HOWTO: RB25DET High Boost mode with standard solenoid

[ZiiN]

thanks mate, where are u grounding it too? i dont have a multimeter to test whats a strong grounding point

[dezz]

I dont use it anymore because i've got a boost controller...but I had it grounded under the nut that holds something in that area on....it was bolted into the wheel well....also had it grounded underneath 1 of the airbox bolts and that worked fine as well

[ZiiN]

nice lil mod, makes them not feel so sluggish... good tempory thing untill can wind the boost up...

when i put a front mount on, i will also put a rb20 acutator on that i have here, do i still need to leave that grounded one i use the rb20 acuator or can i remove it?

[Buddy]

i just need some help with finding the solenoid? can some1 tell me where i can find it??

[dezz]

just behind/under the airbox

[Buddy]

is this it

[dezz]

yep

[Buddy]

so i just cut that black wire and eath the end coming from the solenoid

[dezz]

yep

[Buddy]

what should happen if i disconnect that plug on the rite of that pic?

[dezz]

not exactly sure, but your boost will be farked I beleive....

Once you have some form of boost controller, you'll be bypassing the standard solenoid, and then you can un plug that, and completely remove the solenoid itself without any drama

[Buddy]

i just cut the black wire and earthed it to the bolt just above the white wire in the picture but it is still boosting at 5? what have i done wrong

[dezz]

if you earthed the right end, it should be working

[Buddy]

i earthed the black end from the solenoid??

[dezz]

yep, it should be working, try grounding it somewhere else...might be a weak grounding point where you put it

[Buddy]

i just earthed it to the (-) on the battery and it is still boosting at 5? i dont no what i have done wrong??

also i am only using the gauge thats in the rpm to tell me what its boosting at, is that correct if this mod is done?

[Leeman]

hi guys, im interested in this mod as i seen this on a mates car today, will this still make a difference to my car with my profec specb11 boost controller on. i know this has a dual solonoid but am unsure if this mod will still make a difference?

I hope you're not waiting for it to hit +7 on the stock boost gauge, as thats not 7psi, but closer to 14....

If the mod has worked, the needle should be in the positive section, at about the half way line...so halfway between 0 and +7.

You need to test it on a nice straight where you can nail it to hit full boost, and make it past 4500rpm...if it doesnt increase boost at 4500rpm, then you're probably already hitting 7psi

[Buddy]

oh nuts!! u cant trust those car dealers!! he told me that it put out 7psi on that gauge thats y it had a 7 there!!

[dezz]

hehehe, if your gauge hits +7 and u have the stock turbo etc, it wouldn't be lasting to long
