help and advice?

[callumGT]

I have a HKS one ont the car at the moment but its not working right and for the set up I wnt to run apparently I'm best off with a standard actuator,

My set up will be:

cast pistons (75mm)
FMIC
re-located air filter
baileys DV
HKS EVC 3
boost at 1.1 bar,
stardard actuator
FCD
FPR

You think its right the set up will require a normal actuator?

anyone?

If your boosting at 1.1bar I would say an uprated actuator would be better than the standard one.

Stick with the HKS.

whats the actual problem with the hks actuator?

Many people run the hks actuator as that boost level you talk about with no problems, as have myself.

If your not wanting to use hks theres other options like jam (preset set to 1br)

Whoever told you that you're better off with the stock actuator for 1.1bar of boost...never ask their advice on these matters again. The only issue you may get from the HKS unit depends on what is being used as the main controller for the wastegate...the actuator or the ebc. If you want to set your boost and gains with the ebc, then turn the actuator down to stock boost levels (the stronger spring will still serve you better than the stock unit) then up the boost with the controller. Set your gain levels on the ebc until you're happy with the stability of the boost and the turbo response. If the actuator is controlling the boost levels (.9-1bar)and the ebc is just to trim and stabilize the boost(1.1bar), you may find smooth response and stability at 1.1bar a bit more difficult. This will be because the actuator is the unit raising the boost levels and leaving very little room for the ebc to control the wastegate via it's electronics and solenoid.

hks actuator is fine even for a completely stock car. will make the car spool up a bit quicker due to the harder spring.

where you from in suffolk mate?

Have you come to this conclusion from this post as it makes no sense to me!

your actuator is designed to run higher boost then your running, thus the wastegate is open. Buy a standard actuator from someone on here and you will hit full boost at aot lower revs

Have you shortened the rod on the HKS actuator so you have to pull it out to reach the wastegate arm? If your experiencing excessive lag, either the rod is too long and needs to be shortened, the spring in the actuator is too weak to hold the wastegate shut whilst the turbo spools or the wastegate isn't sealing properly. I would suggest you'd have to pull the actuator rod at least a good 3-4mm before it will reach the wastegate arm if you want to give the actuator any chance of holding the wastegate closed. There will also need to be a fair amount of resistance when pulling the actuator rod or this again will indicate a problem with the spring in the actuator.

The only reason I can think of for you to want to replace a HKS actuator with a stock actuator would be if the HKS actuator is fucked.

x2. End of story. At 1.1bar the stock actuator will NEVER be a better option over the HKS unit.

I had a HKS actuator and IMO i think one of best mods for ct9'd ep's. Holds boost well and comes on strong and a bit earlier.

I ran my stock actuator at 1 bar for a few days and it sagged and wouldnt hold 0.4 bar after, i have quite a few nackered old stock actuators here lol, id never re'use one

I sold him the car, his actuator has been modified very cheaply so that the owner before me could run silly amounts of boost, therefore his actuator is now useless and makes the car very laggy (wastegate open)

I told Cal he needs a NEW actuator and not a standard one but a standard one will be cheaper which is why i reccomended one.

The bodges that have been done to his HKS are not reversible, therefore he needs to replace his actuator.

I stand corrected. The extra info clarifies matters as the original post is misleading. That name Cal brings back some annoying memories...can't possibly be the same Cal I have in mind...

no my friend, Ive only been on here a few months I don't know many people on here
