fuel pump and spark plugs

[Cambridge_pulsar]

Wanna fit a boost controller and run no more than 1.0 bar, will I need to upgrade the fuel pump and spark plugs and if so which ones are the best :?:

i would say it is better to be safe than sorry.

i would fit HKS S40i Iridium spark plugs and a Walbro 225LPH fuel pump. might also want to think about an adjustable fuel pressure regulator although its not neccasary for a 1 bar car
