How to, PROPER RWD conversion, someone done it before?

[Caleb 895/1000]

Im about to head into the mines and have decided to start a project toy, I have been concidering waiting and buying an Sti BRZ however could proberly not justify spending that much just for a track hack.

I know people weld the centre diff to make the wrx (GC8) RWD, but i cannot find anywhere how to do it properly? my understanding is a 6 speed box is the strongest and a R180 diff compliments it well.

Before anyone hates on me about doing this to a rex, i want to do it properly and not ruin the car, people will ask why... because I want a RWD and I need a Subaru, and $60-70k for an Sti BRZ is far too much to drive it a few times a year.

Any ideas or help would be much appreciated, I would be hoping to put around 250-300rwkw too.

^ Yes I did see that, I said i wanted it done properly not just hori style welding the centre diff. It pays to read the whole post before being cheeky lol

I was also wondering if there was a different way to do it rather than welding the centre diff

buy a Nissan?

totes cereal post btw [even turned caps off]

BLAZD may or may not know quite a few secrets/has a serious RWD setup

there was also something I vaguely remember where you can buy a piece to swap in for the bit you weld : like a solid locking ring, does the same etc.

anyway the welds are the last thing to break, never heard or anyone moaning about that part of the conversion

It seems to be only for the 6MT not the 5MT, I stand by my how too, bang for your buck it is WIN, but hey if you can get a diff replacement for your trans then do that gotta be less weight

just weld it . other stuff will break so youll need to save the $$$$

It\'s only hory if people can see it; when\'s the last time someone looked in your gearbox and said, " haha you\'re still running stock synchros\' never, yep that\'s right; never.

Sweet! Cheers for the help, food for thought!

[lachlan]

use a big (Arc) welder . have seen the aftermath of a failed attempt at welding a diff . spider gears chewing up weld :-\

you know where a centre diff is aye ? in the section you take off the rear of the g box

[slydog]

Go to geartec in palmy they have a tube that replaces the diff around $700 if I remember

Get a locking spool if you\'re against welding it.

But if you\'re only driving it a few times a year you may as well just weld it?

If it\'s a track hack you\'ll be better going r200 or replacing r160\'s because fuck having to replace r180\'s (yes you will break r180\'s)

subaru\'s are shit for lock you\'re going to need some modifications to the knuckles/tie rods. You will also need a lot of caster angle as subaru\'s once again don\'t have much.

Can be just as good as any other rwd with money spent in the right places
