Hello

I am putting a RB25 turbo on to my RB20 engine. The Rb25 turbo has a HKS acuator on it. Does any know what this does for the turbo? I have read that I should put my RB 20 one on to the RB25 turbo, but should I keep the HKS one on their when I put it on to my engine?

Help please Thanks

mmmm...this could very well be a 14psi actuator...as most hks actuators are....what amount of boost do you plan on running and what modifications other then the turbo do you have to support these???

i will tell you now with an actuator set at 14psi you wont get any spiking or weird boost creep...it will be smooth and throughout your rev range.

And very dangerous to the lifespan of the turbo. Stock rb25 turbos are renown for blowing at more than 12 psi.

ran my rb25 turbo on 15psi daily.. never blew up and no shaft play :laugh: made 206kw

hks actuators are a very good application for an internal gate turbo, just adjust it down to around 11 to 13psi with a good tune.

got the same setup on our silvia, rb20... 25 turbo and hks actuator

just adjust the actuator to what reads about 14-15psi and no need for boost controller :ermm:

I am putting this, downpipe, split front pipe, hi flow cat, onto the car. I was planning on buying a boost controller. So far , everyone says put the RB20 actuator onto the RB25 turbo.

If its going to shorten the life of the turbo I will take it off.

Keep or take off?

      The issue now is the 'fuel cut' while driving, and when it happend, it does not stall. This, I did not test the fuel pressure while driving as I cannot with a fuel pressure gauge. I do have Nistune logs, yes. I have also replaced the MAF Sensor.   Also related to the FPG Fuel Hanger – I just realized that I need a Deutsch Crimp Tool to crimp some cables for the FPG Fuel Hanger. Need to purchase additional cables as the kit only included 2, which are for the float. FPG has not responded to my emails so far since purchasing. I thought about taking it to someone and having it done professionally, but I am reluctant since everyone I took it to messed up in some way.

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      R33 GTR running -9 with no tune

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋
