The McLaren MP4-12C has a lot to live up to, particularly since it was made by the very same company that gave us the McLaren F1 and subsequently the racing version of it, the F1 GTR.
I'd like to know what injectors are good upgrades for this engine (rb20det - 270cc). So far everybody come up with the Rx7 550cc injectors (direct fit, need to mod the socket a bit) or the GTR injectors.
