So I've dropped hints that i was building a new car instead of taking the drag car back to Albany for next year, however If i can't sort my shit out with this in time, I will be taking it again.
So i conned you into clicking this page because of the GTR label... but it'll be worth it. keep reading.
So what am i doing? instead of converting my drag car to AWD, which was the plan. I Picked up a silver vy sv8 rolling shell with vz bonnet/guards/lights on a set of 19" GTS rims a couple of weekends ago, for the lowely sum of $1k
Today i stripped all the carpet, seats and shit out of it, along with nearly a kg of rat shit from the bastards eating the carpet/plastics.
Motor wise, I'll be using the drag car motor, it's a 410ci LS2 darton sleeved block, it was pulled out after the end of the season to check it over, rod bearings were still like new so we put it back together.
As the motor was assembled over 5 years ago, I wanted to put new valve springs on & it turns out it was a good idea, as we did find one of the inner valve springs broken on a valve (triple valve springs) so got all double's put on. Much smaller/lighter then the older ones that were available back then.
Not sure how long it had been broken for though
Anyway to run the AWD setup, I'm using an Adventra front K-Frame which is a bit on the beefy/heavy side compared to a normal k-frame, had all new nolathane bushes installed in it through out.
As the sump is a much better design I won't need to run an accumulator any more (look very gtr'ish?)
The front diff bolts to the sump, with a driveshaft going through sump to the front axles, the front diff does not run an LSD though. On the AWD commodore platform the ABS system controlled wheelspin from wheel to wheel with no LSD's at all. I wont have that shit.
I'll just run a locker in the ass end and let the front tyres spin, apparently they tend to light up the left side so we shall see.
Transfer case wise I'm using the standard Adventra NV120 transfer case, it's a 38/62 split. Gearbox wise I'm going to use a VE TR6060 geabox, but i might change the 5th gear ratio from the original .84 to a .80 from an earlier box.
Now transfer case to gearbox is where shit get's interesting/fun trying to work out & i've been getting help from a guy who does a heap of offroad 4wd stuff. Basically I wanted to have the option to run the car in AWD & RWD for dyno tuning & in case something happens to the transfer case (they weren't really designed for my power)
So we did this by making up a new "spud shaft" that will bolt into the standard rubber donut on the gearbox & then slides into the transfer case, we will then clock the transfer case for the front drive shaft once i get all the motor and shit in. If we need to cut out the tunnel to fit it, that'll happen & was the main reason i was doing this build in a new shell & not my drag car.
That's were i got up to today, tomorrow I'll continue on removing all the old aircon blower/heater core. I'm going to leave all the original wiring in this car though as there is really fuck all to remove in the first place. I may even leave the front speakers in for some doof doof.
I'll update with pics/findings as I go.
Dave
