Hey people, need some help. i have a R32 gtst and i want to install a GTR diff in it, im planning on changing the whole rear end in one hit, now the problem is the gtr guards are pumped out more then the gtst ones so im presumeing it wont fit i.e tyres rubbing.

is it possible to put a negertive camber kit so the tyres fit?

Also there was a oil fillup inside the boot (presumeing its for the HICAS), my gtst does not have one of these instead i think you fill up the HICAS through the powersteering reservoiur, will i have to install this reservour into the boot of my car?

are the computers for the gtr and gtst universal?

The reservoir is for ATTESSA, so you don't need it.

ECUs are slightly different - GTR has 2 O2 sensors, and an air temp sensor, which the GTSt doesn't have.

The extra width in the guards of the GTR is to accommodate the smaller offset of the wheels. Your GTSt rims should still fit inside the guards.

thanks, so when you remove the hicas what do you do with the hydrolic lines do you join them together or block them off? if im not using the hicas will i still need to connect up the computers, or can i use the same ones, or am i going to have to buy a set to install,

If you are removing hicas, remove as much of the lines/solenoids as you can, and then join the lines together.

You won't need to install any computers as your car already has hicas (and it's associated computers) you will need a lock bar to replace the hicas rear steering.

      Steps to DIY sanding car back ready for respray....

      By GTSBoy · Posted

      When sanding across a convex panel, you need to sand, as much as possible, at right angles to the curve. If the panel is compound convex curved (ie curved in both directions) then you are SOL and have to use "craftsmanship" to get it right.

      Duncan's V37.......race car?

      This sounds like me. And then why I leave shit that I had previously hobbled together broken. Lately I've changed strategies to "If I don't want to justify the money on decent stuff, I'm not going to justify hobbling it together". I'm still for DIY, but DIY it properly is more my thing. However, I am terrible on not setting up backups still... Which reminds me, I need to go backup some of my work VM machines... Oh, it's also why I've become a lover of building things into Docker Containers... Then I just need a machine that can run docker, and bam, that specific system is up and running, on the specific versions of everything I need for it to run (In the event a change in required software version breaks something else). Also, these days, my steep learning curves are spent with work related stuff, and on very varied projects, that my want to do other random projects like build a dashboard for my own car has dwindled away to "I just want the car running", which is my current PITA, as I'm getting the Landcruiser usable again, and it has just been non-stop the past 6 to 8 weeks of buying parts, and working on it. Oh, and tools that are meant to be fit for purpose... And they break, because 25 year old 4WD decides it's stronger... But by the time I have it ready to roll back out the drive way, nearly all the stuff in it will have been touched and serviced, so the damn thing better give me NO FREAKING ISSUES, for at least the next 50,000KMs! Just redone whole front of the motor, and resealed the up top stuff, replaced a bunch of things getting perished, new timing belt done, water pump, lower timing cover (Toyota diesel engine runs timing GEARS for the bottom half the motor, and a timing belt from halfway up to the top), new harmonic balancer, fix up the alternator, new thermostat, full swivel hub rebuild, new bearings and seals front and back, steering box rebuild, new battery, and today, it turns out a rear shock has let go, so four new shocks are about to go on order, and that will leave me with after the next run of work, to see if I need to order just a brake caliper re-seal, or if I'll need new pistons in them too. Oh, and I'll finish welding in the new floor sheet metal shortly too. Presently I just want it finished already... But once all the above is done, I still need to fully service diffs, gearbox, transfer, and motor. Then flush and bleed the clutch, and flush and bleed the brakes. But enough about our waffle, back to Duncan's heat problems... I think for Duncan he just gets a thermoswitch, and a manual switch to run some water misters. Thermo so it's only on above certain temps, and the manual switch so it can be turned off even if it is above certain temperatures. IE, switch on for "I'm now on track", then it doesn't need any "smart" computers that might try and do things wrong. And switch the thing off completely on the cool down lap, so when he stops in pits, there's not even a possibility of it dripping any water out to get him in trouble.

      So I ran into the same problem. I got stuck in the cycle of again of putting putty sanding it, putting putty sanding it, because of a low spot. And notice my block is not completely flat with the panel, even though it's a long block. My panel is slightly curved. Is this an issue? Do I need something that matches the door perfectly, or no?    I do have the smaller flexible block that covers the width of the repair just not the length, I was experimenting with it again to but seems to be the same issue
