hey guys!
i have a 93 Barina here in Aus and im running an 8v sohc carby engine

the bottom end is great and doesn't make a peep but the valve train is a little noisy when she gets hot. i want to put a Dohc head on it.
no i know i will need to change the headers and intake and get a wiring harness and ECU for the new head. im probally going to use the MK1 harness and stuff so i can use the vacuum dizzy on my 8v head. that is depending on how much it will all cost.
im not really keen on getting a whole new engine as the bottom end is still in good nik.
my question is do i have to get a new fuel pump? does it need a bigger one?
if i have missed anything what else would i be up for on this, as in what other parts would you recommend under the hood?
