Junk2 throttle body onto my JDM squaretop - but I don't know which model Skunk2 to get - the 94-97, or the 99-05? Have googled my little heart out, but no juice. Does anyone happen to know when the squaretop was introduced?
Cheers :)

Just in case anyone was playing along at home - found the info! Over on forum.miata.net, 29th Ja, 2015, Savington says "02-05 JDM and EUDM cars". Cheers Sav!

The squaretop manifold was the standard manifold on all 01-05 BP engines (non-MSM) worldwide except North America (Canada/Mexico too). Europe/UK got EGR, Japan and I believe Australia did not. Note that many countries had an NB6 which is the NB with a B6 engine, different manifold.

The squaretop is not "JDM" specifically.

Does anyone know what the side bracket was for on the EUDM Squaretop?

Also for ground wire connection (swapping NB motor with SQ Top into NA ), do I need the bracket from the original or can I just ground on the bolt where the bracket used to be? Thanks much.
