05 Ba Mkii Valve Springs

[mikea1988]

Hey guys I have done a quick seach and been unable to find exactly what I am after.

I have a 2005 ba mk ii xr6t has 70,000 on the clock

Mods

Full 3inch turbo back xforce exhaust

ugraded injectors

fuel pump

fmic

tranny cooler

Car is currently running 10psi at 270rwkw

I am wanting to hit the 300rwkw mark and leave it there.

What is most the feedback saying power wise ba mkii valve springs can hold? Is this a must if I want to get the car to 300rwkw at say 12-14 psi

Your help is greatly appreciated

[MX Dave]

Atomic, crow or Nizpro are all good value for money

If your mate is going to install them, give these guys a call if you want to save a bit of coin. I've been running them for over 6 months now with no issues.

$240...

thanks guys. will I need the actuator done for a daily 300rwkw???

You may not but it's a cheap and recommended mod for that power.

I have an early 03 BA Auto making over 300 with std springs. Who told you you need springs? What symptoms is it showing on the dyno or after a run? It's easy for people to say yeah get springs but they are not always needed and can be a costly exercise, no to mention a decent size job if doing them yourself Just be sure you need them first before you go buying a set.

As Sasha said ^^

I have a series 1 BF xr6t with 370rwkw on standard springs and has never shown any signs of problems.. The tuners told me once I they got it to 270rwkw it was gonna need springs without a doubt. They went another 100rwkw and it's still going strong!
