IN­TAKE AND EX­HAUST

NZ Performance Car - - Weekend Workshop -

The next prob­lem you’ll en­counter is the in­take man­i­fold. If you go to in­stall the Primera, Pul­sar or X-Trail in­take man­i­fold with the head, you’ll no­tice that the throt­tle body is fac­ing the fire­wall, which is not ideal. Any sea­soned fab­ri­ca­tor will be able to sort this out, and all they re­quire is your in­take man­i­fold so they can use your orig­i­nal run­ners to fab­ri­cate the rear-wheel-drive plenum onto them. This will cost you around $850, but will net you some se­ri­ous gains.

Last but not least is your ex­haust man­i­fold. Although the man­i­fold does bolt on, it needs some mod­i­fi­ca­tion to fit cor­rectly. Slot­ting of the orig­i­nal holes on the man­i­fold is nec­es­sary to match the man­i­fold ports to the head cor­rectly, as it needs to be slightly lifted. To make the most of the amount of air the VE head can flow, we rec­om­mend up­grad­ing from the fac­tory turbo set-up.
