Hks Actuator For R33 Turbo?

[sly32]

hey,

i can get a HKS acutator delivered from japan for $140, just wondering is it worth putting that onto the turbo, i bought this rb25 turbo for my rb20 and doesnt have one so i just saw the hks 1 and was wondering what people think about them,

cheers JV

There pretty good but the max boost you would probably run on your RB25 turbo is about 15psi so no point IMO

Your RB20 actuator runs 10psi stock, with a cooler and exhaust and maybe because you have a larger flowing turbo it may bleed out to 13psi - which my RB20 turbo did with cooler and exhaust so an RB25 turbo with RB20 actuators shouldn't have much problems doing the same

Just get a bleed valve and set it to 14psi or so and get it tuned - You will save an easy $100

Also one of my friends had RB25 turbo on his RB20 with turbo back exhaust and cooler with remap - it ran 14 psi with no boost controller
