Two stage boost removal just done it :-)
Two stage boost removal just done it :-)
My Skyline has the two stage boost system (think most RB25 skylines have?) and it usually runs around 0.5bar up to 4500-5000rpm then goes up to 0.7/0.8bar upto 7000+rpm,
This little mod removes the 2 stage boost part and gives you the higher 0.7/0.8bar of boost all the time so more power all the way through the rev range :thumbup1:
it ups the pressure from about 7.25psi to 11.6psi approx, so about 4.35psi more pressure?
Very simple to do as it only takes 1 wire from the boost solenoid which you ground out to the body of the car, I've just done it and have only earthed it out but on Wednesday i'll be fitting a switch in the dash, so that i have the choice of running 2 stage boost for normal driving or single stage for a bit more fun. (always be on single knowing me:laugh
:thumbup:Connector block on the solenoid earth wire..blue earth wire can just be seen under the solenoid?
(will be nice and tidy when i redo it?)

And how i'll be wiring the switch in on Wednesday..to give you an idea of how simple this mod is?

Hopefully fit it here like this chap has?

Will try and do a "how to" when i re-wire it and add the switch and take a few more pic's?
Simple and free to do if you have a bit of wire and a switch, giving you better boost all through the rev range and a choice between 2 stage and single stage :thumbup1:

Been meaning to do this for a while now so thought i'd sort it out at last, Its a very simple mod and another freebie but does seem to make a difference to the car and how it goes? :tongue_smilie:

IS200 Turbo project now just about complete ! See my thread here and leave your comments.
Now running standalone Syvecs ECU and no stock ECU !

The main reason i've done it is because my solenoid seems to make it up as it goes along, I could really do with a new one because it usually sticks at the 0.5 bar setting all the way through the rev range, so to have 0.7/0.8 bar should be a lot more fun :w00t:

How have you found the 0.7/.08bar boost all through the range?

13-07-2016, 10:22 AM #4Sounds good and looks so simple too :thumbup1: Gotta be a must have performance mod for the RB25 users eh.

On the private road i've just been down
i can usually hit around 125mph in 4th before i have to brake, i've just hit 140+ in the same space (had to use 5th gear) so i'm well impressed and it now feels like a skyline :thumbup1:For a comparison its like when you 1st fit a supercharger to an IS200, It picks up great and puts a huge smile on your face

Just been for a blast and got to say it works to great effect :w00t: the pick up all the way through is fantastic, enough to make your legs shake with excitement :laugh:

If the turbo does go, you can see them quite often on ebay or on the owners clubs for less than £100, so its not too bad unless i want to upgrade and go bigger, then it costs quite a bit more?

The turbo should be fine mate, they say dont take it above 0.85-0.9bar on the standard turbo? some guys run theres at 1bar and still havn't had any problems so running 0.7-0.8bar should be fine :thumbup1:

I've not taken anybody for a spin yet and be good to have another point of view on how it goes

Might have to do a test flight with a couple of you guys while were at JAE to see what you think of it?
