3 Valver Q's + 1 v6 brakes/rear discs Q ! for experts ;)

[big_steve_x]

first, what accelerator cable should i use, astra or the normal nova one, i was told you can't get full throttle if you don't change the cable??? or is that a pile of brown stuff!?

second, the original car is a 1.2i, the engine used to cut out when i was cornering hard will it still happen on the valver as it was quite dangerous i think. somethin to do with swirl pots maybe, did the 1.2i have a swirl pot?

next i'm after fitting, water temp and oil temp gauges, how do i get the readings from the engine, do gauges normally come with fitting kits?

finally are the V6 veccy brakes (284mm drilled and grooved discs) big enough to stop my rear discs locking up!

any help would be great thanks!!!

I know the answer to one of the questions. You need the Astra accelerator cable.

Also with the brakes i'm hoping it will stop the rears locking up as i'm doing this next month, got my V6 fronts on already and rear discs ready to go on but mine is going to be stripped out so bit worried about the lack of weight over the rear end.

Best way to stop the rears locking is a brake bias valve, my bird has 288mm disks on the rear of her nova and it doesnt lock them up.

ive been told to fit 3/30 brake pressure regulators to stop it lock up

If you doubt your 1.2 fuel pump/tank set up, maybe swap the whole tank and lines for a Nova GTE one?

Brake biassing - if you fit brake biassing to a std Nova brake line set-up you will need 2 which will make it expensive and dangerous. Best thing to do in this case is to track down one of the rear lines where it goes into the master cylinder and blank it off. In the meantime feed in a replacement new line in place of the other rear line thru and into the cabin. Install a brake biass valve somewhere convenient and then "T" into the line after the biass valve so that you can get a feed to both rear brakes. I think Brett Warburton has this arrangement if you want to see how to do it properly.

Gauges - I'm not much good with electrics but all you should have to do is connect to the appropriate senders which should be already on the engine.
If you are using some sort of Vaux dash its just a case of finding the appropriate lines already in the loom.

CP would you not have to use the 2 outlets for the rear and join them first before it goes into the bias valve ?? as the standard system is horizontally split. if you did it that way it would be uneven as the one part of the master cyl is supplying one caliper and the other 3 calipers. or am i talkin shat ?? i suppose you could swap the lines on the master cyl so one outlet does both fronts and the other goes to the back via a bias valve ??

Only one I can answer is the brakes. They are 288mm not 284mm if genuine discs and are used to stop a V6 Vectra and I have them on "X". They'll easily stop you with an XE fitted. I could supply a new kit for ?250 if you're interested.

C.P thats the way i ran rear discs. blanked off one of the rears and ran a single back into a T piece.......but as i wondering at the time and found out since for sure this causes a slight brake imbalance.
The master cylinder causes the braking action to be done in a diagonal direction. i.e front left and rear right are together and vice versa. this means when you run both rears off the one line you are gonna have 3 wheels braking together and one front on its own.
To counter act this one of the front lines need to be blanked (the opposite one to the rear thats blanked) and the front ran from a T piece too.
This was done on the yellow and white rallycar at the show.
Hope this makes sence to y'all!!!

yes brian it makes sense. thats exactly what i said would happen.
