Outer Limits 4x4 Board

HI ALL,
have a question, has anybody out there ever installed impeza rear diff into 1600 / 180b as i know the housings are identical but not too sure of the internals
any info would be helpful
where can i get an R200??

It's been done, and there is a lot of info on these out there.

R160, R180 and R200 are not identical housings, in fact the R200 is a fair bit bigger afaik. What you are probably thinking of is that an R160 in a subaru is the same as an R160 in a datto, which is correct except for things like the half-shafts. I think LSD is more common (but still not that common) in subarus.

You will find R200's in dattos as well as subies, too.

It depends what you're after, if you are looking for a change in ratio then you could just swap another R160 in, if you need something stronger then you might want an R180 or R200 but you might still want one from a datto for the half-shafts and possibly the axle assembly, as I am not sure you'll be able to use your exisiting R160 half shafts in an R180 or R200.

If on the other hand you are after LSD, good luck; I think they are pretty sought-after.

Anyway there is heaps of info on all this, eg:

To help you in your decision making, I had a R180 in a 980kg 1600 with a 2.4 stroker running 210hp at the rear wheels with no diff problems [strength wise] in the 5 years that I had it.

Cheers

mate had 3.9Lt in one no prob eather

agree the R180 is more than adequate for most high horsepower applications, they are fairly bulletproof.

go to http://www.ozdat.com/forums and search!!!

there's quite a big thread on it, not much, modded half shaft's are about all that's needed from memory, no strength gains, just ratio's and a viscous(?) LSD

most wrecker's that have old jap car's will have an R200, but new tailshaft, half shaft's and some massaging of the boot are needed

thanks for the info
all im trying to obtain is a limo,
just thought the subarus might be more readily available than an r180 / 200

Dont know what sydney datto shop's there are but give nisco in bayswater in melb a call, or in adel call datsport. either will have something in stock or could source it for you!
