Actuator Question

[Jim]

when you send in your standard turbo (rb25) to be highflowed.....do they change your actuator to be able to run more boost or is the standard one sufficient ?

[LBR33]

yes most places normally do

[Jim]

ah cool cos i have a highflowed turbo in my car but it was already highflowed when i got it......and im running a turbosmart boost cont (those shitty ones) and after putting it onm the dyno my mech said it wont hold more than 10psi so just wondering if i needed to change to an elec boost cont and also change the actuator....or just one of the 2?......what u guys think?

and whats an actuator worth these days

cheers

If an internal gate turbo wont hold boost , with a reg, its usually the flap being blown open by the turbo to motor backpressure. and a higher spring pressure is needed in the actuator.

i recieved my high flow from GCG the other day and it didnt come with a new actuator. i have a profec b spec 2 and i have no probs with the actuator.

[Jim]

zilla01 what boost are you running?....i had the profec b s2 on my old r33 and it done it job just fine so i was gonna go with that again

i have all other mods needed such as pfc/injectors/pump/fmic so looking to run 18psi.

I got a GCG highflow and used the stock actuator. I only run 0.9 bar but it's no trouble.

hmmm.....i have a gcg highflow and it came with a adjustable acutator
