HOWTO: RB25DET High Boost mode with standard solenoid

[Got a Pulsar]

I think you might be confusing the actuator and the Solenoid.

The actuator is doing something and is required to open the wastegate. The solenoid is what you earthed.

Removing the Solenoid will undo this mod and give less Maximum boost.

Hey guys I just got my 2nd solenoid just wanted to know where/how everyone Is fixing them pics would be best but any help well be great

[Got a Pulsar]

I just doubled them up on the bracket.

[madman_rocks]

I have been trying to take it off the stand thing but mine are on there tight

[Got a Pulsar]

Then more weet bix are required.

[madman_rocks]

Lol got just had to try a new tool

Quick question

Is this mod pointless if i am going to be putting a boost controller in my R33 or should i do it so it sits at 7psi down low then the admired 11-12psi in the top end from the boost controller? I want to run 7psi down low and 11 or 12 top end.

Cheers

R33 turbo has 5psi waste gate spring. The solenoid bleeds it to 7 or whatever the max pressure is set from factory. Boost controller will essentially bypass/replace the solenoid.

Awesome thanks for the easy answer. I realised boost controller would replace it after i went out and looked at the solenoid today. My mistake

Why on earth would you want to run lower boost down low? That's heaps pointless.

I'm sure Nissan can answer this as they did it from factory...

[niZmO_Man]

Make the auto transmission last longer is my guess.

[wc34_fd3s]

So I'm assuming this works with rb25 neo in my stag. I've got a boost t will that effect this mod? Because I feel a massive gain in boost once over around 4000rpm...

Any help appreciated guys. Cheers.

[wc34_fd3s]

Stag is auto buy the way.

[Got a Pulsar]

If the Stock Solenoid is there and connected and you are feeling a Boost increase at 4-4500rpm then yes.

If you earth it, you will get that Extra Boost Always.

[wc34_fd3s]

Thanks man, so it's the black or white wire for the stagea?

And will this contribute to making my turbo shit itself?

for the quick reply!

[Got a Pulsar]

Should be the Black wire but I can't be sure.

What Boost PSI do you currently get using the Boost T once you're over 4500rpm?

[wc34_fd3s]

10psi

[Got a Pulsar]

Should be OK but you could just wind in some more Boost with the T and eliminate the Solenoid completely.

In theory 10psi should be in the safe zone for the turbo but there's too many variables and Luck to be sure it's ok.

Could blow on 7psi, could last years on 12psi... Who Knows? Fingers crossed.

[wc34_fd3s]

The more boost I wind, the scarier it becomes haha, I'll try the mood tomorrow.
