id really appreciate a few questions being answered for me.. any help is better than where im at now.

1. when cornering fast, the "SLIP" light comes on in my r34gtt's dash, at roughly the same time, it feels like fuel is

cut to the engine and momentum is seriously halted, is this the same as the "TCS" off button? which doesnt seem

to stop it? how can i turn this off?

2. hicas light comes on every once in a while, doesnt seem to do anything though.. is this an issue?

3. turbosmart dual stage boost controller doesnt seem to change boost settings, i checked with a multimeter to see if the boost controller was getting the signal to change to high boost when i flick the rocket switch and it is, however boost always stays the same at 0.6 bar. i wound up the high setting a few notches and still no difference, anyone know what could be going on?

4. the tubosmart dsbc (above) is teed into the line between the turbo and wastegate, where it should be.. however

there is a second gated boost controller teed into the line between the intake manifold and a little electronic box

with "boost sender" written on it.. obviously this isnt going to effect boost, so why is it there? simpy to trick the

boost sender with a lower reading?

cheers for the help guys.

ive also just done an epic search and read up on the common slip/tcs problem and will see 666dan re: gizmo to turn tcs off automatically, however, when i press the tcs button, no "tcs off" light comes up on my dash, as it sounds like it should.. is this a problem with the switch or the tcs backlight?

also forgot to add question 5. perhaps the most worrying.

5. when im driving along in 1st, 2nd or 3rd gear and realease the throttle but still in gear, i get this loud scraping noise coming from waht seems like the lhs passenger door, its obviously a mechanical type noise and very hard to explain, like theres sand/gravel traveeling down exhaust after the turbo.. only happens on over-run though. does anyone know what this may be? completely goes away after i press throttle again..

Ok when u have NO TCS light up on ur cluster this means TCS ( Traction controll ) is enabled.... this means if u corner to hard... or slip by any chance.. the car will try help u correct it...to gain traction. this means that u will see SLIP SLIP flashing on ur cluster...

when u press ur TCS button and on ur cluster it says TCS off this means obviously traction controll is off meaning if u slip... its all up to u to gain traction u will not see the SLIP flash on ur cluster while TCS is off..

with respect to the button not working.. maby it is just light problems or maby the system is faulty.. ?

and that gravel noise neva herd anything like it... maby u got rocks in ur zorst lol ? i cant help u with that

cheers

start your car.. then press the tcs button.. even if your light isnt on leave it.. then go round your corners and see if traction control still kicking in.. if not then you can prob put it down to dead bulb.. but keep the fast corners off the road eh.. unless your a hero

what are you doing when the hicas comes on or is it just random?

hicas appears to be random, and no, heroics dont belong on streets im well aware of this.

went out last night to double check everything again, and it seems the tcs off button does work as does the backlight as it displays "tcs off" and no fuel cuts around corners.. so thats all sorted, i think i was just worried as im unfamiliar with these cars. however i know enough to know it needs new coils.

does anyone know about question 5? or has anyone experienced similar? i know its weird, but on over-run the car makes what sounds like a sharp buffeting noise from what sounds like the lhs? only at higher revs say above 3000rpm hence why it only seems to do it in 1st 2nd and 3rd..

has got me stumped.

leave the car in neutral and rev past 3k and have someone outside trace it down.. its hard for anyone to diagnose that over the internet without more detail/sound

      Mistakes were made, my R34 Story

      Yea the photos aren't the best. When I was pulling the bumper and headlights out there was a bodyshop guy looking on for it, there is a slight bend behind where the passenger headlight is, but we're talking a few MM and there is a little bit of a bend for the reo. That said it's supposedly well within the "Drill a hole in it and pull it out with a slide hammer to be close enough" and be on our way. The other option is to buy a GTR reo for the GTR bumper bits but this is a $2000+ fix for something Mr Hammer can probably do 99% of the job for and everything will/can line up pretty closely-to-good-enough.

      That's a write off for sure... Part out? 😛 I kid. It looks like the rad support has a minor minor bend in it too where the rep support sits near. Could just be the photos (and me not wearing my glasses right now). Worst case is you can buy a new radiator support, have it swapped over, and leave the car in paint jail for 12 to 18 months while you build the motor to handle twin turbos or a Harrop SC...

      It seems the definition of "Gregging" something might need to be expanded?

      R32 GTR - Where to begin

      By GTSBoy · Posted

      This is why I suggested that there is really nothing that can safely be done in the engine bay at this budget level. Just the work to reassure yourself that the engine won't instantly crap itself the moment the boost gets turned up will wear out the piggy bank long before the first turbo gets installed. Spend $10k and still not have any extra performance? My tip is a version of our standard advice from 15 years ago about buying a GTR, which is not to buy one unless you can afford to buy two. The new version is not to modify a GTR unless you have all the funds required to do it all at once, properly, and enough to rebuild it after it blows up.

      Oh, I forgot to mention this before.  It is accepted that your taking on risk buy turning up the power on a 30 year old stock motor. You can lower the risk with the ECU engine protection, but this is more money on sensors. CAN wideband, oil temp, oil pressure, coolant pressure, fuel pressure, air temp, etc. It adds up quick.  I am a huge fan of running all of the engine protection the ECU offers. You'll have to decide for yourself how you want the engine protection setup and what you think is worth monitoring.
