Default rwd conversion

I've heard that we can convert a impreza to rear wheel drive... Is it true?? I'm asking because down here in Puerto Rico we don't have a awd dyno and I gathering info about this rwd conversion to see if it is true and I can do it so I can do some dyno runs and know my wheel horse power...please help me

They did this in an article of Sport Compact Car I think. Basically they installed a custom made center differential that only outputs power to the rear.

A company in Australia makes a custom center diff replacement for about $400 that makes your subaru into a RWD vehicle.

I believe many Subarus with an automatic have a fuse you can pull which makes them front wheel drive...of course this won't help you if you have a manual box.

Hmmm...400 for RWD, that would be cool

Too bad the rear dif isnt that big so it would take alot of strain holding all the HP instead of just 1/2

Lets not forget installation to put that thing in and then revert you back to AWD. It could get very pricey. Better to just buy a spare tranny and keep it in RWD configuration.

Why not buy a turbo RX7 if you guys are thinking about RWD. Subaru is meant for AWD, so use it.

The RWD conversion product I posted posted is for tuning purposes only. It is a great alternative to road tuning and when you only have 2WD dyno's near you.

Besides you love your subaru too much, AWD is not the end all drivetrain setup.

teiva-boy, I completely agree, Ive allways been interested in how it would be to have a rwd RS, and have "thought" about doing it.

where can I find tech info on the how to of the conversion? my front axles took a dump on my daily driver awd impreza and according to sport compact car, it is very cheap to do this. my specific questions relate to the removal of the front axles. will I have to create a custom cover and seal system for the hole left in the tranny? or can I just remove them and be okay? same for the hubs? And I know I need to weld the spider gears, and that they are reletively easy to get to, but exactly where do I need to weld, or does it even matter? Pics would be a huge plus. I know that this is the ghetto way, but w/ 175K+ miles this car is on it's way out, and I don't want to spend any more dough than i have to. this is on a totally stock 2.2L, 4spd. auto, it is not for drifting or anything silly. It just has to get me around for a little while longer on the cheap. Thanks in advance for any info you all can provide. Now back to the hunt for more info.....

there have been lots of posts about that drift car. the radiator is in the back seat


but if i were to do a RWD setup it would be to reduce drivetrain loss and be unique. how much drivetrain loss does this get rid of?

-update-

I couldn't find any info on how do do this conversion at all, so I did what any novice mechanic would do - tore into it and figured it out myself. so far the conversion has about 2k miles on it and is doing well. It took two days and cost about 15 dollars - much better than 300 for axles. To my knowledge, I can lay claim to the only rwd, automatic '97 impreza brighton in the land. My next mission is to buy a set of blizzaks and find a lot of sandbags for the upcoming winter. As it is, starting on a hill is tricky in the rain, even with good tires. I would say however that it does turn better at the limit in the dry. It's the same as awd until you start accelerating again. It doesn't slide, but it rotates extremely well mid-corner. And when it does step out, it's still extremely controllable. these are just a few of my findings with a rwd impreza. all in all, I'm glad I did it. It may be a little less functional, but it's worth it for all the fun I can have now. If you are looking for info on the conversion or have questions, feel free to ask. Keep in mind though, it will probably be different with manual trannys or different generations, but I'll try to help.

this company has a nice one. Here is the reply!
It's a sleeve that goes in the center diff. It is $815CAD....about $660USD.
Shipping will be under $20 to anywhere in the US.
