370z AT With Stillen S/C And The Upgrades

brucelidat

Can anyone tell me why these upgrades were needed as well? Are these necessary/recommended for the kit to run well? Or are they a bit over overkill to be safe and cover your bases in case you want to push it further in the future?

gt-r spark plugs
Turbosmart Kompact Dual Port 25mm BOV
DeatschWerks 850cc Injectors
DeatschWerks DW300 Fuel Pump

I would say more for safety but pushing the kit further well from what i have seen here the kit is very good to 400-480whp after that the kit pretty much runs out of steam. Either you end up blowing the motor by upgrading some parts of the kit or upgrade to a turbo kit.

Jordo!

The GT-R spark plugs I would highly recommend, as for the Turbosmart BOV that's just for show off sound effects The DeatschWerks Injectors and fuel pump is not a must but the deal I got on it I could not pass on them and thought maybe I could squeeze a E85 tune from them in the future.

Just the spark plugs are needed, HKS make some as well, I'm running those in mine. otherwise I'm running the standard stillen kit apart from the frozenboost heat exchanger and with the 9lb pulley.
