I'm looking for an actuator to fit my t28 that can hold 22psi of boostpref without the need to use a bleed valve. I have an actuator rated for 22psi that came with a t2/25 but it can't hold 1bar with a bleed valve on the t28
looking for something cheap and readily available, what you guys suggest was thinking a garret -31 or -34 will they be up to the job?
yes
Without a bleed valve?
what about a 21 turbo actuator??
-31, no problem.
Great cheers guys.
Gary let me know what you come up with, you always find a bargin

Not yet, probably going to stick with the t2 for now, the car does what i wanted it to, its still quick to 100 mph.
I need a spin out in a b18 5 with the bigger turbo really to see if its what i fancy.
How is yours running Gary, i take it you have had fueling problems, how does it feel with the t28?
yeah its running fine at the moi have got the fueling pretty good but still a bit rich but with the nature of tricking the maf with a hole in the inlet pipe its never going to be spot on. I thought mine went really well at 18psi with a t2/25 and was a lot nicer to drive on the road and off boost driving but the straight line grunt of the t28 is ace
Try a -34. My -31 wont hold more than 18 psi without bleeding off.
Think im going to invest in a -34 to, i have my boost controller set to the max to bleed off at 90% duty cycle and its just getting 18psi, james a while back said i probably have a very weak standard actuator.
Might as well buy the -34 for if i decide to go for a t28 or gt28
Pleased your car is going well Gary, sounds like the t28 is more for a quick squirt down the straights, not for on track.
The t28 spools really well I get full boost at the same time I would with my old t2/25 and now it pulls strong all the way up the rev range. Spool is prob helped by a 3" elbow/dpi I have fitted now. I have yet to take it out on track but I think it will work well, its just if you want to crawl along at slight throttle it judders about a bit but as soon as you plant your foot its sorted.

Your car is going to be sat in the garage for years mate, get ya finger out, once you have a house, kids etc car time is practically non existent, trust meYou'll change to t28 when I sort out my r5gtt!

did you have the downpipe made up? if so who made it if you dont mind me asking. also is your t28 mounted behind the engine or have you got one of those prima type manifolds?
cheers
my turbo sits in the same place as on the c1j big jim made a log manifold for me. Think it was ashy put a bms downpipe on ebay with a t28 flange and 3" down to 2.5" so i bought it
Only prob with moving the turbo is getting the maf away from the turbo far enough so the holes you cut in the inlet pipe to trick the maf dont mess with it
yeah me old mucker right shame thatShame ya live the reet doon sooth
