hey guys

got a series 1.5 r33 gtst.

i been told that the r32 gtst actuator is a direct swap for the 1 in the r33 as they are identical except the r33 actuator is 7psi and the r32 is 10psi.

my question is, by putting the 32 actuator in, i bypass the standard boost solenoid and just run a hose from the actuator to the intercooler nipple correct??

not sure what to do with the piping thats all? i remember when i got my car the solenoid wasnt working so we had it hooked up like this, just b/w actuator and pipe, but not sure if its the same now that i wanna run a different pressure actuator?

oh and for all those that are gonna say get an ebc or boost t, a) ebc too much $$$, b) boost t creeps

actuator will not creep unless spring is fcuked.

cheers

daniel

sweet thats what i was thinkin but wanted to confirm this.

im going in for a tune @ RE Customs in early august so will fit it when im there and have the safc2 tuned and timing checked to accomodate the extra boost.

You can by-pass the solenoid but it would be interesting to see someone keep it in the loop and run the 10psi and then up to 12psi after 4500rpm.

12psi should be OK on your turbo

I don't think anyone's done it yet so give it a go, and if you don't like it, it'll take you 3 mins to swap the tubes around to by-pass it as you originally intended.

Good luck

I've done it.

What happens is normally the r33 actuator is 4.5-6 psi without the bleed solenoid.

with the solenoid, it goes 7-9 psi (after 4500 rpm).

The reason why I gave a range is because mods affect the boost.

I've found the r32 actuator to be around 9-11psi without bleed solenoid

with the solenoid, it is around 12-12.5 psi (after 4500 rpm)

at the moment i have the standard solenoid grounded, so its constantly between 7-8psi. if i run the same wastegate will it be the same? i would think that it would still be restrictive...

dunno anyway ill see how i go, might run with just the hose to the cooler pipe, but then try that out with the standard solenid in line..

    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
    • Probably. I take it that they are also mentioned to be for R34 Skyline? For example.... RDA has that part as RDA7957. I have the dimpled and slotted version of that on my car https://www.ebay.com.au/itm/285518478694?srsltid=AfmBOopKxMuAFpsxZJdB1cam4D5RAj1f9yJyOttPZLAwXVNCOiwlhrIy This is DBA's top one piece equivalent https://www.ebay.com.au/itm/364246686631?srsltid=AfmBOorbb0XHQgqTvZLgQPhg70nqJtGvdojKnugum3O2LFSr2h-obp8D  
    • Ok i will get those 310mm. I found one but on a different site. This is the description on those...is it ok? Technical parameters: - Axle: front. - Disc type: ventilated. - Number of holes: 5. - Disc diameter: 310mm. - Total height with center: 54mm. - Thickness (new/min.): 30/28mm. - Designed for brake calipers manufacturer: Sumitomo.
