Hi,

i just bought a R33 SII 97 GTS-t and i have noticed that on the internal stock boost gauge that it never reaches +7 psi.

The car is in stock condition, as far as i can tell, but it does look like it has been detuned by the old fart that had it before.

How can i tell if i'm running 4 pound or 7 pound amd if it is running 4, how can i make it 7?

Any ideas

Factory boost guage isn't in psi...  It's in mmHg...

 

Use an online conversion utility if you want to be exact but it's roughly half...

Hi,

I wonder if anyone could enlighten me what caused my factory boost gauge to shoot up to +7 when I switch on the ignition. I had been having this problem for some time now. I suspect it's something to do with the wiring as I ended up changing a second hand auto-transmission trying to solve the problem of gear not shifting correctly but to no avail. The car will start on 1st gear on D but will not change gear unless I rev it to 4000rpm or more. However once in a while, the boost gauge reading will return to normal(ie around 0 boost when the ignition is turned on) and the gear will change very smoothly and engage 2nd gear at about 1500rpm and 3rd gear at around 2200rpm.

Any views or assistance appreciated.

      I have to put something here in order to post the photos. From what I could gather there's more enthusiasm for modified cars now than there has been for years. There were probably more younger people there than older (me included lol) which was a good sign.  It did seem like the record least amount of representation of the 90's era hero cars on display though. Like maybe one or two examples of S-chassis Nissans, and maybe 3 or 4 R-chassis. By comparison there were a lot of Civics from that era but in all there were about 10 - 12 EG/EK Civic Type R.  Euro exotics are always there in large numbers, led by Liberty Walk...... say what you will about kids using markers to scribble on a Ferrari F40, it did seem like a stunt to infuriate Ferrari enthusiasts, or Ferrari itself. I wonder if there's something more to it. Either way LBWK have done some heinous things to a Lamborghini Miura this time. They should stop now.

      Engines and drivelines are not war stoppers for me mate, busted arse bodies and un-obtainium parts and panels are though Both cheap Brumbies I looked at had trashed tubs and a fair bit of rust

      Stock O2 sensors are narrowband. They're useless once you're away from stoich. IE, useless for what you're trying to do. 10:1 will read the same as 14:1 from the stock O2 sensors. That is, they'll read rich. The same level of rich.

      I agree once misfires happen it's basically worthless, but the hope is you can see what's happening in the run up to that.

      You should totally get a Brumby, and then come pick up the Subaru Liberty GTB I have here. EJ25 Turbo, 6 speed manual from the sti (just no dccd), and the good rear diff. Drop all that into a Brumby and go have fun!
