Hi guys, im getting a pair of HKS GT-ss for my car, the thing is that it comes with garett 2860-5 actuators...

i read that the GT-ss and 2860-7 are the same turbos

my question is:

would 2860-5 actuators be compatible?? as the GT-ss are smaller turbos compared to the 2860-5

thanks guys

thanks for clearing it up guys

Garrett ones would be, HKS might be a tad higher as a base pressure. Not sure on that one

im not sure what you mean with this one,

are u saying HKS actuator has stronger spring hence = higher base pressure?

anyone knows how many psi HKS and Garett actuator good for, or are they adjustable?? never seen one before excuse the noobness

HKS actuator is suppose to be 50% stronger over standard therefore allowing you to wind up the boost and holding onto that boost when needed. IMO if your not going for crazy boost e.g over 1.4 bar i would not bother. spend money else where.

We just did this with some 2860r-7's, was told the Garret 2860r-5 actuators open at 16psi and I believe the HKS actuators open around 15psi (my GT-SS's arrived this week muhaha)

Both actuators have the threaded arm, so you can adjust the reach - so yep they are adjustable.

Edit: They are good for whatever as long as it is over the base pressure (so 16psi+ or 15psi+). Just depends how much air you bleed of the line that connects to the actuator - leave this disconnected and they might just never open. The turbo however, will break...

    • Well, the NA RB25 is nothing special in terms of the amount of power it makes stock, nor with any easy mods like extractors & exhaust, opening up the intake tract, etc, etc. And just like any small capacity NA engine, getting lots of power out of them takes a fair bit of money and, depending on how far you go with big cams and high compression and so on, quite grumpy to drive. So, boost is the answer. Many many many of them have had a turbo added. This is easy enough. Same as for any engine. Need the things you need to bolt on the turbo of choice, fuel system and management upgrades, clutch, stronger gearbox ( you do not want to run a boost RB25 through the NA box), diff, brakes, etc, etc, same as you would for most other NA+T things. Some much smaller number have had a supercharger added instead. These are good and cool, but have nowhere near the potential of the turbo route. All the same required upgrades apply. So, potential? Anywhere from not much to quite a lot, depending on how much effort and expense you want to go to. Is there value in the effort and expense? Objectively, no, there is not. If you're gaining enjoyment and don't mind blowing a lot of money on the project, then that's where the value is. Parts? Nissan dealers for some. Many many on-line vendors who do Japanese manufacturer spares (buy buying them from disposals at dealers around the world, direct from manufacturers, increasingly from Chinese knockoffs, etc) and warehousing them in Dubai or similar places. Amayama, Partsouk, etc etc. There are quite a few. Some local to Australia, some local to Europe, some local to the US. You can upgrade literally everything. For an NA, unless you're going to boost it, there's little point going past a nice exhaust, as I said above. After that (well, actually probably even before that) you should concentrate on making it handle the best it can, good brake components, light wheels and tyres, and just make it something to enjoy throwing through the curves. You'll never, ever win any drag races, so it needs to be taken as a nice point-to-point car. Throw in some Recaros or Brides, nice Momo wheel and gearknob, so it's pleasant to be in (because god knows, the inside of an R33 is not a pretty place!!) and away you go.
    • How many $$$ do you have to slip cams to logbook a car that’s not the orginal to the 1990 standard lol
    • Thanks for the update I truly appreciate it. I was trying to figure out the sensors. 
    • My son recently purchased a 93 Skyline GTS25 (NA), I am hoping to get some insight as to what potential this car has.  I have auto mechanical experience, and I am capable of working on this vehicle, but I know nothing about it.  Where's the best site to purchase parts (maintenance, repair, upgrades)? What kind of upgrades are available?  Thanks again and I look forward to any information that you all have to offer!   Darrick
