Dual Wastegate Settings

[MYRB30]

Hi all,

To cut along story short I've fitted some turbos to my GTR (I didn't look at the part number, I just fitted them), I noticed when I went to fit them that the rod on the waste gate had two settings, so I set them on the lower boost setting, but on the road I had only 4-5PSI at full boost (Not cool in a GTR, my VL turbo would have killed it).

So I changed the wastegate rods to the second hole (higher boost pressure), but the thing has way too much boost (Like i get scared and back off at 18 PSI).

Has any one had any experience with this sort of thing? Im hoping someone can help me out as I really dont want to have to change the wastegate actuators, cos that looks like a really quick 2 minute job (NOT).

Thanks guys

cheat and fit a bleeder to the 4psi setup

post a pic of the actuators.

What turbos?

What actuators?

You sound like a VL owner - lazy and stupid!! So you dont know what turbo's you fitted and you have no idea what the actuators are for - cause they dont sound like anything I've heard of. f**k if you barstardised your GTR I can only imagine what the VL looks like!!

You sound like a typical rice owner. You ever got the numbers off a turbo whilst on a GTR engine???? The Rego departments wont even do it.

Look here, I asked for help to save myself some work trying to get these numbers. I actually got these turbos off a GTR that had spun a bearing.

I know what the actuators are for d$#%%@$d. And if youve never heard anything like them, then your stupid. F%$#&g stupid. Seeing your a w@#$%r I can only imagine how your palm looks. Get out of this thread please!!!!!!!

Uras, and R31nismoid, thanks for your replies. The turbos appeared standard, same cover and housing.

Iĺl hunt around for a picture if you like. But the turbos looked identical to what I removed. These type of actuator appears on turbos for sale now and then, I was hoping someone has had some experience with them.

Turbo covers might be the same, but a number of aftermarket ones use identical covers... so you could have any given number of turbos.

You need the ID tag numbers to be 100% sure.

Thanks R31nismoid, I appreciate that.

I wish my turbos would push out more than 18PSi when the intake settles down across the power curve. what are they?

Mine are fudged N1's, but fail to push higher now.

Let us know what they are will u, I want to keep the twins, but need more pressure now.

Sorry to almost hijack, but u have the total opposite of what I am experiencing.

Remember that pressure can also be a restriction to flow across the head as well, and it could be an indication in the intake side, but only there.

[R31Nismoid]

What do you mean fudged N1's?

With good actuators and boost control 20+psi is easy for those

[Richieb]

Nope. Climbs initially to 23psi, and then tails off to 17psi as the revs get higher.

Mine are running at 100%... flat out now, controller is the best dual, and the actuators must be working, as I can lower the boost via it.

Even the sensors say pressure is dropping off.

unless...

Alright, Ill post back here when I find the part number. Theyŕe off a R32 GTR that was imported for race use, but the motor was knocking so the vehicle was stripped.

Has anyone else had to get GTR turbo numbers off turbos whilst in the car??? Last time I tried I could see the front turbo number, but it didn have air con so was a bit easier, still a bitch to see thou

[Richieb]

I have some photos of the orig turbos I took off my R32, I'll have a look to see what they say for ya.

[MYRB30]

I checked the turbo part numbers and they are stock r32 gtr turbos. I also checked what pressure the waste gates are opening, and it's at around 9psi on the high setting so I must have an issue with the boost solenoid or the hoses.
