R34 Boost - Turbo Pressure Question

[pear]

Hi Guys,

Think this relates to the “Tutorial / DIY / FAQ”

HOWTO: RB25DET High Boost mode with standard solenoid??? But blocking pipes instead of cutting wires.

I’m very new to this and could be miles off track!!

The car – R34 GTT (S1).

The main mod that I know about is a 3” pipe turbo back. Originally it had no cat, but there’s one there now - not high flow at this stage.

It seems to be running ok, but as I haven't driven may other skylines on the open road, I don't have much to compare it to...

Can you check out there photos and tell me what’s going on? Any + or – this will have, etc…

I'm having trouble uploading pics, but here's the attachments for now;

Location of blocked pipes

1 - Turbo pressure control solenoid?? Boost control solenoid

2 - Turbo pressure sensor

Thanks for your time,

PEAR

forgot to add, the standard boost gauge seems to be working.

boosting to approx +.5 or a bit more. I think that's normal for a stock R34 GTT

any ideas???

anyone else have these pipes blocked?

I've tried searching but can't seem to find much on this.

bro

i just used one of those $35 manual boost controllers currently being sold by turbotech. check for sale forums,, they r pretty good - used it to get rid of wastegate creep

anywho,, that seemed to work for me,, sitting on 10psi at the moment,,

didn't have to do much,, just had to block off one hose after installing it,,

i'll be in brisy this weekend if u wana check out my setup,,

btw , urs is a Series II

my boost always ran halfway between 0.5 and 1 on the stock gauge (even before i installed the boost controller)- and thats 10 psi (used aftermarket boost guage to check) , i only have 3" turbo back exhaust and k&n panel filter,,

Hey Afro,

thanks for the reply!!

will give you a call/pm to catch up.

still seems strange I have 3 pipes blocked.

I was wondering if it once had an aftermarket boost controller, when removing it they just blocked the pipes.

I've been told a turbo timer was once installed and had been removed before i got it.

search the forum for 'Turbo pressure sensor' and didn't find much.

especially couldn't find anyone blocking them.

still a mystery, unless anyone else has any ideas?

Afro, will talk soon

Cheers

ya i'd say you used to have a boost controller in there,,

unless the other turbo timer used to have boost pressure display on it,, i.e. would need a boost pressure signal..

lol

choy,, i havent seen pears setup yet,, me still in melb!! but coming back for this weekend,, and back to melb on monday,,,

[AFRO]

pear,, might be a good idea to alteast re-fit the hose for the turbo pressure sensor,,

the boost solenoid hoses should be fine for now,,
