couple of questions

alxlaw · July 05, 2009, 03:55:15 PM

im the proud owner of petes old cab, really pleased with it just a couple of little things that irritate me -

1: when i brake coming off a motorway it feels like the car slides over its subframe or asif the lower wishbone bushes have worn away (had a caliba did the same thing) is this common? if so where are we buying said bushes/ wishbones?

2.its developed a random intermittent warning buzzer i can only assume means something, however its not accompanied by a dash light or any high/low readings on gauges... any clues??

3.my eyes burn when i drive lol and it constantly smells of petrol?

4.apexi boost controller only boosts to 2/3rds of what you set it too is this normal?

its being sent to pip at WGT in middlewhich for a full set up and fettle hopefully they can resolve a few things

im still chuffed with it tho!!

Don\'t know about

1) - that seems very strange - but it could be a lose bush I suppose.

As for

2) Warning Buzzer - it could be coolant level - check the expansion tank is at the correct level, and check the radiator cap is on properly. The system should pressurize and if extra water is needed, it should be drawn in from the tank. There should be a warning light for that - but the bulb may have blown. Buzzer comes on for that and something else if I remember correctly.

3) If it\'s running really rich on idle then you\'ll have \'burning fumes\' at the rear - a good tune up should fix that.

4) Seems odd - could be a boost leak on one of the intercooler hoses.

Could the buzzer be the rev warning buzzer when you are at the redline?

cheers prof, i hope WGT will give it a good fettle from what i heard there pretty epic!

(m1tch - lol!! no its on when i start the car and stays on for about 4 mins..... which is becoming almost intolerable)

That sounds like coolant. You can do a quick check for this actually. Before you start the car, locate the water level sensor on top of the rad, follow the wire back from the sensor to the connector. Unplug this and earth the wire that goes to the instruments. Start the car - if the buzzer isn\'t sounding anymore, then the coolant level is a little low.

are you usually cornering at the same time? if so it could be the rear steer bushes are knackered

nice one, ill give that a whirl

so you own Petes white cab then

alxlaw · July 06, 2009, 11:38:27 AM

no its in a strait line when braking hard off a slip road - rear steer??? whu?? is that why it feels like it has the most open diff in the world?....need the rear steer killing in that case any clues as to how i go about that? my 300 had a hicas lock bar same solution for the fc\'s?

grinder · July 06, 2009, 11:40:41 AM

its worth checking ther DTSS - have a look in the 2nd gen section - there is a recent post about it

it should eliminate the rear wheel steer completly

looks very interesting need to get my head under the back of the car, i cant get my head round how bushes will null the rear steer (that i didn\'t even know i had till 5 mins ago lol!) do fc\'s have lsd\'s as standard if so are they 1 way or 2 way? anyone got any decent pics of the underside, is it passive at speed this rear steer? can it not be nulled by locking hydrolic lines? or is it even a hydrolic system? i don\'t know enough about this car yet, its very similar to the 300 in many ways yet completely different in others

dthebuk · July 06, 2009, 12:41:04 PM

if you have an LSD then you\'ve either got an aftermarket diff or a very special FC. The cheapest option is probably to get the diff welded, or you could buy an FD diff as they fit in the TII diff casing.

The rear steer is passive unlike nissans HICAS, therefore its usually eliminated by these bushes. I supose you could probably fit some kind of arms to stop it steering, but that\'d be totally custom, and most likely harder

The rear steer is passive - it\'s basically some bushes that give under a certain load, so they will throw you into a corner with a bit of oversteer and then lock up. Some people hate it, but once you are used to it, it\'s quite easy to predict.

The DTSS bush kit eliminates the passive steer function with a solid bush that has no give.
