getting bigger TB might need some modification.
like cutting and joining plenum neck.
rebored just can plug n play.
im also looking for place to rebore my TB.
yeah...
if not mistaken rm80 for rebore throttle body..
sang engineering somewhere near ngai seng moulding...
quite expensive compare to rebore engine block only rm120-160 hehehehe(got 4 silinder)
my bnr34 was sent to workshop to replace my stock meter to nismo cluster, i thought its a plug and play. However, after the new cluster in place, i was informed that the rpm is not working... i need to change my ecu...
